Structure and Principle of Operation 工作原理及结构

Principle of Operation 工作原理

The serial product applies “Electrical Discharge Machining” mechanism. It gets the auxiliary aid from electro-mechanically integrated product which combines Automated Control with Micro-Computers. The Machine Tool usually adopts “Molybdenum Wire” or “Hard Brass Wire” as the “Tool Electrode”. Under the “High Frequency Pulse Voltage Functions”, it utilizes the effect that it forms “Spark Discharge” after the liquid medium has been broken down. It instantaneously produces great volumes of heat energy in the Spark Channel. It melts or even gasifies the metal in the surface of the Work-Piece. With the joint action of the liquid medium, the metal has been rapidly eroded and removed. The Work-Piece which has been chucked in the coordinates Work-Table has been processed into various required shapes according to the pre-formulated program under the Micro-Computer Control.

本系列产品是应用“放电加工”机理，辅以自动控制及微机相结合的机电一体化产品。机床通常采用钼丝或硬性黄铜丝作为工具电极，在高频脉冲电压作用下，利用液体介质被击穿后形成火花放电，在火花通道中瞬间产生大量的热能，使工件表面的金属熔化甚至气化，加上液体介质的共同作用，而使金属被迅速蚀除下来。装夹于座标工作台上的工件在微机控制下按预行编制的程序被加工出各种所需的形状。

“Machine Tool Control System”, “Mechanical System”. The

Processing Documents” form “Computer-Input Machine Tool Control System” through programming. The “Control System” controls the “Machine Tool” to complete the program actions and therefore finishes the Processing Instructions. The “Mechanical System” is based upon the “Machine Tool Body”. It includes the “Coordinates Work-Table”, “Kinetic Wire System”, “Cooling System”.

由上图可见整个系统主要由计算机系统、机床控制系统和机械系统组成。加工文件通过编程形成计算机输入机床控制系统，并由控制系统控制机床完成程序的动作，以此完成加工指令。机械系统以床身为基础，包括坐标工作台、运丝系统、冷却系统。

The “Micro-Computer System” allocated by this Machine Tool is a new generation “Control System”. For details, please refer to “Use Description and Machine Tool Running System Parts”.

本机所配的微机系统是新一代的控制系统，详见〈使用说明书、电器部分〉。其主要由微机配上专用的插补控制软件及接口电路和步进驱动电路组成，由于采用了先进的CNC技术，所以具有良好的操作性。

Mechanical System Structure 机械系统结构

The Mechanical System Part of this “Machine Tool” is composed of the key elements such as the “Machine Tool Body”, “Work-Table”, “Kinetic Wire Device”, “Coil Holder” (including Taper Device), “Cooling System” etc.

本机床的机械系统部分由床身、工作台、运丝装置、线架（包括锥度装置）及冷却系统等重要部件组成。

Machine Tool Body 床身

“Machine Tool Body” is a basic part of the “Machine Tool”. If all these components have been installed in the body, it can guarantee the high accuracy to the whole system because of the enough rigidity and vibration-resistance. There are two “Hoisting Screws” mounted respectively in the fore-and-aft sides of the “Machine Tools” below DK7750 which have been produced by this Company. They function as hanging the “Machine Tool”. It can remove the “Hoisting Screws” after installation. The large-size Machine Tools use the “Hoisting Holes”. The “Supporting Feet” with the adjustable level have been installed in the bottom of the “Machine Tool Body”. 床身是机床的基础件。以上这些部件都装在其上，所以其足够的刚性与抗振性使整个系统有高精度的保证。本公司生产的DK7750以下机床，其床身前、后两面各装有两个起吊螺丝，其作用是吊装机床使用。起吊螺丝安装后可拆下，大型机床用起吊孔，床身底部装有可供调节水平的支承脚。

Work-Table

工作台

The Worktable is composed of two “Upper and Lower Tool Carriages” making relative cross movements and precise “Lead-Screw Drive Pair”. Please refer to Table 2 and 3 for the “Drive System”.

工作台是由二块相对十字运动的上下拖板及精密丝杠传动副所组成，其传动系统见图2和图3。

The Structural Formula of “V-Thread Drive” is as follows: (See Table 2) 三角螺纹传动的结构式如下（见图2）

X-Directional: Feed Pulse → Step-Motor E1→ Gear Pair Z1/Z2→ Lead-Screw M1 X向：进给脉冲→步进电机E1→齿轮副Z1/Z2→丝杠副M1 Y-Directional: Feed Pulse → Step-Motor E2→ Gear Pair Z3/Z4→ Lead-Screw Pair M2 Y向：进给脉冲→步进电机E2→齿轮副Z3/Z4→丝杠副M2

Kinetic Wire Device 运丝装置

It consists of the Motor, Coupler, “Wire Storage Tube”, “Gear Drive Components”, “Slide Plate”, “Kinetic Wire Base”, “Lead-Screw Pair” etc. Because of the action of “Left & Right Link Stoppers” and “Stroke Switch”, it implements the reciprocating movements to the “Electrode Wire” that has been coiled in “Wire Storage Tube” in order to complete cutting to “Work-Pieces”. 由电机、联轴器、贮丝筒、齿轮传动部件、滑板、动丝底座及丝杠副等组成。由于左右撞块及行程开关的作用，使缠绕在贮丝筒的电极丝实现往复运动，来完成对工件的切割。

Coil Holder 线架

“Coil holder” is a device which supports the “Electrode Wire”, adjusts the “Cutting Thickness” and carries out various “Taper Cutting”. It installs the “Electrode Wire” onto “Work-Piece” which has been chucked in the “Work-Table” through “Wire-Positioning Wheel”, “Conductive Device”, “Guide-Wheel Group”. “Conductive Block” electrifies “Electrode Wire” under action of “HF Pulse Mains”. The “Liquid Medium” ejected from “Liquid Injection Device” has been broken down to form “Spark Discharge” which completes the “Work-Piece Cutting”.

线架是用来支承电极丝，调节切割厚度及进行各种锥度切割的一个装置。它通过排丝轮，导电装置及导轮组，将电极丝引到装夹于工作台上的工件上。由于通过导电块在高频脉冲电源作用下，使电极丝带电，利用喷液装置喷出来的液体介质被击穿后形成火花放电来完成对工件的切割。

Because it acts to various “Structural Composition” of the “Coil Holder”, it is divided into “Fixed Coil Holder”, “Adjustable Coil Holder”, “Taper Coil Holder”.

由于作用不同线架的结构形成，通常有固定线架，可调线架及锥度线架之区别。

Fixed Coil Holder 固定线架

The “Upper and Lower Coil Holders” of such structural “Coil holder” have been fixed above the “Upright Column”. It can not be adjusted. It has the advantages of the fine Rigidity and sound Machining Stability. But its max. shortcoming lies in the small cutting range which can not be regulated. Therefore it has limitations for the product machining. At present, it has been gradually replaced by the “Adjustable Coil Holders”.

此种结构线架其上下悬臂固定于立柱之上，不可调节。其优点是刚性较好，加工稳定性也较好，但其最大缺点是切割范围较小，且不能调节，因此产品加工有局限性。目前已逐步被可调形线架所代替。

Elevated Adjustable Coil Holder 升降式可调线架

The “upper coil Holder” can move up and down along the “Upright Column” so that it can adapt to the spare machining with different thickness.

是使上悬架可沿立柱上下移动，以此来适应不同厚度的零件加工。

Tapered Type Coil Holder 锥度式线架

In fact, this Structure is the “Elevated Type” plus one “Taper Cutting Device”. The “Taper Device” produced by our company has the multiple specifications such as 6°, 12°, 15°, 30°, 60° etc. It can basically satisfy various requirements from vast consumers. With the

9

collocation of the corresponding “Control Device”, it can easily fulfill “X, Y, U and V Four-Shaft Linkage”.

这种结构实际上是升降式再加上一个锥度切割装置，本公司生产的锥度装置有6°、12°、15°、30°、60°等各种规格，基本上能满足用户的各种需要，配上相应的控制装置能很容易地实现X、Y、U和V四轴联动。

Technical Parameters 技术参数

Characteristic Model Stipulations 特性型号的规定

At present, DK77 serial goods produced by our company is mainly divided into three kinds of Model E, Model F, Model G according to different “Power Stroke” (Specification) and Structural Form of the Coil Holder.

Machine tool handling and installation 机床的搬运和安装

Machine Tool Handling and Hoisting 机床的搬运和吊装

Machine tool handling can be hoisted or use the lift-truck. Please refer to diagram 4 for outer packing box hoisting. If there is no packing box, please refer to diagram 5 with the utilization of double ends of machine tool body and four hoisting screws for lift. Please be noted that the hoisting screw should be tightly wrenched and the face tightly stuck to the body. Otherwise it easily breaks the screw root and causes the unnecessary accidents. As for the large-size machine tool above Dk7763, it should use the enough intensity hoisting bar. Soft materials should be filled between the wire rope and machine tool contact so that it will not damage the outer appearance. Un-smooth circumstances such as jolt, tilt, impact etc. should be avoided in the handling.

机床的搬运可用吊装，也可用铲车。当有外包装箱吊运时可见图4，若无包装箱则可利用床身两端，四只起吊螺丝起吊，见图5。注意起吊螺丝必须拧紧，其端面必须紧贴床身，否则螺丝根部容易折断，造成不必要的事故。对于Dk7763以上的大型机床，必须用具有足够强度的起吊棒。钢丝绳与机床接触处要填放软性物质，以免损伤外观。搬运中应避免颠簸、倾斜、撞击等不平稳现象。

Machine Tool Installation 机床安装

It should keep a clean, dust-free installation environment without vibrating source; corrosive gas and large wattage electrical equipment interference. It better controls 20±5℃ to the operating environment temperature.

安装环境应清洁，无粉尘、无振动源，无腐蚀气体，无大功率电气设备干扰。建议工作环境温度最好控制在20±5℃。

As far as the “Installation Direction of the Machine Tool” is concerned, it is better for the operator to face the “Natural Light Source”. After the initial placement of the Machine Tool, firstly remove the “Locking Blocks” on both ends of the “Guide Rail” and replace them with the Machine Backups, then wash the key “Drive Members” such as “Lead-Screw Pair”, “Guide Rail”, “Guide Wheel” etc. by the clean kerosene and immediately coat with clean HJ-30 Lubricant in order to prevent from rusting. Relying on the adjustable Screws below the “Machine Tool Body”, it should not exceed 0.04/1000 requirements for the lateral and longitudinal directions of the “Level Gauge” in the “Work-Table”. The Machine Tool should have the reliable connection with the “Protective Ground System” for purpose of ensuring the safe use.

机床安装方向尽量使操作者面对自然光源。机床初步安放后，应拆去导轨两端锁紧块，换上随机带的挡块，然后用干净煤油清洗丝杠副、导轨、导轮等重要传动件，要立即擦上清洁的HJ-30机油以防生锈。借助床身下面的调整螺钉，使水平仪在工作台纵横二个方向均不得超

13

过0.04/1000的要求。机床应与保护接地装置可靠连接，以确保使用安全。

Coil holder adjustment 线架调整

Height regulation 高度调整

Please refer to table 2 or table 3 见图2或图3

Loosen the platen screw at the side and in the rear part of the coil holder, then rotate the elevation lead-screw to adjust the height of the upper coil holder in order to adapt to various thickness of the machining parts, finally tightly wrench the platen screw and positioning screw at the side and in the rear part.

拧松上悬臂侧面与后面的压板螺丝，然后转动升降丝杠来调节上悬臂的高度，以适应加工零件的不同厚度，最后再拧紧侧面与后面的压板螺丝与定位螺丝。

Verticality regulation between electrode wire and the work-piece 电极丝与工件的垂直度调整

It can use the “Precision Right-Angle” or “Model DF55-J50A Electrode Wire Verticality Corrector” (Please refer to “Use Description of Corrector” for the use methods) to correct the none verticality between “Electrode Wire” and “Work-Piece”. Firstly loosen the “Holding Screw” of two “Guide Wheels” in the front end of the “Coil Holder”, then slightly adjust the left and right positions of the “Guide Wheel” in order to fulfill the “Electrode Wire Verticality”. This method

17

is only fit for “E type Vertical Wire Holder”.

可用精密直角或DF55-J50A型电极丝垂直校正器（使用方法见校正器的使用说明书）来纠正电极丝与工件的不垂直。可先拧松悬臂前端二只导轮的紧定螺钉，再微量调节导轮左、右位置，以达到电极丝的垂直度，这种方法仅仅适用E型直升丝架。

As to the “Wire Holder” mounted with “F type or G type Taper Head”, or with the Taper Head, it is more easy to regulate the verticality of the “Electrode Wire”. Only the slight adjustment of “U Shaft” and “V Shaft” positions can fulfill the verticality requirements.

对于装有F型或G型锥度头的丝架，锥度头的丝架，其电极丝的垂直度调整就容易多了。只要稍微调整U轴和V轴的位置，即能实现垂直要求。

第10页

Taper Cutting Adjustment 锥度切割的调整

Taking a small “Taper Head” produced by this Company as an example, it describes the importance of reasonably choosing the relevant parameters. The “Small Taper Head Principle” can be simplified into what is shown in Table 8:

以本公司一小锥度头为例来说明合理选用有关参数重要性。小锥度头原理可简化成图8所示：

Therefore it get the following “Relational Expression”: 由此可得下列关系式

Among which A is oblique angle = taper angle / 2 式中a为斜角=锥角/2

U and V are U-directional and V-directional moving volume of the “Upper Guide Wheel”. H is the central distance between “Upper and Lower Guide Wheels”.

U和V为上导轮的U向和V向的移动量，H为上下导轮的中心距

It draws the conclusion from the above “Relational Expression” that 由上式可见：

U↑（or V↑）, then a↑, otherwise it results in a↓ U↑（或V↑）则a↑，反之则a↓

H↑ then a↓, otherwise it results in a↑ H↑则a↓，反之则a↑

Therefore in the same specification of the taper heads, only the reasonably regulation of U (or V) and H numeric values can get the ideal cutting effects.

所以在同一规格的锥度头上，只要合理调整U（或V）和H的数值，就能得到理想的切割效果。

18

It has already calculated the upper limit value of U and V two parameters in design. At present, we take the following example: When our commonly-used U (or V) taper head whose moving volume is 30mm, what is the proper central distance H adjustment between upper and lower guide wheels while processing the work-piece with 12° taper and 120mm thickness?

U和V这二个参数的上限值在设计时已计算好。现举本公司一常用U（或V）的移动位置为30mm的锥度头为例，来核算一下要加工锥度为12°，厚度为120mm的工件其上下导轮中心距H调整到多少为合适？

It draws the conclusion from the formula (1): 由公式（1）可知

Therefore as long as central distance H≤142.72mm, it can process the work-pieces with 12° taper. If H≥142.72mm, then it can not process 12° taper. As material thickness 120mm falls into its range, so it allows the processing.

由此可见只要中心距H≤142.72mm就能加工出12°锥度的工件，若H≥142.72mm，则12°的锥度就加工不出来了。因材料厚度120mm在其范围内，因此是允许加工的。

Work-table regulation 工作台调整

The work-table had been driven by step-motor. It completes X and Y directional movements through the gear stand and lead-screw pair. The transmission of the large specification of this series adopts the high precision non-clearance ball lead-screw pair. Their clearances have been regulated when they leave the factory. Therefore it is not necessary for the customers to make regulation by their own. The small specification products utilize the high accuracy slide lead-screw pair. Their clearances have been fulfilled through adjusting one auxiliary nut in the combined nuts. Please refer to diagram 9:

工作台是由步进电机来驱动，通过齿轮架及丝杠副来完成X、Y两个方向的运动。本系列的大规格产品其传动采用高精度无间隙的滚珠丝杠副，它们的间隙出厂时都已调整好，客户不必自行调整。小规格的产品采用高精度滑动丝杠副，它们的间隙是通过调整组合螺母内的一只副螺母来实现的，见图9。

Lead-screw clearance regulation methods: 丝杠间隙调整法

The ex-factory lead-screw clearance has been elaborately adjusted during the assembly process. It has been operated under the best conditions. Through a period of use, the nut will possibly have the slight wear. Therefore the gas of lead-screw pair will be enlarged. It needs the self-regulation from the consumers too.

出厂时的丝杠副的间隙在装配时已通过精心调整，都在最佳状态下工作，经过一个阶段使用，螺母可能为出现微量磨损，因此丝杠副的间隙会增大，这时用户可以自行调整：

Check whether the Nut has been tightly fixed into “Nut Base Combination Face B” or not. Retention Screw 5.

检查螺母与螺母座结合面B应贴紧，紧固螺钉5。

Press “ENGAGE” key in the control keyboard, shake the work-table hand wheel to check whether the step-motor has been engaged or not. Hold the scale disk by hand and wring it slightly, examine that if there is any left or right loosening of scale value with comparison to “0” level of graduation mark. The lead-screw pair clearance should be regulated for any loosening. (See table 9) The adjusting methods are as follows: 按下控制键盘的电极吸键，摇动工作台手轮检查步进电机是否吸住，手握刻度盘并轻轻拧动，检查刻度值相对“0”位刻线有无左右松动，若有松动就应调整丝杠副间隙（见图9）调整方法如下：

Firstly loosen two hexagon socket screws 6, then rotate clockwise the auxiliary nut 2 to reduce clearance between lead-screw and the whole combined nut. (Anticlockwise rotation is for clearance increase) Then tightly screw in two bolts 6, it is forbidden to touch bolt 5 during the clearance adjustment.

先松开两内六角螺钉6然后顺时针转动付螺母2，使整个组合螺母与丝杠的间隙减少（逆时

20

针转动则增大间隙）然后再拧紧两个螺钉6，调整间隙时不许动螺钉5。

Left and Right Link Stopper Adjustment (See Table 10) 左右撞块的调整（见图10）

Properly adjust the positions of the left and right “Link Stoppers” according to the “Coiled Electrode Wire Length” so that it can just touch the “Stroke Switch” in order to fulfill the reciprocating movements of the “Wire Storage Tube”.

根据缠绕好的电极丝长度，适当调节好左右二撞块的位置，使其刚好能触及行程开关，实现贮丝筒的往复运动。

Because the high rotating speed “Wire Tube” transfers the same high rotation rate to the “Lead-Screw” with frequent commutating, therefore its “Lead-Screw Pair Wear” is much larger than that of the “Worktable Lead-Screw Pair”. For this reason, it should timely well-adjust the clearance in order to keep its high kinetic accuracy. Its adjusting methods are the same as the “Work-Table Lead-Screw Pair Regulation”. Here we make no mention of it any more. 由于高转速的丝筒传递给丝杠的转速也很高，且换向频繁，所以其丝杠副的磨损远大于工作台的丝杠副。因此要及时调节好间隙，使其保持较高的运动精度，其调节方法与工作台丝杠副调节相同，此处略去不谈。

Adjustment of the Guide Rail Clearance 导轨间隙的调节

Because of some unfavorable factor influences in the motion, though a period time of running, the “Electrode Wire” is loosened or tightened in single side of the “Wire Tube”, it is very harmful to the cutting. And it seriously influence the cutting precision too. Therefore it should properly adjust the bolts 2 in the “Guide Rail Regulative Plate 1” in order to increase the running accuracy. It can improve the single side loosening or tightening as well. (See Diagram 11) 由于运动中的某些不利因素影响，经过一段时间的运行，使电极丝在丝筒上出现单边松紧现象，这是切割中的大忌，它严重影响切割精度，此时若能适当调整导轨调节板1上几个螺钉2，以提高运行精度，就能改善单边松紧现象。（见图11）

Electrode Wire Coiling 电极丝绕装

Respectively move the left and right “Link Stoppers” to both ends before machine-start. 开机前将左右撞块各移向两端。

Machine-operate or manual-operate the end position of “Wire Tube” near “Coil Holder Guide-Wheel Center”

机动或手动将丝筒终端位置走至悬臂导轮中心附近

Coil the “Electrode Wire” into a proper “Core Rod”, one end of the “Electrode Wire” goes from “Wire-Positioning Wheel” to “Wire Tube”, it has then been pressed by bolt. After evenly coil the wire for several circles, swing the “Wire Tube Handle” by one hand (it can also be machine-operated), hold the “Core Rod” by another hand, put certain “Drag Force” onto “Electrode Wire Disk”, coil the “Electrode Wire” onto another end of the “Wire Tube”, then stop the Machine Tool and cut off the “Electrode Wire” according to the needed “Wire Mounting Volume”, then put the “Electrode Wire” onto “Guide Wheel”, “Conductive Block”, “Guide-Wheel Water-Jet Nozzle” etc., then the “Electrode Wire” goes down to “Lower Coil Holder Wire-Positioning Rod”, it returns to “Wire Tube” and has been tightly pressed into it. Depending on the proficiency degree of operation, it also has other “Wire-Mounting Methods”. We hereby do not go into details any more.

取电极丝盘串于一合适的芯棒上将电极丝一端串过排丝轮后缠绕到丝筒上用螺钉压住，均匀缠绕几圈后，然后一手摇动丝筒手柄（也可以机动）一手拿住芯棒，并施于一定阻力于电极丝盘上，将电极丝绕至丝筒另一端，根据需要的上丝量，停机剪断电极丝，将电极丝挂上导轮、导电块、导轮喷水嘴等，最后往下悬臂挡丝棒，回到丝筒上并压紧，视操作熟练程度还有其他上丝方法，这不再一一介绍。

Well-adjust the left and right link stoppers according to the cutting requirements. 根据切割要求调整好左、右撞块

While mounting the “Electrode Wire”, please pay close attention to the “Rotating Direction” of “Wire Tube” and “Moving Direction” of “Tool Carriage” in order to prevent the “Electrode Wire” from rushing out of Stroke. (Please be noted to take off “Swing Handle” in staring “Kinetic Wire Motor” in order to prevent it from rushing out and hurting the people.)

22

上丝时注意丝筒转向和拖板移动方向防止冲出行程（注意开运丝电机时必须取下摇手柄，以防飞出伤人）。

When special circumstances occur such as the “Stroke Switch” is out of order etc., the “Wire tube” will dash out of the Stroke and cause separation between Nut and Lead-Screw. By this time, it should immediately shut off the “Control Switch” of the “Wire Tube”, slightly push forward the “Tool Carriage”, make the Lead-Screw contact the Nut End. (It is forbidden to use the over-large strength, otherwise it will damage Nut.) Meanwhile shake the “Wire Tube” by hand to slowly wrench “Lead-Screw” into Nut. 遇到特殊情况（如行程开关失灵），丝筒就会冲出行程造成丝杠与螺母脱落，此时马上关闭丝筒控制开关，然后轻轻推动拖板，使丝杠接触螺母端部（注意，用力过大会损坏螺母），同时用手摇动丝筒使丝杠缓缓拧入螺母即可。

Wire tightening wheel is used to tighten the wire by hand. After a period time of use, the electrode wire will be stretched and loosened because of fatigue. By this time, it needs to use the hand-operated wire tightening method to make the re-tensioning. Please pay attention to use the even strength.

紧丝轮用于手动紧丝，电极丝经过一段时间使用后，因为疲老产生拉长而变松，此时可用手动紧丝方法可重新张紧，注意用力要均匀。

Guide Wheel Adjustment 导轮的调整

As it is as high as 11 meters / second of “Line Speed” of “Electrode Wire” which has been installed in “Guide Wheel and Wire-Positioning Wheel Assembly”, therefore it is also as high as 7000r.p.m～8000r.p.m. “Rotating Speed” to “Guide Wheel and Wire-Positioning Wheel Assembly”. So it requires high “Kinetic Accuracy” to them. “Wheel Guide and Wire-Positioning Wheel” should be of light weight, little inertia, fine wearability, sound insulation, good water-resistance. Because it has special function in the cutting process, therefore it is vital to “Work-Piece Accuracy and Roughness” etc. And it is extremely important to their adjustment. Please refer to 13 for the “Regulating Method”. “Radial Jump” of “Guide Wheel” (require 0.005) has mainly been controlled in the packaging.

导轮及排丝轮组件由于架在其上的电极丝线速度高达11米/秒，所以导轮与排丝轮组件转速高达7000～8000转/分，这就要求它们有很高的运动精度。导轮及排丝轮必须重量轻，惯量小，且要耐磨、绝缘、防水。由于其切割过程中起到特殊的作用，对工件精度、粗糙度等至

23

关重要，所以它们的调整就显得尤为重要。调整方法见13，导轮的径向跳动（要求0.005）主要在其组装时就已得到了控制。

“Axial Displacement” of “Guide Wheel” (Allowance 0.002) mainly regulates Nut 1 and Nut 2. It should not only ensure the flexible rotation of “Guide Wheel”, but also have no “Axial Displacement” after the adjustment. It should add the enough “Lubricating Grease” in renewing the new “Guide Wheel” and Bearing.

导轮的轴向串动（允差0.002）主要是调节螺母1和螺母2，调节后既要保证导轮转动灵活，又要无轴向串动。更换新导轮和轴承时则必须要加足高速润滑脂。 Nut 螺母

Start “High Frequency” to select “Electrical Parameters”, the consumer can make choice according to the requirements towards “Cutting Frequency” or “Surface Roughness” etc. (For detailed information, please refer to “Pulse Mains Sub-Manual of this Description”.) During the

25

electrode wire cut-in process, please relatively increase the distance of “Pulse Space”. And re-adjust the “Pulse Space” when it has stable conditions after Cut-in so that the “Machining Current” can meet the demands. 开高频选择电参数，用户可根据对切割频率或表面粗糙度等要求来选择（详见本说明书的脉冲电源分册），电极丝切入时请把脉冲间隔相对拉开，待切入后稳定时再调节脉冲间隔，使加工电流满足要求。

Rotate “Wave-Form Switch” in “Control Cabinet” to “Automatic Machining Step”, start “Program Running”, i.e. start “X, Y Feeding Switch”, (U, V Feeding Switch should also be started for Taper Machining). When it enters into Cutting, regulate “Potentiometer Rotary Button”, observe “Machine Tool Amperometer” to stabilize the Pointer. (It allows only a little sway of Pointer). 将控制柜上的波段开关旋到自动加工档，启动程序运行，即开启X、Y的进给开关，（若有锥度加工还应开启U、V进给开关），进入切割时，要调节电位计旋钮，观察机床电流表使指针稳定（允许指针略有晃动）。

After the Machining Completion, firstly shut off “Pulse Mains”, then switch off “Water Pump Power Supply” and “Kinetic Wire Tube Switch”. (Please be noted that “Wire Tube” should be shut off immediately after commutating. It is forbidden to close it after long time of commutating.) To check whether “X, Y Coordinate” have reached the “End Point” or not. If they have not reached “End Point”, it should examine if there is something wrong with Program or “Control Cabinet”.

加工结束应先关闭脉冲电源，然后关闭水泵电源，再关闭运丝筒开关（注意应在丝筒换向后迅速关闭，不要在换向后太久关闭），检查X、Y座标是否到终点，若未到终点就应检查程序是否有错或控制柜是否有故障。

Points for Attention: 注意事项

Reasonably regulate the “Feeding Speed” according to “Work-Piece Thickness, Material Hardness” until it stabilizes Amperometer. If it is not sure, it can have the trial cutting first and then implement the formal cutting after well-adjustment.

根据工作厚度，材料硬度要合理调好进给速度，使电流表稳定为止，如没有把握，可先行试割，待调好后再正式切割。

If it is not sure about the “Program Formulating” to “Complex Spares”, it can firstly implement the trial-cutting to thin sheet.

对于复杂零件的程序编制如无把握，可先用薄板试割。

If there is short-circuit circumstances in cutting such as none spark, none feeding cut etc., it can be removed by “Short-Circuit Backspace”. In addition, please don’t interrupt the operation to the best of the operator’s abilities, otherwise it will have “Machining Trace”. 切割中出现短路现象，（无火花、无进给切割）可用短路回退排除，另外在切割中应尽量不要操作停机，以免出现加工痕迹。

Operational Description to Machine Tool Running System 机床电器操作说明

Plug in 380V three-phase AC mains, then turn on “Main Power Supply Switch” in the left of “Machine Tool Running System Cabinet”, it is bright to “Main Power Supply Indicating Lamp”. “Wire-Traveling Motor”, “Water-Pump Water” have respectively been controlled by “Two-Group Press Button”. Green for Open and Red for Shut. “Indicating Lamp” is bright under “Open Conditions” and dark under “Shut Conditions”. We hereby remind the consumers that when “Mode Switch Lamp” is under “Shut Conditions”, “Broken-Wire Protection” and “Machine Stop after Machining” will give function.

接入380V三相交流电源，然后拉起电器箱左边的总电源开关，这时总电源指示灯亮。走丝电机、水泵电机分别由二组按钮控制，绿色为开、红色为关，开启时指示灯亮，关闭时指示灯灭。要提醒用户的是只有当模式开关灯在关的状态时，断丝保护及加工完停机起作用。

Pulse Power Supply 脉冲电源

This power supply is composed of “Master-Oscillating Circuit”, “Pulse-Width Regulating Circuit”, “Clearance Regulating Circuit”, “Power Amplification Circuit”, “Commutating Circuit” etc. 本电源由主振电路、脉宽调节电路、间隙调节电路、功率放大电路和整流电路等构成。

“Master-Oscillating Circuit” produces dominant frequency pulse by “Crystal Oscillator”. It outputs wave-release pulse through “Frequency-Division Circuit”. When the Switch chooses “Rectangular Pulse Wave-Form”, “Square Wave” inputs “Pulse-Width Regulating Circuit”. By this time, “AND gate” output wave-form has been regulated by the required Switch through “Pulse Width” and “Clearance Adjustable Circuit”. “Pulse Width Regulation” has been selected through “Four Single-Pole Single-Throw Switch”. After Wave-Form has been pre-amplified, it drives “Power Amplification Tube” and outputs the tidy and stable “Machining Signal”. 主振电路由晶体振荡器产生主频脉冲，经分频电路输出放波脉冲。当开关选择矩形脉冲波形时，方波输入脉宽调节电路，此时，与门输出的波形是经脉宽和间隙调节电路按所需开关调节。脉冲宽度调节由4只单刀一掷开关选择，调节量为4μS（正常时）或8μS（倍宽时）。脉冲间隙由4只单刀一掷开关选择。波形经前置放大后，驱动功放管，输出稳定整齐的加工信号。

“Power Amplification Circuit” adopts the imported VMOS Tube. Six “Power Amplification Switches” are available for work selection.

功率放大电路采用进口VMOS管，六只开关选择工作。
