Therefore it is called “Adjustable SmallTaper Coil Holder”.F型——线架高度可调节且配以6176。 Upper Limit Specifications and so on.G型——线架高度可调节且配以由公司专利的带跟踪喷液的大锥度切割装置。The Model Composition and Representative Meaning are in line with Standards JB/T7445 and 294.型号组成及代表意义依据标准JB/T744294。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。Machine Tool Installation机床安装It should keep a clean, dustfree installation environment without vibrating source。5℃。机床应与保护接地装置可靠连接，以确保使用安全。The contents include the following:内容有：The “Control Cabinet” should have more than ten minutes’ normal operation.控制柜必须正常工作十分钟以上；It should have the normal operation for various parts of the “Motion Pair” in the Machine Tool.机床各部分运动副工作正常；No Error in “Pulse Mains” and “Machine Tool Running System Operation”脉冲电源与机床电器工作无失误；It should have sensitive action of various “Stroke Switch Contacts”.各个行程开关触点动作灵敏；Smooth flow of the “Working Solution” in various “Inlet and Outlet Pipes” with normal pressure, the “Working Solution” should wrap “Molybdenum Wire”. 工作液各进出管畅通无阻，压力正常，工作液裹住钼丝。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3Loosen the platen screw at the side and in the rear part of the coil holder, then rotate the elevation leadscrew 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。只要稍微调整U轴和V轴的位置，即能实现垂直要求。 taper and 120mm thickness?U和V这二个参数的上限值在设计时已计算好。 taper. As material thickness 120mm falls into its range, so it allows the processing. 由此可见只要中心距H≤176。Worktable regulation工作台调整The worktable had been driven by stepmotor. It pletes X and Y directional movements through the gear stand and leadscrew pair. The transmission of the large specification of this series adopts the high precision nonclearance ball leadscrew 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 leadscrew pair. Their clearances have been fulfilled through adjusting one auxiliary nut in the bined 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。Press “ENGAGE” key in the control keyboard, shake the worktable hand wheel to check whether the stepmotor 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 parison to “0” level of graduation mark. The leadscrew 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 leadscrew and the whole bined 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。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。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 LeadScrew. By this time, it should immediately shut off the “Control Switch” of the “Wire Tube”, slightly push forward the “Tool Carriage”, make the LeadScrew contact the Nut End. (It is forbidden to use the overlarge strength, otherwise it will damage Nut.) Meanwhile shake the “Wire Tube” by hand to slowly wrench “LeadScrew” 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。Machineoperate or manualoperate the end position of “Wire Tube” near “Coil Holder GuideWheel 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 “WirePositioning 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 machineoperated), 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”, “GuideWheel WaterJet Nozzle” etc., then the “Electrode Wire” goes down to “Lower Coil Holder WirePositioning Rod”, it returns to “Wir
