20、 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

21、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

22、” 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，

The “Liquid Medium” ejected from “Liquid Injection Device” has been broken down to form “Spark Discharge” which comple

31、tes 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”, “Tape

32、r 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. shortc

33、oming 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 Adju

34、stable 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 Devic

35、e”. 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 collocation of the corresponding “Control Device”, it can easily fulfill “X, Y, U and V Four-Shaft Linkage”.这种结构实际

36、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

Please refer to diagram 4 for outer packing box hoisting. If there is no packing box, please refer to diagram 5

44、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

45、 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

46、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 205 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
