Brief summary to the machine tool running system and control system 电器控制系统概述
“Contactor Relay” is the main component of “Wire-Cutting Running System” and “Machine Tool
37
Running System” Parts which have been produced by this Company. It adopts “Simens” Running System which is a famous brand in the world. In this way, it greatly increases the service life of the “Running System”. “HF Pulse Mains” takes “Crystal Oscillator” as the
“Oscillating Source”. It has the extremely stable frequency. The complete set of the “Running System” adopts digital integrated circuit to produce the Pulse. In this way, it guarantees the long-term stable running of the “Power Source”. 本公司生产的线切割电器、机床电器部分的主要器件接触器式继电器，采用世界名牌西门子电器，这样使电器的使用寿命有了很大的提高，高频脉冲电源以晶振为振源，频率极其稳定，整套电器全部采用数字集成电路来产生脉冲，这样保证了电源能长期稳定的运行。
Machine tool running system 机床电器
Machine tool running system mainly consists of the machine tool running system switch box, stroke switch, wire-traveling motor, water pump motor, X and Y step-motors, U and Y step-motors with taper. The machine tool running system utilizes the contact of the contactor to control the running of the machine tool and other running systems. It uses the circuit-breaker and fuse to function as protection.
机床电器主要包括机床电器开关箱、行程开关、走丝电机、水泵电机、X、Y步进电机，及带锥度的U、Y步进电机。机床电器是利用接触器的触点来控制机床及其它电器的运行，并采用断路器、熔断器作保护。
“Kinetic Wire” in “Wire Storage Tube” has been driven by “Motor M2”. “X and Y Tool Carriage” have respectively spurred on by “X and Y Step-Motor”. There are “Four Tool Carriages of X, Y, U, V” for “Taper Machine Tool”. “U and V” have respectively driven by “U and V Step-Motor”. Emulsion has been supplied by “Water Pump Motor M1”.
贮丝筒的运丝由电机M2带动，X、Y两个拖板分别由X、Y步进电机带动，锥度机床有X、Y、U、V四个拖板，U、V分别由U、V步进电机带动，乳化液由水泵电机M1供给。

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。
