Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

Elimination of Gear Backlash in CNC Machining Feed System

Elimination of Gear Backlash in CNC Machining Feed System   The transmission gear in the feed system of the CNC machining machine tool must eliminate the transmission gap between the meshing gears as much as possible, otherwise the motion will lag behind the command signal after each reversal of the feed system, which will affect the machining accuracy (accuracy) ). There are the following two common methods for CNC machining machine tools to eliminate the transmission gear gap.   1. Rigidity adjustment method   The rigid adjustment method is an adjustment method that cannot be automatically compensated for the tooth side clearance after adjustment. Therefore, the pitch tolerance and tooth thickness of the gear must be strictly controlled, otherwise the flexibility of the transmission will be affected. This adjustment method has a relatively simple structure and a better transmission rigidity.   (1) Eccentric shaft adjustment method   As shown in Figure 610, the gear 1 is mounted on th

The material selection and machining accuracy of the worm gear are also very important. Use 10P polyoxymethylene (POM), or use glass fiber reinforced nylon or reinforced polycarbonate (PC). However, pOM has good comprehensive performance, high bowing, rigidity, impact, fatigue, and creep resistance. In particular, it has outstanding fatigue resistance and is easy to form. It is the best among thermoplastic engineering plastics. It has a small and stable friction coefficient, low water absorption, good dimensional stability, and low price, so it is our best choice.

In order to buffer the impact force generated by starting in the forward and reverse directions and ensure the life of the transmission parts, the transmission disc needs to be equipped with a rubber transmission disc with good oil resistance, wear resistance, high bow change and good elasticity under high temperature and low thirst. The structure size is matched with the worm gear. , Embedded in the worm gear. The material is nitrile butadiene rubber with excellent oil resistance, and its heat resistance is also better than natural rubber and nitrile rubber. Matched with the rubber drive disc and embedded in the worm wheel is a metal drive disc with 3 uniformly distributed on the disc.

Motor drive disc Five-window motor noise cut-off system When electromagnetic design, we first consider the suppression or reduction of motor noise. In terms of equipment, the armature bearing position and the matching of the bearing chamber are also required. Choose low-noise copper-based (or iron-based) oil-impregnated bearings, and choose copper: ink brushes. The matching gap between the carbon brush and the brush holder should be no more than 0.1lnrn on one side. During the trial operation, the contact surface of the carbon brush should be >70%. The surface of the commutator on the armature should be controlled within 0.01m. In addition, the manufacturing precision and matching clearance of the worm and worm gear, and the axial clearance of the motor should be strictly controlled.
