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

Anti-vibration design for automobile off-road operation

Anti-vibration design. For the strong vibration environment where the car is in off-road operation, the system adopts damping measures such as aviation damping pads on the control box; at the same time, the system adopts various aspects such as device selection, circuit board connector design, and welding process. The anti-vibration performance is fully considered to ensure the reliable operation of the system.

Full shielding and grounding wiring technology is mainly used to solve the interference from space (may also come from the outside of the system or from the inside of the system) through a good grounding system, shielding system and layout design. This system selects highly integrated peripheral devices, all equipped with special metal shielding shells; all other electronic devices (including connecting wires) can use similar shielding methods to ensure that the system is free from interference.

The system prototype has achieved all functions and technical and tactical indicators in accordance with the design requirements. Do a lot of stability and reliability experiments on the components and the whole machine. The onboard performance test and user trial show that the system is advanced in technology, excellent in performance and reliable in operation. The air-cooling adjustment of the engine is changed to the maximum, the wear particles are clearly visible, and particles such as impurities, cutting, and oxidation can be distinguished. Spherical particles still occupy a certain proportion.

Large-scale road maintenance machinery has been widely used in the whole road. It can give full play to the comprehensive advantages of the whole road integration, and use modern communication technology to establish a monitoring network and detection database throughout each user unit, realize the interconnection and mutual visit of monitoring information, and promote the detection and discrimination standards Confirm as early as possible. In order to reduce the consumption of lubricating materials and to ensure the normal operation of the engine, it is necessary to insist on doing a good job in the daily maintenance of the car, improve the quality of maintenance and use lubricating materials rationally.
