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

Summer tires can be filled with nitrogen to prevent punctures

In summer, there are relatively more accidents caused by flat tires. Some citizens fill the tires of their cars with nitrogen to prevent flat tires. Is there any benefit to tire nitrogen filling? Can a flat tire be prevented? Tian Jinsheng, secretary-general of the Motorsports Association of this city, introduced that if conditions permit, it is possible to fill the tires of your car with nitrogen, which can prevent tire blowouts to a certain extent.

According to experts, there are certain benefits of filling car tires with nitrogen. Nitrogen is not easy to expand and contract with heat, and has a small deformation range. When the temperature rises, the air pressure in the tires will not increase significantly, and the normal tires can be maintained for a long time. It also reduces the tire vibration on the road and improves the stability of tire driving. In addition, nitrogen filling can also reduce the noise during driving. If conditions permit, car owners can consider filling the tires of their cars with nitrogen, especially for vehicles that often run at high speeds, run long distances, and often drive on poor roads. It is worth noting that when filling with nitrogen, the original air should be released, and it is not advisable to mix air and nitrogen together, otherwise it will not play its due role.

In addition to the method of nitrogen filling, to prevent the car from puncturing the tire, the vehicle should also be inspected regularly. After entering the summer, the tire pressure should be appropriately reduced to maintain a normal level of tire pressure. In addition, the entire tire should be inspected to observe whether the tire has bulges and hidden injuries. If there is any bulge, it should be replaced in time to prevent sudden puncture. Pay special attention to the situation of the front tire. On weekdays, you should pay attention to the wear of the tire pattern and the aging of the rubber. If you find that the wear of the pattern has reached the design limit, you should replace the tire in time.

If the front wheel of the vehicle suddenly punctures during driving, the vehicle will immediately deviate in the direction of the puncture. The owner should immediately turn on the hazard warning flasher, and at the same time hold the steering wheel firmly with both hands, release the accelerator, and do not step on the brakes, and wait for the vehicle to slow down. , Pull over and stop again. If there is a puncture on the rear wheel, as long as the vehicle is not at a particularly high speed, the vehicle will not deviate seriously. After turning on the hazard warning flasher, the owner can control the steering wheel and gently step on the brakes to stop the vehicle slowly. Down.
