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

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

Introduction to methods to extend vehicle life and mileage

Is car maintenance calculated based on the date of use, or based on the number of kilometers traveled? This is something that many car owners struggle with when the maintenance period is approaching. Everyone has different usage habits and different road conditions. It is difficult to set a fixed standard for the vehicle maintenance period. Car maintenance is usually measured by the number of kilometers used. It is more reasonable. In addition, the maintenance cycle of auto parts Keep in mind that cleverly combining the maintenance cycle and the number of kilometers traveled during maintenance is more conducive to prolonging the life of the vehicle.

Vehicle tires should be checked once a month

Only by maintaining the car in time, can we reduce wear, avoid breakdowns, and ensure performance. Fan Liangyin believes that car owners should pay attention to the appearance of vehicles such as car light bulbs and mirrors before starting the vehicle. If the car tire has signs of wear, the owner needs to check it carefully and check whether the tire has bulges, aging cracks, etc. The inspection of the tire is usually done once a month. If the vehicle is driving and you feel that the tire has collided with a foreign body, you need to inspect it immediately. When checking the tires, you should also check the car chassis for oil leakage. You can also check whether there are traces of oil leakage on the original parking ground after the vehicle is shifted. If there is, a comprehensive inspection and maintenance is required.

Important bolts are inspected every six months

In the process of car maintenance, you also need to pay attention to all aspects of details. Ordinary family cars are maintained every 3 months or 5000 kilometers. However, many car owners did not take into account the actual cost and did not maintain them on schedule. In this case, car owners need to pay more attention to the maintenance cycle of parts. For some drum hand brake shoe clearance and wheel brake wear, if the wear mark is reached, the brake shoe should be replaced, and the important bolts of the chassis should be fixed. Even if the distance traveled by the vehicle does not reach the number of maintenance kilometers, but more than half a year You should also check the maintenance period.

Idle vehicles are more prone to aging

Auto parts that have been idle for a long time will age faster. Idling a car can easily cause problems with the battery, as well as oxidation of the engine oil and aging of the rubber. Cars that have been idle for a long time should pay attention to checking the use of parts regularly.
