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

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

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

Summer car maintenance tips

In the hot summer, the car is running at a higher load, and the mechanical wear and aging fatigue will be worse than usual. Daily maintenance can make your car’s normal service life longer. Therefore, how to carry out summer maintenance work on the car in advance is very critical. Here are a few common summer maintenance tips for everyone.

1, engine maintenance

In summer, we should try to choose some higher viscosity oil, because the viscosity of the oil will change with the increase of temperature. When the temperature is higher, the viscosity of the oil will decrease, the oxidation resistance will be poor, and it will be easily deteriorated. The oil film formed inside the engine is thin and uneven, which is likely to cause failure. In addition, under the condition of ensuring sufficient lubrication, lubricating oil with corresponding viscosity should be selected according to the temperature range, engine temperature and actual vehicle conditions during use.

2, high temperature explosion-proof tire

Because the higher the temperature, the higher the air pressure inside the tire. In the hot summer weather, excessively high or low tire pressure can easily cause abnormal heat and instantaneous inflation of the tire. Therefore, in summer, pay special attention to frequently checking the tire pressure to keep it within the normal range. In addition, the tires are prone to overheating during long-term driving or high-speed driving in summer, and the air pressure increases at the same time. At this time, you should stop to dissipate heat, and it is strictly forbidden to bleed to reduce pressure or splash water to cool down. At the same time, due to the increase of rain in summer, to eliminate the impact of slippery roads on driving safety, it is necessary to check the tire pattern, including the tire pattern type and pattern depth. Generally speaking, manufacturers will set wear marks on tires. When the pattern is worn to the point that this mark is exposed, it means that we need to replace the tires.
