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

Analysis of the maintenance of 7 major parts of the car in winter

As the temperature continues to drop, how to do a comprehensive winter maintenance for your car has become a topic of concern to many drivers. Recently, the netizens in the QQ group of our newspaper's “Long Night Talking about Traffic” have come up with a set of strategies for “maintenance of 7 major components of a car in winter” by consulting relevant experts and combining their own car maintenance experience. I hope these strategies will help the readers and friends.

1. Car paint

In the early winter morning, there is a lot of dew, and the surface of the car is often very humid. If there are obvious scratches on the surface of your car, you should paint it in time to prevent the scratched parts from getting damp and rusty. In addition, when the season is changing, you should do a series of beauty care for the surface of your car from cleaning, polishing to waxing, sealing or coating.

2. Tire maintenance

Tires play a pivotal role in the safe driving of vehicles. Especially in winter, because the temperature is relatively low, the tires must be supplemented with air pressure to keep them within the specified air pressure range. At the same time, the tires should be checked for scratches, because the rubber tends to harden and become brittle in winter. It is easy to leak air and even puncture the tire.

3. Engine compartment

In winter, the driver should always check the engine oil, brake oil and antifreeze in the engine compartment to see if the oil is sufficient, whether it has deteriorated, and whether it is the replacement cycle. These oils are like the blood of your car, and must be replaced during the replacement cycle to ensure the smooth circulation of the oil.

4. Heating pipe and fan

In winter, the temperature is low and hoarfrost will appear in the car. In this season, you should pay special attention to whether the defrosting air outlet under the windshield is normal and whether the heat is sufficient. If there is a problem, you must solve it in time, otherwise, it will bring unsafe factors to your driving.

5. Air inlet or inlet grille, electronic fan

Always check whether there is any debris in the car vents, inlet grilles, and electronic fans. If there is debris, you can use a compressed air machine to blow away the dust. In addition, when the engine is cooling down, the above parts can be flushed from the inside to the outside with a water gun.

6. Battery

In winter, the electrode connection of car battery is the most prone to problems. When the driver checks, if there is green oxide at the electrode wiring, it must be washed away with boiling water. These green oxides will cause insufficient power in the generator and cause the battery to be in a state of lack of electricity. In severe cases, it will also cause the battery to be scrapped or the car Can’t catch fire.

7. Interior

Due to the high temperature and rain in summer, many bacteria breed in the carpet, floor glue and other hidden places in the car. With the advent of winter, car windows are no longer frequently opened, and the air in the compartment will become turbid, causing peculiar smells, and peculiar smells and bacteria will cause harm to human health. Therefore, it is necessary to love you during the season. The car undergoes a thorough sterilization and cleaning of the interior.
