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

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

Vehicle inspection and maintenance work must be done before self-driving tour

Self-driving travel is a very popular way of vacation nowadays. The Dragon Boat Festival holiday is coming soon, and it is another hot period for self-driving travel. It is a great time to bring your wife and bring friends and call friends. However, don’t forget to make preparations before departure. Among them, vehicle inspection is essential.

Then, how to do a good job in vehicle inspection and maintenance?

1. Power system

Check the engine oil and water tank level. If it is an automatic transmission model, it is also necessary to check whether the transmission mailbox is missing. If it is excessively consumed, it should be refilled in time.

If the self-driving trip is long, it is best to change the engine oil, because the engine’s high temperature work for several days may cause the oil to deteriorate. Also need to pay attention to whether the engine belt is loose. If you need to clean the engine and radiator on the way, remember to go to a professional car dealer for professional cleaning.

2, chassis system

The continuous impact on the chassis caused by the journey may change the four-wheel alignment, resulting in abnormal tire wear, so don’t forget to do a four-wheel alignment for your car according to the situation when you come back from the journey. If it vibrates all the way, it may damage the steering system. Check whether the steering gear ball head is loose. The screws of the chassis part should also be checked and tightened.

3, tire condition

Measure the tire pressure to keep the same tire pressure for all four wheels; ensure that the tires have the same running friction to ensure safe driving.

4, brake system

This is very important. Check carefully before departure. If there is an abnormal noise when you step on the brakes, you must go to a professional store to check and replace the brake pads. If braking occurs during driving, you must pay attention to it, and don’t get lucky.
