If the hardness of Dalian auto parts exceeds the hardness of machine parts (lathe tools), it cannot be machined. The surface finish in the problem is 0.8. If it is Ra value, it can be regarded as precision machining. If it is RZ value, it is ultra precision machining. It is often more economical and easy to be vigilant against gross damage. Such as when finishing the tooth profile.

Its market share is about 2%; Ceramic cutting tools are widely used in high-speed milling, especially in the field of aviation difficult to machine materials, accounting for about 1% of the market share; The market share of superhard material PCD / PCBN is about 2%, mainly focusing on the processing of non-ferrous metals and ferrous metals.

Use an oscilloscope to observe the amplitude, phase and even presence of relevant pulsation signals, and use a PLC programmer to find out the fault position and cause in the PLC program. The faults in PLC program and processing program are usually equipped with alarm display. According to the displayed alarm number, the possible fault causes and troubleshooting methods can be known by comparing with the corresponding diagnosis instruction manual.

It makes it possible to detect the performance, overall dimensions and characteristics of raw materials, blanks and parts, the working position of processing and assembly, the working condition of equipment, the transmission of materials and parts, and the performance of products. Various amplifiers, converters, transmitters, display and recording devices promote the development of automatic detection technology. Many people need to replace parts when repairing or maintaining the vehicle, in order to save money.

They decide to replace by themselves, but they need to choose to buy parts at this time. When purchasing auto parts, we must pay attention to the details. When purchasing auto parts, in order to meet the needs of use.
