When cutting stainless steel, the appropriate chip breaking groove (roll) should be selected to control continuous chip. Usually, the whole arc or straight arc chip breaking groove (roll) should be used. The width of the chip breaker is Bn....
The amount of cutting has a great influence on the work hardening, cutting force, cutting heat, etc. in the processing of stainless steel, especially on the durability of the tool. Whether the selected cutting amount is reasonable or not wi....
Due to the poor machinability of stainless steel, there is a higher requirement for the cooling, lubrication, penetration and cleaning performance of the turning fluid. Commonly used turning fluids have the following categories: 1. Sulfuriz....
When it comes to ultra-precision electrode processing, many people will say that it is very simple. The machine is bought well, the tool is used correctly, the material is used well, the processing technology is refined, the amount of the lo....
The invention relates to a method for performing DRAM wafer testing using a test pin card. Background technique: DRAM has the need to reduce test costs during the testing process. Therefore, the same number of test needle cards is getting hi....
Superalloy is a kind of engineering material used at about 1000 C. It is widely used in aerospace, aviation and various heat treatment equipment. Since the high-temperature alloy contains many high-melting alloying elements such as Fe, Ti, C....
With the in-depth implementation of the magnesium alloy application development and industrialization project, enterprises have experienced many problems in actual production. Such as process and safety issues, this is because most of the do....
Guide: The criteria for easy tool withdrawal in part processing and design are as follows: After finishing the processing task of a processing surface, the cutting tool can leave the area conveniently, so as to avoid collision or damage of t....
There are processes of turning smooth stop and inner circle of smooth stator core when machining motor base. In order to make the air gap of the motor even, the iron core is pressed into the motor seat. In general, the method of finishing tu....
The base plane of the motor is an important benchmark for the connection of the motor and the supporting equipment, which directly affects the accuracy of the connection and the smooth level of the operation. In general, motor base plane mac....
