Shenzhen precision parts processing mainly has more essence, fine boring, milling, grinding and fine grinding process.
You know shenzhen precision parts processing methods, how to operate it in the process, how much does it have the gap, we take a look at.
Shenzhen precision parts processing methods: (1) essence and boring: most aircraft precision of light alloy (
Aluminum or magnesium alloy, etc. )
Parts in this way more processing.
Generally with natural single crystal diamond tool, the blade circular arc radius less than 0.
(2) grinding: using the mating parts on the principle of mutual abrasion of the processed surface irregular convex part of the selection process.
Particle diameter, cutting force and cutting heat can be precisely controlled, so it is to obtain the highest accuracy in precision machining technology of machining method.
The precision servo parts in aircraft hydraulic or pneumatic fittings, dynamic pressure gyro motor bearing parts are using this method processing, in order to reach zero.
1 or 0.
Micron precision and 0 01.
The microscopic roughness 005 microns.
(3) fine milling: used for processing complicated shape of aluminum or beryllium alloy structure.
Depending on the machine tool guideway and the precision of the spindle to obtain high position accuracy.
Use after careful grinding of diamond segment for high speed milling can obtain precise mirror.
(4) fine grinding: used for machining shaft or hole parts.
This kind of parts most use hardened steel, has a high hardness.
Most high precision grinding machine spindle using static or dynamic pressure liquid bearings, to ensure high stability.
In addition to the limit of the grinding precision is affected by spindle and lathe bed stiffness, and the choice of grinding wheel and balance, the machining precision of workpiece center hole, and other factors.
Fine grinding can be obtained 1 micron size precision and 0.
Out of roundness of 5 microns.
In the aerospace industry, precision parts processing is mainly used for processing craft control equipment of precision machinery parts
, such as hydraulic and pneumatic servo precision of matching, the framework of gyroscope, shell, air flotation, fluid bearing components and float, etc.
Small craft precision parts of complex structure, stiffness, require high precision, and larger proportion of difficult-to-machine materials.
We are a performance driven culture that uses SERVICE to ensure continuous improvement.
If you already use SERVICE elsewhere or want the ability to offer restricted chat access to certain individuals, SERVICE mechanical parts manufacturer offers you the most flexibility.
There's the area of manufacturing SERVICE that's becoming very important. If you can create those things, you build this closed bond.
Based on the SERVICE, here are the top compliance challenges businesses face, and what you can do to make them easier on ourselves.
These mechanical parts manufacturer SERVICE have made the life easier. The best feature of the is its mechanical parts manufacturer.
