Precision parts processing technology includes the following:
Common surface treatment: blackening, anodizing, chrome plating, nickel plating, titanium plating, galvanizing, electropolishing, passivation, PVD plating, Ganak plating, etc.
Commonly used heat treatment methods: vacuum quenching, tempering, salt bath nitriding treatment, nitriding, carburizing, high frequency wave burning, carbon immersion burning, etc.
The equipment used is:
Production equipment: turning, milling, flat circular grinding, internal and external circular grinding, fast/slow wire running, machining center, EDM and other precision machines.
Testing equipment: height meter, projector, hardness tester, micrometer, etc.
Precision parts processing technology (heat treatment process), determine the machine tool used in each process, clamping method, measurement method, processing allowance, cutting amount and working hour quota. Fill in the process sheet, this is the process of machining procedures.
Precision parts processing dimension requirements:
Cylinder for example: for example, how much is the diameter of the cylinder, there are strict requirements, positive and negative errors within the specified range of requirements are qualified parts, otherwise they are unqualified parts; Such as an embedded cylinder, if the diameter is too large, beyond the allowable range of error, it will cause, can not be inserted into the situation, if the actual diameter is too small, beyond the allowable negative lower limit of error, it will cause too loose, unstable problems occur.
These are unqualified products, or the length of the cylinder is too long or too short, beyond the allowable range of error, are unqualified products, are to be scrapped, or reprocessed, which will inevitably cause an increase in costs.
The second is the advanced non-standard precision parts processing equipment and testing equipment, advanced processing equipment makes the processing of precision parts more simple, higher precision, better effect.
