Precision component processing technology includes the following contents:
Common surface treatment: blackening, anodizing, chromium plating, nickel plating, titanium plating, zinc plating, electropolishing, passivation, PVD film plating, Ganac, etc.
Commonly used heat treatment methods include vacuum quenching, quenching and tempering, salt bath nitriding, nitriding, carburizing, high cycle firing, immersion firing, etc.
The equipment used includes:
Production equipment: precision machines such as turning, milling, flat round grinding, inner and outer round grinding, fast/slow wire walking, machining center, electric spark, etc.
Testing equipment: altimeter, projector, hardness tester, micrometer, etc.
The processing technology of precision components (heat treatment process), determining the machine tool, clamping method, measurement method, machining allowance, cutting amount, and working hour quota used in each process. Fill in various contents on the process specification sheet, which is the specification for mechanical processing technology.
Requirements for machining dimensions of precision parts:
For example, taking a cylinder as an example, there are strict requirements for the diameter of the cylinder. Positive and negative errors within the specified range are qualified parts, otherwise they are all unqualified parts; If the diameter of an embedded cylinder is too large and exceeds the allowable error range, it will cause the problem of not being inserted. If the actual diameter is too small and exceeds the lower limit of the allowable negative error value, it will cause the problem of being inserted too loosely and not firmly.
These are all unqualified products, or the length of the cylinder is too long or too short, which exceeds the allowable error range. They are all unqualified products and must be scrapped or reprocessed, which will inevitably lead to increased costs.
Secondly, advanced non-standard precision parts processing equipment and testing equipment make processing precision parts simpler, more accurate, and more effective.
