How to Judge the Processing Quality of a Precision Mechanical Part?

Aug. 10, 2020

As a CNC Pressure Die Casting Services Supplier, we must clearly determine the location. The parts we processed must not only conform to the drawings, but also participate in the assembly work. Therefore, before processing, we need to communicate with customers what parts are involved in assembly. If the tolerance design is unreasonable, we also need to communicate with customers on time.

Generally speaking, mechanical parts are related basic accessories of mechanical equipment, and the complete performance of mechanical equipment can be improved after assembly. Therefore, certain standards are given for parts specifications and dimensional accuracy, and only high-quality products can be guaranteed on the basis of ensuring high precision in the processing of precision parts.

Machining accuracy refers to the relevant accuracy standards proposed for the size, size and shape of the parts in the machining of mechanical parts. During the machining process, it is necessary to constantly compare the actual parts with the design requirements of the drawings. The smaller the error range between the two, the higher the machining accuracy of the precision parts.

Conversely, the larger the difference relative to the design drawing, the lower the machining accuracy of the mechanical parts. In this case, the quality of the parts produced cannot meet the relevant technical requirements of the drawings. They are non-standard parts. Such parts are strictly forbidden to be shipped to customers, so as not to participate in the assembly and affect the overall assembly of the equipment.

For the processing technology, it is mainly through the power to drive the mechanical operation to carry out the processing operation. If this external force condition becomes unstable, it will often directly affect the processing of the parts, resulting in changes in the shape and structure of the processed parts.

The centralization standard of CNC machining means that every process contains as much production and processing content as possible, thereby reducing the number of processes. The CNC machining centralization standard is applicable to the production and processing of product workpieces on high-efficiency professional equipment and CNC lathes. The advantages of choosing the standard of process centralization are: increase productivity; reduce the number of process processes, reduce process lines, simplify production planning and production and manufacturing grassroots party building work; reduce the basic total number, total number of operators and land occupation; reduce product workpiece clamping The frequency not only ensures the precision of the mutual parts between the production and processing surfaces, but also reduces the total number of fixtures and the auxiliary time for clamping the product workpiece. However, CNC processing machinery and equipment and industrial production weapons and equipment projects have a large investment, adjustment and maintenance are relatively inconvenient, and the production site management cycle time is long, which is unfavorable for production adjustment.
