How to Control the Surface Roughness of Precision Hardware Processing
With the progress of science and technology and the development of society, people put forward higher and higher requirements for the performance and quality of precision machining products. The performance and quality of products are determined by product design and guaranteed by precision hardware processing, manufacturing and assembly quality, which includes processing accuracy and surface quality. The surface quality of precision mechanical parts is one of the most important indicators, especially for the reliability of parts under high-speed, high temperature and high pressure conditions.
The machined surface is to change the size, shape and performance of the blank surface through precision machining or other methods to make it meet the requirements of the design drawings. However, the cylindrical surface formed by turning of precision mechanical parts is not an ideal surface. After machining, a very thin surface layer is formed on the part surface, and its characteristics are very different from those of the internal matrix. During precision metal processing, the surface is subjected to elastic and plastic deformation under the complex stress state of wedging, extrusion, fracture and friction during the whole cutting process. Under the combined action of cutting force, cutting heat and surrounding media, the original geometric characteristics and physical and mechanical properties of the workpiece surface are changed. Therefore, the "surface quality" is used to evaluate the compliance of the geometric, physical, chemical or other engineering performance of the surface layer of the machined part with the technical requirements of the part. The main contents are as follows.
Surface roughness: the micro geometric shape feature composed of small spacing peaks and valleys on the precision metal processing surface, which is mainly formed by the motion track of cutting tools in precision machining, and the ratio of wave height to wavelength is generally greater than 1:50.

FAQ:
Q: Is your organization committed to the concept of total quality management?
A: Yes, no matter bending, laser cutting or CNC processing, workers will conduct the first sample inspection and random inspection during processing to ensure product quality.
Q: How many inspections should be carried out for a project?
A: Generally, products will undergo the following four inspections: incoming inspection, first production inspection, sampling inspection and pre shipment inspection. Among them, sampling inspection will be conducted many times.
Q: Can you review the drawings with our engineering team and provide a quick and estimated price for the required changes?
A: Yes, our engineers are very quick. If there is anything in the product that needs to be modified, we can give you a new price immediately after you tell us.
