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.
