High Accuracy Parts Machining

The accuracy of CNC machining of hardware parts can reach a very high level, usually up to a few micrometers(μ m) Even smaller. The following are some common precision requirements for CNC machining of hardware parts:
Dimensional accuracy:
CNC machining can achieve high dimensional accuracy, typically meeting tolerance requirements of ± 0.01mm or less. This means that the dimensions of the processed parts are very close to those on the design drawings.

Surface roughness:
CNC machining can control the surface roughness of parts to meet specific requirements. Ra 0.8 can usually be achieved μ Surface roughness of m or smaller, sometimes even reaching Ra 0.4 μ Below m.

Parallelism and verticality:
CNC machining can ensure the parallelism and verticality of the parts, and ensure that the relationships between the various surfaces of the parts meet the requirements. Usually, it can meet the requirements of parallelism and verticality within 0.02mm.

Aperture accuracy:
CNC machining can achieve high-precision aperture processing, including drilling, reaming, and so on. Usually, the aperture accuracy can reach the H7 level, which means that the aperture is very close to the size required by the design.

It should be noted that the actual accuracy requirements depend on the specific part design and processing requirements. Different materials, shapes, and processing methods may have an impact on accuracy. In addition, factors such as the performance of the machine tool, tool quality, and processing environment also need to be considered.
