Custom CNC Machining Tolerances and Standards
The concepts of component interchangeability and dimensional tolerances are an accepted part of manufacturing. Unfortunately, misuse of the latter can lead to a host of problems. For example, overly tight tolerances may require a part to undergo a secondary grinding or EDM operation to complete, unnecessarily increasing cost and lead time. Tolerances that are “too loose” or inconsistent with the tolerances of the mating parts can render the assembly impossible, requiring rework or, at worst, making the finished product unusable.

Custom CNC Machining Surface Finishes
You can choose a wide selection of metal surface finishing services after machining at Yangzheng CNC machining manufacturer to improve the parts appearance, surface finishes, corrosion resistance, and other performance of your CNC machined parts.
| Name | Description | Materials | Color | |
![]() |
Anodizing | The aluminum alloy is treated with hard anodic oxidation, and the surface can form a film layer with a thickness of 30-50 μm and a hardness of about 500HV, which has excellent corrosion resistance and wear resistance. | Aluminum | Clear, black, grey, red, blue, gold. |
![]() |
Bead Blasting | Spray the powder coating on the surface of the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating. The surface color is combined with a silky and dry feel, which combines unique aesthetics with high performance of the product. | ABS, Aluminum, Brass, Stainless Steel, Steel | n/a |
![]() |
Powder Coating | Used on some metal workpieces by spraying or fluidized bed, the powder is electrostatically adsorbed on the surface of the workpiece, and when it is completely dry, a protective film will be formed on the surface. | Aluminum, Stainless Steel, Steel,Titanium | Black, any RAL code or Pantone number |
![]() |
Electroplating | The process of attaching a layer of metal film to the surface of parts by electrolysis, so as to prevent metal oxidation, improve wear resistance, conductivity, light reflection, corrosion resistance and improve appearance. The outer layer of many coins is also electroplated. | Aluminum, steel, stainless steel | n/a |
![]() |
Polishing | The whole process of electrolytic polishing is basically completed automatically, so the labor cost is very low. Environmental impact: Electrolytic polishing uses less harmful chemicals. The whole process requires a small amount of water and is easy to operate. Metal parts can achieve the effect of delaying corrosion. | Aluminum, Brass, Stainless Steel, Steel | n/a |
![]() |
Brushing | Make the metal surface obtain a non-mirror-like metallic luster, and at the same time, the brushed treatment can also eliminate the slight flaws on the metal surface.
