Material-We-Used

Our Milling Tolerance Standard

Our CNC milling service offers highly accurate and tightly precise milling. Please note that tolerance is affected by the type of material used along with the geometry of the part that is milled. For more details, consult the GB/T1804-2000(mm) below:

Tolerance LeverOverall Dimension Range
Specifications<<3, >0.5<<6, >3<<30, >6<<120, >30<<400, >120<<1000, >400<<2000, >1000
Tolerance Standard
F±0.05±0.05±0.1±0.15±0.2±0.3±0.5
M±0.1±0.1±0.2±10.3±0.5±0.8±1.2
C±0.2±0.3±0.5±0.8±1.2±2±3
V±0.5±1±1.5±2.5±4±6

In the default state, the products or parts we machine for customers are executed at the F level. In fact, this standard is not sufficient to reflect our strong machining capabilities, as we can control the minimum tolerance to 0.005mm.

Finishing For Milled Parts

When we have milled your part with high degree of accuracy and precision, it is time for surface finish which is aviable in the following options:


As machined (Ra 3.2μm / Ra 126μin)
Smooth machining (Ra 1.6μm / Ra 63μin)
Fine machining (Ra 0.8μm / Ra 32μin)
