What kind of requirements do we have in the production techn

The related application of NC milling cutter head has been more and more widely, so what are the requirements of the NC milling cutter head in production technology? Next, our staff will give you a brief explanation.

 

The hardness of non-cutting part of NC milling cutter head should be 40-45HRC, and the hardness of cutting part should be 63-67HRC. There should be no decarbonization layer and insufficient hardness in the cutting part.

 

For the welded NC milling cutter head, no pore and water penetration are allowed at the welding site. After welding, the blank used as NC milling cutter head should be annealed, fracture and distortion tests should be carried out, and the steel used as cutting part should be metallographically analyzed to determine whether its microstructure is the same as that of standard high-quality steel.

 

The deviation of tool top distance W should not exceed 0.008mm. The radial pendulum difference between the cutting edges of the outer and inner cutting blades on the center line of the NC milling cutter head should not exceed 0.008mm.

 

The back surface of the blade shovel shall ensure that the back angle of the blade section shall be the same in any section passing through the center line of the cutter body of the milling cutter head.
