Processing characteristics and advantages

All screw element materials are checked by metal analyzer to ensure the quality of raw materials;
100% of the internal splines are checked by spline plug gauge to ensure the interchangeability of screw elements;
All screw elements are finished by CNC grinding after heating, the shape error is controlled within ±0.015, the kneading block sheet spacing and sheet thickness tolerance are controlled within ±0.03, the length tolerance is controlled within ±0.01, and the surface roughness of the outer shape is ≤Ra0.8, completely eliminating the influence of heat treatment deformation on component quality;
Using European HIP process to produce powder high speed steel, and strictly following the customer’s heat treatment process.
