Engineering Obstacles & Our Solutions

Common Machining Pain Points for This Material

This material has inherent physical defects in precision machining. First, it is prone to tool wear and edge chipping during high-speed cutting, resulting in irregular tool marks on the workpiece surface. Second, the material has slight thermal deformation under continuous cutting heat, leading to dimensional tolerance deviation. Third, the surface finish is difficult to control stably, and it is easy to produce burrs and ripples, which cannot meet the high-standard assembly and use requirements of precision equipment.

Dawnmill Targeted Machining Solutions

Dawnmill adopts exclusive customized processing technology for the inherent defects of the material. We match professional high-wear-resistant cutting tools and optimize layered cutting parameters to avoid edge chipping and reduce tool mark fluctuations. Adopt segmented cooling and constant-temperature processing technology to effectively control processing thermal deformation and lock dimensional stability. Equipped with secondary finish trimming and deburring precision processes to eliminate surface ripples and burrs stably, ensuring consistent surface roughness and meeting high-precision industrial assembly standards.
