Case studies

Precision parts in practice

Real delivered projects — process, materials and the machining challenges we solved.

CNC 5-axis — Automation equipment

CNC 5-axis

Material
AL6061-T6
Precision
0.005 mm
Industry
Automation equipment

Complex curved overhanging structure prone to chatter, causing surface tool marks and dimensional drift; multi-directional angled holes beyond 3-axis capability make 5-axis machining a must; thin-wall sections deform easily, calling for optimized fixtures and cutting parameters.

CNC 5-axis — Pneumatic & hydraulic equipment

Corners of the deep U-shaped cavity are hard to clear and retain tool corner radii, affecting assembly; the large circular bottom flange warps from stress under heavy milling, requiring optimized fixtures and layered cutting to release stress; hole groups on different planes demand tight position tolerances and — in turn — precise fixture location and excellent machine repeatability.

CNC turning — Automation drive spindles

CNC turning

Material
42CrMo
Precision
0.005 mm
Industry
Automation drive spindles

Multi-step long shafts deform easily during heat treatment and are hard to straighten; cylindrical grinding must keep the whole shaft coaxial — even slight bending causes excessive runout.
