What we do

End-to-end manufacturing capabilities

From prototype to volume production, all under one roof with in-house quality control.

CNC Milling

3-, 4- and 5-axis milling plus CNC gantry machining for complex geometries and multi-surface parts in one clamping.

CNC Turning

Horizontal and vertical NC lathes, turn-mill compounds and Swiss-type lathes for high-precision turned components.

Grinding

Surface grinding, manual and CNC ID/OD grinding, and gantry grinding for tight-tolerance finishing.

Wire-Cut & EDM

Fast, medium and slow wire-cut EDM plus sinker EDM for hardened materials and intricate profiles.

Surface & Heat Treatment

Nickel/zinc plating, blackening, anodizing and coating; nitriding, carbonitriding, quench and temper.

Secondary Services

Welding, polishing, assembly, casting, forging, stamping, sheet-metal fabrication, powder metallurgy and 3D printing.

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.

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

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.
