Manufacturing capabilities
One machining partner for complex component requirements
Our versatile facility combines CNC turning and CNC milling to manage cylindrical parts, non-cylindrical components, complex geometries, and tight tolerances.
01
CNC Turning
Ideal for components where dimensional accuracy is critical. We process aluminum, stainless steel, carbon steel, brass, copper, and engineering plastics.
- Common parts: Structural spacers, sleeves, bushings, pins, shafts, and collars.
- Features: Precision OD/ID, stepped profiles, grooves, chamfers, and threading.
- Tolerances: Strictly adhered to according to your engineering drawings.
02
CNC Milling
Our milling department handles non-cylindrical components and complex features that require multi-axis machining.
- Common parts: Brackets, mounting blocks, and custom structural components.
- Features: Pockets, slots, complex profiles, counterbores, and precision holes.
- Production scale: Single prototypes through repeat production runs.
