Why we focus exclusively on aluminum
A dedicated aluminum facility lets us optimize cutting parameters, chip evacuation, and thermal management around the material. This focus helps control internal stress in large pockets, reduce distortion in thin-wall geometries, and maintain dimensional accuracy during anodizing preparation.
Stable machining parameters
Aluminum-specific tooling, speeds, feeds, and chip evacuation practices support repeatable production.
Deformation control
Workholding and process planning are adapted for thin walls, deep pockets, and stress-sensitive designs.
Finishing readiness
Parts are prepared with dimensional stability and surface requirements in mind before anodizing or other finishes.
Global project support
Technical review, documentation, and production support for international equipment and technology teams.
Material advantage
2011 aluminum for efficient turned components
2011 aluminum alloy is renowned for exceptional machinability. Its reliable chip-breaking behavior makes it a strong choice for high-speed turning, intricate external threads, and recurring production of small-diameter parts.
01
Reduced cycle times
Excellent cutting performance supports higher throughput in repeated turning operations.
02
Clean surface finish
The alloy can produce a smooth, high-quality finish directly off the machine.
03
Reliable chip control
Effective chip breaking helps prevent nesting and supports consistent tool life.
04
Small-part precision
Suitable for tight-tolerance shafts, connectors, threaded parts, and automatic lathe components.
Production platform
Manufacturing capabilities
From simple plates to complex 5-axis geometries, our production floor supports milling, turning, and turn-mill work across a broad aluminum alloy range.
