Wenlio delivers world-class CNC broaching services that combine cutting-edge technology with uncompromising quality standards.
Our advanced machining capabilities can control your components tolerances within 0.02 mm.
Wenlio uses a dual-motor synchronized servo drive system engineered for high-tonnage broaching, delivering stable power output and precise process control. The machine features a dual-bed, opposed layout with the broaching zone positioned at the center, keeping the load path and broaching center in the same plane. This design helps improve rigidity and machining consistency, and supports a wide range of internal and external broaching applications.
Depending on part size and process requirements, stroke and fixturing can be configured accordingly, covering broaching needs from small precision components to large castings and forgings.
