Capabilities · DWG NO. BP-WEB-002

Swiss turning. 5-axis milling. Finishing under one roof.

The full capability sheet — what we run, what we hold, and how your parts get finished, inspected and packed without a second supplier.

03 · Surface finishing

One PO covers the finish too

Finishing is where most CNC orders quietly pick up a second supplier, a second shipment and a week of delay. Ours is downstream of the machines, on the same floor.
