Threaded bolt

brassknurled

Overview
Turning services using NC/CNC lathes, manual lathes and mill-turn (multi-task) machines. Production of pins, flanges, shafts, rollers and similar turned parts from single prototypes to small series. Knurling (straight/diamond) supported. Integrated handling of material procurement, machining, surface treatment and inspection is available.

Supported machining processes

• Milling / machining center
• Turning (NC/CNC lathes, manual lathes, mill-turn / multitask machines)
• Sheet metal / laser / welding
• Fabrication / welding work
• Wire EDM / EDM
• Plastic / resin machining
• Large-size / long-part machining
• Hardening (heat treatment) / grinding
• Other (various surface treatments, special processes)
