Machine Park

Our machine park covers the full production chain — turning, 3- and 5-axis milling, railway welding and metrology inspection in one place. Hermle (Germany), Kovosvit MAS (Czech Republic), TBI (Poland) and Doosan (Korea) centres — combining European precision with Asian efficiency. Welding compliant with EN 15085-2 CL 2 and EN ISO 3834-2, CMM inspection in a climate-controlled lab, pallet automation and robotic CNC handling. We tailor machining scope to each customer's individual requirements.

▌ 01 / 5-AXIS MILLING

5 5-axis centres — precision in a single setup

Five simultaneous 5-axis centres allow machining of complex geometries without repositioning the part. Our machine configuration combines European finishing precision (Hermle) with heavy-duty machining capability for large castings and welded housings (Kovosvit MAS).

▌ 04 / AUTOMATION

Robotic CNC handling and palletisation

We invest in machine handling automation — the palletiser and robotic exchange stations reduce non-productive time and enable shift work without requiring an operator to be permanently present at every machine.

Palletiser with loading station - pallet changer with glass enclosure, machining centre, automatic CNC handling
AUTOMATION
Palletiser with pallet changer
The palletiser enables automatic loading of parts into the machining centre. It reduces non-productive time and allows machining of longer series without manual part changes by an operator.

FunctionAutomatic CNC loading
Operating modeUnattended / longer series
Machining station cobot - 6-axis cobot with gripper holding a part, servicing a machining centre with open doors
ROBOTISATION
Machining station cobot
A robotic station for loading and unloading parts into CNC machines. Supports series production — the operator supervises the process instead of manually servicing each machine.
