Our production capacity consists of

Capacity is not just a machine count. What matters is having the right machine type for each part, enough of them to absorb a volume increase, and the inspection equipment to prove the result.

How the machines are used

Matching the part to the process

CNC sliding head lathes — 50 machines

Swiss-type automatics support the bar close to the cutting point, which is what makes long, slender parts possible at all. With driven tools, back-working spindles and bar feeders they produce a complete component in one cycle and run unattended overnight.

CNC turret turning machines — 20 machines

Turret centres take over where diameter, wall thickness or milling content exceed what a sliding head can carry. They handle both bar and cast blanks up to Ø 52 mm.

Super-precision hard turning — 3 machines

Some parts have to be hardened before their final dimensions are cut. Hard turning replaces a grinding operation, removing a process step, a supplier and a transport leg.

Hydromat rotary transfer — 2 machines

Rotary transfer machines carry the part through many stations simultaneously. They only make economic sense at very high volume — which is exactly what they are there for.

Washing & inspection

Clean, measured, then packed

Every batch passes through the ultrasonic degreasing and washing plant before final inspection. Hydraulic and automotive customers specify technical cleanliness, and residual chips or oil are as much a defect as a wrong dimension.

Inspection combines contact and non-contact methods. Where a part demands it, we run 100% camera sorting, SPC analysis of measured dimensions and CMM measurement of complex geometries.
