CNC machining

We mill, turn and bore parts and weldments to the customer's drawing documentation. We focus on one-off and small-batch production on our own machine park — CNC and conventional. CNC machining is carried out at our own production facility in Pardubice–Rosice, Czech Republic, for customers at home and abroad.

Machining is combined with subsequent dimensional inspection.

Production scope

What we machine

We machine individual parts and weldments — typically housings, plates, bushings, rotational parts and clamping elements. We produce anything from a single piece to a small batch, always according to the supplied drawing documentation or STEP model. For each part we assess manufacturability and propose a suitable machine and process.

Machining technologies

CNC milling

Milling, drilling and finishing of parts and weldments on a vertical machining centre.

CNC turning

Rotational parts from steel, stainless steel and aluminium; including large and long pieces.

Horizontal boring

Machining of large and heavy parts on a horizontal boring machine.

Conventional machining

Supplementary turning, milling, drilling and slotting operations.

Materials

We routinely machine structural, tool and alloy steels, stainless steel, aluminium, brass, bronze and plastics. The choice of machine and technology depends on the specific grade, dimensions and geometry of the part.

Machines for machining

In-house machine park

Dimensional capacity depends on the specific machine. The largest rotational parts are turned up to Ø 840 mm and 3 500 mm in length, and large, heavy parts are machined on a horizontal boring machine within 3 500 × 2 000 × 1 250 mm. We use our machine park for custom and small-batch production based on customer documentation.

Integrated production

Machining of weldments and integrated production

Machining here often follows on from our own production of weldments and steel structures. On weldments we machine mounting, seating and functional surfaces, so we can deliver an assembly ready for further assembly or completion. We integrate cutting, forming, welding, machining and assembly within our own production facility.

Quality and inspection

Inspection of finished parts

We measure machined parts and assemblies in our own facility. Depending on the order we carry out in-process and final dimensional inspection, and for large parts also large-scale 3D measurement with the KEYENCE WM-6000 system. Specific tolerances and the inspection method are set according to the drawing documentation and technological capabilities; a measurement report is prepared on request.
