Capabilities
We cover the full flow — from sawing and CNC turning or milling to grinding, wire EDM and 3D dimensional inspection. Full simultaneous 5-axis on our Mazak CV5-500.
- 01 CNC turning Ten CNC lathes, mostly Mazak, many with live tooling and a few of those also with a Y-axis. Bar-fed or chucked components up to Ø500 mm.
- 02 CNC milling and 5-axis The Mazak CV5-500 Smooth X machines complex parts in a single setup on five simultaneous axes, up to Ø500 × 320 mm. For prismatic work, the Haas VF-2.
- 03 Grinding and wire EDM Surface grinding across areas up to 500 × 1,000 mm, and wire EDM for complex contours and hardened parts up to 500 mm thick.
- 04 Sawing and material preparation Two dual-column bandsaws cut bar stock and sections up to 560 mm. Stress relieving is done in-house, between roughing and finishing.
- 05 3D measurement and inspection Two coordinate measuring machines — a ZEISS CONTURA and a TESA MICRO-HITE 3D — cover the whole flow: first article, in-process control and the dimensional report that ships with the batch.
Which process, for which part
The five above are a menu. Below is the map: which of them your part needs, and why the order matters.
- A part of revolution — shaft, bushing, flange
- It starts at turning. If it also has off-axis holes, flats or a keyway, the lathes with live tooling do them in the same setup; with a Y-axis, off-axis milling too. Every setup avoided is one positioning error fewer.
- A prismatic part, with faces in several directions
- It goes to milling. On the five-axis centre, angled faces are clamped once: position is not lost between setups and their deviations do not add up. For simple parts with parallel faces, the three-axis centre is cheaper and just as good.
- A hardened part, above roughly 55 HRC
- The shape is cut before heat treatment, with an allowance; final dimensions afterwards, by grinding or wire EDM. The wire also cuts sharp internal corners that no cutter can produce — the cutter radius stays in the corner.
- Every part, at the start and at the end
- Everything begins at sawing, and the length ordered is always greater than the one on the drawing: the sawn end is faced off, and the part needs a section to be held by. Measurement accompanies the whole route, not only its end.
One part, from drawing to delivery
An example, not a reference: the shaft drawn above, in a run of 250 pieces from quenched-and-tempered 42CrMo4, with a keyway and a sealing surface. The input figures are chosen for the example; what the table shows is the order, and what each operation leaves for the next.
| Operation | What happens | What it leaves behind |
|---|---|---|
| Sawing | The bar is cut to the ordered length, longer than the one on the drawing. | An allowance to face off the sawn end, and a section for the chuck to hold. |
| Stress relief | The blank is held at temperature and cooled slowly. | The stresses from rolling, released now, no longer move the part between roughing and finishing. |
| Roughing | The bulk of the material comes off, with deep passes and a firm feed. | An even allowance of a few tenths, so that finishing cuts the same everywhere. |
| Finishing | The functional dimensions are turned, with live tooling for the keyway. | The diameter inside the h7 field and the sealing surface at the required finish, in a single setup. |
| Measurement | The first article is measured in full; the rest is sampled on the agreed characteristics. | The first article report before the series, the dimensional protocol with every batch. |
| Delivery | The parts leave with the batch documentation. | A 3.1 material certificate, the dimensional protocol, traceability to the heat number. |
What is deliberately missing from the table: times and price. Those are worked out on your drawing, not on ours — an example that also gave figures would be a quotation for somebody else’s part.
