Step 01
Sawing
The bar is cut to blank length, with an allowance for chucking. The heat number of the material is recorded here, and from this point the part can be traced back to its certificate.
Dual-column bandsaw. Capacity up to Ø560 mm*.

Step 02
Roughing
The bulk of the material comes off, leaving an allowance for finishing. What matters here is metal removal rate, not accuracy: the shape approaches the dimension without yet reaching it.
Longitudinal turning, with a finishing allowance.

Step 03
Finishing
The diameters reach size; shoulders, grooves and chamfers appear. From here on, every pass changes a value written on your drawing.

Step 04
Five-axis milling
The trunnion table tilts the part under the tool, reaching faces a three-axis machine never sees. Flats, bore and bolt circle come out of a single setup, with no repositioning error between them.

Step 05
Grinding
The bearing journal is ground after stress relief, not before: the material redistributes its stresses when heated, and a dimension held before that does not stay where it was put.
Surface grinding, 500 × 1,000 mm*. In-house stress relief beforehand.

Step 06
3D measurement
The first article is measured in full, and the series is checked on the critical dimensions. The dimensional report travels with the batch, alongside the material certificate.

The part, after all six operations
The same shaft, drawn at the end of the road. Pick an operation and the features it produced light up — the rest stay dim. That is how you see what the finished drawing owes to each pass through the shop.
Operation
- What it produces
Schematic representation. The dimensions are those of the simulation’s reference drawing, not of an ordered part.
How to read the drawing
The dash-dot line down the middle is the axis of rotation: the part is symmetrical about it, so it is drawn once and understood whole. Dimensions marked Ø are diameters, not radii — a confusion that costs half the material. The dim outline behind is the bar it started from.
The same profile as the simulation
This geometry is not drawn separately: it is the same list of coordinates that drives the roughing simulation above. Two drawings of one part, made from different data, would contradict each other at the first change.

What we can machine
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.
Quality you can read, not just hear about
Every batch leaves the shop with a material certificate and a dimensional report. Every part traces back to the heat number of its stock.
Batch traceability
Every part can be traced back to the heat number of its material.
First article inspection
FAI per AS9102, before the series is released.
Dimensional reports
