Turned mounts and adapters for holding optical components.
CNC turning for rotationally symmetric precision parts
In CNC turning, we procure classic turned parts as well as complex mill-turn parts through our qualified manufacturing network. These include shafts, bushings, sleeves, bolts, flanges, rings, and rotationally symmetric precision parts with cross holes, milled faces, or demanding internal contours.
ISO 9001 certified by TÜV
Our focus
- Prototypes and small, medium, and recurring series
- Long and short turned parts
- Complex mill-turn parts in a single setup
- Tight diameter, concentricity, and coaxiality tolerances
- Ready-to-install delivery incl. surface treatment, heat treatment, and quality documentation
Tolerances & quantities
Achievable diameter, runout and coaxiality tolerances depend on material, geometry, dimensions and process — we deliberately don't promise blanket extreme values.

Frequently Asked Questions
What is CNC turning?
CNC turning is a machining process in which the workpiece rotates and a computer-controlled tool removes material. It's especially suited to rotationally symmetric parts like shafts, bushings, and flanges — with high dimensional and concentricity accuracy.
What's the difference between turning and milling?
In turning, the workpiece rotates and the tool is stationary — ideal for rotationally symmetric shapes. In milling, the tool rotates and the workpiece is fixed — ideal for prismatic parts and complex surfaces. Mill-turn machining combines both in a single setup.
What are mill-turn parts?
Mill-turn parts are both turned and milled in a single setup. This allows rotationally symmetric base shapes with additional milled faces, cross holes, or grooves — without repositioning, which improves accuracy and efficiency.
What parts can be turned?
Typical turned parts are shafts, bushings, sleeves, bolts, flanges, rings, and spacers. Mill-turn machining adds more complex geometries with cross holes, milled faces, and internal contours.
What does CNC turning cost?
Cost depends on geometry, material, tolerances, machining time, and quantity. Through our digital quoting system GP-Digit, based on your drawing, you'll typically receive a firm, binding quote within 24 hours.
How fast do I receive a quote?
Typically within 24 hours. Through our digital quoting system GP-Digit you send us your drawing data — via the request form or e-mail (info@jk-cnc-technik.de) — and receive a binding quote the next business day.
Do you manufacture in-house or through partners?
We orchestrate a network of carefully selected, highly specialized manufacturing partners in Germany and internationally. As your central procurement partner, we accompany the entire process from consulting to on-time delivery.
