Optics
Precision-milled aluminium housings and mounts for optical measurement systems.
CNC milling for complex engineered parts
We procure both simple and complex CNC-milled parts through our qualified manufacturing network. Because we're not tied to our own machine fleet, we select the technically and economically right manufacturing partner for each part — from classic 3-axis components to demanding 5-axis parts with complex contours, free-form surfaces, undercuts, or multiple machining sides.
ISO 9001 certified by TÜV
Typical requirements
- Prototypes, single parts, and small to medium series
- Small precision parts through to larger machine-building components
- Tight form, position, and dimensional tolerances, depending on geometry and material
- Complete further processing — e.g. anodizing, hardening, grinding, coating, or laser marking
- On request: inspection reports, material certificates, and first article inspection reports
Tolerances & quantities
We don't promise blanket extreme values for tolerances and part sizes — the values actually achievable depend on material, geometry, dimensions, manufacturing process, measuring method, and quantity.

Frequently Asked Questions
What is CNC milling?
CNC milling is a machining process in which a computer-controlled rotating tool removes material from a workpiece to create the desired shape. The CNC system enables highly precise, repeatable machining — from simple flat surfaces to complex three-dimensional free-form shapes.
What's the difference between 3-axis and 5-axis milling?
In 3-axis milling, the tool moves along three linear axes (X, Y, Z) — sufficient for many standard geometries. In 5-axis milling, two additional rotational axes are added, allowing parts with complex contours, undercuts, or multiple machined sides to be produced in a single setup — reducing repositioning and improving precision.
What materials can be milled?
In principle, most industrially common materials can be milled — from aluminium and steel alloys to stainless steel, non-ferrous metals, technical plastics, and special materials such as hard metals or ceramics. Which material suits your part depends on the mechanical requirements, the operating environment, and the desired surface quality.
From what quantity does CNC milling make sense?
CNC milling suits single parts and prototypes as well as series production — unlike tool-bound processes, there's no economic minimum quantity, since no costly tooling or molds are required. At J&K, we handle inquiries starting from quantity 1, with particular strength in small and medium series.
What does CNC milling cost?
Cost depends on several factors: part geometry, material, tolerance requirements, machining time, quantity, and any further processing required. A blanket price per part therefore can't be stated responsibly. 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. Our digital quoting system GP-Digit enables fast quote processing — you send us your drawing data and any further relevant inquiry details, ideally via the request form on our website or by e-mail (info@jk-cnc-technik.de), and receive a feasibility assessment and a firm, binding quote by 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, our role spans the entire process: from manufacturing-oriented consulting through to the on-time delivery of high-quality engineered parts.
