Precision milling

In CNC milling, we manufacture precision milled parts with tolerances up to 0.005 mm and reproducible quality in series production.

In precision milling, we manufacture components around the clock on modern 5-axis machining centres. Fully automated processes ensure high repeatability and stable production runs. Our manufacturing is designed for process stability, efficiency and reproducible quality, making it suitable for demanding series production in medium and large batch sizes.

The most important points

  • CNC milling from block material or cast blanks.
  • Tolerance range: up to 5 µm, depending on material and geometry
  • Dimensions: Working area up to max. 800 × 800 × 550 mm
  • High degree of automation and stable processes

Use of 5-axis machining centres

In CNC milling, we manufacture your components in a highly automated production environment on modern 5-axis machining centres. The combination of simultaneous 5-axis technology and advanced robotic automation enables efficient production, high flexibility and consistently high component quality.

This makes us a reliable partner when it comes to high-precision and economically manufactured milled components for medium and large batch sizes.

Quality assurance and documented test results

Our high-performance measurement technology ensures that every precision milled part meets our requirements for dimensional accuracy and quality – from the first part to the last. From process release to final inspection, we document all measurement results on high-precision Hexagon co-ordinate measuring machines.

We continuously monitor process stability, either directly at the machine or in our climate-controlled measurement technology rooms. This ensures reproducible, documented precision and reliable quality.

Frequently asked questions about precision milling

What is meant by precision milling?
Precision milling is a manufacturing process in which components are produced using high-precision CNC milling machines, suitable tools and controlled process parameters. This results in components with tight dimensional, shape and positional tolerances as well as delicate surfaces.
What tolerances are possible in precision milling?
In precision milling, we manufacture precision milled parts with tolerances from 5 µm, depending on component geometry and material. Our 5-axis machining centres are equipped with high-precision packages and zero-point clamping systems that support maximum process stability and precision.
What component sizes can be manufactured?
In precision milling, we machine components, mostly from block material, within a machining area of up to 800 × 800 × 550 mm.
How do you ensure quality in the series?
We ensure series quality through in-process tests, documented measurement results and continuous monitoring of series production with highly accurate measuring and testing equipment.

Surface technology and surface finishing

Following precision milling, surface finishing can be offered as the next process step, if desired, for the targeted surface treatment of your components. Using a variety of methods, we meet defined requirements for function, protection and appearance, ensuring the operational readiness of your precision-milled parts.
