We are a small company that produces individual parts and small series according to customer drawings. Our machine park includes a Weiler CNC lathe, like a Chiron milling machine. Both machines have a tool capacity of 12 tools. We can produce turned parts up to Ø42mm and milled parts of 300x250x150mm. Customer service and quality are very important to us. We have short delivery times and a high level of quality awareness. We look forward to your inquiries.

With over 200 employees, we manufacture at our sites in ice rink, Schönbrunn and Apolda for our customers turned parts from a workpiece diameter of 0.2 mm to 250mm, threaded rods and assemblies on the most modern CNC lathes, machining centers and multi-spindle automatic lathes.
It processes material from 0.5 mm to 65 mm diameter of the rod and 240 mm diameter chuck parts from almost all machinable materials (cutting steels, structural steels, case hardening steels, rust and acid resistant steel, V2A, V4A, titanium, brass, ECOBRASS, aluminum , plastics, and any other machinable materials)

The production scope includes threaded rods to M42 or trapezoidal thread with a pitch to 6 mm up to 6000 mm length, gears (for steel to module 0.8 and brass to Module1).

In separate manufacturing areas, we have created the ability to perform additional operations such as drilling, milling and sawing, bending, punching, pressing, broaching, welding, soldering, thread rolling and thread cutting and assembly work.

Heat treatments and surface finishing are carried out in cooperation with selected expert partners.

Highest standards of quality, reliability and flexibility are the basis to earn and build the trust of our customers.
Through our ISO 9001 certified, process-oriented quality management system, we are to provide top quality consistently able to offer our customers.

In order to give our customers an overview of our extensive range of services, we have listed these here and briefly described:

Ready to install precision parts
Production of simple turned parts, up to 5-axis machined workpieces, as well as ready-to-install long turned parts. For surface coatings and hardening processes we have efficient partners.

Special designs, prototypes, prototyping
Upon request of the customer, we are happy to produce first samples, prototypes and special designs according to samples or drawings.

Air-conditioned measuring room
Zeiss 3D measuring machine, as well as contourograph and roughness measurement.

Precision turned parts, CNC turning parts and screw-cutting from 3 to 40 mm in diameter and up to 500 mm workpiece length, in the categories of standard parts and simple to complex parts in small series or large numbers.
