Our main customers come from the fields of hydraulic and pneumatic industry, machinery and tool manufacturing, plant engineering and the automotive industry.

Turned parts up to 65mm in diameter we finished off the rack, larger parts up to 250mm as feed rotary part. Our modern machinery enables us to accurately and inexpensive to manufacture. The quality assurance is an important part of our company. This includes, among other things, the certification according to the new DIN EN ISO 9001:2000, which was completed in early January 2003.

Quality and precision:

We manufacture all machinable materials and the latest CNC controlled machines, high-quality precision parts, from single parts to large series.

Machining from bar complete with production of key areas by power-driven tools.

Complete machining on modern multi-axis CNC lathes and machining centers. Finishes: All rework, as well as surface and heat treatments

Chuck work up to a diameter of 250mm rotary parts of the rod: from 6mm to 65mm diameter and 500mm length

Here it's all about top quality ...

Quality means not only to achieve consistent quality standards, but to constantly develop new quality projections for our customers for us.
That is why we always strive to keep our manufacturing and quality assurance at the cutting edge of technology.

Our modern machinery with predominantly multi-axis CNC lathes, as well as highly trained staff allows us to manufacture high quality and sophisticated products to customer specifications.With years of experience and know-how
We want to convince you as a customer and sustainable.
If you want to produce quality, it must also be able to check. For this purpose, we use other than the conventional measuring and test equipment and computer-aided contourograph to measure complex outer and inner contours exactly can.

We are About our cooperation partners able all rework, and to carry out surface and heat treatments.
Thus, Our products meet a ready to assemble for our customers.

We finished on the star machinery Long and small turned parts up to diam. 20.0 and a length up to 200 mm. For shaft-like parts greater lengths are possible through follow-up. The machines are equipped with 5 axes, 15 degree indexing, 3 piece cross-powered tools, sub-spindle, rear-face machining and bar feeder.

On the Gildemeister GLD25L be long and small turned parts up to diam. 25 and length produced about 70 mm. Equipped with 3 driven tools cross, 2 driven tools front of the turret, spindle synchronous, 3 backworking courts and bar feeder FMB Turbo 3-26.

The index GE-65 is a simple, but very accurate 3-axis Universal lathe, with the bar turned parts up to diam. 60 mm and rotational parts to diam. 150 mm are produced. Simple cross drilling and milling operations as well as polygonal milling are easily possible in one setting.

The production possibilities of Colchester Tornado T8M largely correspond to those of the Index GE65, but the driving power of the main spindle and driven tools are higher.(22KW / 3.7 KW)

In the Colchester Tornado 80 is a simple 2-axis Unversaldrehmaschine for bar and chuck work. Bar turned parts dis diam. 42.0 mm can be incorporated easily prepared and efficient.

The SENY thread rolling machine is suitable for rolling M4 - approx M16 at a maximum thread length of about 58mm.

Can handle virtually all machinable materials, in particular, we have a wealth of experience in hard machinable material such as 1.4301, 1.4401, 1.4404, 1.4571, valve steels, quenched and tempered steels (42CrMoS4V), special brass, copper ..... Benefit in particular here of the experience values stored in thousands of CNC programs!

CNC programs are edited and archived by writing an own DNC system. What part of whatever you order, with security is a program of a similar part in our archive, which is then called, slightly modified and saved under a new name.This method reduces the setup costs considerably!

Continue processing methods such as thermal treatment, centerless grinding, surface treatment, assembly can be taken by working with highly competent partners with us.
