Technology mix in perfection –
just one of our strengths

With more than 160 CNC processing machines we primarily manufacture midsize series up to fully automated large scales with daily volumes of more than 25.000 pieces.

Our particular strengths are complex turning-, drilling- and milling operations of all kinds of metallic materials with narrow tolerances up to the IT6 range. We manufacture our components in several value added stages with appropriate deburring (i.a. ECM).

In order to be able to offer our customers ready-to-install components, we have specialized in the pre-assembly and final assembly of medium complex assembly units more than 10 years ago. The associated processes are carried out by our handling- and automation department.

Since the cleanliness of our products plays an increasingly important role for our customers, we have also focused on provision and conformity with strict residual dirt specifications. We therefore, among other things, have the most advanced washing technology (also with high pressure) and appropriate equipment to determine residual dirt.

Our technologies used for your products

Turning & Milling

Materials:
  • free-cutting steels, case-hardening steels, tempering steels, high-grade stainless steels, light metal alloys, powder metal materials

Primary materials:
  • bar material, saw cuts, cold and hot forged parts, prototype parts, profiled materials, prehardened steels up to 42 HRC

Geometries:
  • Turning from diameter 6 mm to 200 mm (vertically and horizontally), Tipp lengths up to about 200 mm
  • CNC-lathes from single spindle to multispindle technology
  • Milling of cubic parts up to about 200mm x 200 x 200 mm
  • CNC-milling machines with 3 - 5 axes

Accuracies:
  • IT6 for length dimensions and diameters
  • Shape- and positional tolerances up to 10µm
  • Shape- and turning parts partially up to 5µm

Piece weights:
  • 2g – 12,0 kg

















Deep hole drilling

Materials:
  • Free-cutting steels, tempering steels, light metals

Geometries:
  • Clamping diameter 10 – 30 mm
  • Bore diameter 3 – 10 mm
  • Drilling depth up to 350 mm

Accuracies:
  • Concentricity accuracies from 0,05 – 0,1 mm/100 length/li>




Grinding

Grinding processes:
  • Cylindrical-, excentric-, polygon and profile grinding

Geometries:
  • Diameter up to a maximum of 200 mm
  • Length up to a maximum of 500 mm

Accuracies:
  • Diameter IT5
  • RZ-value up to 2 µm



Deburring

Processes:
  • Electrochemical deburring (ECM)
  • Pulse-ECM
  • High-pressure deburring (HD)
  • Barrel finishing
  • Thermal deburring (TEM)
  • Integrated in the manufacturing process: brushing, high-pressure rinsing

Cleaning

Processes:
  • Aqueous immersion bath systems with multilevel ultrasonic- and flood washing
  • Aqueous chamber washing systems with ultrasonic washing and pressure flooding
  • High-pressure washing systems (up to 700 bar)

Cleanliness requirements:
  • Particle size: ≤ 200µm
  • Residual dirt ≤ 0,5 mg / piece
  • High-pressure washing systems (up to 700 bar)

At our plant for the residual dirt analysis the evaluation of technical cleanliness is done by particle size (pattern perception) and particle weight (weigh out), according to VDA19.











Assembly

We offer services in the fields of pre- and final assembly and we are willing to work with you to develop new and individual solutions for your systems:
  • Process-reliable linking of the assembly steps
  • Screwing including securing by glueing e.g. axial diagonal needle bearings for the mechanical- and plant engineering
  • Assembly of axial bearings with automated axial clearance testing for the automobile industry
  • Force-stroke controlled press-in operation of e.g. bearing races
  • Automatic greasing with batchers

In addition, we have gained experience in leak testing of mounted assembly units as well as in attaching of all types of required product marking (needle stamping, laser marking) including the according data systems in order to assure the retraceability of products.
