PROCESSING STEEL

Our objective is to be your problem solver for all things to do with steel. We offer services for all areas of business from the classic steel trader who supplies you with raw material cut to size, through to producing mechanically and thermally processed components on your behalf in our factory. In doing so, we make use of our machinery consisting of ultra-modern sawing machines, conventional lathes and drilling benches as well as centre hole drilling fixtures. For further processes such as deep hole drilling, peeling and heat treatment we work closely with partner companies who are experts in their field.

 

SAWING

Sawing of engineering steel

We are able to produce individual items, small batch series and mass produce components within a very short period of time on more than 20 ultra-modern sawing machines. And we do not just limit ourselves to the numerous round, flat and square section steels we hold in stock, we are also happy to take on sub-contract sawing work on your behalf. Moreover, on request we produce special flat and square sections made from round steel.

  • Round steel bars up to a diameter of 1,000 mm
  • Flat and square section edge lengths up to 1,000 mm
  • Piece weights up to 20 t
  • Rod lengths up to 14 m
  •  

 

DRILLING

Bohren von Edelbaustahl

We are able to centrically drill sawn, pre-cut parts with internal diameters ranging from 22.5-300 mm on 3 drilling benches. And it goes without saying that also includes sub-contract work. Because changing tools only takes a few minutes, we are even able to produce single items and small batch series quickly and economically. An overview of drill diameters and maximum piece lengths is available in our Drilling list.

  • Internal diameters from 22.5-300 mm
  • External diameters up to 950 mm
  • Piece lengths up to 690 mm
  • Piece weights up to 1.7 t
  •  

 

TURNING/FACING

Steel bars on the lathe

We wish to support you during your first processing steps by utilizing our conventional lathes. That is why we focus on rough turning along the entire rod length, contour turning according to drawing specifications and face turning of larger diameters.

  • Rod material up to a diameter of 520 mm
  • Rod lengths up to 7.5 m and piece weights up to 8 t
  • Single pieces up to a diameter of 770 mm on request
  • Machining accuracy of external diameter: -0/+1 mm
  •  

 

CENTRE HOLE DRILLING

Centering a bar of engineering steel

A variety of centring fixtures enable us to drill centre holes in one or both sides of sawn parts. That means you can place the raw material you source from us straight onto your machine without wasting valuable time!

  • DIN 332 type D – centre holes with internal thread M5-M36
  • DIN 332 type B – centre holes of all in all common sizes without thread
  • With or without countersinking

 

HEAT TREATMENT

The right heat treatment gives the steel the properties you require. For example, it is not only possible to alter the mechanical properties such as tensile strength, yield point, impact energy and surface hardness, but also the grain structure and improve machinability. This is achieved through processes such as quenching and tempering, hardening, tempering, soft annealing, normal annealing, normalizing, stress-relief annealing and hot straightening.

Depending on the grade, the steels we hold in stock have already undergone different heat treatment processes at the production site. If you need to satisfy more stringent requirements, we work closely with specialist heat treatment and hardening shops to enable us to offer you the entire spectrum of heat treatment processes. If you need a certain material with specific mechanical properties on a recurring basis, it goes without saying that we will procure it directly from the factory according to your specifications and store it on your behalf. That saves time and costs!

 

DEEP HOLE DRILLING

We are able to process piece lengths up to a maximum of 690 mm on our 3 drilling benches. To be able to offer you further drilling services, we work closely with companies that specialize in drilling deep holes in steel. Their spectrum of performance includes drilling centric and eccentric holes as well as blind holes. Internal diameters begin at 18 mm and end at 850 mm. Holes can be drilled in all of our products – in other words, on external diameters up to 1,000 mm, piece weights up to 20 t and rod lengths up to 14 m. Where required, tight tolerances and surface specifications are achieved by subsequently honing the material. Talk with us!

PEELING

The vast majority of our rolled materials and dimensions have a black surface in accordance with DIN EN 10060. If you require material with tighter tolerances or a special dimension that is not in stock, we are able to supply you with bright steels to DIN EN 10278. To that end, the material we hold in stock is peeled, polished, ground and/or chamfered at a variety of partner companies. To enable you to draw the material and satisfy recurring demand at short notice, we would be happy to source bright steels directly from the factory and hold them in stock on your behalf.
