Our services

Raw materials

We use bar-form or hot-moulded raw materials, and create structural steels, in particular hardening steel, case-hardening steel, induction tempering steel and nitriding steel.

Surface treatments

The treatments most commonly used in our production processes include galvanisation, phosphating, nickel, chrome and molybdenum plating, Molykote coating and painting.

Heat treatments

In-house application of induction tempering treatments, and out-sourced hardening, nitriding, carbon-nitriding and case-hardening.

Machining

In-house machining processes include cutting, drilling, turning, milling and centreless grinding. Additionally, the turning of small parts, toothing, deep drilling, centred grinding and welding is outsourced.

Components for assembly

Procurement from specialised suppliers of laser sliced or cut parts to be assembled and/or welded onto components machined in-house.

Abroad

Our company supplies more than 30% of its products to over 20 foreign countries, including Germany, England, Belgium, France, Austria, Spain, Poland, Hungary, Turkey, Croatia, the United States, Canada, Mexico, Argentina, Brazil, India and China.

Our products

  • Rail shafts
  • Planetary Pinions
  • Shafts
  • Small welded components
  • Forged items and Spacers
  • Forks

These are made from C45/42CrMo4 (tempering steel) using the induction tempering treatment. Production ranges in diameter from Ø 10 to Ø 35 and in length from 80 mm to 700 mm.

These are made from 16 Mncr5/18NiCrMo5 (case-hardening steel) with the case-hardening tempering or nitriding process. Production ranges in diameter from Ø 14 to Ø 80 and in length from 40 mm to 400 mm.

Shafts are made with tempering, hardening or case-hardening steels. In the case of drive shafts, the gear toothing is carried out by a specialised supplier. Components are subjected to case-hardening tempering or induction tempering. Production ranges in diameter from Ø 20 to Ø 100 and in length from 100 mm to 700 mm.

Our small welded components are made in C40 hardening steel and sheered with structural steel. Production ranges in diameter from Ø 10 to Ø 35 and in length from 80 mm to 500 mm.

Forged items and spacers are made from structural, tempering or hardening steel. Production ranges in diameter from Ø 20 to Ø 150 and in length from 40 mm to 400 mm.

Made from induction-tempered structural steel.

Our production departments

Cutting

Il The cutting of materials in bars is carried out with the use of cutting machines, transfer cutting machines and turning machines with diameters ranging from Ø 6 to Ø 80 and lengths from 30 mm to 2000 mm.

Turning

The company has a bar turning department composed of both sliding- and fixed-head lathes for machining shafts of a diameter of between Ø 10 and Ø 60 and a length of between 50 mm and 1000 mm, as well as a secondary turning department for the machining of forged items or sections up to a diameter of Ø 150 and a length of 300 mm.

Milling

Milling and drilling of components is carried out on vertical machining centres, transfer machines and numerical control grinding machines.

Induction tempering

High- and medium-frequency induction tempering is carried out in-house with the use of systems ranging from 35 to 100 kw on items with a diameter of between Ø 8 and Ø 80 and with a maximum length of 1 m.

Grinding

Generally, our parts are finished via the process of outside diameter grinding with the use of manual and/or automatic-loading centreless grinders.

Tooling

The tooling department allows for the in-house creation of tools to support general production, as well as the creation of prototypes and small runs and pre-runs of new components.

Warehouse, logistics and shipping

This department includes the raw-materials, semi-finished and finished product warehouse, and the washing, assembly, protection, packing and shipping of products.

Quality control

The quality control department includes a laboratory certified for the carrying out of dimensional, surface and metal controls on the products created.
