Tooling for gear production

In our production facilities, we specialize in:

Broaching - internal spline production

We offer the broaching operation either on semi-finished components supplied by the customer, or we deliver completely machined parts including material.

Machine park – horizontal and vertical broaching machines:

  • LAPOINTE 

  • Karl Klink

  • Khemka 

  • 7B55 

Pulling force of broaching machines 10 – 15t
Max. possible length of broaching tools 2000 mm.

Broach tool re-sharpening

We offer professional and high-quality:
Re-sharpening of the broach tooling with a round profile up to a diameter of 150 mm, max.broach tool length 2000 mm.

Sharpening of keyway broaches up to a width of 60 mm, max. broach tool length 2000 mm.

Machine park – Broach tool resharpening machines:

  • Arthur Klink RSH 2000

  • Cincinnati 2000

  • Cincinnati 1500

  • Cincinnati 1000

  • Oswald Forst SM1500

  • Cincinnati 22BS

In cooperation with our proven and high-quality suppliers, we offer:

New broaching tools

High quality, long life pull and push type broaching tools with for the production of internal and external broaching for the following profiles:

  • single-spline and multi-spline profiles
  • involute spline
  • serration spline
  • keyway tools
  • square, hexagonal and polygonal profiles
  • calibration tools
  • polygon shape profile
  • spiral design broaches
  • special Full Form profiles

We have a very skilled design department able to design the tooling according to the needs of the customer and his machine park so that the spline production is as economical as possible (minimum number of tool passes) and at the same time the life of the tool is as long as possible.

We have been using these tools for years not only for our own production, but also supplying them repeatedly to many other engineering companies engaged in the production of parts for the automotive, aerospace and other industries in the EU.

We repeatedly supply these tools to many engineering companies engaged in the production of parts for the automotive, aerospace and other industries in the EU.

The production and inspection of all the above tools are carried out on the most modern specialized CNC machines. For the production of tools, material from specialized manufacturers from Austria and France is used. The heat treatment process of the tools is fully under the control of the manufacturer in its own hardening plant. The tools are coated in Oerlikon Balzers Coating.
If interested, we also offer a complete service including sharpening and coating.
