KURT Workholding: Horizontal Machining Center Concepts

The Horizontal Machining Center (HMC) concept favours uninterrupted production work. One reason for this is that the horizontal position encourages chips to fall away, so they don’t have to be cleared from the table. More significantly, the horizontal design allows a two-pallet machine to be incorporated into a space-efficient machine. To save time, work can be loaded on one pallet of a horizontal machining center while machining occurs on the other pallet.

Horizontal Machining Center Applications

There are many benefits associated with horizontal machining, some of which include:

  • Shorter processing time per part – With horizontals’ ability to swap pallets, there is no significant delay between machining cycles for job change-over. Plus, on the tombstone fixtures, various pieces can be completed in a single cycle.
  • Lower prices – Horizontal machining has brought down the overall price per part quoted to customers.
  • Three-side machining – The B axis allows three faces of the part to be reached in one cycle. Parts with similar features can also be machined in the same cycle to ensure accuracy.
  • Complex part machining – Complex parts can now be machined more quickly and cost-effectively than ever before.
  • Advanced tooling platform – Horizontal machining centers take advantage of the latest in cutting tool technology.
  • Multi-customer Response – The ability to run multiple jobs on alternating pallets of the same machine allows use to fill orders for two customers in the same shift.


Depending on the job we offer a variety of diverse types of horizontal workholding to fit all your machining needs.

Horn Thread Cutting Tools from M1 to M2.5

DCG thread milling cutters for M1 to M2.5

Thread Production in hard-to-cut materials

Horn presents new developments in the DCG thread milling system. Suitable for producing threads from M1 to M2.5 (metric ISO threads DIN 13–20), the tools extend the possible applications of the DCG series for the reliable milling of threads. They have extremely sharp cutting edges and are suitable for universal use thanks to their coating. The solid carbide milling cutters are available as standard up to a thread length of 2 x D. They demonstrate their special capabilities and efficiency when machining steels, stainless steels, cast iron, non-ferrous metals and in particular hard-to-cut materials used in the medical technology sector, for example.

DCG solid carbide milling cutters have been proving themselves in the production of threads sized from M3 to M12 for many years. As the single-row milling cutters can be used for different pitches, a high degree of flexibility is guaranteed.

Tooling Solutions for Gear Skiving

For the high-productivity manufacturing of internal gear teeth, splines and other internal profiles, HORN is introducing tools for gear skiving. This machining method has a number of advantages:

  • Considerably shorter processing times in comparison to gear tooth broaching
  • Can be used on optimised milling centres
  • No undercut necessary at the end of the gear tooth
  • Turning and gear cutting possible in a single clamping

Depending on the number of gear teeth and the size of the module, a number of different tool interfaces is used. Each tool is designed specifically for the intended application and adapted for the material. Gear skiving tools are therefore used for medium and large batch sizes. On the tooth flanks, typical surfaces are created which differ from the flanks created by broaching. Depending on the geometry of the component, gear skiving may also be a useful alternative to hobbing or broaching for external gear teeth as well.
