Your Solution for Gear Hobbing

Horizontal Gear Hobbing Machine KOEPFER K 160

The K 160 Gear Hobbing Machine combines an innovative design principle with state-of-the-art technology and the wealth of experience gained during generations of gear cutting. Whether used for dry or wet machining, customized automation equipment and an extensive technology package make the K 160 Gear Hobbing Machine an optimal high-speed hobbing center for gear modules up to 2.5.

Gear hobbing on the Koepfer K 160

The Gear Hobbing Machine K 160 is equipped with the latest generation of 8-axis control systems and offers high hobbing head and work spindle speeds. This makes it possible to use high cutting speeds, even on those pinions and shafts with the fewest number of teeth. The base of the Gear Hobbing Machine is made out of MINERALIT® polymer concrete in a slant bed design. This machine base is great for vibration dampening and is also torsion and bending resistant. The slant bed design has an appropriate chip and coolant removal system. The machine body is also made of high-grade MINERALIT® polymer concrete and provides excellent damping properties. This results in better surface quality and long tool service lives.


The advantages:

  • Excellent vibration damping, resulting in extended tool life and superbsurface finishes
  • MINERALIT® polymer concrete is thermally stable which ensures constant production results

Throughput and idle times are governedby cutting speeds, the workpiece loading process and ease of setting – all economically decisive factors in the machining of large batch sizes. For the machining of pinions and shafts with the smallest number of teeth, or just gear hobbing, the K 160 from KOEPFER is the world’s fastest Gear Hobbing Machine with the lowest chip-to-chip times. Eight to ten years ago, the machining times for armature shafts, for example, were approximately 20 to 25 seconds. The K 160 Gear Hobbing Machine has, for the past several years, been the world’s only machine to reduce them to 8 to 10 seconds.

This position is due to the company’s outstanding capabilities, not only in the high-speed dry hobbing of planetary gears and the high-speed gear cutting of armature shafts, but also in the tangential milling of worm gears.
