KOEPFER K 160 Horizontal Gear Hobbing Machine
The K 160 gear hobbing machine is equipped with the latest generation of eight-axis control systems, and offers a 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, made of MINERALIT® polymer concrete, provides excellent vibration dampening properties and is torsion and bending resistant. The slant bed design is ideal for chip and coolant removal. These factors result in better surface quality and longer tool service lives.
Throughput and idle times are governed by 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 is the world's fastest gear hobber 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.
