Description

CNC High Speed Gear Grinding Machine
HÖFLER H 2500/3100 1974/1994
1994 completely reconditioned and retrofitted by HÖFLER and change to 10-axes CNC, extension of the diameter on 3100 mm, see also separate listing of the work, value approximately € 400,000, -

The universal profile grinder HOEFLER for gear wheels and pinions secures high accuracies by wear-free hydrostatic storage of grinding slide, workpiece slide and workpiece table. All corrections which are necessary for gear wheels can become grinded, also height and width crowning. The machine has a highly exact duplex partial worm gear and table spindle in special accuracy.

Main features:
-Full-CNC with color screen for 10 axes:
-X-/C-axes:generating-component
-Y-axes:diameter adjustment
-Z-axes:stroke positioning + length
-U- / W- / O- / Q-axes: dressing device
-V-axes:compensation of dressing amount
-B-axes:helix angle
-With cooling, but without evaporator
-Pitch testing device EVTM: The EVTM is suitable for use on gear cutting and measuring machines for checking the following: Tooth to tooth pitch errors, spacing errors, accumulated pitch errors, pitch span variations. Working range: module 1 - 40 mm, max. gear diameter: unlimited.
