Specification

 

workpiece dia. 280 mm 
module 6

The gear hobbing machine HURTH WF 280 is characterized by high productivity, a stationary table, and an operating convenience. Scales are mounted on all movable slides showing each position analog. That abbreviates set up times for repetitive operations. Hydraulic clamping devices for column, head and shift slide provide high hobbing accuracy. When changing the work piece manually or changing the hob cutter, such features grant a considerable time reduction. The electronic distance sensor (Linotast) takes over the exact positioning and constant cutting depth by using a hydro-cylinder with linear amplifier.
