Tool ram device, in particular for a generating slotting machine

摘要

A gear shaping assembly has a cutting tool (3) on a shock shaft, a guidance head and a guide passage (10) providing push/pull/twist guidance to the shaft. The push/pull action is driven by a hydraulic piston, and a rifling unit for the twist action. The twist-action profile (6) and counter-profile (11) form a discrete fluid-sealed unit. The counter-profile (11) acts as the seal incorporating the working piston cylinder (60, 61).
