MACHINE-TOOL

摘要

A machine-tool (10) has a drive (12) with a driven shaft (14) that carries out an intermittent rotary movement. The driven shaft (14) drives the drive shaft (18) which drives a tool (20) through an over riding clutch (16). The tool (20) thus carries out an almost continuous rotary movement that gradually changes into a discontinuous rotary movement when the machine is more strongly stressed. This machine-tool may be advantageously used as a manual machine-tool for screwing, boring, sawing, grinding and the like. The intermittent drive allows a high output torque to be generated with a low reaction torque.
