Honing machine

Abstract

A honing machine for honing a bore in a workpiece comprises a support structure fixed to the machine and at least one honing unit which is mounted on the support structure and which has a spindle unit (150) in which a spindle shaft (152) is rotatably mounted, wherein the spindle shaft (152) is rotatable about a spindle axis (155) by means of a rotary drive (450) and, at a tool-side end (153), has a device for the fastening of an expandable honing tool. The honing machine furthermore comprises a stroke drive for generating a stroke movement of the spindle unit (150) and an expansion drive (550) for expanding the honing tool, wherein the expansion drive is coupled to an advancing rod (460) which runs in the interior of the spindle shaft. The spindle unit (150) has a spindle unit housing (310) which has a first housing portion (310-1) for accommodating the rotary drive (450) and a second housing portion (310-2) for accommodating the expansion drive (550). The rotary drive (450) is accommodated in an exchangeable first cartridge (400) and the expansion drive (550) is accommodated in a second cartridge (500) which is exchangeable independently of the first cartridge (400), wherein the first cartridge (400) is introducible into the first housing portion (310-1) and the second cartridge (500) is introducible into the second housing portion (310-2).
