Abstract

A polishing or grinding machine with a tool or carrier disc which receives a film of grinding or polishing medium and which is fitted, so that it can be varied in angle, on the end of a drive shaft, has an encasing guide which can be varied in angle with reference to the longitudinal axis of the shaft so that it encloses the periphery of the tool or the disc whose angular movements it follows. There are means to oppose the rotation of the guide on operating the machine and the drive shaft is in two parts. The means to oppose the guide rotation, which allows complete support of the tool on the surface to be machined, consists of an inflatable, pneumatic or hydraulic cushion which is supported on the top face of the guide.
