Grinding wheel truing and profiling machine - has primary dust extractor immediately above perforated baffle of projection system, and secondary one above light source

摘要

The projection system has a light source (1) below the working zone, covered by a transparent pane, the beam from it aimed at the zone. A perforated light shutter (5) is mounted in the path of the beam and close below the zone. A lens immediately above the zone and in the path of the beam is followed by a projection screen. Dust is extracted by a primary system aimed immediately above the shutter, and a secondary one aimed at an area above the light source. The pane (2) can be easily interchangeable and mounted in a position slightly inclined to the horizontal. The mouth of a pipe (20) delivering flushing liq. can be aimed at the pane. USE/ADVANTAGE - For grinding machine tools,with continuous observation of the trued profile during truing.
