Description: |
| "A machine tool compound work-table has at least two setting movements, and is provided with an optical projection unit for observing the setting of both movements. In a horizontal boring machine the work is carried on a table 5 rotatable on a carriage 4 slideable on a saddle 2, the latter being slidable on a bed 1. An optical projection unit 6, having a viewing screen 7 with graticules M, R, is carried by carriage 4, and reflectors 8, 9, are carried by the saddle 2, and table 5 respectively. Carriage 4 is moved until a light image supplied from source LM, is reflected by reflector 8, and is aligned with graticule M, and table 5 is rotated until light source LR is reflected by one of the reflectors 9, and is aligned with graticule M, the table then being aligned centrally with spindle 3. Reflectors 8, 9 may be 90 degree prisms, or front silvered mirrors, or deflecting prisms or lenses may be used. The table is set square and centrally by reflectors 8, 9, but more reflectors may be provided for other settings." |
