Abstract
1297960 Machine tool details PRECISION GRINDING Ltd 14 Sept 1970 [28 Oct 1969] 52677/69 Headings B3B and B3K An attachment for use in a die-sinking machine comprises a base 11, a work-table 12 movable on the base in one direction by a fluid pressure ram 22, trunnions 14a, 14b, on the table for rotatably supporting a roller workpiece 15 which has a pinion 16 mounted thereon, a pattern table 17 connected to pinion 16 by a rack 20, and a second fluid pressure ram 30 for moving table 17 in a direction normal to the direction of movement of table 12. Work spindle 39 may be connected for vertical movement to stylus 38 by a pantograph, or by a fluid pressure valve 42, which controls a ram 43. Table 17 is held stationary so that workpiece 15 does not rotate, and table 12 is traversed. Fluid is then supplied to piston 30, and pattern table 17 is traversed so as to cause a small indexing of the workpiece, whereupon a further cut is made on the workpiece. In a modification, table 17 is reciprocated whilst the workpiece rotates, but is not traversed during cutting.
