Abstract

1447365 Grinding MM WARD 20 Nov 1973 [29 Nov 1972] 55181/72 Heading B3D A grinding machine for forming a surface on a workpiece 11, such as a lathe cutting tool, comprises a table 7 for supporting the workpiece and movable along a path to define a path of travel between a pair of grinding wheels 4, 4<SP>1</SP>, and workpiece mounting means 8 associated with or mountable on the table and including means for setting the angle which a face of the workpiece makes with a plane containing its direction of travel during grinding. Each grinding wheel 4, 4<SP>1</SP> is driven by a respective motor 2, 2<SP>1</SP> and the wheels can be inclined towards one another by adjustment about pivotal axes on a frame 30. The distance between the wheels is adjustable by rotation of hand wheels 5, 5<SP>1</SP>, and the wheels are vertically adjustable by rotation of hand wheels 6, 6<SP>1</SP>. The table 7 is disposed below the grinding wheels and supports a rotary actuator 8 in a slot 9, the table being movable parallel to the slot. The actuator 8 carries a holder 10 for the workpiece 11 and consists of a pair of cylinders 14, 15 housing pistons formed with racks 12, 13 engaging a pinion 16 fast with a shaft 17 to which the holder is secured. The stroke of the pistons is determined by stops 18. In operation, as the table is advanced, fluid pressure is supplied to one of the cylinders so that the shaft 17 and holder is rotated about axis X-X to position the workpiece with one of its faces inclined to one side of the path of movement so that it is ground by one of the wheels as it is moved along the path. When the direction of table movement is reversed fluid pressure is supplied to the other cylinder to rotate shaft 17 and the holder so that the other face of the workpiece is inclined to the path and ground by the other wheel as it is moved along the path. The workpiece is thus ground on each side so as to taper from its leading edge 20. A number of shafts 17 may be provided for sequentially grinding a number of workpieces. In another embodiment a top plate of the table is swingable to either side of the path. The grinding wheels may be spaced along the path, the resetting of the workpiece occurring between the wheels.
