Definitions

the invention relates to a grinding body for a grinding machine for simultaneous internal and / or surface grinding of workpieces.
the invention has for its object to reduce the number of grinding units required for simultaneous grinding of bores and back or front face grinding of a workpiece.
both internal cylindrical and face grinding can be ground in a single control process.
the mushroom-shaped grinding body 2 is fastened to the grinding arbor 1 with its foot part 3 and its head part 4.
5 denotes a workpiece, the bore 6 of which is to be ground on the inside and also has flat surfaces 7, 8 and 9 to be ground.
the flat surfaces 7 and 9 are ground over the indicated separate grinding wheel 10, the grinding wheel 10 also occupying position 11.
the bore 6 and the flat surface 8 can be ground simultaneously with the mushroom-shaped grinding body 2. While the workpiece 5 rotates about the axis 12, the axis of rotation 13 of the grinding mandrel 1 is slightly inclined. At the same time, the foot part is conically tapered.
Inclination of the axis of rotation 13 to the axis 12 and conical taper of the foot part 3 are coordinated so that the bore 6 can be ground internally, but at the same time the flat surface of the head part 4 can grind the flat surface 8 of the workpiece. Because the rear flat surface of the head part 4 is arranged at right angles to the grinding surface of the foot part 3, the inclination of the grinding mandrel 1 results in the grinding only at the contact points indicated in the drawing.
Fig. 2 shows another arrangement of the grinding body, so that in addition to the bore 6 of the grinding body 2, the flat surface 9 facing the grinding mandrel 1 can be ground at the same time.
the foot part 3 is widened conically towards the head part 4.
the is on In this way, possible stable and short grinding arbors are of great advantage for face grinding.
the simultaneous plunge grinding of a hole with the corresponding flat face on the back is also possible with an oscillating motion thanks to the mushroom-shaped grinding body with a conical base and simultaneous inclination of the grinding mandrel.
