Abstract
Abstract For grinding selectively cylindrical and conical workpieces a grinding machine equipped with two grinding wheels is utilized, one of which wheels is mounted with its grinding face parallel to the axis of rotation of the workpiece, and the second of which wheels is mounted with its grinding face under an angle to said axis of the workpiece. This second wheel may be conical, or its axis of rotation may be mounted under an angle to the axis of the workpiece. In a preferred embodiment the axis of rotation of the second grinding wheel may be adjusted according to the desired angle of the cone portion of the workpiece, and if an easy to operate and reliable adjusting mechanism for the second grinding wheel is provided, the first of said grinding wheels may even be omitted.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
108 words
Apparatus for grinding selectively in one setting cylindrical and conical seats into a workpiece, the apparatus comprising a bench upon which are mounted a workpiece support, and at least two grinding wheel heads, the improvement comprising that one of the grinding wheel heads is laid out for grinding cylindrical seats, and the other wheel head or wheel heads respectively for grinding conical seats, and that the workpiece support can be moved in direction of the workpiece axis so far that the workpiece position into which cylindrical or conical seats respectively are to be ground, can be placed in front of the grinding wheel of the grinding-wheel head concerned.
Claim 2
Dependent Claim
108 words
Apparatus for grinding selectively in one setting cylindrical and conical seats into a workpiece, the apparatus comprising a bench upon which are mounted a workpiece support, and at least two grinding wheel heads, the improvement comprising that one of the grinding wheel heads is laid out for grinding cylindrical seats, and the other wheel head or wheel heads respectively for grinding conical seats, and that the workpiece support can be moved in direction of the workpiece axis so far that the workpiece position into which cylindrical or conical seats respectively are to be ground, can be placed in front of the grinding wheel of the grinding-wheel head concerned.
Claim 3
Dependent Claim
29 words
Apparatus according to claim 1, in which each grinding-wheel head for grinding conical seats carries a conical grinding wheel laid out according to the conical seats to be ground.
Claim 4
Dependent Claim
43 words
Apparatus according to claim 1, in which the spindle or wheel axis of a grinding-wheel head for grinding conical seats is disposed versus the axis of the workpiece, under an angle correspond-ing to the cone angle of the conical seat to be ground.
Claim 5
Dependent Claim
45 words
Apparatus according to claim 3, in which the grinding-wheel head which is angularly displaced versus the axis of the workpiece, is adjustable to at least two angle positions by swivelling around an axis which is perpendicular to the plane in which the workpiece axis lies.
Claim 6
Dependent Claim
18 words
Apparatus according to claim 4, in which the angle positions of the grinding-wheel head are limited by stops.
Claim 7
Dependent Claim
19 words
Apparatus according to claim 4, in which the angle positions of the grinding-wheel head may be selected at will.
