Device for machining and facing resilient materials
First Claim
1. A cylindrical grinding device for the machining and the facing of a workpiece made of resilient or semi-resilient material by the "in-feed" technique by using a grinding wheel of width at least equal to the length of said workpiece to be machined, characterized in that said device includes(a) means (32, 33, 39) which are capable of ensuring, for a certain time at the end of a machining operation, that a workpiece (25) is held in a position in which its rotation spindle (26) is located, at spindle supports (11), at a distance in relation to the rotation spindle (3) of the grinding wheel (2) equal to the sum of the theoretical radius of the desired finished workpiece and the radius of said grinding wheel;
- and(b) flexible drive means (27) allowing, during the rough-machining period, a slight drift of the rotation spindle (26) of the workpiece (25) being machined.

Abstract
A grinding device is provided for machining and facing workpieces made of resilient or semi-resilient materials. Said device comprises means (31) for holding the workpiece being processed after the machining operation to allow facing thereof. Machining can be improved by allowing limited drift of the workpiece, providing a flexible rotational drive, applying back pressure and using a recessed grinding wheel. This device can be used particularly for machining and facing drive rollers for office machines.
