Abstract
A roll grinder system including a roll grinder bed of high dynamic stiffness, having a roll support and a grinding wheel support fixedly mounted to the roll grinder bed. The roll grinder bed is comprised of a monolithic epoxy granite block with a steel plate embedded in the top surface and a steel plate embedded in the bottom surface. The bed for the support for the roll being ground is rigidly affixed to the top plate. The bed for the traversing carriage of the grinding wheel head is also rigidly affixed to the top plate. A bed for the caliper is affixed to a lateral side of the block. The grinding wheel and the caliper traverse along the axis of the roll being ground. Vibration isolators are disposed below the bottom plate of the block.

A roll grinder with vibration resistance, comprising:
- a roll grinder bed comprising a monolithic block having a top side and a bottom side;
- a top plate on the top side of the block;
- a roll support and a grinding wheel support fixedly and rigidly mounted on the roll top plate, the roll grinder bed being of high dynamic stiffness for rigidly and accurately supporting the grinding wheel support and the roll support;
- the roll support being for supporting a roll to be ground;
- a grinding wheel having a rotation axis and being supported on the grinding wheel support, the grinding wheel support traversing in a direction along the axis of the grinding wheel with respect to the roll grinder bed, the grinding wheel being so shaped and the wheel support being so located that as the grinding wheel is rotated and traverses, the grinding wheel grinds a roll on the roll support;
- and
- vibration isolators located below the roll grinder bed for flexibly attaching the roll grinder bed on a floor.
