8 Principles of Centerless Grinding - Metal Cutting ...
A larger abrasive grinding wheel; The beauty of centerless grinding is that the workpiece is held in place by the pressure of the rotating wheels. No fixturing is required, so the setup is simple and turnaround times are fast. And because the workpiece is rigidly supported, there is no deflection during the grinding operation.

The present invention relates to a method of grinding a concentrically clamped crankshaft, a crankshaft grinding machine for carrying out the method, and a crankshaft of high-alloy steel or cast material. The method provides for pin journals and main journals of the crankshaft to be ground in one set-up such that first, at least the main journals are rough-ground and then the …
Read This Before You Make a Knife - BLADE Magazine
With this type of setup, it would have been nice to have a reversible motor. I made close to three hundred knives with such a setup before I had a belt grinder. Once I built my first belt grinder, I only used the grinding wheel for rough-grinding blade profiles in order to save on sanding belts. The time required cancelled the savings in belts.
Method for grinding the main and rod bearings of a ...
In addition, the known method can be carried out in a single setup of the crankshaft. In this known method, the grinding started with the rough grinding of the main bearings so that the crankshaft is clamped in a precisely defined rotation axis, namely its defining geometrical longitudinal axis, for the grinding of the rod bearings.
