Snagging is a rough grinding application that removes unwanted metal with little consideration of surface finish. As such, it uses durable straight and straight cup wheels in horizontal and straight shaft grinding machines, although flaring cup wheels are used in right-angle grinders and various round and square-tipped cones and plugs also see use.
I use 60-grit belt for rough grinding the blade, then go to a 120-grit belt, which creates a fine enough finish prior to heat-treat. Use an OptiVISOR or other headband magnifier o check your progress. Any grinding scratches that remain will show up easier because of the red ink. Check for those remaining scratches under a good light.
Grinding is a more universally known process. Most workpieces can be ground, independent of their shape. Hard turning, on the other hand, has geometric limitations, as is the case with long and thin components. Wide surfaces can be finished effectively, often with a single plunge grind operation. In addition, with grinding a turn-free surface ...
Rough grinding. This step is about making one side of the glass concave. It will give your mirror its overall focal ratio. If you make the centre deep, you will end up with a fast telpe (e.g. F/D = 4) well suited for deep sky observations. On the opposite, a shallow mirror (e.g. F/D = 8) will be performing very well on planets and the moon. ...
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 pin journals are finish-ground …
