Lastly, there is also a category called centerless cylindrical grinding, where no centers are needed to support the workpieces during machining. ... Grinding operations ...
For bore-grinding operations with oscillation, it is generally a good idea to design the quill long enough to be able to push at least ½ of the wheel thru the bottom of the bore you are grinding. Also, when moving to the deepest position, you need to consider how much room is required at the nose of the spindle for peripherals like coolant ...

The result is a truly round hole, with no taper or high or low spots, provided that the previous operations left enough stock so that the hone can clean up all the irregularities. Honing uses a large contact area at slow speed compared with grinding or fine boring, which use a small contact area at high speed.
The hole to be reamed with a machine reamer must be drilled or bored to within 0.010 inch of the finished size so that the machine reamer will only have to remove the cutter bit marks. Use plenty cutting fluid for reaming. ... The tool bit must be cooled frequently during the grinding operation by dip into the water. Never overheat a tool bit.
