External cylindrical grinding is one of the most common grinding processes and is mainly used for grinding rotationally symmetrical workpieces. It differs in the type of workpiece clamping and feed directions: The most common type of clamping in external cylindrical grinding is between centers. This means that the workpieces must be centered at ...

*Mostly/often an old grinder may be only a little scraping away from being a perfect dead true machine. A small TC grinder is worth its space for just grinding drill and end mill ends if nothing more. just a facet/flat drill point at 118 x 12 clearance and then hand back off the heal is much better than most hand sharpened drill points.

It means choosing the most appropriate wheel for a particular grinding machine operation. Wheel selection would depend on what abrasive is required, and characteristic of the wheels and also on operating conditions like a wheel and work speed, type and conditions of machines used.

Each grinding machine shall be inspected regularly before use, and colour coded. Abrasive wheels, grinding or cutting discs without the manufacturer's maximum RPM marked shall not be used. RPM (rotation per minute) of the wheel shall be more than a grinding machine if machine RPM exceeds than a wheel can break easily.

However, the corresponding centrifugal force would multiply by a factor of 1.167 × 1.167, or 1.36. To take a more extreme example, consider the same wheel with a maximum safe operating speed of 6,600 rpm run on a 5-inch right angle grinder at 10,000 rpm. This represents an over-speed of about 1.5 times the wheel's designed speed.
