Grinding Wheel Safety: Respect The Maximum Speed
In the example mentioned, changing from 6,600 rpm to 7,700 rpm multiplies the speed by 1.167. 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.Grinders and Grinding Machines Information | Engineering360,Grinders and grinding machines can use single-phase or three-phase power and are available in a range of voltages. 60 Hz power is used in North America. 50 Hz power is used internationally. Some devices require manual loading, setup, and operation.What motor should I use in grinding machine with 3000 rpm,,Most hand held and bench mounted grinding / drilling machines are fractional horse power, say, less than 1000 watts. If you make a Google search on the web, you will land up with dozens of manufacturers for not only grinding machines, but other hand / mounted tools; too. This is a entire subject by itself !
