GRINDING PARAMETERS CONVERSION CALCULATOR

CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure.

Surface Grinding Problems | BladeForums

Jul 16, 2008 · I bought a surface grinder about 9 months ago (Harbor Freight) and have been having problems getting a good finish on the parts that I grind. It seems that the stone is loading up and burning the material. I always dress the stone before using, but can t even get through grinding a small part before I start getting burn marks in the metal.

Surface Hardening: Hard Turning or Grinding? | Gear ...

The grinding wheel is composed of many random irregular bonded abrasives, and therefore the machined surface has a random distribution of grinding marks. In contrast, hard turning is performed by a geometrically defined cutting edge, and therefore the feed marks have a uniform spacing determined by the prescribed feed rate.

Which Grinding Wheel Should I Choose? | Norton

Nov 21, 2018 · A grinding wheel is a precision tool with thousands of cutting points on its surface - abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores.. These pores are hollow spaces between abrasive grains and the bond, which help with the clearance of discarded metal chips in the grinding process.
