grinding time is estimated for a desired energy input, E, in kWh/t. The mill speed is manually set and confirmed with a revolution counter. After grinding, the slurry is separated from the charge, dried, the solids rotary split and screen analyzed in duplicate. The torque readings and mill speed are used to calculate the energy input.

Grinding wheel speeds should be maintalned with-in a range of 5000 to 6500 feet per minute (1525 to 1980 meters per mm), unless special conditions prevall or equipment and wheels designed for substantially higher wheel speeds are used.
In grinding operation, elastic deformations of the grinding machine and the grinding wheel induce a residual stock removal of workpiece. On the other hand, thermal expansions of the workpiece and the grinding wheel increase the depth of cut. Therefore, calculation of a ground depth of cut and/or the grinding time has to be considered by the elastic deformations and the thermal expansions.
Aug 03, 2021· Finally, calculate the cycle time. Using the formula we find the cycle time to be 1000/480 = 2.083 min/part. FAQ. What is cycle time? A cycle time is a measure of how long it takes to produce a given part. For example, a part may take 20min to run 10 parts. The cycle time …
Jun 04, 2018· The dress speed ratio is the relationship between the dress roll velocity (V r ) in sfm or m/sec and the grinding wheel velocity (V s) in sfm or m/sec. and can be calculated using the following equation: Speed ratio = V r ÷ V s. The dress speed ratio can be …

Oct 24, 2018· Here are some representative process data to illustrate a NCD creep-feed grinding calculation: Max. diameter of wheel: 16 inch. Min. diameter of wheel: 10.5 inch. Usable abrasive (radial): (16 – 10.5) / 2 = 2.75 inches. Dress amount per part (radial): 0.006 inch. Wheel life is then 2.75 / 0.006 = 458 parts per wheel.
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.
