GRINDING FEEDS AND SPEEDS

High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels. On the other hand, very low grinding wheel speeds, in the order of 3,000 to 4,000 fpm (about 15 to 20 m/sec) are needed for the surface grinding of various types of .

What is the cutting time required for finishing 100mm width and 300mm length surface of a cast iron (JIS FC200) block when the cutter diameter is ø200mm, the number of inserts is 16, the cutting speed is 125m/min, and feed per tooth is 0.25mm. (spindle speed is 200min-1 ） （Answer） Calculate table feed per min vf=0.25×16×200=800mm/min Formula for Turning | MITSUBISHI MATERIALS .

What is the cutting time when 100mm workpiece is machined at 1000min-1 with feed = 0.2mm/rev ? (Answer) First, calculate the cutting length per min. from the feed and spindle speed. l=f×n=0.2×1000=200(mm/min) Substitute the answer above into the formula. Tc=lm÷l=100÷200=0.5(min)0.5×60=30(sec) The answer is 30 sec. iron ore ball mill grinding media calculation .

Ore Grinding Mills Mineral Processing Metallurgy. Rod mills see Fig 17 follow the general dimensions of tube mills with diameters from 3 to 6 ft and lengths from two to three times their diameter They differ from ball mills in that steel rods 3 or 4 in shorter than the mill length inside the liners are used as grinding media Rod mills are often run on tires and rollers instead of trunnions or ... GRINDING PARAMETERS CONVERSION .

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.
