The vitrified grindstone speed of 30 ~ 35 m / s; resin bond wheel speed of 35 of 50 m / s. When surface burns, should the grinding wheel speed is reduced to 16 ~ 20 m / s.
Workpiece speed, when the workpiece diameter less than 50 mm, n = 120 to 150 r / min; greater than 50 mm, n = 40 to 80 r / min. The plane fine grinding with a wheel Cylindrical, table movement speed is generally 15 ~ 20 m / min, coarse grinding of 50 m / min. The grinding depth infeed amount of hours whichever is greater, infeed to the large amount of small value. The kibbled depth of 0.04 ~ 0.08 mm, fine grinding depth of 0.01 mm. Grinding wheel dressing should be reduced depth.flap wheel
When the vertical cylindrical grinding feed rate, coarse grinding (0.2 ~~ 0.7) mm / B r fine grinding (0.2 to 0.3) B mm / r; internal grinding Longitudinal feed kibble when (0.4 ~ 0.7) B mm / r, fine grinding (0.25 to 0.4) B mm / r; Wheel cylindrical plane cross feed mill, coarse grinding (0.3 ~ 0.7) B mm / dst, fine grinding time (0.05 ~ 0.1) B mm / dst.
