Higher RPM leads to less torque, which means a higher risk of the tooling losing traction and spin out. Therefore, it's always safe to check what the optimal RPM is for the tool you are working with. Grinding Wheels and Blades: Below 7" in diameter, these tooling (and thus RPM) are designed for angle grinders.

A high speed steel "G" drill is being used prior to reaming a 3/8 hole on a piece of 1095 steel with a brinnel hardness of 300. Calculate the RPM setting to perform the drilling and reaming operations. Cutting Speed = 40 (fpm) Diameter of Cutter = 0.3701 (G drill) Half the speed for reaming would be = 432 / 2 = 216 RPM for reaming.
rotational speed is: All grinding wheels have a resistance threshold. If a grinding wheel shatters when rotating, the pieces that fly off can cause serious damage. Abrasives manufacturers therefore indicate ... rotational speed (rpm) n Figure 6 Power 0% 14% 34% 61% Figure 7 Torque 0% 14% 34% 61% Figure 8. n

For example, operating a reinforced, 9inch diameter, type 27 wheel rated for a maximum speed of 6,600 rpm on a 7inch angle grinder with a speed of 7,700 rpm failing to properly maintain machine components, particularly governors on pneumatic machines and linkages on floorstand ...
Grinding machine/wheel RPM:- GRINDING WHEEL SAFETY Always check grinding wheel/cutting wheel Maximum RPM is greater than the grinding machine Maximum RPM AG-4 Grinding Machine RPM between 10800 to 12000 (Depend on manufactures, in India mostly use Bosch its RPM is 12000). AG-4 Grinding Wheel RPM between 12500 to 13500 (Depend …
Multiply the circumference by your rpm to get your surface speed per minute. Multiply surface speed/min by your radial infeed amount per pass (assuming traverse grinding). If you are only infeeding on one side use half your radial infeed amount. This result would be your specific removal rate or Q'. This rate will be inch² or mm² per minute.
In angle grinders, the rotation speed of the working shaft varies from 2.5 to 12 thousand revolutions per minute. The working range is in the range from 3000 to 6000 rpm. As a rule, the manufacturer sets the optimum rotation speed for his machine depending on the motor power, and sets this parameter at the design stage.
Ensure that permissible RPM and/or surface speed in m/s or sfpm corresponds to the grinding wheel and the machine intended for use. Use paper …
that reduces the grinding machine's deviating force. ★ 20 Hp with 220V~240V/380V~440V three phase,15 Kw motor can offer enough power for grinding, an additional weight 25 kg*2 increase grinder's total weight that make it more efficient compare with other machines.
Always check grinding wheel/cutting wheel Maximum RPM is greater than the grinding machine Maximum RPM. AG-4 Grinding Machine RPM between 10800 to 12000 (Depend on manufactures, in India mostly use Bosch its RPM is 12000). AG-4 Grinding Wheel RPM between 12500 to 13500 (Depend on manufactures). AG-7 Grinding Machine RPM 8500.
All Norton grinding wheels are marked with a maximum operating speed in RPM. Most machines, and especially CNC machines, use Surface Feet Per Minute (SFPM) as an input, which requires operators to do the conversion.

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 a positive or a negative value as shown in Figure 5.
The All-In-Wonder can be set up as an 6" Flat Lap, a 6 1/2" Trim Saw, and/or a 1" Drum Grinder / Shaper. Each of the three machines can be set up in just minutes. Water cooled system means no messy oil to clean up. Faster RPM motor allows you to quickly finish the finest cabs possible.
For example, operating a reinforced, 9-inch diameter, Type 27 wheel rated for a maximum speed of 6,600 rpm on a 7-inch angle grinder with a speed of 7,700 rpm can cause the wheel to crack. This cracking can lead to breakage later. The following actions—all of which are not recommended—can also lead to an over-speed condition:
