**Maximum Grinding Wheel Speed**

“Peripheral velocity" is the speed that a point in the circumference moves per second. "Maximum operating speed"is the highest peripheral velocity for ensuring safe operation; in no circumstances should the speed be exceeded.

Maximum What is the calculation of grinding wheel speed? It is marked on each product.

**Grinding Wheel Speed Calculator (RPM) (Round Per Minute)**

Grinding Wheel Speed: The speed that a point in the circumference moves per second (Unit: m/s, m/min)

RPM: The number of times that a point in the circumference rotates per minute (Unit: min-1)

Assuming there is a point in the circumference, when this point moves 72m (4,300m per minute) per second, the Grinding Wheel Speed Calculator of wheel is 72m/s (4,300m/min). The number of rotations when wheel moves 72m/s is calculated according to the following equation.

The table below shows Grinding Wheel Speed Calculator that is converted to kilometer per hour for easy reference.

The careless operation is the common cause of serious accidents. Always pay attention to the safety.

Grinding wheels |
Maximum Grinding Wheel Speed （m/s） |
Kilometers per hour （km/ｈ） |

Resin flat grinding wheels | 50 | 180 |

Cut off wheel | 72 | 259 |

Resin depressed center wheels | 72 | 259 |

Resin depressed center wheels for high speed | 80 | 288 |

**Burst Grinding Wheel Speed Calculator**

The biggest factor affecting safety is the internal stress caused by centrifugal force.

Excessive speed will produce internal stress exceeding its strength which can result in a wheel breakage. The excessive speed is called “bursting peripheral velocity” and safety degree is established based on the bursting peripheral velocity.

The maximum Grinding Wheel is calculated by dividing the bursting peripheral velocity by a fixed safety factor. The safety factor for manual "center depressed wheel" and "cut off wheel" is "2.0".

It's the user's responsibility to not exceed these maximum Grinding Wheel Calculator
