Who has more RPM between a grinding machine and its

If you are referring to a grinding machines motor and the grinding wheel as a direct drive they would have the same RPM. The wheel will travel further distance but they will have the same amount of rotations per minute. If there is some gearing/pully system then the motor will always have the most RPM as the gearing is introduced to increase torque.

RPM SFPM Defined Mach-B Grinding Wheel Shaping

06-05-2014  Grinding Wheel Diameter = 24″, Machine Speed = 600 RPM; SFPM = 3772.8. As the wheel wears to, say, 21″, SFPM will slow to 3144 if RPM stays at 600. To maintain 3772.8 SFPM the RPM will need to be increased to 720.

The Right RPM for Diamond Grinding, Cutting, Drilling ...

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.

Speeds and feeds - Wikipedia

By means of the machine's software and variable speed electric motors, the lathe can increase the RPM of the spindle as the cutter gets closer to the center of the part. Grinding wheels are designed to be run at a maximum safe speed, the spindle speed of the grinding machine may be variable but this should only be changed with due attention to the safe working speed of the wheel.

Grinding machine - Wikipedia

A grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding, it is a type of machining using an abrasive wheel as the cutting tool.Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.. Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high ...

WB - RPM and vibration sensor Technological benefits

Vibration is the enemy! Imbalance is the most common cause of vibration on grinding machines. Vibration can be eliminated by means of an active balancing system that monitors the signals from the vibration sensors (accelerometers) and the rotation speed (RPM) and corrects the imbalance by applying a manual adjustment (corrective weights on the grinding wheel support flange).
