The speed of the grinder must be compared to the speed marked on the wheel or package to make sure the machine's speed is at or below the maximum operating speed of the wheel. Surpassing this rating risks not just wheel breakage but also the safety of shop personnel. How do you calculate RPM on a grinding wheel?
For safe handling of grinding wheels see ANSI B7.1 standards. SOME GENERALIZED VALUES In the data below, the measurement of speed is based upon surface feet per minute and not rpm. The actual speed of the abrasive grit on the wheel periphery is set by the length of the path it takes as it revolves about the wheel axis.
RPM is a function of surface speed. In machining, surface speed represents the speed the cutter's outside edge travels. Use surface speed and the the cutter's size to calculate the …

Wheel RPM = Wheel Diameter = Grinding Wheel Speed Calculator - British Units CALCULATING SFPMThe 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.
In a mixer grinder, RPM denotes the rotational speed of the mixer blades. The faster the rotation, the more the RPM is. For example, if a mixer grinder has an RPM of …
A grinding machine is a production machine tool used in the manufacturing industry in which the grinding wheel is attached in the tool post and the workpiece is fixed to the work table and when the operation starts it removes the unwanted material to get the desired surface finish, correct size, and accurate shape of the workpiece.

If its a surface grinding job, try loading the jobs on a vertical grinding machine with a rotary table which is faster and more productive than a horizontal spindle, reciprocating machine. If there are multi levels, try maintaining a relief groove between levels rather than grinding up till a shoulder.
How do you calculate RPM on a grinding wheel? If you want to maintain exactly the same chip load, the equation is: new rpm = original rpm × (original diameter ÷ current diameter)1.5. So, if you were running your new 18″ wheel at 1,800 rpm, run it at 2,366 rpm [1,800 × (18 ÷ 15)1.5] once it gets down to 15″—again, within the safe speed.
RPM is a function of surface speed. In machining, surface speed represents the speed the cutter's outside edge travels. Use surface speed and the the cutter's size to calculate the rotation speed in revolutions per minute (RPM). Video of the Day Step 1 Convert surface speed to feet per minute. To convert from meters per second, multiply by 196.85.
The maximum operating speed is marked on every large grinding wheel (above 80mm in diameter) in two ways: The peripheral surface speed, given in metres per second. For example, 80m/s. The rotational speed, given in revolutions per minute. For example, 8500rpm. What is RPM of wheel? The "rpm" is the number of times the wheel …

Unfortunately, the published evidence for the effect of RPM on the particle size distribution is limited, and the effect may well be different for different grinders. What we can say is that faster RPMs typically deliver finer grinds for a given grind setting, producing more fines and a less modal grind size distribution.
