CRANKSHAFT grinding & Indexing. When a crankshaft is turned to an undersize, it can and does change the stroke and degrees apart of each rod journal. To index a crank, first the machinist has to know where the stroke and degrees (swing) are. Once this is established, with the right machine to start with, the crankshaft can be indexed for both ...

1. Cutting speed is defined as the speed (usually in feet per minute) of a tool when it is cutting the work. 2. Feed rate is defined as tool's distance travelled during one spindle revolution. 3. Feed rate and cutting speed determine the rate of material removal, power requirements, and surface finish. 4.
Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.

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.
Answer (1 of 2): 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 a...
The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

Grinding wheel speeds are generally given in SFPM while machine speeds are usually noted in RPM. Also to know is, how fast does a grinding wheel spin? Grinding wheel speeds should be maintalned with-in a range of 5000 to 6500 feet per minute (1525 to 1980 meters per mm), unless special conditions prevall or equipment and wheels designed for ...
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 on manufactures).

Use the correct wheel for the machine's size and speed, and the work to be performed. • A cutting disc should not be used for grinding. The RPM rating of the disc/blade must be higher than that of the angle grinder. Adjust guards to deflect flying particles away from operator. • Use an 180° guard between operator & wheel.
