A main component of this spindle is the motor, stored internally. Internal Motor: limited power and torque due to restricted space within the spindle housing; Speed Range: 20,000 [3]-60,000 RPM [2] (top speed according to design) Advantage: high top speed expands application use; Disadvantage: sensitive life range according to use
A laboratory centrifuge is a piece of laboratory equipment, driven by a motor, which spins liquid samples at high speed. There are various types of centrifuges, depending on the size and the sample capacity. [1]
Pneumatic tools are rated using several metrics: Free Speed (rpm), Air Pressure (psi/bar), Air Consumption (cfm/scfm or m3/min), Horse Power (hp), and spindle size.Each individual tool has its own specific requirements which determine their compatibility with air compressor systems.
The kinetic energy stored in the rotating flywheel is dissipated as heat at the weld interface as the flywheel speed decreases. Before welding, one of the workpieces is attached to the rotary chuck along with a flywheel of a given weight. The piece is then spun up to a high rate of rotation to store the required energy in the flywheel.
The latter being required when the rotor has a high service speed, or critical application (see ISO 201940 for recommended balancing tolerance.) Hard- and soft-bearing machines can be automated to remove weight automatically, such as by drilling or milling, but hard-bearing machines are more robust and reliable.
An ultracentrifuge is a centrifuge optimized for spinning a rotor at very high speeds, capable of generating acceleration as high as 1 000 000 g (approx. 9 800 km/s²). [1] There are two kinds of ultracentrifuges, the preparative and the analytical ultracentrifuge.

Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
