Cutting Speed. Cutting speed is defined as the speed at the outside edge of the tool as it is cutting. This is also known as surface speed. Surface speed, surface footage, and surface area are all directly related. If two tools of different sizes are turning at the same revolutions per minute (RPM), the larger tool has a greater surface speed.

Jogging speed is 4 mph to 6 mph (6.4 km/h to 9.6 km/h) Remember jogging and running is different for different people. Someone who is very tall and has a long stride will still be jogging at 6 mph whereas someone shorter with a small stride will be running fast at 6 mph. It's what works for you and not what the speed is called.

Cutting generates a lot of heat, making oil based coolant preferable. Many machining spindles require 2000 rpm or more, to provide adequate cutting torque, which means that you have to use relatively small diameter end mills in order to end up with surface speeds this low. If not using coolant, then max surface speed is 50 ft/min. Insulation

Impact mills differ from stone burr and metal burr models because they operate at a much higher speed due to an electric motor. Their grinding mechanism uses two stainless steel plates with teeth. When the plates spin at high speed, they burst the grains apart into smaller pieces.

Cutting speed. 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.

Good micro mills have 100-watt motors, which translates to around 1/8 horsepower. That's quite a lot for a miniaturist tool! Speed. Adjustable speed is a necessity because different materials are machined at different rates. Cutter diameter can also have an effect. Good mills have eight or more speeds available.

The percent of critical speed is the ratio (expressed as a percentage) of the actual mill speed and the Theoretical Critical Speed of that mill. The critical speed of a rotating mill is the RPM at which a grinding medium will begin to "centrifuge", namely will start rotating with the mill and therefore cease to carry out useful work.
