A portable magnetic drilling machine is faster and more portable alternative to hole making machines such as the drill press, and is more accurate than a hand drill. A portable magnetic drilling machine is used on steel or other magnetic materials. It gives an accuracy of 0.01 mm ...
Plasma CNC Pipe Cutting . Hot cutting refers to a process in which materials are cut using a thermal torch. One of the most common techniques is oxy-fuel gas cutting, which is used extensively for cutting carbon and low-alloy steels. However, its efficiency diminishes as the alloy content of the material increases, limiting its applicability ...
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.
The magnetic gear is a magnetic coupling device that renders a mechanical ratio between two magnetically-coupled devices such that: They have a ratio of rotation or translational movement between input and output which may be unity in the case of a pure magnetic coupling or one of many gear ratios in a magnetic gearbox .
