A tailstock, also known as a foot stock, is a device often used as part of an engineering lathe, wood-turning lathe, or used in conjunction with a rotary table on a milling machine. It is usually used to apply support to the longitudinal rotary axis of a workpiece being machined. Speeds and feeds for parting and grooving. 12 x SFPM = RPM. Cutting speed 2. Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Both settings produced a smooth surface finish. 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. A lathe is a machine used to turn both metal and wood and is comprised of many parts. From the stand to the chuck, lathe parts work in unison to create a finished item for the craftsman or woman. A lathe is assembled from parts such as the motor, drive belts and tail stock. Drill bit cutting speeds are very important in the drilling of metals. The depth of the cut and the feed rate will also affect the cutting speed, but not to as great an extent as the work hardness. Optimizing feed rates and speeds: 1. 1) The machine is ready to shaken itself to bits - too greedy with cut, depth or speed.
