Lathe is a machine tool for processing rotating workpiece.Lathe machines are mainly used to process shafts, discs, sleeves and other workpieces with swiveling surfaces.Lathe is the most widely used machine tools in the machine building and finishing industry. Milling machines and drilling machines and other rotating machinery are extended from the lathe. In Hong Kong and other places it was also been called the rotary bed.

Milling machine is a machine tool that primarily processing a variety of surfaces on a workpiece with a milling cutter.Milling machine can process plane, grooves, teeth, threads and spline shaft, but also more complex processing of the surface. Milling machine the efficiency of high planer, in the machinery manufacturing and repair sector is widely used.It is widely used in machinery manufacturing and repair departmentMilling machine is a versatile machine tool, Milling machine can process the plane (horizontal, vertical), trench (keyway, T-slot, dovetail slot, etc.), sub-tooth parts (gear, spline shaft, spiral surface) and a variety of surfaces.In addition, it can also be used for rotating body surface, bore processing and cutting work.
