In addition to the X, Y and Z axes, there is a rotary axis and an oscillating axis. Rotary axis can be A axis can also be B or C axis, rotary axis can be rotated 360 degrees, swing axis is in addition to the rotary axis has been defined (such as the A axis), the remaining two axes in one (such as B or C), swing axis can only be in a certain angle swing (such as plus or minus 90 degrees) and can not be rotated 360 degrees.
Like horizontal machining centers have rotary axes belonging to the rotary table, so this is a four-axis linkage, the robot is not the fifth axis, if the rotary table to add a swing axis, so as to constitute a five-axis.
The axis that rotates around X is called the A axis, and the axes that rotate around Y and Z are called the B and C axes.
Machine tools (English name: machine tool) refers to the manufacture of machines, also known as workhorses or tool machines, customarily referred to as machine tools. Generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. Modern machinery manufacturing in the processing of mechanical parts in many ways: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc., but all of the higher precision requirements and surface roughness requirements of the finer parts, generally need to be in the machine tool with the method of cutting for the final processing. Machine tools play a major role in the modernization of the national economy.
The lathe is the main use of the lathe on the rotating workpiece turning machine tool. In the lathe can also be used to drill, reaming drill, reamer, tap, plate teeth and knurling tools for corresponding processing. Lathe is mainly used for processing shafts, disks, sets and other workpieces with rotating surfaces, is the most widely used class of machine tools in machinery manufacturing and repair factories.
