rotary boring/tapping/cutting special machine The machine is mainly used to tap various rotary surfaces and end faces of rotary bodies. For example, turning internal and external cylinders, conical surfaces, ring grooves and turning surfaces, turning end faces and various ordinary threads are equipped with processing equipment, and various special surfaces are also processed. In the lathe can also be drilling, reaming, reaming, knurling and other work.

Milling machine is a widely used CNC lathe that can process planes (horizontal plane, vertical plane), grooves (keyways, T-grooves, dovetail grooves, etc.), tooth parts (gears, spline shafts, sprockets, spiral surfaces (threads, spiral grooves) and various surfaces; In addition, it can also be used to process the surface and inner hole of the rotating body and cut the workpiece; When the milling machine is working, the workpiece is installed on the workbench or the dividing head accessories. Milling cutter rotation, supplemented by the feed movement of the table or milling head, enables the workpiece to obtain the desired machined surface. Due to the use of multi-tool intermittent cutting, milling machine productivity is higher.

With the rise of China's manufacturing industry, CNC lathe customization has been widely used in machinery manufacturing to solve complex, precision, small batch, multi-variety parts processing problems. It is a flexible and efficient automatic machine tool, representing the development direction of modern machine tool control technology, is a typical mechanical and electrical product, and occupies a pivotal position. With the rapid development of precision machining technology and the continuous improvement of parts machining accuracy, higher requirements are put forward for the custom precision of CNC lathes.

In order to improve the accuracy of CNC lathes, iso230-2 or gb10931-89 are usually used to test the positioning accuracy of CNC deep hole drilling machines. For the same machine, due to the use of different standards, the accuracy of the position is also different. Therefore, when selecting the precision indicators of CNC lathes, attention should also be paid to the standards used. The positioning criteria for rotary boring/tapping/cutting special machines usually refer to the reverse deviation and positioning accuracy of each CNC shaft.
