NZ-518 Precision CNC Tap/Thread Grinder, 4-Axis 3-Linkage Control

The 4-axis 3-link CNC tap grinding machine produced by our company is designed according to the experience of German CNC thread grinding machine designers and operators, and through communication on the tap production site. It reflects practicality, economy, operation, maintenance, stability and efficiency.
The machine tool adopts an integral imported organic glass round door, which facilitates the unlimited operation and maintenance of the machine tool. The fully enclosed protective cover shell is in line with production safety. In order to cope with the production of special tools, the relative position relationship of the servo shaft of the equipment can be optimized, and the structure can correspond to the processing of a variety of tools.
The X and Y axes:imported linear motors and screw rail,

A axis: DD direct drive, which has high precision and resolution to ensure the high production efficiency and product quality of the tap.
