num 17-20 Product Description NUM num 17-20, also named NUM1720 CNC numerical control system, is a motion controller for machine tool CNC system. It is designed to realize multi-axis interpolation and spindle motion control, supporting precision machining control for old machine tool equipment renovation.

This controller delivers reliable motion control for machining tasks. The motion control supports multi-axis synchronous interpolation and positioning control. The motion control realizes G-code program parsing and axis speed adjustment. Stable motion control completes precision cutting action for numerical machine tools.

The built-in processing unit achieves steady program operation. The program operation executes CNC machining programs and logic instructions. The program operation supports tool compensation and coordinate offset calculation. Accurate program operation ensures machining action follows machining drawing requirements.

Embedded cabinet installation brings convenient system integration. System integration can be installed inside machine tool electrical cabinet. System integration connects servo drives and encoders via dedicated bus interface. Flexible system integration is widely used for legacy NUM CNC system spare replacement.

num 17-20 supports machining program storage, axis fault alarm and position monitoring function, equipped with servo bus and I/O terminal ports. It has status indicators for running state and fault diagnosis. Widely applied in milling machines, lathe equipment and precision machining production lines. This product is discontinued by NUM, mainly supplied as industrial spare parts, complying with NUM CNC industrial control standards.
