lt supports online tuning of servo and real-time monitoring of servo state:

The auxiliary programming mode is simple, and track preview is allowed:

It provides user-defined interface;

PLC ladder diagram can be edited online as well as operated and monitored in real time;

It has network interface to support remote monitoring of system data and file transmission:

It is provided with GR-L series servo drive unit in standard configuration and servo motor

of high-resolution absoluteencoder

Support turning, milling and drilling complex machining
The system can be configured with 8 feed axes and 4 spindles, and all the spindles can be controlled as CS axes .Multiple machining operations such as turning, milling, drilling, and tapping can be completed with one time clamping realizing turn-milling machining in an easy, practical and efficient way and at a low cost. lt is provided with polar coordinate interpolation, cylindrical interpolation. rigid tapping and loop instructions for boring and drilling
Oscillating chip break
It supports the control mode for position/torque and is applicable for workpiece jointing between spindlesor devices for torque tailstock control. The following figure shows the structure of a torque control machine tool for jointing workpieces between spindles.

 
Additional axis control
Auxiliary axes are expansion axes used to support the auxiliary functions of the machine tool, such as loading and unloading mechanism, and tool change mechanism. The system supports four auxiliary axes

 
Parallel program function
The parallel program function is an auxiliary function that calls the designated program by triggering the G signal and can be executed concurrently with the automatic running program.


 
Servo operation commissioning and monitoring management functions 
The system supports on-line status monitoring of the servo system and manages the operation of servo parameters. The roundness data is analyzed based on real-time analysis of the operation data of the servo system to obtain optimal servo parameters and improve the high dynamic response performance of the servo system

Torque control 
The torque control function controls the motor to rotate at a certain rate, with a certain moment as the termination condition of the rotary motion. When the motor reaches the required torque, the current torque is maintained, so that the motor achieves dynamic balance with the external force in the rotation direction, which can be used for work piece docking and tailstock control between spindles

Remote monitoring and diagnosing
It supports remote monitoring, fault diagnosis and collection and analysis of reliability data for the CNC machine tool based on Ethernet LAN interfaces, including uploading and downloading of machining, parameter, and cutting tool deviation files and other data to realize remote monitoring function. It supports FTP communication transmission protocol.


Interworking gateway between CNC 
It supports gateway adaptation. The communication can be realized between CNC machine tools through gateways and reduces the cost by using less wiring and increases reliability.
