Cutting, Carving And Grinding Machine Integrated CNC Work Center

Working Principle of Weihong CNC System

1. Instruction Input and Parsing

• Operators input processing instructions through the CNC system's human-machine interface (such as a touch screen or operation panel) or import pre-written G-code (a numerical control programming language containing parameters like motion trajectory, speed, and feed rate).
• The system's Central Processing Unit (CPU) decodes and calculates the instructions, converting abstract processing parameters into electrical signals recognizable by the equipment, specifying the movement path (e.g., straight line, arc, curve) and action sequence of the tool or workbench.

2. Motion Control and Driving

• Based on the parsed instructions, the system calculates the displacement, speed, and acceleration of each axis (e.g., X-axis, Y-axis, Z-axis) through a motion control card (core control module), and generates pulse signals or analog signals.
• The signals are transmitted to the servo driver, which controls the rotation of the servo motor (or stepper motor) according to the signals, thereby driving the mechanical transmission structure (such as ball screws and guide rails) to achieve precise displacement of the tool or workbench, ensuring that the processing trajectory is consistent with the instructions.

3. Real-Time Feedback and Closed-Loop Regulation

• Some high-end Weihong systems are equipped with position feedback devices (such as grating rulers and encoders) to monitor the actual position of the tool or workbench in real-time and transmit the data back to the control system.
• The system compares the deviation between the actual position and the commanded position, and dynamically corrects the output signal through the PID adjustment algorithm to compensate for errors (such as eliminating displacement deviations caused by mechanical gaps), ensuring processing accuracy (up to 0.01mm level).

4. Collaboration of Auxiliary Functions

• In addition to core motion control, the system also integrates control logic for auxiliary equipment, such as:
  • Controlling the cooling system (e.g., water pump) to start during processing to prevent tool overheating;
  • Linking with dust suction devices to reduce processing dust;
  • Monitoring equipment operating status (e.g., tool wear, overload protection) and triggering alarms or automatic shutdown to ensure safety.

Summary

The cutting-grinding all-in-one machine uses CNC control to coordinate cutting and grinding processes.​
It first takes processing parameters (path, speed, etc.) and converts them into signals to drive tool movement. The diamond-tipped cutting tool rotates at high speed, cutting stone to shape while adjusting speed for material hardness.​
After cutting, it switches to a grinding tool, which smooths edges by friction—controlling pressure and speed for a polished finish.​
Cooling and dust removal systems run simultaneously, with real-time feedback ensuring accuracy. This integrated workflow delivers efficient, precise stone processing.​
