CNC grinding, or Computer Numerical Control (CNC) grinding, is a high-precision automated grinding process technology. CNC grinding is widely used in the field of mechanical processing, especially for parts with complex shapes and high precision requirements. The following is a detailed explanation of CNC grinding:

 

1. Principle of CNC Grinding:

CNC grinding uses computer programming to control the action of the grinder, and accurately controls the position and motion trajectory of the grinding wheel relative to the workpiece through the CNC system to achieve high-precision grinding.

 

2. Composition of CNC Grinding Machine:

CNC system: responsible for reading the processing program and controlling the movement of each axis of the machine tool.

Servo motor: drives the movement of each axis of the machine tool according to the instructions of the CNC system.

Grinding wheel spindle: rotates the grinding wheel at high speed for grinding.

Workpiece spindle: supports and drives the workpiece to rotate or move.

Automatic tool changer: Automatically change the grinding wheel or other grinding tools.
 

3. CNC grinding process:

Programming: Write CNC programs according to the geometric shape of the workpiece and the processing requirements.
Clamping: Fix the workpiece on the workpiece spindle to ensure processing accuracy.
Tool setting: Determine the relationship between the workpiece coordinate system and the machine tool coordinate system.
Processing: Start the CNC program, and the grinding wheel grinds according to the predetermined trajectory.
Measurement: Measure the workpiece size during or after processing to ensure processing accuracy.

 

4. CNC grinding types:

External cylindrical grinding: Grinding the outer surface or outer circle of the workpiece.
Internal cylindrical grinding: Grinding the inner surface or inner hole of the workpiece.
Surface grinding: Grinding the plane of the workpiece.
Centerless grinding: The workpiece is directly supported in the grinding area for grinding without a fixture.
Tool grinding: Grinding tools such as drills, milling cutters, etc.

 

5. CNC grinding characteristics:

High precision: CNC grinding can achieve extremely high processing accuracy and surface finish.
High efficiency: Automated control reduces clamping and adjustment time and improves production efficiency.
High complexity: Suitable for processing workpieces with complex shapes or difficult to grind manually.
Flexibility: Through programming, processing parameters can be quickly adjusted to meet the processing needs of different workpieces.

 

6. CNC grinding applications:

Automotive industry: used for processing high-precision parts such as engine parts and bearings.
Aerospace: used for precision processing of parts such as turbine blades and aviation instruments.
Medical devices: used for processing high-precision medical device parts.
Mold manufacturing: used for the manufacture and repair of precision molds.

 

7. CNC grinding precautions:

Grinding wheel selection: Select the appropriate grinding wheel according to the material and processing requirements.
Coolant use: Proper cooling can extend the life of the grinding wheel and improve the processing quality.
Wear monitoring: Regularly check the wear of the grinding wheel to ensure processing accuracy.
Program verification: Simulate and verify the program before actual processing to avoid processing errors.
The development of CNC grinding technology continues to drive the manufacturing industry towards higher efficiency and higher precision, and is one of the indispensable technologies for modern precision processing.
