Professional CNC & Surface Grinding

What is CNC Grinding?

CNC grinding (Computer Numerical Control Grinding) is a high-precision machining technology that uses computer programs to control grinding tools to process the surface of workpieces. Through surface grinding, the bottom, side, or end faces of a workpiece can achieve micron-level flatness and smoothness. Using internal/external cylindrical grinding or centerless grinding, cylindrical, conical, and complex surfaces can also be machined with high accuracy. This is suitable for producing mechanical components, automotive brake discs, aerospace structural parts, and electronic device components.

Core Concept Diagram:

[Workpiece Fixed] ← High-Speed Rotating / Reciprocal Grinding Tool → [Precision Workpiece Surface]

• Workpiece Fixed: The workpiece is firmly clamped to ensure stability during machining.
• Grinding Tool: The grinding wheel rotates at high speed, precisely removing material along programmed paths.
• Precision Workpiece Surface: The workpiece gradually reaches the designed dimensions and surface roughness.

Features of CNC Grinding

1. High Precision: Program-controlled grinding paths achieve micron-level dimensional accuracy.
2. Versatility: Supports surface grinding, internal/external cylindrical grinding, centerless grinding, and form grinding.
3. Efficiency and Flexibility: Grinding processes can be adjusted for rough or fine finishing to balance production speed and part quality.
4. Consistent Repeatability: The same program can be reused to ensure uniformity in batch production.

Applications of CNC Grinding

• Mechanical Manufacturing: Various precision components
• Automotive Industry: Brake discs, drive shafts
• Aerospace: Structural parts, power transmission shafts
• Electronics: High-precision parts and connectors

Why CNC Grinding is Important

• Enhances surface precision and flatness of parts
• Reduces friction and wear, extending part lifespan
• Supports both prototyping and high-volume production efficiently
• Achieves micron-level tolerance even for complex-shaped parts

Tips for Understanding

1. Imagine the workpiece as a block or cylinder fixed on the worktable.
2. The grinding wheel rotates at high speed, following the programmed path to grind the surface.
3. Workpiece fixed + grinding tool operation simultaneously results in high-precision machining.

Summary

CNC grinding is a combination of workpiece fixed + high-speed grinding tool, controlled by computer programs, achieving high precision, efficiency, and repeatability. Both CNC grinding and surface grinding effectively enhance part accuracy and durability, meeting the high-quality requirements of the mechanical, automotive, aerospace, and electronics industries.
