A High Precision Surface Grinder is a specialized grinding machine designed to achieve exceptional accuracy, smooth surface finishes, and superior dimensional tolerances. It is widely used in industries such as tool manufacturing, automotive, aerospace, mold processing, and precision engineering, where micron-level precision is required. By utilizing a rigid machine structure, advanced spindle systems, and high-performance grinding wheels, the high precision surface grinder ensures repeatable and reliable results in both mass production and custom machining tasks.

Key Features of High Precision Surface Grinder

1. Rigid Structure for Stability

The machine is built with a heavy-duty cast iron or box-type frame that absorbs vibration during grinding. This ensures high rigidity and low deformation, even during continuous heavy-duty operations.

2. Precision Spindle System

Equipped with high-speed precision spindles, supported by high-quality bearings, the grinder maintains consistent wheel rotation accuracy. This results in minimal runout and improved surface finish quality.

3. Advanced Grinding Wheel Technology

High precision surface grinders use resin bond, vitrified bond, or diamond wheels to handle different materials, including hardened steel, carbide, ceramics, and non-ferrous metals. The correct wheel selection enhances efficiency and reduces thermal damage to the workpiece.

4. Micro-Feed Control

Operators can achieve micron-level feed adjustments through electronic handwheels or CNC control systems. This allows precise control over depth of cut and ensures uniform flatness and parallelism of the final workpiece.

5. Automatic Lubrication and Cooling System

The integrated lubrication system extends machine life by reducing wear on sliding components. At the same time, the cooling system minimizes heat generation during grinding, preventing workpiece deformation.

6. Safety and Operator Convenience

High precision surface grinders are designed with magnetic workholding tables, safety covers, and emergency stops, making them safe for operators while maintaining easy accessibility for loading and unloading workpieces.

Applications of High Precision Surface Grinder

Due to its accuracy and reliability, the high precision surface grinder is essential in:

• Tool & Die Making – achieving ultra-flat and smooth tool surfaces.

• Automotive Industry – machining engine components, transmission parts, and molds.

• Aerospace Industry – producing precision parts with tight tolerances.

• Electronics Manufacturing – grinding semiconductor components and precision connectors.
