When grinding on a grinder, how many types of flat grinding can be divided into?

May 11, 2024

When operating a surface grinder, surface grinding can be categorized into several distinct types. In actuality, there exist multiple grinding methodologies applicable to surface grinders, and the optimal choice for our product hinges upon the specific circumstances. Moreover, a comprehensive understanding of the merits and demerits of each grinding approach is imperative for enhancing production efficiency.

Flat grinding on surface grinders typically attains a precision level within tolerance grades of IT7 to IT6, with surface roughness (RA) reaching 0.63 micrometers. Parallelism errors within a length of 1000 units are maintained at 0.01 millimeters.

The following are several grinding methodologies:

1. End Grinding: This entails grinding the ends of a workpiece, commonly employed to trim and ensure the flatness and precision of the workpiece's ends.

Pros: Suitable for trimming workpiece ends, ensuring flatness and precision.

Cons: Restricted to processing workpiece ends, with limited applicability to overall surface flatness requirements.

2. Surface Grinding: This method grinds the surface of a workpiece to achieve the required flatness and precision. It is the most prevalent form of flat grinding, typically executed using a surface grinder.

Pros: Broadly applicable for most flat grinding needs, achieving high precision and flatness requirements.

Cons: May not be suitable for certain special-shaped workpieces, such as curved surfaces.

3. Roll Grinding: Primarily employed to grind the surfaces of large rolling equipment such as metal rolls to restore their shape and surface quality.

Pros: Suitable for repairing the surfaces of large rolling equipment, restoring their shape and surface quality.

Cons: High equipment costs, potentially uneconomical for general workpieces.

4. Creep Feed Grinding: In this grinding type, the grinding wheel traverses over the workpiece at relatively low speeds but covers a large distance in each grinding cycle, often used for efficiently removing a substantial amount of material.

Pros: Efficiently removes a significant amount of material, suitable for high-speed material removal requirements.

Cons: May generate considerable heat, necessitating consideration of heat dissipation and workpiece deformation issues.

5. Peripheral Grinding: The grinding wheel's motion follows the periphery of the workpiece, commonly employed for surface grinding of cylindrical workpieces.

Pros: Suitable for surface grinding of cylindrical workpieces, achieving high precision and flatness requirements.

Cons: May not be suitable for non-cylindrical workpieces, with relatively lower processing efficiency.

6. Optical Grinding: Utilizes high-precision optical instruments and techniques for grinding to achieve exceptionally high surface quality and precision, often utilized in the manufacturing of optical components requiring exceptional precision.

Pros: Achieves extremely high surface quality and precision, suitable for applications with highly demanding surface quality requirements.

Cons: High equipment costs and technical requirements, potentially lower processing efficiency.

These methodologies offer diverse options for achieving desired flatness and precision in surface grinding operations.
