What is a Surface Grinding Machine?

A surface grinder, also known as a magnetic surface grinding machine,
is used for achieving ultra-flat and precise finishes on metal surfaces. The magnetic chuck holds
ferrous workpieces in place while the grinding wheel removes material, achieving tolerances in the micron range.

Types of Surface Grinders

1) Manual Surface Grinder

Low-cost, ideal for small workshops, requires operator control for table movement.

2) Automatic Surface Grinder

Equipped with automatic table feed; higher productivity and consistent results; good for semi-industrial use.

3) CNC Surface Grinder

Programmable, highly precise and repeatable; used for large-scale production and complex profiles.

Applications of Surface Grinding Machines

• Finishing of molds (plastic injection & die molds)
• Grinding of plates and frames to achieve flatness and parallelism
• Toolmaking: cutting tools, punches, dies, and fixtures
• Precision automotive and CNC machined parts
• Achieving micro-level surface finish for industrial components
