Comprehensive Guide to CNC Surface Grinders
Introduction
An industrial surface grinder is a machine that you use for smooth finishes on flat surfaces. This commonly used machining system cuts metallic and non-metallic materials with a grinding wheel, leaving a flat and sometimes smooth surface behind. To effectively flatten and smooth metal, precise grinding wheels are covered with abrasive particles. The maximum grinding width on various surface grinder lines ranges from 6.00″ to 27.55″, with lengths varying from 16″ to 82.67″.
