Surface Grinding Services & Expert Machines
W G Munn Hardchroming & Precision Grinding provides professional surface grinding services with fast turn-around times and precision results. Using advanced grinding machines, we ensure every workpiece achieves the highest quality finish, whether for industrial, automotive, or custom applications.
What is Surface Grinding?
Surface grinding is an abrasive process used to smooth flat surfaces of metallic or nonmetallic materials. The workpiece is secured in a chuck or holding device, and a rotating grinding wheel removes small amounts of material to create a precise, flat finish. This process not only improves aesthetics but also ensures the surface meets functional requirements.
Key components of a surface grinding machine include:
-
Abrasive wheel – removes material with thousands of cutting edges.
-
Chuck / workholding device – secures ferromagnetic pieces with magnetic chucks, and non-ferromagnetic or nonmetallic pieces with vacuum, mechanical, or machine vice support.
-
Reciprocating or rotary table – moves the workpiece under the grinding wheel with precision.
How a Surface Grinder Works
The grinding wheel rotates while the workpiece moves under it. Small increments of material are removed in each pass, producing a flat, smooth surface. Precision is often enhanced with a “spark out” process, passing the workpiece multiple times to eliminate minor inconsistencies.
Factors affecting grinding include:
-
Wheel material – Aluminum oxide for ductile materials, silicon oxide for brittle materials.
-
Workpiece material – Common materials include steel, cast iron, aluminum, stainless steel, brass, and some plastics. High-temperature grinding may affect material strength or magnetism.
-
Wheel shape & dressing – Straight or custom-shaped wheels can transfer different geometries to the workpiece.
