What Is the Metal Grinding Process?

The metal grinding process is a subtractive machining method that removes small amounts of material to create a smooth, flat, or round surface. While it’s often used as a finishing step after cutting or milling, grinding can also serve as a primary method for shaping metal. Whether you’re working with raw bar stock or parts fresh off a CNC machine, grinding helps refine them by removing burrs, correcting dimensional deviations, and polishing surfaces for function or aesthetics. The right grinding tools for metal depend on the material type, finish requirements, and part geometry.

Our Core Metal Grinding Services

We offer multiple grinding techniques to accommodate a wide range of part types and finishes. Here’s how each method supports your production needs:

Surface Grinding

This is one of the most widely used techniques in our shop. Surface grinding delivers flat, even finishes using a high-speed rotating abrasive wheel. It’s ideal for preparing components with strict thickness tolerances and clean face surfaces.

Cylindrical Grinding

Used for external surfaces, cylindrical grinding rotates the workpiece while applying a grinding wheel along its length. This ensures precise roundness and diameter accuracy, especially for parts like shafts, rods, and bushings.

Centerless Grinding

A go-to solution for high-volume production, centerless grinding does not require the part to be held between centers. Instead, it passes through a series of guides and grinding wheels to achieve round, accurate profiles. This is a fast, repeatable method for cylindrical components.

Blanchard Grinding

Blanchard grinding, also known as rotary surface grinding, is best for large, flat surfaces. It’s commonly used for plates, blocks, and machine bases. This method quickly removes stock while creating an even, uniform finish across large areas.

Advanced Metal Grinding Equipment for Better Outcomes

Our shop is equipped with professional-grade metal grinder machines that support both light finishing work and more aggressive material removal. Each job starts with careful planning and tool selection to ensure the best results. By pairing the right machine with the correct abrasive, we minimize errors and maximize efficiency. The use of high-performance machines ensures smoother finishes, tighter tolerances, and repeatable results. Whether you’re looking for flatness, roundness, or a polished edge, we match the method to your end goal.

Selecting the Best Grinder for Metal Finishing

Choosing the best grinder for metal depends on three main factors: the type of metal, the size and shape of the workpiece, and the desired finish. Our team helps guide you through these decisions so you get the most efficient, cost-effective grinding method for your application. Some of the metals we commonly grind include:

• Stainless steel
• Mild and carbon steels
• Aluminum alloys
• Brass and bronze
• Hardened tool steels

No matter the material, we apply consistent standards of care, heat management, and finish control throughout the process.
