PRECISION SURFACE & BLANCHARD GRINDING

Accubeam Laser offers Precision Surface and Blanchard Grinding Services to produce finished parts and components.  Grinding surfaces is used to produce a clean surface, straightening parts and reducing parts to a specified thickness within a tolerance.  Grinding is performed on all types of Ferrous Metals, including steel, alloys, carbon and more.

For a comprehensive list of cutting capabilities refer to our Specifications Table below.

We provide different types of grinding processes applied based on the material type and requirements; Blanchard, Vertical Spindle and Horizontal Surface.  Each type has unique characteristics that leave a finished product unmatched in the industry.

Precision Blanchard & Surface Grinding Capabilities

At Accubeam Laser, we offer Blanchard and precision surface grinding services to facilitate the production of finished parts and components made from ferrous metals. While both processes operate under the same basic principles, each produces different results and is used for different applications.

Both precision surface grinding and Blanchard grinding operations employ an abrasive tool to grind—or smooth—the part to produce a clean surface, straighten the part form, or reduce the part to a specific thickness. However, as precision grinding utilizes a small rotary tool and Blanchard grinding utilizes a large rotary tool, manufacturers generally use the former to finish smaller surfaces and achieve higher quality finishes and the latter to finish larger surfaces and remove greater amounts of material.

Our Blanchard Grinding Process

The Blanchard grinding process employs a cylindrical grinding wheel, vertical grinding spindle, and magnetic chuck. The chuck holds the unfinished material and, as it rotates, feeds the metal workpiece into the grinding wheel, allowing for material removal in two separate directions. This action creates the cross-hatching pattern characteristic of Blanchard grinding operations.

The combination of the magnetic chuck’s rotary motion and the grinding spindle’s grinding pressure allows manufacturers to create flat finishes within tight tolerances without damaging the substrate. As Blanchard grinding tools have large surface areas, they facilitate the removal of material from larger surface areas. However, the process is limited by the fact that it only finishes one side of the metal part.

This method of grinding is best suited for large machinery parts that need to meet specific flatness tolerances but don’t necessarily need a high degree of finish. Common applications include:

• Castings
• Die blocks
• Forgings
• Mold plates
• Rotary tables
• Stampings
• Vacuum chambers

Our Precision Grinding Principles

Manufacturers primarily employ precision grinding to achieve parts with precise, tight tolerance squareness and parallelism. These qualities are attained by the process’s incremental removal of small amounts of material from the workpiece, which also allows manufacturers to produce superior surface finishes and more accurate parts.

A typical precision grinding operation uses a cylindrical grinding tool covered with abrasive material. As the tool rotates and presses against the surface of the substrate with varying degrees of force, it removes as little material as possible to achieve the required finish. Depending on the product design and material of the workpiece, manufacturers employ a variety of different grinding wheels in varying sizes and abrasive materials.

At Accubeam, we offer the following precision grinding capabilities to produce a high-quality, polished finish:

• Diameter grinding
• Outside diameter grinding
• Planetary grinding
• Surface grinding

Typical applications of precision grinding include exact die manufacturing with edges squared to the center, round rods, and tools. We provide precision ground parts for industries such as:

• Aerospace
• Automotive
• Electronics
• Industrial
• Marine
• Medical
• Military
