Blanchard Surface Grinder

If you’ve been in the grinding world as long as we have, you’re quick to spot a part that was processed on a Blanchard grinder by its distinct cross-hatch surface pattern. Along with producing this unmistakable and pleasing design, Blanchard grinders are recognized as one of the most reliable, rugged and robust machine tools ever invented. With the first Blanchard surface grinder debuting in its New England birthplace in the early 1900s, Blanchards have a long history, with many thousands of these workhorse grinders still operating in factories worldwide.

The benefits of Blanchard grinder rebuilding and remanufacturing can often outweigh the advantages of buying new. These processes involve the restoration and repair of an older grinder, resulting in improved performance, reliability, efficiency and safety. By addressing mechanical issues, upgrading technology and replacing worn parts, a rebuilt or remanufactured grinder can often perform better than a brand-new one.

GCH Machinery uses only high-quality parts and components for grinder rebuild and remanufacturing projects. Supplied by our sister company, GCH Tool Group, each piece is manufactured to OEM specifications or better, and is guaranteed for maximum performance.

We are experts in the field of grinder remanufacturing. Our extensive hands-on knowledge allows us to design machines that meet the most stringent specifications, including those as tight as .5μ (micron).

The engineering team at GCH Machinery has over 150 years of combined experience in grinder machine rebuilding and remanufacturing. Specializing in fields ranging from mechanical and electrical engineering to software and machine building and design, our team members are passionate about grinders and machine tools.

We are confident in our team’s ability to deliver the best results for your grinding needs.

Rotary Surface Grinding

A Blanchard grinder is a surface grinder with a vertical spindle and a magnetic rotating table that holds the part (ferrous) in place. (Nonferrous parts are affixed to the grinder with specialized tooling, generally designed and engineered for the subject part.) Once in the machine, the grinding wheel comes down and processes the entire part surface simultaneously, removing stock from one side of the part.  Industry-wide, Blanchard grinding is often referred to as rotary surface grinding.

Limitless Possibilities

While other surface grinders are limited by the size of the part they can handle, Blanchard grinders welcome large parts, easily managing anything from 24” to 90”. Typical parts processed on a Blanchard include:

• Plate stock
• Rotary tables
• Large castings and forgings
• Large stampings
• Molds and dies

Known for their versatility, a single Blanchard surface grinder can handle a number of different part sizes. Blanchard grinders easily adapt to automation, including robots, gantries, hoppers and feeders and infeed conveyors.  Blanchards are ideally suited to gaging systems, which can be installed as part of a grinder remanufacture or upgrade.

Available Blanchard Upgrades and Accessories

We offer a wide range of grinder accessories for your Blanchard surface grinder. Those accessories include: 

• Automation options
• Chillers
• CNC controls (Siemens, Allen-Bradley, FANUC, NUM, Omron, Mitsubishi)
• Coolant filtration systems
• Fire suppression systems
• Full enclosures
• Mist collectors
