Automate Deburring / Finishing to Speed Throughput


New abrasive technology delivers automated deburring and surface finishing in single operation


By automating


deburring operations instead of handling it


as part of a secondary process offline, CNC part and component manufacturers are


reducing labor costs and speeding high-


volume parts finishing. Now, with a


new advance in


abrasive technology, machining center operators are now able to add surface


finishing simultaneously in the same operation to speed things even further.


For Eric Sun, Founder of Orange Vise Company, the unique combination of automated deburring and surfacing finishing allowed his company to eliminate several time consuming and laborious processes that had been slowing them down.


Orange Vise manufactures CNC machine vises and quick change fixturing components in Orange County, California, using a Mori Seiki NHX4000 high speed horizontal machining center.


As with most CNC machining centers, however, the process of deburring typically involved taking the part offline and having it addressed by hand using a variety of abrasive tools. Sun not only wanted to automate the process, but also eliminate a messy grinding process the company was using to achieve a specific surface finish.


According to Sun, the company’s CNC machine vises are constructed of different materials and surface treatments. The body of the vise is made of cast iron with selectively hardened surfaces. The vise also comes with a variety of different sized with different heat treatments.


The hardened surfaces, which could measure as high as 50-60 on the Rockwell C Scale, required grinding because milling cutters would wear out too quickly. Out of necessity, Orange Vise would also grind the non-critical, unhardened surfaces to create a uniform appearance over the entire workpiece.


“This process involved removing, cleaning, and then repositioning parts several times to be able to grind each face. It was time intensive, particularly for the work that was purely cosmetic,” explains Sun.


It was at this time that Sun discovered a new abrasive tool from Brush Research Manufacturing, the abrasive technology company known for inventing the Flex-Hone Tool and turning it into a global brand.


The company’s new line of NamPower abrasive disc brushes are designed to allow CNC operators to automate the deburring process while delivering an ideal surface finish in the same operation.

the NamPower brush over a messy time consuming grinding process.
