New advances in abrasive technology allow machining center operators to perform surface finishing and other machining operations simultaneously, thereby reducing cycle times, improving quality, and saving time and money on offline finishing. Abrasive finishing tools can be easily integrated into CNC machine rotary tables or tool holding systems.
While contract machine shops are increasingly turning to these tools, others are wary of using abrasives in expensive CNC machining centers. This concern often stems from the common belief that “abrasives” (like sandpaper) leave behind a lot of grit and debris that can clog cooling lines or damage exposed slideways or bearings. These fears are largely unfounded.
It is a misconception that “abrasives” are the same thing. However, a distinction must be made between abrasives used for aggressive material removal and abrasive finishing tools. Finishing tools produce virtually no abrasive particles during use, and the amount of abrasive particles produced is comparable to the metal chips, grinding dust, and tool wear generated during the machining process.
Removing burrs and sharp edges from cross-drilled holes and other hard-to-reach areas such as undercuts, slots, crevices, or internal bores is essential. Failure to remove burrs can result in plugging or turbulence in the flow of fluids, lubricants, and gases through critical passages.
NamPower Abrasive Disc Brushes are made from flexible abrasive nylon filaments bonded to a fiber-reinforced thermoplastic matrix and contain a unique combination of ceramic and silicon carbide abrasives. The abrasive fibers act like flexible files, following the contours of the part, cleaning and filing the edges and surfaces of the part, ensuring maximum burr removal and the desired surface finish. Other common applications include edge smoothing, parts cleaning and rust removal.
