The 3M™ CBN Polyimide Wheel 184PN is used to generate the flute which is the helical or straight groove in the body of the cutting tools made of tool steel and high speed steel. The polyimide bond wheel construction offers excellent form retention and increased thermal stability under higher temperature grinding operations. High Quality Flute Grinding The 3M™ CBN Polyimide Wheel 184PN line is specifically designed for the production and re-sharpening of high speed steel and tool steels cutting tools. The wheel used to generate the flute which is the helical or straight groove in the body of the tool. This processes require the highest level of quality that the 3M™ CBN Polyimide Wheel 184PN provides. The 3M™ CBN Polyimide Wheel 184PN line uses a hybrid bond system which offers increased thermal stability compared to other bond systems. This allows 184PN to grind at higher cut rates and maintain form under higher temperature grinding conditions where phenolic bond systems undergo thermal and chemical deterioration. The Right Wheel for Every Job 3M provides a broad portfolio of superabrasive wheels used for your round tool relief and clearance angle applications. From short runs and re-sharpening to "lights-out" and long production runs, 3M has the wheel design to meet your needs.
