Over the past decade, CNC grinders have been developed to a level of capability for producing round cutting tools and special parts almost beyond imagination. At the same time, superabrasive wheel manufacturers have developed wheel formulations to keep pace with this increased capability. However, unlike truing and dressing of conventional abrasives, superabrasive wheels often require two distinctly different operations. Wheels are trued to make them perfectly concentric to the spindle and/or to create a specific form in the grinding face. Then in many cases they then must be dressed to make them ready to grind. This is where stand-alone truing and dressing machines–such as the 3MTM Truing & Dressing Machine E339 VHM–come in. They are designed to simultaneously true and dress single wheels or multiwheel packs away from the grinding machine. While an absolute necessity for machines without on-line truing capability, they enhance the on- machine truing systems by minimizing the amount of stock that they need to deal with. 20 <strong>thesharpedge</strong> Issue Six 2008 3M's E339V truing and dressing machine: a fast and accurate way to dress diamond and CBN wheels. true for quality Truing and dressing off-line can improve part quality and productivity – by Wayne Wheeler, 3M. There is no restriction as to the type of wheel that can be trued in this manner allowing for optimization of the wheel specification without compromising wheel performance. All bond systems may be quickly trued and dressed, and with quick change adapters, the wheels are trued to very exacting tolerances while mounted on the spindle on which they will run in the grinder. Wheel packs for the next job can be created while the CNC grinder itself continues to produce parts, minimizing changeover time between runs. In addition, it affords quick touch-up capability with minimal down time for those machines without online dressers. The bottom line is that off-line truing and dressing capability will increase your productivity through always having the next wheel pack ready to go. In addition, the ease and speed with which wheel shapes can be maintained affords greater opportunity to maintain part quality through more consistently accurate wheel shape. Stand-alone wheel dressers mean you can have the next wheel pack ready to go.
