What does EXTREME DUTY SPINDLE mean?
Like everyone else in the stone machine business, we originally designed the machines to use electrospindles. The problem with the electrospindle approach is that electrospindles are a compromise. Trying to get enough power along with adequate bearings within a relatively small enclosure is not the best design. In fact, mixing water and electricity has never been a good idea! As we were trying to develop the ultimate spindle system for the Northwood CNC Stone Machining Centers, we looked to the machine tool industry for guidance. We developed the new Extreme Duty Spindle based on machine tool designs! The result is a spindle with unbelievable power especially at the spindle speeds used for machining stone. We backed this new design with a three (3) year spindle warranty (which is unheard of in the stone industry) and the cost for a replacement spindle can be as little as $6,000! Now that is a BREAKTHROUGH!
