Is this new technology (as in last few years)? Seems like putting rollers on a pinion is something that engineers probably thought of decades ago. Does anyone else offer a roller pinion design?
Regardless, it is a very cool system. Ballscrews are impractical for large routers on low to medium budgets. Companies like Thermwood require support arms to prevent whip. Komo uses helical R&P. Bridge mills use massive ballscrews that probably cost more than high end routers.
Roller pinion... relatively inexpensive, easy to manufacture, lube-free. Pretty much the perfect linear drive system for woodworking IMO. |
