Precision Jig-Boring Spindle
This jig-boring spindle delivers extreme accuracy over a wide range of speeds. Excellently designed, it is supported with 2MM210WI-DUM grease-lubricated superprecision Bearings. With this spindle, holes located to an accuracy of one ten-thousandth (.0001) of an inch are bore round straight and to size limits of better than two ten-thousandths (.0002) of an inch.
High Speed Motorized Router
A specially matched duplex pair of Fafnir 2MM210WI-DU- FS223 superprecision ball bearings, mounted back-to-back at the work-end, affords the necessary bearing rigidity to permit routing through aluminum plate one inch thick with a single pass. The upper bearing is spring -loaded and permitted to float. Router is driven by a 30 hp motor at speeds up to 15,000 rpm, and uses oil mist lubrication.
