The cartridge-type spindle is completely sealed and lubricated in the newest Kaast grinderClick image to enlargeThe KAAST Machine Tools saddle- style F-Grind AH series high precision surface grinder features hardened, ground and PTFE (polytetrafluoroethylene) coated table guideways.

Full stress-relieved main parts ensure maximum rigidity, stability, and grinding accuracy. Customers can add the optional AD5 auto downfeed system or an NC parallel dressing and compensating device.

The F-Grind also have rapid traverse to working height and magnetization of the table, while accommodating work pieces from 5.8-in. x 17.5-in. all the way up to 15.5-in. x 31-in.

With 7.5 hp and speeds up to 2900 rpm, the spindle runs in a class P4 high precision angular contact bearing, assuring run-out accuracy better than 2 μm.

The cartridge-type spindle is completely sealed and lubricated, and the vertical feed moves in 0.01 mm (0.0004-in.) increments. The optional AD5 NC Control decreases these vertical feed increments to 0.005 mm (0.0002-in.).
