F-Grind AH Series High Precision Surface Grinder Offers a Smooth Finish

Kaast Machine Tools saddle-style F-Grind AH series high precision surface grinder features hardened, ground and PTFE (polytetrafluoroethylene) coated table guideways and offers full stress-relieved main parts designed for maximum rigidity, stability and grinding accuracy. Customers can add the optional AD5 auto downfeed system or an NC parallel dressing and compensating device.

This series of grinders also incorporates rapid traverse to working height and magnetization of the table, while also accommodating workpieces from 5.8 × 17.5” all the way up to 15.5 × 31”, depending on the model.

The spindle motors are available with up to 7.5 hp, offering speeds up to 2,900 rpm. The spindle runs in a class P4 high precision angular contact bearing, assuring runout accuracy better than 2 diameters. The cartridge-type spindle is completely sealed and lubricated for long working lifetime, providing high accuracy grinding and a long service life. The vertical feed moves in 0.01 mm (0.0004”) increments. The optional AD5 NC control decreases these vertical feed increments to 0.005 mm (0.0002”). The transverse feed works in 0.02 mm (0.0008”) increments. Auto downfeed from 0.001 – 0.999 mm (0.00004 – 0.04”) helps to ensure a smooth finish at the end of the job, the company says.
