Customize Your BLOCK-HEAD® Spindle
With your purchase of a BLOCK-HEAD® spindle, you have an unlimited choice of faceplates including metric call-outs, taper mounts, vacuum chucks, piloted mounts, collet chucks, etc. We can adapt a wide variety of other manufacturers’ hardware: Magnetic chucks, Northfield chucks, Micro-Centric chucks, HSK toolholders, encoders; just about any mounting configuration you can imagine.
Professional Instruments Company has long been the source for disk-testing spindles and chucks. We build a wide range of sizes and styles from simple screw-tensioned chuck/cover assemblies to pneumatically-operated, coverless, disk-centering types. Disk inside diameters range from 6-5/8” to 7mm, and the chucks may easily be changed with high accuracy intact thanks to our spherical-piloting system. Call for details.
