Designed for the inspection bench
Spherical contact. Practical measurement.
Ground and lapped
Chrome steel balls provide spherical contact for dimensional inspection.
Pairs for setup work
Two balls of each nominal size support comparative measurements and paired-contact setups.
Organised for the bench
A fitted case and red insert keep the set together between jobs.
Applications
Six ways to use a precision ball.
Rendered application studies illustrate the measuring principle. Cutaways expose contact geometry; tools and workpieces are not included.
Micrometer measuring faces
Compare readings at selected positions on the measuring faces.
Curved-wall thickness
Use a ball to contact the curved inside surface of a part with a flat outside reference.
Centre-drill depth
Seat a ball in the centre hole to compare its axial position to a datum.
Seat depth
Compare a seated ball’s protrusion or depth relative to a reference face.
Collet setup
Ball spacers can support a collet-boring setup using a suitable retention method.
Tapered bores
Compare the seating positions of two known ball diameters to evaluate taper geometry.
