Description:-For thickness and linearity calibration of curved surfaces.

This 90° Curved 5-Step block is machined from solid 2″ diameter bar with step thicknesses of .100″, .200″, .300″, .400″ and .500″. ID radius is a constant 0.50″ / 1.00″ diameter

Block Curvature:
500” step is a 1.0” radius
400” step is a 0.9” radius
300” step is a 0.8” radius
200” step is a 0.7” radius
100” step is a 0.6” radius
Step face is 1.000″ x 90° arc.
