Teeny Tiny Vee Block
Part Number: VB-187-CPM. For balls from 3/16" (.1875", 4.76mm) through 1/4" (.25", 6.35mm).
Building a teeny tiny vee block for Kinematic applications presents some unusual challenges. The design chosen uses the well-proven cylindrical post-mounted vee block. The post is used to both locate and clamp the vee block in position. The cylindrical post is precision ground to .250 inches.
The flange adjacent to the post is ground flat and square to the post. The post is drilled and tapped for a 4-40 hold down screw. After precision grinding the flat prismatic faces of the tiny vee block, these faces are precision lapped. The vee block is constructed from a high chrome, high carbon, Martensitic stainless steel that is hardened to 58 HRC minimum. This ultra fine-grained material provides excellent repeatability with good fret resistance.
This very small size component will match balls from just under three sixteenth's (3/16" ) of an inch ( 4.8 mm ) to just over one quarter inch ( 1/4" ) ( 6.4 mm ) diameter. Our part number on this item is VB-187-CPM.
