This five-station fixture gage checks critical dimensions and geometry of precision ceramic cylinders 4 1/2” long x .375” O.D. After the indicators are set to a master, the cylinders are staged individually in two V rests and checked as follows:

• Station 1 – Overall length 4.500” ±.010”
• Station 2 – Squareness of ends to axis and parallelism of ends to within .002”
• Station 3 – Longitudinal bow to within .005”/inch
• Station 4 – Out-of-roundness to within .003” T.I.R.
• Station 5 – Wall thickness .030” ±.003”

Features of this multi-indicator gage:

• Micrometer head height adjustment of the work-staging V rests
• Precision ball slide mounts for dial indicators at stations 3-4
• Wear-resisting carbide contacts at all gaging station.

Inserting ceramic cylinder in gage to check squareness and parallelism of ends, longitudinal bow and out-of-roundness.
