These tooling plates are designed to be mounted to the Sherline 4″ CNC Rotary table (P/N 3700-CNC, 8730 or 8700)
to hold parts that are being laser scanned. Each plate has a pattern of
10-32 threaded holes for use in holding fixtures to align parts for 3D
laser scanning. A series of concentric circles are also machined into
the face of the plate to aid in visual centering of the parts to be
scanned. An access hole is provided that should be aligned with the
oiler hole on the surface of the rotary table for lubrication. On the
bottom of the table an alignment protrusion is provided that helps
center the plate on the counter-bored hole in the center of the rotary
table. Four 10-32 socket head cap screws and T-nuts are provided with
each plate for securing it to the T-slots on the rotary table’s surface.
The aluminum plates have a tough black anodized finish.
three plates are shown here in one photo as a means of comparison. They
come in sizes 8″, 10″ and 12″ in diameter. All are designed to be used
on Sherline 4″ Rotary Tables.
Notes on use of the plates
These plates are not intended for machining operations. A radial
force at the outer diameter of the plate will exert more force on the
rotary table worm and worm gear than the 4″ rotary table was designed
for. This plate was designed for laser scanning ONLY. Because the
scanning plate is much larger than our 4″ rotary table, all parts that
are mounted on the plate for scanning must be centered on the plate.
This will locate the weight load in the middle of the rotary table.
