Dovetailed grooves are recommended since they hold the gaskets
in place and allow the gaskets to expand laterally as they are
deflected without constraining the sides. See below for ordering
information.
Manufacturing
Considerations
To use the groove properly, care must be exercised during its
manufacture.
- The flatness between the bottom of the groove and top surface
must be held flat within ± .001”. This can be
easily achieved by taking a fly-cut on the surface prior to
milling the groove. Note: do not remove the part from the mill
between making the fly-cut and milling the groove.
- In milling the groove, a regular o-ring groove using the dimensions
of "W" and "L" must be made first, then
finished up with a dovetail cutter.
- To deburr use a Scotch Brite pad (a deburring knife will destroy
the "W" tolerance).
Materials
These groove cutters are a custom cut two-fluted end mill made
of Carbide. The standard length is between 1.25”-2.0”.
Specific lengths are available on request.
