3 litre volumes of the speaker casings, whose shapely cones have no parallel surfaces
to create standing waves.
Turned specimens (base specimens) in general operated in the boundary lubrication regime (characterized by a constant friction coefficient with varying speed) as expected because parallel surfaces
theoretically do not generate hydrodynamic pressure.
It is easy to see that the potential between two parallel surfaces
is constant across the surface.
Flashbeam' is a light fixture glowing through layers of polycarbonate that creates reflection from ice crystal plates, with horizontal parallel surfaces
The Gustine R220 double-disc grinder processes parts from 18mm to 40mm wide with flat and parallel surfaces
Because large glazing panels are essentially thin-wall parts and must have parallel surfaces
for good optical qualities, molding machines must be able to maintain close parallelism of platens and molds--i.
Test location on the casting should have two parallel surfaces
The company specializes in flat, cylindrical, perpendicular and parallel surfaces
with extremely demanding geometry.
For example, consider a hand held micrometer that is calibrated for measuring work-pieces with flat and parallel surfaces
by measuring several calibrated gauge blocks (with surfaces larger than the micrometer anvil size).
Companies who are concerned about productivity in manufacturing of parts with precision flat and/or parallel surfaces
will want to look at Lapmaster's machines that bridge the gap between traditional lapping processes and double disc grinding.
These blocks are stacks of hardened steel rectangles with highly polished, flat, parallel surfaces
032 mm thickness with parallel surfaces
using a standard industrial splitter.
