GENERAL
Martindale Undercutting Saws and V-Cutters
are
available in High-Speed Steel of
Tungsten-Carbide. Both types are
carefully
designed as to tooth form, hollow grind,
hardness, etc., and
manufactured to close
tolerances in our own plant.
While used primarily for undercutting mica and
slotting risers of commutators, Martindale Undercutting Saws and V-Cutters
are also used for cutting steel, aluminum, plastics, and other materials not
requiring set teeth.
Undercutting differs from ordinary machining in that,
instead of shearing, it is a combination of crushing, grinding, and
conveying. Mica is very abrasive and varies in hardness, making
necessary the very best design and production controls in the manufacture of
undercutting saws.
HIGH-SPEED STEEL SAWS and V-CUTTERS
These can be used on either portable or stationary equipment with spindle
speeds of 1,500 to 5,000 r.p.m.
(See Martindale Mica Undercutters for 16 Undercutters.)
