Carbide coating to
prevent slippage in
bending operations
An application of Carbinite coating can tighten machinery’s grip on
material during bending operations. When applied to the gripper
arm in the holding area of mandrel or rotary draw systems the
textured coating is said to prevent material from slipping or rolling
during bending.
Carbinite is a
carbide coating
that iselectrofused
to a base metal to
add texture. This
texture increases
the coefficient of
friction between
the clamping
surface and
the workpiece
allowing for a
strong, solid grip
in the holding and clamping areas of the tube bending process.
Carbinite is applied by electrofusion, resulting in an incredibly
strong bond since the carbide is fused into the base metal, not
just applied onto it as in spray welds. Bulk heating is not required,
so tool temper and heat treat are not affected. If needed, it can be
applied and reapplied without stripping away existing layers.
If a metal tube or pipe requires a sequence of bends, an
application in the gripper area of a seeker or plainer will help
ensure that when the dye rotates around and the arm comes in
contact with the material, slippage does not occur. This prevents
the material from being knocked out of plane.
The coating is available in several grades, leaving various
textures ranging from 40 to 320 emery grit. It can be applied to all
steels, including stainless, as well as to certain aluminium alloys
such as 6061 and 7075.
