Roll extruding
processing, which is a technique of leveling and strengthening
the parts, is widely used in machine processing, hydraulic
pressure and rolling industries.t uses hard alloy trolley
to make the part surface produce plastic deformation,
so that the purpose of revising surface slight geometry
shapes and reducing the unevenness can be reached.The
unevenness of the surface can decrease from Ra3.2-Ra1.6
to Ra0.8-Ra0.4.Meanwhile, the roll extruding process itself
can change the fine texture of the metal surface, forming
favorable remaining stress and improving the machine performance
and life span. This machine can be installed onto
a machine tool. Under the condition of once installation,
roll extruding is directly proceeded, realizing roll extruding
instead of grinding. For great work pieces, the advantage
is especially marked. |
