Scot Forge
produces guaranteed sound centered spindles and stepdowns
with any combination of round, square, flat or polygonal
dimensions, concentric or eccentric configurations, and
tapers or custom shapes. Parts with major diameters up to
65 inches, or greater if pieces are upset, can be produced
in weights up to 80,000 pounds in ferrous or non-ferrous
materials.
Our skilled craftsmen produce
precision forged spindles with dimensional uniformity that
other shops can achieve only by rough machining.
The
process begins when an entire piece is forged to the major
diameter and a fuller tool is used to mark the next step.
Then we forge that next step to a smaller diameter or taper
to create contoured, directional grain flow, thereby giving
the part greater strength and fatigue resistance.
In addition, Scot Forge's spindle forging
capabilities provide significant cost and material savings
when compared to machined bar spindle production. Scot
Forge can supply spindles precision forged or rough machined,
which can also be drilled, bored or trepanned if required.
