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.
Our Clinton, Wisconsin plant specializes in custom flanged-end spindles with heads that are upset in a variety of shapes, including single, tapered, or multiple diameter.
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.

Starting material is delivered to the induction heating element and
heated to forging temperature.
Once at temperature the material is moved to the upset press.
