(Basic Operation)
To help you understand drum and rotor turning read the
following that helps explain the features, operation and
principles of rotor, drum and flywheel resurfacing.
Horizontal Spindle / Arbor
The spindle (horizontal main shaft) is motor driven and
turns the arbor (main rod with threaded tip) upon which
the brake drums or rotors are mounted. When turning the
drum, rotor or flywheel via the arbor and holding a cutting
tool against the braking surface, metal can be removed
resulting in a smooth finish that meets original factory
specifications. Smooth brake surfaces will extend the lift of
the brake pads and increase brake operation efficiency.
Spindle Speed
Spindle speed is adjustable by changing the position of
the belt on the rear of the lathe. See page 37 .
Cross Feed Assembly
The cross feed (forward and aft) draws the tool bit
(micro-dial twin cutters or boring bar) across the face of a
brake rotor or flywheel when the cross feed (Rotor Feed)
Motor is engaged.
The cross feed may also be operated manually without
engaging the motor using the Cross Feed Hand Wheel.
Horizontal Spindle / Arbor Feed
By selecting the spindle feed (Drum Feed) motor, the
spindle and arbor will move the mounted brake drum to
the left. This feeds the drum braking surface across the
cutting tool (boring bar) as the drum moves away. Spindle
feed may also be done manually without engaging the
spindle feed motor by using the spindle feed hand wheel.
Spindle feed rate refers to the distance the spindle is
moved for each revolution. This speed is variable and can
be adjusted using the Feed Speed Control Dial.
The Spindle Feed may also be operated manually without
engaging the motor using the Spindle Feed Hand Wheel.
