Spindle
The spindle and quill are manufactured from special forged steel
and are constructed to reduce vibration to a minimum. The quill
is machined with utmost accuracy and the teeth cut from the
solid, and is also ground to ensure maintained accuracy for
the feed rate. The spindle is mounted in double row roller and
thrust bearings protected by a grease seal. The spindle is secured
by an anti-vibration lock-nut at the top of the spindle. The
spindle and quill assembly are fitted with a counter-weight
providing uniform smoothness of the entire stroke, the quill
over-travel is obliviated by a special safety device. An arm
raising and lowering special safety device prevents over-travel.

and arm is actuated by a hydraulic unit operated by push buttons,
the hydraulic system being divided to allow the operator to
move the arm vertically without affecting the spindle alignment
and similarly unlock the head or column independently. |
Headstock
The headstock is a totally enclosed unit including the gearing
for the spindle speeds and feeds.. The feed
mechanism also provides a depth stop mechanism. All gears are
made of nickel chrome steel and are hardened and ground, with
lubrication provided by an automatic lubrication pump.
Electrical System
