Length of table feed and traverse 24'
Length of quill travel from face of head 0-24"
Bed (3 ways):
Width across travel ways 112"
Overall length, approx. 52.5'
Table:
Working surface width 120"
Working surface length 24'
Overall length 26'
• Power operated lock
• Johnson Drive
• T-slots & Pin holes
Housing:
Width across housing ways 90"
Head:
• Movement on housing is made through two (2) elevating screws.
• Hand-operated locks
• Contains a quill which carries the spindle
• Spindle is driven by a 100 HP adjustable speed drive DC motor through gearing
• Flywheel on spindle drive
Spindle:
• The spindle is equipped with a No. 450 taper, 4-1/2" in diameter at the large end, ¾" diameter taper per foot
Quill:
Spindle quill diameter 22"
Power and hand adjustment 24"
• Power adjustment is independent of table and head movement and provides feed and traverse as shown under "Feed & Traverse Rates" below
• Hand operated lock
• Spindle Speeds: approx. 10-130 RPM
• The spindle has three (3) ranges of speed. The medium range starts at 14 RPM, and the high-speed range is full capacity of the 100 hp drive motor. The low speed range is at a limited capacity of 75 hp
Feed Distribution:
• The machine is arranged with two (2) 2-Motor feed boxes, one for the head feed located on the top of the housing and one for the table located on the left hand side of the bed
Feed & Traverse Rates:
Feed Rapid Traverse
Table ¾" – 36" per minute 20 ft. per min
Head ¼" – 12" per minute 8 ft. per min
• Quill is equipped with an electronic feed motor providing feed and traverse movements ranging from ¾" – 24" a minute
Motors and Electrical Equipment:
Qty. Description
1 Main Motor 100 hp, 575/1725 RPM, 230 volts, DC, drive motor
2 Feed Motor 7-1/2 hp, 575/2300 RPM, DC
2 Head & Table Drive Motors 40 hp, AC, foot mounted traverse motors
Electrics:
• 230 volts, DC
• 440 volts, AC
• The DC motors obtain their DC power from a 900 kw motor generator set which is driven by a 150 hp motor
Machine controls:
• The machine is primarily controlled via a portable pendant with the following controls:
1. Start and stop drive motor
2. Start, stop, reverse, jog, feed, fast feed and traverse table
3. Clamp table
4. Start, stop, reverse, jog, feed, fast feed and traverse bed
• The control cabinet mounted on the operators platform contains the following:
• Hand operated rheostats for increasing or decreasing the feed rate of spindle speed within the range of the adjustable speed motors
• Stop and start buttons for chip conveyor, coolant pump motor and lubrication pump motor. Limited switches are provided to limit travel of the table and head
• Meters are provided on the head to indicate the approximate feed rates, spindle speeds, and the approximate horsepower used by the head.
Weight:
Net weight 330,000 lbs.
(2) Hydraulic Clamping Fixtures:
• Fixtures consists of two complete clamping units, each unit including a housing, clamping rail and supporting brackets.
• Adjustable Clamping Rail - adjustable for clamping the various width of die blocks
• Housing is manually located on the table in one of the two positions; one position for blocks from 14" to 27" thick, and a second position for blocks 27" to 40" thick
• Each fixture is equipped with pendant operated though push buttons and selector switches
o Capacity – the fixture is adjustable for holding the following sizes of die blocks:
o Thickness – 14" – 40"
o Width – 36" – 90"
o Length – 58" – 21-1/2 ft.
o Electrics – 440 volt, 3 phase, 60 cycle, AC as follows:
o (1) 7-1/2" HP AC motor for adjusting crossrail
o (1) 5 HP AC motor for driving the hydraulic pump motor
o Weight – estimated weight of each fixture and its parts is 140,000 lbs
o Magnetic Clamping on each fixture as follows:
o Fixture 1 – Sundstrand magnetic Control, 480 v AC - 244 DC
o Fixture 2 – Neutrofier II Magnetic Control, 280/400 AC – 244 DC
o 72" x 10" Magnetic face on each fixture
o Travel:
o Vertical travel – 64"
o Hydraulic Unit: Vickers
Note:
Maximum recommended evenly distributed weight on table is 740,000 lbs. If one fixture is used then reduce by 140,000 lbs. If two fixtures are used then reduce by 280,000 lbs.

The machine was originally designed to perform general face milling operations on Very Large die blocks.
