This machine consists of a bed and table and a main housing carrying a single spindle 100hp motor-driven head having vertical feed and traverse movement.
The spindle is equipped with a No. 450 taper, 4-1/2" in diameter at the large end, ¾" diameter taper per foot.
The bed has a finished pad on the left-hand side.
The machine is equipped with two (2) Extra-Heavy Hydraulic Clamping Fixtures each weighing 140,000 lbs.
The Machine Bed has a weight bearing capacity of 740,000 lbs. That weight capacity is reduced by 140,000 lbs when using one of the Fixtures and by 280,000 lbs when using both of the Fixtures. Therefore, a work piece weighing up to 740,000 lbs may be machined when no Hydraulic Clamping Fixtures are being used, 600,000 lbs when one Hydraulic Clamping Fixture is being used and 460,000 lbs when both Hydraulic Clamping Fixtures are being used.
The Spindle, which is driven by a 100hp motor drive, is supported by a 22" diameter Quill.
This machine was designed to machine extra large Dies used in an extremely large Closed Die Forging Press.
NOTE: It is still installed under power and is available for immediate inspection and delivery.

Spindle speed, 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
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:
TABLE FEED: 3/4" - 36" PER MINUTE / RAPID TRAVERSE: 20 FT PER MINUTE
HEAD FEED: 1/4" - 12" PER MINUTE / RAPID TRAVERSE: 8 FT PER MINUTE
Quill is equipped with an electronic feed motor providing feed and traverse movements ranging from ¾" – 24" a minute
Pumps included for lubrication gearing in saddle, top plate, Johnson Drive, bed ways and feed boxes. Hand pumps for lubricating elevating screw nuts, saddle clamp gibs and ways. Zerk fittings used for remaining points.
MOTORS AND ELECTRICAL EQUIPMENT
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
2 Lubricating Pump Motors ½ hp, AC,
1 Quill Adjust Motor 3 hp, 1150/2300 RPM, DC, 65/2300 FPM
1 Coolant Pump Motor 2 hp
1 Table Clamp Motor 15 ft. lb., 1800 RPM, Shell type
230 volts, DC
440 volts, AC
The DC motors obtain their DC power from a 900 kw motor generator set which is driven by 150 hp motor.
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
5. The control cabinet mounted on the operators platform contains the following:
6. Hand operated rheostats for increasing or decreasing the feed rate of spindle speed within the range of the adjustable speed motors
7. 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
8. Meters are provided on the head to indicate the approximate feed rates, spindle speeds, and the approximate horsepower used by the head.
A motor driven coolant pump and piping supplies coolant to the cutter from a sump in the foundation. The foundation is constructed to drain coolant from around the machine into the sump.
The machine has a "shaker" type chip conveyor located in the foundation on the right hand side of the machine. This chip conveyor is arranged to discharge the chips into a sump at the front of the machine in the foundation.
(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.
Capacity – the fixture is adjustable for holding the following sizes of die blocks:
Thickness – 14" – 40"
Width – 36" – 90"
Length – 58" – 21-1/2 ft.Electrics – 440 volt, 3 phase, 60 cycle, AC as follows:
• (1) 7-1/2" HP AC motor for adjusting crossrail
• (1) 5 HP AC motor for driving the hydraulic pump motor
• Weight – estimated weight of each fixture and its parts is 140,000 lbs
• Magnetic Clamping on each fixture as follows:
• Fixture 1 – Sundstrand magnetic Control, 480 v AC - 244 DC
• Fixture 2 – Neutrofier II Magnetic Control, 280/400 AC – 244 DC
• 72" x 10" Magnetic face on each fixture
• Vertical travel – 64"
