MAKINO INTRODUCE THE V99 AND V99L HIGH-SPEED VMC FOR LARGE MOLD MANUFACTURING
AUBURN
HILLS, MI—December 2006—Makino’s V99 and V99L vertical machining centers (VMC) are engineered to
provide superb accuracy and high-speed performance previously unobtainable with
large die/mold milling machines. These capabilities of the V99 and V99L help
eliminate or reduce benchwork and post-production polishing on large die and
mold work.
“The V99
and V99L provide the speed, accuracy and stability needed to tackle large molds
and dies effectively,” says Bill Howard, VMC product manager at Makino. “Most
importantly, both come with Makino’s unmatched expertise in the die/mold
manufacturing market.”
The V99 has
an X-, Y-, and Z- axes of 59 x 39.4 x 31.5 inches (1,500 x 1,000 x 800 mm),
with rapid traverse and cutting federates of 787 IPM (20,000 mm/min.). A
large worktable of 70.8 x 39.4 inches (1,800 x 1,000 mm) accepts a maximum
workpiece of 70.8 x 39.4 x 25.6 inches (1,800 x 1,000 x 650 mm) weighing up to
8,800 pounds (4,000 kg). The V99 is a rugged
50,692-pound (23,000 kg) machine that is 15.4 feet wide x 13.5 feet deep x 11.5
feet tall (4,700 x 4,100 x 3,500 mm)
The V99L
has an X-, Y-, and Z- axes of 78.7 x 39.4 x 31.5 inches (2,000 x 1,000 x 800
mm), with rapid traverse and cutting federates of 787 IPM (20,000
mm/min.). A large worktable of 90.5 x 39.4 inches (2,300 x 1,000 mm)
accepts a maximum workpiece of 90.5 x 39.4 x 25.6 inches (2,300 x 1,000 x 650
mm) weighing up to 8,800 pounds (4,000 kg). The V99L is a rugged 57,304-pound (26,000 kg) machine that is 17.1 feet
wide x 13.5 feet deep x 11.5 feet tall (5,200 x 4,100 x 3,500 mm)
Both
machines come with a
#40 taper 20,000-RPM or a #50 taper 12,000-RPM spindle as standard
equipment. This accommodates a maximum tool size of 4.7 inches (120 mm)
in diameter by 11.8 inches (120 mm) in length and weighing 17.6 pounds (8 kg)
on the #40 taper - or 5.7 inches (145 mm) in diameter by 15.7 inches (400 mm)
in length and weighing 44 pounds (20 kg) on the #50 taper. An HSK A100,
18,000 RPM spindle is optional, as is five-axis capability.
The V99 and
the V99L incorporate 0.05 micron scale feedback on all axes providing a
positioning accuracy of ±0.000060 inches (±0.0015 mm) and repeatability of ±
0.000040 inches (±0.001 mm) for superb positioning and contouring accuracy for
continuous machining of large workpieces.
“When
you’re dealing with large workpieces, stiffness and rigidity can make a huge
impact,” Howard continues. “Finishing times can last several days, the
workpieces can be very heavy and hard to set up, and eliminating steps like
stress relieving or having the ability to hard mill can save huge amounts of
time and money. It takes a serious machine and serious know-how to machine
large molds efficiently. That’s what the V99 and Makino’s application engineers
provide.”
Features
and Benefits
High-efficiency
machining requires a system for quick, efficient evacuation of chips. A highly
reliable, quick, efficient work zone chip removal system is standard with both
the V99 and the V99L, with other system expansions available as options.
Eighteen outlet
holes are provided below the table of the machines to reliably catch chips,
regardless of the table position. Four built-in hinge-type chip conveyors
evacuate chips at high speed toward the front of the machine.
The bed and
column are protected by covers to prevent any freshly cut hot chips and coolant
from direct contact with their cast-iron surfaces. The areas around the column
and the bed as well as underneath the bed are insulated to eliminate thermal
changes in the cast-iron machine structure caused by variation in the shop
temperature.
Thorough
machine usage studies by Makino led to the ergonomic design of the V99 and
V99L, providing excellent access to the worktable from three sides of the
machine. The automatic tool changer (ATC) magazine door features an extra
large opening for the comfortable changing of heavy tools. A 30-tool ATC is standard equipment,
with options available for 30, 40, 60 and 80 tools – depending upon the spindle
configuration.
Both the
V99 and V99L are equipped with the Makino Professional 5 Control utilizing
Windows CE™ to provide a stable, secure, platform with reliable performance on
the NC side, while providing an operator friendly graphical user interface
(GUI). This latest generation machine tool control offer large, color,
touch sensitive, on-screen, menu driven applications.
Icons
provide “hot links” and quick access to critical information that may be
required by the operator. In addition, the new control platform provides
all of the functions typical of a PC (cut, paste, copy, find, replace, etc.)
that are rarely available on a machine tool control. Advanced data
management technology and Makino's proprietary, next
generation Super Geometric Intelligence (SGI.4) servo control deliver the
lowest cycle times available.
