MASON,
OH--September 2006--Makino is continuing to expand and diversify its product offerings by
introducing the a71 into Makino’s competitively-priced, 1-Series line of
horizontal machining centers (HMC). The a71 can help drive out manufacturing
costs by providing high-speed performance, high reliability, durability,
simplicity and throughput.
The a71 is
ideal for manufacturing applications that require less precision but the same
throughput and reliability of Makino’s premiere A-Series machines.
The a71
will be on display at the International Machine Tool Show (IMTS) at McCormick Place in Chicago, Illinois
September 6-13, 2006. Visit Booth # 8301 in Hall A of the South Building
to learn more about this and other technological innovations.
Also plan
to visit Booth # D-4110 in the EDM Pavilion at IMTS to see demonstration on
equipment and processes that meet the demand for micro-dimensions and
ultra-high precision EDMing.

Benefits and Features
The primary benefits of the Makino a71 include swift axis movement and faster
spindle acceleration/deceleration than other HMCs. Out-of-cut time is
diminished because of the machine’s standard ring-type, 60-tool magazine with
short seek times (6 to 12 seconds) that is complemented by a quick automatic
tool changer that has fast tool-to-tool (1.7 seconds) and chip-to-chip (3.2
seconds) times.
Makino’s
a71 is the largest in the 1-Series line to date and can handle a payload of
1,540 pounds (700 kg). It has a 19.7-inch (500-mm) pallet and a standard 50
taper, 10,000-rpm spindle with exceptional acceleration characteristics and
minimal vibration. The spindle is equipped with a
300-psi coolant system. Options include a high-powered, 6,000-rpm spindle.
Rapid traverse rate of the a71 is equal to the a51 at 1,968 ipm (50 m/min),
while cutting feedrate is higher at 1,968 ipm (50 m/min). The a71 is capable of
simultaneous B-axis movement with tool change and X-, Y-, Z-axis travel of 28.7
x 28.7 x 31.5 inches (730 x 730 x 800 mm).
The a71’s
footprint, which is 118 x 190 inches (3,000 x 4,825 mm), is smaller than most
competitive machines and is designed for easy maintenance access around the
entire perimeter. High-volume chip evacuation is facilitated by a wide-center
trough with a standard rear discharge lift up chip conveyor that includes a coolant
leakage protection design.
Other
features include an automatic pallet changer with safety guard, a standard
three-point support system, an ergonomic swing operator control panel, a
safety-designed four-layer protective operator door window and a standard air
filtration unit and overhead shower coolant.
The a71
comes standard with Makino's proprietary, next generation Geometric
Intelligence (GI) servo control with Radical Mode. GI with Radical Mode helps
provide the lowest cycle times achievable, while maintaining accuracy and
meeting the customer’s Cpk requirements.
Makino now offers three machine solutions to a customer base with diverse
needs:
