MAKINO HIGH TORQUE SPINDLE
MAKINO
HIGH-TORQUE SPINDLE
High-torque,
high-thrust integral drive spindle now available on three HMCs
MASON,
OH--January 2006--Makino’s unique, high-torque and high-thrust spindle is now available on
three different horizontal machining centers to provide unparalleled
productivity and reliability that helps customers reduce costs from their
manufacturing operations. The most powerful integral drive spindle on any
machine in the world, it has been expanded from its initial offering on the
Makino a81, which was renamed the Makino a81M. It is now also available on the
company’s A99E and A100 E horizontal machining centers.
The Makino
integral drive spindle greatly outperforms all other spindles on the market due
to the nature of its special design, which provides significantly higher torque
at a low rpm. The proprietary design of the integral drive spindle combines the
optimum blend of speed and superior rigidity necessary to take aggressive cuts.
Other high
torque spindles utilize a geared-type head. Such design intrinsically causes a
loss of significant power that further drops spindle efficiency, which can slow
down the spindle performance and adversely affect cycle times.
Visit Booth
# 8301 in Hall A of the South Building during the 2006 International Manufacturing
Technology Show (IMTS) at McCormick
Place in Chicago,
Illinois, September 6 through 13
to learn more about this and other technological innovations.
a81M
Features
The Makino a81M has a rapid feed rate of IPM 1.42 IPM (36m/min). It is
able to handle workloads of up to 10, 800 pounds (4,900Kg).
The
high-torque, integral drive spindle has an available 744 foot pounds (1,009 Nm)
of torque from zero to 392 rpm. To match that torque, the spindle employs
50 hp from 2,000 to 5,000 rpm. This duty rating and continuous output of the
Makino spindle lends itself to difficult cutting scenarios.
Long reach
and large diameter boring operations require a great deal of torque,
particularly at low rpm. For applications such as tapping, where a significant
amount of spindle stopping, starting and reversal occurs, the Makino
high-torque spindle is significantly faster and has less idle time.
With four
rows of angular center trough hinge conveyor bearings in the front and two rows
in the back, the a81M has a cartridge-style spindle with jacket cooling and
oil/air lubrication. This helps provide enhanced performance and
serviceability, and lower maintenance labor costs.
Application
and Markets
The a81 is well suited in large diameter rough boring and face milling on tough
and hard metals. These include tool steel, carbon steel, stainless steel,
titanium, titanium alloy, nickel-based alloys, inconel, cast or ductile
iron and CGI (compacted graphite iron).
The a81 has
significant application in general machining, production machining, aerospace,
diesel engine, construction equipment, and pump and compressor manufacturing.
The Makino high-torque, integral drive spindle employs a standard CAT 50-taper
toolholder, with an HSK-A100 as optional. Diameters range up to 4.75
inches (120 mm).
The
integral drive, high-torque spindle has no corresponding loss of acceleration
and deceleration. The acc/dec ranges from 4.4 seconds to 3.8 seconds at 8,000
rpm, ranging up to 10,000 RP
