Suitable for high-speed machining of die cast aluminum parts, as
well as near net shape, or precision steel castings for the automobile
industry, office automation, medical, optical and aircraft industries.
It utilizes a three-axis traveling structure with a fixed table
that allows the machine to be used as a stand alone universal machine,
or in flexible transfer lines. As a stand-alone machine it has a
180-degree rotary type high-speed APC equipped with a 90 degree
4th axis NC turn table at the loading pallet. In accordance with
the high speed and high productivity features, a hydraulic source
can be easily provided for each pallet, for quick connection to
hydraulic fixtures. To assist high speed machining, coolant through
the spindle is provided as a standard feature.
A 12,000 RPM wide range, 5 horsepower spindle motor provides optimum
speed for high speed machining. Spindle bearing ID realizes a large
size of 1.97" with high rigidity.
Quick response, heavy duty axis drives and zero clearance, no resistance
linear motion guide way systems, allow all 3-axes feed rates and
rapid traverse rates of 1,970 inches per minute. Feeds and travels
such as these are required for optimum metal removal on near net
shape and non-ferrous parts.
4.0 second chip-to-chip arm-less automatic tool change times get
the cutters to the workpiece in the shortest time to allow minimum
out-of-cut non-productive time.
The new 180 degree rotary pallet changer moves the pallet from the
load station to the action station in only 6.9 seconds, again minimizing
the out-of-cut time. The loading station also rotates to allow access
to all sides of the pallet to expedite loading and unloading. The
standard 0.001 degree table index time for a 90 degree index has
been reduced to only 2.0 seconds.
The hydraulic, pneumatic and lubrication controls are collectively
arranged in the back to realize space saving and efficient maintenance
work.
