interesting facts about fanuc cnc
The FANUC CNC (computer numerical control) is known the world over for offering high efficiency
and high precision control servo motors. The ai series in particular is specifically designed for the
new generation of precise, high speed and compact machines; the ai series has the FANUC AC
servo motor, the FANUC AC spindle Motor and the FANUC Servo Amplifier in its offering. These
offerings ensure that each and every client's needs and requirements are not only met, but
ultimately surpassed.
The Nano control ensures that the servo motor offers very smooth rotation with quick acceleration
AC Servo motors to boot; these motors are thus suitable for axis feed purposes in most machine
tools. The motors come in compact sizes; this is enabled by the newly implemented structure
design thereby making the axial lengths of the motor shorter thereby downsizing the overall size
of the machine. The pulse coder is also compact and provides super high resolution of around
1,000,000/rev on standard speed and an option of 16,000,000/rev; all these contribute positively
towards making the machines more precise and compact too. Finally the servo motor is also more
intelligent and has an automatic identification functionality that can readily identify a motor or
pulse coder; this eases maintenance operations.
The high performance AC Spindle motor on the other hand is armed with really high power
availed at relatively high speeds; making them quite suitable for spindles used in machine tools.
These particular motors can be accelerated quickly to very high speeds; they further feature an
effective cooling structure and an optimum winding design. The built in spindle motor affords low
vibration, provides highly accurate service. There is also a direct connection to the machining
center that is provided through a center-through coolant in the AC spindle motor. One can opt for
either the oil or air cooled series of the motor.
The FANUC servo amplifier is relatively compact and functionally energy saving. The size has
been reduced by an average of 20% whereas the depth of the amplifier has been reduced by
11%; all these reductions are compared against previous models from the same manufacturer
and from the competition too. The amplifier uses the latest IPM technology in the market; this
allows the amplifier to reduce the rate of power loss by a whopping 10%. Maintenance is also
made a tad simpler by using the readily available motor thermal information and the unique ID;
the upkeep is aptly called smart maintenance.
The ultra smooth rotation is combined with the servo motor to provide users with really ultra
smooth servo feed, combine this with accurate current detection capabilities, the high resolution
and high response pulse coder and you have a real gem of a machine for any suitable machine.
There are also some enhancements on the stability front and current control. These FANUC CNC
machines also come with some high speed DSP packed with very advanced Control algorithm;
specifically the SPINDLE HRV control. The high response spindle control is made possible with
loop sampling time with faster velocity armed with a detector circuit with high resolution.
