Machine Bed -
The one-piece heavy-duty machine bed and base casting is made of a high-density Meehanite processed cast iron
structure that is heavily ribbed to increase lateral stiffness and maximize stress absorption during the turning
process. The torque-tube casting is perfectly symmetrical to ensure that no twisting occurs in the bed during heavy
cutting or as a result of thermal migration. The low center of gravity cast bed weighs over 3000 pounds and the
design gives superb vibration control, which provides for superior surface finish and increased tool life. The
assembled machine weighs over 3,980 pounds making it the heaviest machine in its class.
Machine Axis –
The CYCLONE GT features two separate axis that are not stacked one upon another like most other CNC lathes,
where the X-axis rides on top of the Z-axis. The X-axis is the separate single cross motion axis of the tool table. The
Z-axis is the single longitudinal headstock axis. This unique separate axis configuration provides a tremendous
improvement in machine accuracy, rigidity, tool life, surface finish, as well as metal removal capability.
Machine Ways -
Both the X and Z axis utilize heavy-duty linear ways made in Japan by the prestigious THK company to ensure
sustained high accuracy machining results. The faster rapid traverse rates reduce non-cutting time and the low
stick/slip characteristics of the THK linear way design ensure superior complex workpiece shape definition due to the
axes ability to follow the control contour commands more precisely.
Ballscrews -
Premium quality 25mm diameter double-nut NSK ballscrews are utilized to ensure high accuracy and long service
life. The ballscrew nuts are preloaded and forced lubricated and are laser aligned during machine assembly. The
ballscrew rotational torque is checked over the entire travel length to ensure there is no binding in the assembly to
minimize any wear or thermal migration that would adversely affect machine accuracy.
Brushless Axis Motors -
The axis motors are high-performance Mitsubishi MEL-PRO Brushless AC servo motors that provide for less wear
and are totally enclosed to ensure no dust or damage to the motor for increased reliability. This Brushless AC motor
design improves productivity by accepting higher voltages and increased current for faster acceleration and
deceleration. All Mitsubishi MEL-PRO motor amplifiers are contained in a separate electrical enclosure that has its
own heat exchanger to maintain the appropriate operating temperature.
Machine Spindle -
The machine spindle is supported in two matched-sets of high quality NSK Class-7 (P4) bearings, which are
lubricated for life. The spindle is dynamically balanced to eliminate vibration for better surface finish and workpiece
accuracy. This extra attention to detail in assembly produces a spindle that generates less heat and maintains a
longer operational service life. Every spindle is put through a 72-hour test run prior to assembly that records any
thermal gradients or spindle vibration. This process ensures many years of trouble-free production usage. The
spindle is driven by a multi-ribbed offset drive belt to enhance the cutting torque power range for more efficient metal
removal over a wide range of spindle speeds.
Spindle Motor -
The spindle is driven by a highly reliable Mitsubishi MEL-PRO series motor designed specifically for heavy-duty
machine tool applications. The motor is balanced within 5-microns to provide state-of-the-art surface finishes. The
motor is designed with less rotor inertia that standard induction motors and features a large diameter output shaft
and heavy-duty radial load bearings for a long service life. This means faster acceleration/deceleration rates and
reduced cycle time for increased productivity. The Mitsubishi MEL-PRO series motor is matched to a Mitsubishi MEL-
PRO servo amplifier module which maintains a constant variable current to the motor ensuring high reliability and
accuracy in angular positioning for superior thread start positioning, engraving, and other live tool machining
applications where accurate angularity is required. The motor amplifier is mounted in a heat exchanger enclosure to
ensure that temperature regulation is maintained for long-term reliability.
Automatic Lubrication System –
The automatic lubrication system operates on a timed interval and monitors low oil level, low pressure, and tests the
system for any broken lube line. Any lube alarm will stop the machine at the end of the current cycle if a fault
condition occurs. The lube system is housed in a recess in the casting to ensure that it cannot be damaged by any
passing shear hazard. A meter valve regulates oil flow, which is pumped at timed intervals through nylon tubes to
meter values on the ways and ballscrews.
