High Performance CNC LATHES

TURNING CENTERS

• Rigid Precise linear guideways ensure the longevity and performance of each and every machine.

• Increased rapid travel speed improves cutting efficiency.

• The highly rigid servo driven turret provides heavy duty cutting capability.

• The full enclosure design prevents the chips and coolant from splashing providing a safe and clean working environment.

• The auto oil lubrication system provides rails, ballscrews and key units precise and adjustable oil volume control

High Performance CNC LATHES

• The main machine body is designed as a one-piece cast construction. The 30-degree slant bed provides the spindle head, turret and tail stock with an excellent supporting base with low gravity.

• Enhanced rib design in the major construction areas provides extra rigidity for heavy duty or high speed cutting. This added rigidity also prolongs the cutting tool service life.

• The major construction elements are made using FC30 Meehanite cast iron, which is a very stable precision-proven structure.

• The X and Z axes are driven by absolute AC servo motors. This high torque/high power motor provides fast acceleration and deceleration movement while the absolute encoder technology eliminates the usage of a limit switch. The home position operation is no longer needed when the machine is first powered up.

High Rigidity, High AccuracyCONSTRUCTION DESIGN

Collision Protection Device• The machine is equipped with an axis collision protec-

tion device which can absorb and reduce the collision force. Machine accuracy is maintained if any axis malfunction occurs

• The X and Z axes uses heavy duty linear guideways to ensure high rigidity low noise and low friction machining to achieve high speed feederates and contour cutting accuracy.

High Speed & High Accuracy Linear Guide Ways• The zero backlash linear guideway ensures consis-

tent cutting service during curve or slope cutting.

• Suitable for high speed travel and helps to minimize power consumption.

• The linear guides’ rolling contact instead of sliding contact, reduces friction loss and increases posi-tioning accuracy.

• Loading capacity and rigidity is excellent for multiple direction cutting.

• The roller type linear guideways high durability guar-antees long service life and high accuracy.

High AccuracyTRANSMISSION SYSTEM

• High speed feedrates are 787 ”/min in X-axis and 945 ”/min in Z-axis.

• A direct drive coupler is used to link the servo motors and high precision ball screws in both the X and Z-axes.

• The auto-lube system provides the proper lubrication to both the ball screws and their support

bearings providing long life and high precision.

• Extremely large C3 grade ball screws are used for both high rigidity and high precision.

Spindle System• Super precision P4 grade spindle bearings are

arranged with an optimized span to maximize sta-bility and ensure extreme cutting accuracy over a long service life.

• The spindle bearing arrangement: double row

roller bearing x 1 and angular ball bearings x 2 at the front side; and double row roller bearing x 1 at the rear side to provide maximum support.

Spindle Power Transmission System• A high-performance V-belt drive is used for power

transmission. A belt drive reduces maintenance and the heat generated by a gear type drive. Using the pulley’s gear ratio, maximum spindle torque can be obtained and the maximum cutting capacity is achieved.

• Rigid tapping capability is standard on the machine. Setting up the threading operation is easy providing high accuracy while achieving maximum product output.

• The spindle can be orientated and stopped at multiple positions. This is handy for any specific angle operation, as well as for the manual workpiece loading/unloading.

Heat Emission System• The thermal fin design is standard on the

spindle head. The generated heat is effi-ciently removed by circulating air around the head.

Servo Turret• The robust turret is driven by a servo motor providing

adjacent tool to tool time of 0.9 seconds and opposite tool change time of 2.0 seconds.

• A large turret shaft is used for its high rigidity and high positioning accuracy. The turret rigidity ensures cutting capability for a wide variety of applications.

• There is no interference between the maximum inner tool and the chuck or workpiece when the turret is fully loaded.

Tail Stock Unit• The high accuracy tail stock provides high

rigidity and loading durability. The move-ment of the tail stock quill is programmable with hydraulically adjustable thrust force.

Separated Coolant Tank System• The isolated coolant tank is designed for easy for maintenance.

The high pressure pump and large coolant flow can efficiently remove the heat generated by the machining process.

• The chip conveyer system is located under the front side of the machine. This sys-tem can easily remove the large volume of chips generated by the turning process.
