GLS-200 Turning Center & GLS-200M (Live Tooling)

Designed with high speed performance and practicality in mind, the GLS series combines power, strength and speed to accomplish today's high speed turning applications. Features include 0.2 sec. indexing servo turrets with 12-staion (accepts 3/4" OD tooling) on 6" chuck models and 10-station (accepts 1" OD tooling) on 8" chuck model. The fast indexing and fast axes rapid traverse rates are critical in lowering cycle times. A 30 slant bed provides a rigid foundation plus smoother chip disposal and easier operator access for faster set-up times. The spindle is driven by a Fanuc 20 HP (Peak) motor with high speed bearings. A standard chip conveyor and separate coolant tank system further enhance production efficiency and operation convenience.

By designing heat-dispensing fins to the spindle housing, heat generated by high spindle speeds is dispensed quickly and efficiently. Heat distortion is eliminated to a minimum and additional strength is added to the structure. "NSK" P4 grade super high precision angular contact ball bearings are used to support the spindle. Three bearings in the front with two in the rear are positioned in best-suited distances of support. This bearing combination results in ultra-smooth high-speed turning and rigidity to withstand loads from all directions with a higher level of accuracy.

The precision direct belt drive system provides greater spindle control, flexibility and less noise. Other standard features include spindle orientation, which allows the spindle to stop at the desired programmed position, useful for broaching applications and manual part handling. Rigid tapping feature controls simultaneously the speed and position of the spindle. By synchronizing the Z-axis feed with the spindle RPM, rigid tapping provides high-speed precision tapping without the use of floating tap holders. Set-up is easier and depth of thread more accurate. Rigid tapping permits maximum productivity for tapping operations.

Fanuc a8 AC (Oi-TC controls) spindle motor generating 15 HP at 30 minutes and 20 HP at peak has torque ratings of 52 ft-lbs at 30 minutes and 70 ft-lbs at peak. The motor is fine tuned to match the maximum rpm of the spindle by pulley ratios to generate the best output possible.

YAMA SEIKI utilizes the latest in control technology from FANUC with a 32-bit microprocessor, the OiMate-TC and Oi-TC controls. These controls provide many features as standard that are not available or costly options found on other controls. Features such as rigid tapping, multiple repetitive cycles, direct programming, custom macro B, color LCD screen (Oi-TC only), 640M of program memory, graphics, and super-fast processor are standard plus many more.
