KITAGAWA GT Series NC Rotary Table
Made in Japan
Manufacturer: Kitagawa
Model: GT Series
Feature:
NC rotary table suitable for heavy machining
The very strong clamping torque was achieved by increased piston area and new clamping mechanism.
High clamping torque and rigid body allows heavy machining and shorter tact time.
Built-in rotary joint available
