Kitagawa GT Series NC Rotary Table
Manufacturer: Kitagawa Corporation.
Model: GT Series
Feature:
The NC rotary table is perfect for heavy machining tasks. It delivers very strong clamping torque. This is possible because the piston area is larger. Moreover, the new clamping mechanism boosts clamping power even more.
As a result, the NC rotary table offers stable and reliable performance. In addition, the rigid body structure supports heavy-duty cutting. Therefore, you can achieve faster machining and shorter tact time.
Furthermore, the NC rotary table includes a built-in rotary joint. This makes setup easier and more flexible.
Finally, CE-compliant models of the NC rotary table are available. These models meet safety and international standards.
