Product description
Kitamura 7G – 5-axis vertical machining center
The Kitamura 7G is a 5-axis vertical machining center designed for high-precision applications, including the aerospace industry. The machine offers exceptional positioning accuracy of ±0.000079" and repeatability of ±0.000039", ensuring the highest precision in machining complex parts.
With full simultaneous machining capability on all five axes, the 7G guarantees maximum versatility and production efficiency. The machine is equipped with a gear-driven spindle capable of operating at speeds up to 12,000 rpm, ensuring high productivity and flexibility in machining a variety of materials.
All axes feature linear scaler feedback, ensuring precise control and repeatability. The robust Meehanite cast iron construction provides excellent vibration absorption, improving the surface quality of machined parts.
The machine is equipped with a 4/5-axis rotary table with zero backlash, enabling accurate machining at high operating speeds: 1,969 rpm in the X and Y axes and 1,181 rpm in the Z axis, which shortens cycle times and increases production efficiency.
