Control Systems
The GTV Series is equipped with the FANUC 0i-TF control system, which is renowned for its reliability and user-friendly interface, enabling operators to easily manage complex machining operations while benefiting from FANUC’s reputation as a technological leader that provides exceptional technical support; moreover, Cubic Machinery has collaborated closely with FANUC to meticulously tune the servo and spindle motors, resulting in a remarkably fast C-axis response rate and impressive spindle and linear axis acceleration that enhance overall machining efficiency and performance.
Work Holding
Cubic Machinery offers a versatile range of work holding options for the GTV Series, including collet spindle noses in the widely used 5C and 16C configurations that ensure high accuracy during chucking operations, while also providing a dead-length B42 (DIN6343 173E-type) collet chuck which features a design that eliminates any z-axis movement and prevents workpiece pull-back when the collet is closed, thereby enhancing precision and stability during machining; in addition to collets, operators can utilize A2-4 or A2-5 3-jaw or 4-jaw chucks to configure the GTV for various chucker operations, and the hydraulically actuated chuck system significantly outperforms traditional air chucking by delivering a stronger gripping force that facilitates heavier cuts and improves overall machining capabilities.

These industries benefit from the speed, rigidity, and precision that the GTV-27L and GTV-42L provide, resulting in higher productivity and product quality.
What are the key features of the GTV-27L and GTV-42L lathes?
The GTV-27L and GTV-42L lathes are known for their extreme level of accuracy, maintaining a positioning accuracy of 0.00005 inches even at maximum traverse speeds, which ensures high precision in machining operations. They also feature rapid traverse rates of 787 inches per minute on the X and Z axes, which significantly reduces non-cutting time and enhances productivity. Additionally, the unique vertical plate design of these lathes allows metal chips and coolant to drop directly downward, away from the cutting tools, improving parts production efficiency and cooling effectiveness.
How do the GTV-27L and GTV-42L lathes handle work holding?
These lathes provide a wide range of work holding options, including collet spindle noses in the widely available 5C and 16C configurations for high accuracy chucking. They also offer a dead-length B42 (DIN6343 173E-type) collet chuck, which eliminates workpiece pull-back by having zero z-axis movement when the collet is closed. Furthermore, the hydraulically actuated chuck on these machines provides a stronger gripping force than air chucking, allowing for heavier cuts and improved machining stability.
How do these lathes integrate with automation systems?
The GTV-27L and GTV-42L lathes can be integrated with automation systems, such as cobots, to enhance production efficiency. For instance, a setup involving a Cubic GTV-27 machine and two GTV-42 lathes with UR5e cobot arms was implemented to maintain high throughput and accuracy while minimizing the machine’s footprint. This integration allows for consistent programming with machine controls and efficient use of space, making it ideal for operations requiring high precision and flexibility.
