FAQ

GTV Series Questions

Answers to common questions about the GTV Series.

The GTV Series Gang Tool Lathes are ideal for industries that require high precision and intricate component production. These include aerospace, automotive, and medical industries, where the ability to produce complex parts with speed and accuracy is critical.  The machines' capabilities make them a cost-effective solution for manufacturers in these sectors.

The GTV Series Gang Tool Lathes are renowned for their extreme accuracy, maintaining a positioning accuracy of 0.00005 inches even at maximum traverse speeds. This precision is essential for high-quality machining tasks. The machines also feature rapid movements of 787 inches per minute on the X and Z axes, which minimizes non-cutting time and enhances productivity. Additionally, the unique vertical plate design of the GTV Series allows metal chips and coolant to drop directly downward, improving cooling efficiency and facilitating faster parts production

Gang tool setups offer several advantages over traditional turret-based solutions. They provide higher rigidity and positional accuracy, which are crucial for precise machining operations. Moreover, gang tools enable faster tool changes, reducing cycle times and increasing overall productivity. These features make gang tool CNC machines particularly suitable for high-precision manufacturing environments, such as aerospace, automotive, and medical industries, where tight tolerances and complex parts are common.

The GTV Series offers both FANUC 0i-TF and FAGOR 8055iTB controls, providing users with reliable and robust technical support. FANUC, in particular, is known for its technological leadership and unsurpassed reliability, making it a preferred choice for many manufacturers.
