We are delighted to present the GT-7, an affordable option for a variety of uses on gang tool lathes. This machine is a versatile, flexible, and reliable addition to your company’s manufacturing capabilities. Our single-piece heavy casting is the culmination of years of experience in machine tool manufacturing and offers the best features for gang-tool and turret-lathe construction. These machines are ideal for dedicated production applications. We can add parts catchers, chip conveyors, and autoloading systems to maximize the machine’s usefulness. We have also developed post-processors for the GSK controls in Autodesk’s cloud-based CAM software, Fusion 360, to address the programming challenges of this type of 5-axis work.
CNC New, Inc. machines provide speed, power, and accuracy in a very compact footprint. All the electrical components are of the highest-grade hardened CNC controls developed for machine tools. This 5-axis system uses GSK CNC controls to perform indexing and interpolation functions via an integrated C-axis. Servo-driven spindle motors and drives have much greater low rpm torque and rapid duty cycles than vector-type spindle motors and drives.
CNC New, Inc. provides sales, service, and support for the products we manufacture. All electronic components, including cables and motors are provided by our single-source supplier. Spare parts are available from our Southern California facility, and we can provide prompt support, service, and parts for the life of your machine.
The GT-7 tool holders are high-precision Swiss tool holders that can utilize 1” bore tools that provide rigidity and flexibility not previously available with gang tool-designed machines. The GT-7 is the ideal platform for adding vibratory bowl feeder systems, gravity feed systems, and track loaders. We are also offering the first affordable robotic arm-loading system built by GSK. A compact design, combined with large ball screws and axis servomotors, results in a very robust machine system..
