We are delighted to present the Mini-Max (GT-30) and other models of gang tool lathes that are the affordable option for a variety of gang tool lathes. Call for special introductory pricing. These machine models are a versatile, flexible, and reliable addition to your company's manufacturing capabilities. These machines are ideal for dedicated production applications. We can add part catchers, chip conveyors, and autoloading systems to maximize the machines' usefulness. We have also developed post processors for the GSK controls in Autodesk’s cloud product Fusion 360 CAM software to solve the programming challenges involved with this type of 5-axis work.

The Mini-Max (GT-30) is a flatbed design gang lathe with a footprint 52” long and 44” wide. This small footprint lathe has a servo C-axis spindle motor and can deliver rapid duty cycles. The electrical component suppliers provide the highest-grade hardened CNC controls, liquid-tight motor cables that are available for machine tool manufacturers. This 5-axis system is from GSK CNC systems with the capability to perform indexing and interpolation functions through the use of 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.
