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.
