CORMAK GOLIAT 660X4000

Industrial Universal Lathe CORMAK GOLIAT 660 × 4000 mm

The CORMAK GOLIAT 660 × 4000 is a heavy-duty industrial universal lathe designed for demanding turning applications. With a 4000 mm distance between centers and a 105 mm spindle bore, the machine enables precise machining of large-size components while maintaining high rigidity and accuracy. It is an ideal solution for production plants, repair workshops, and companies specializing in the regeneration of machine parts.

Main Features of the Machine
4000 mm distance between centers and 3950 mm turning length – designed for machining long shafts, pipes, and large components.
Large 105 mm spindle bore – enables efficient machining of large-diameter workpieces.
Heavy-duty cast iron bed – hardened and precisely ground, providing excellent resistance to twisting, vibration, and deformation.
3-axis digital readout system – ensures accurate control of carriage and slide positions.
High-quality spindle bearings – guarantee smooth operation, stability, and long-term precision.
Rapid feed system – longitudinal rapid feed of 4.5 m/min and cross rapid feed of 1.9 m/min significantly reduce machining time.
Removable bed gap section – allows turning of oversized components with diameters up to 870 mm.
Direct thread selection – enables quick adjustment of threading parameters without changing change gears.
