CORMAK GOLIAT 800x4000

GOLIAT 800 × 4000 Universal Lathe (CJ6280YC/4000)
Product Features
Heavy-duty cast iron bed provides maximum vibration damping. The bed is hardened and precision-ground, offering exceptional rigidity and resistance to twisting, ensuring the high accuracy required for precision turning.
Centralized feed gearbox with lead screw and feed rod for threading operations.
3-axis Digital Readout (DRO) displays longitudinal, cross, and compound slide movement. Electronic signals from the optical scales are processed and displayed on the digital readout for accurate positioning.
Equipped with a high-quality reinforced spindle bearing system featuring modern precision ball bearings for smooth operation and extended service life.
Excellent machining performance thanks to a 105 mm spindle bore, 4,000 mm distance between centers, 315 mm 3-jaw chuck, 400 mm bed width, and a powerful 7.5 kW main motor.
Rapid longitudinal and cross feed significantly reduces machining time and increases productivity.
Hardened and ground gears in the spindle gearbox ensure long-term reliability and smooth operation.
Equipped with both a lead screw and feed rod for thread cutting as well as automatic longitudinal and cross feeding.
Convenient spindle speed and feed rate adjustment from the ergonomically designed gearbox control panel.
Thread chasing dial enables precise thread synchronization, allowing the half nut to be disengaged between passes and the carriage to be returned quickly by hand, reducing threading time.
The machine bed features a removable gap section, allowing machining of larger workpieces such as discs. With the gap removed, the lathe can machine workpieces up to 1,000 mm in diameter.
