CORMAK GOLIAT 800x4000

The CORMAK GOLIAT 800 × 4000 (CJ6280YC/4000)

Main Advantages
Versatile machining capabilities – the GOLIAT 800 × 4000 enables external and internal turning, taper turning, polishing, metric, imperial, module and DP threading, drilling, and broaching operations.
Heavy-duty cast iron bed construction – provides maximum vibration damping. The bed is hardened and precisely ground, ensuring excellent torsional rigidity, long service life, and machining accuracy.
Central feed control system – equipped with a lead screw and feed shaft for threading and automatic longitudinal and cross feeds.
3-axis digital readout system – displays precise position values for longitudinal movement, cross slide movement, and compound slide movement using optical scales and electronic signal processing.
High-quality spindle bearing system – reinforced spindle support with precision bearings ensures smooth operation and high machining stability.
High machining capacity – large spindle bore of 105 mm, center distance of 4000 mm, 315 mm 3-jaw chuck, 400 mm bed width, and a powerful 7.5 kW motor provide excellent performance for large workpieces.
Rapid longitudinal and cross feed system – significantly reduces machining time and improves productivity.
Hardened and ground spindle gears – ensure quiet operation, durability, and reliable power transmission.
Automatic feed and threading capability – the lead screw and feed shaft allow precise thread cutting and automatic feeds.
Ergonomic control panel – allows easy adjustment of spindle speeds and automatic feed parameters.
Threading dial indicator – enables accurate thread engagement and repeatable threading operations.
Removable bed gap section – allows machining of oversized components such as discs. With the gap removed, the machine can handle workpieces with a maximum diameter of 1000 mm.
