CORMAK GOLIAT 660X2000YB WOLNE OBROTY

The CORMAK 660 x 2000 (CJ6266YB/2000) universal lathe is a versatile machine tool offering exceptional precision for low-speed turning of various materials. It is ideal for machining both internal and external surfaces, taper turning, polishing, threading (metric, inch, module, and DP), as well as drilling and broaching operations.

Thanks to its low spindle speeds, this lathe is an excellent choice for tasks requiring maximum accuracy and operational stability.

Robust Construction

The lathe bed is made from high-quality cast iron, effectively damping vibrations—crucial for low-speed operations. The bed is hardened and finely ground, providing outstanding resistance to twisting and vibrations, which enables precise turning even at the lowest spindle speeds.

Advanced Features

- Centralized feed switching system, including a leadscrew and feed shaft, allows efficient threading, even at low spindle speeds.
- Longitudinal and cross rapid feeds are easily controlled via joystick, facilitating precise machining, especially at reduced speeds.
- Three-axis digital readout (longitudinal, cross, and compound slide) with a screen display offers strict control over all lathe movements, essential for slow-speed operations.
- High-quality bearing system with ball bearings and modern spindle bearing arrangement ensures stable and safe lathe operation.

Performance and Precision

With a large spindle bore (82 mm), a centre distance of 2000 mm, a 3-jaw chuck (315 mm), and a powerful 7.5 kW motor, the CORMAK lathe guarantees efficient machining, even at slow speeds. The longitudinal and cross rapid feed system significantly reduces machining times while allowing precise operations at low rotational speeds.
