Universal lathe 660x2000

CORMAK GOLIAT 660X2000YB WOLNE OBROTY

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

The low speed of this lathe makes it an excellent choice for tasks requiring maximum accuracy and stability of work.
Solid construction

The lathe bed is made of high-quality cast iron, which effectively dampens vibrations, which is crucial for low-speed operation of the machine. Thanks to the hardened and precisely ground bed, the lathe provides exceptional resistance to torsion and vibration, enabling precise turning even at the lowest rotational speeds.
Advanced features

The central feed switching system, including the lead screw and feed shaft, allows for efficient threading, even at low speeds.
The accelerated longitudinal and cross feed can be easily controlled by the joystick, which facilitates precise machining, especially at low speeds.
The digital readout in three axes (longitudinal, cross and upper slide) with an on-screen display allows for precise control over every movement of the lathe, especially during slow-speed operations.
The high-quality bearing system with ball bearings and the modern bearing of the main spindle ensure stable and safe operation of the lathe.

Efficiency and precision

Thanks to the large spindle passage (82 mm), center spacing (2000 mm), 3-jaw lathe chuck (315 mm) and a powerful 7.5 kW engine, the CORMAK lathe guarantees high machining efficiency, even at a slow work pace. The rapid longitudinal and transverse feed system significantly shortens the machining time, but also allows for precise execution of details at low speeds.
