Cormak Goliath 660 x 2000YB Universal Manual Lathe

Cormak Goliath 660 x 2000 Universal Manual Lathe

Machine Type: Manual Universal Lathe

Machine Description

The CORMAK 660x2000YB lathe is an advanced tool designed for industrial production of single parts, where precision and quality of machining play a key role. This model is perfect for machining large and medium-sized parts, offering exceptional stability and accuracy, which are essential in machine production with high technological requirements.

The slow-speed operation of the machine allows for more precise production of details, reducing the risk of vibration and ensuring a smooth surface finish.

The CORMAK 660 x 2000 (CJ6266YB/2000) universal lathe is a versatile machine that provides exceptional precision in slow-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 slow speed of this lathe makes it an excellent choice for jobs that require maximum accuracy and stability.

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 vibrations, enabling precise turning even at the lowest rotational speeds.

Advanced Features

• The central feed switching system , including the feed screw and feed shaft , allows for efficient threading, even at low rotational speeds.
• Accelerated longitudinal and cross feeds are easily controlled using the joystick, facilitating precise machining, especially at low speeds.
• Three-axis digital readout (longitudinal, cross and upper slide) with on-screen display allows precise control of every lathe movement, especially during slow-speed operations.
• High-quality bearing system with ball bearings and 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 pace. The rapid longitudinal and transverse feed system significantly shortens the machining time, but also allows for precise execution of details at low speeds.

Additional features

• Hardened and ground gears in the spindle gearbox ensure durability and stability of operation for a long time, even at low speed.
• Ergonomic adjustment of the spindle speed and automatic feed allows precise adjustment of machining parameters.
• The thread turning clock allows for accurate counting of threads, which saves time and allows the carriage to return to its original position more quickly.
• The replaceable bed bridge allows the machining of larger workpieces, e.g. discs, up to a maximum diameter of 900 mm with the bridge removed.

The CORMAK 660 x 2000 lathe is a reliable machine that, thanks to its slow-speed operation and solid construction, is suitable for precise and demanding machining operations. It is an ideal choice for a wide range of lathe tasks, ensuring high quality and accuracy of machining.
