Main advantages:

- The CORMAK 660 x 4000 (C6266/4000) universal lathe can be used for many tasks, such as turning of internal and external surfaces, cones, polishing, metric, inch modular and DP threading, drilling and broaching.

- Solid cast iron bed construction ensures maximum vibration reduction. Additionally, the bed is hardened and precisely ground. The device bed is extremely resistant to twisting and does not vibrate, which meets the basic requirement for accurate turning.

- Central feed switching system , lead screw and feed shaft for threading
- Digital reading operates in (3) three axes of movement: longitudinal, transverse, upper slide. The processed electronic signal from the optical rulers visualizes the obtained values from movements along the axis on a digital screen.

- The lathe is equipped with a high-quality, reinforced spindle bearing system. Modern bearing of the main spindle with ball bearings
- Optimal work results are ensured by a large spindle bore of 105 mm , center spacing of 4000 mm , 3-jaw lathe chuck of 315 mm , and a powerful 7.5 kW engine.

- The rapid longitudinal and transverse feed system significantly reduces machining time and increases productivity.
- Hardened and ground gears in the spindle gear - ensures long-term operation stability.
- Equipped with a lead screw and a lead shaft for thread turning, automatic longitudinal and transverse feed.
- Easy adjustment of spindle speed and automatic feed from the ergonomic control panel on the gear.
- Possibility of machining a large range of threads without having to replace the shift wheels on the guitar. A wide range of turned threads: metric 0.2-14 mm (47 pcs) , inch 2-112 TPI (60 pcs) , modular 0.1-7M.P. (39 pcs.) , thread DP 4-112 DP (50 pcs.) Turning right and left threads.
- Thread turning clock designed for accurate counting of threads. The time-saving feature allows you to unscrew the lead screw nut in a few passes to quickly manually return the bottom bracket to its original position.
- The bed has a replaceable bridge for turning larger elements, e.g. a disc. This lathe model allows machining with a maximum diameter of 885 mm with the bridge removed.
