CORMAK GOLIAT 660X4000

Main advantages:
- The CORMAK GOLIAT 660 x 4000 universal lathe can be used for many tasks, such as turning internal and external surfaces, cones, polishing, metric, inch modular and DP threading, drilling and broaching.
- The 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 is the basic condition for precise turning.
- Central feed switching system, lead screw and feed shaft for threading
- The digital readout works 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 axes on the digital screen.
- The lathe is equipped with a high-quality, reinforced spindle bearing system. Modern main spindle bearing with ball bearings
- Optimal work results are ensured by a large spindle passage of 105 mm, a 4000 mm center spacing, a 3-jaw lathe chuck of 320 mm, and a powerful 7.5 kW engine.
- The rapid longitudinal and transverse feed system significantly shortens the machining time and increases productivity.
- Hardened and ground gears in the spindle gear - ensures long-term stability of work.
- Equipped with a lead screw and a feed shaft for threading, automatic longitudinal and transverse feed.
- Easy adjustment of the spindle speed and automatic feed from the ergonomic control panel on the gear.
- Possibility of machining a wide range of threads without the need to replace the change wheels in the guitar. Wide range of threads: metric (22) 1 - 14 mm, inch (25) 2-28 T.P.I, modular (18) 0.5-7 M.P., D.P. thread (24) 4-56 D.P. Turning right and left threads.
- Thread turning clock designed for accurate counting of turns. The function is to save time so that in several passes you can unscrew the lead screw nut to manually quickly return the support to its original position.
- The bed has a replaceable bridge for turning larger elements, e.g. a disc. This lathe model allows for machining with a maximum diameter of 870 mm with the bridge removed.
