Universal lathe CORMAK GRAND 420x1500

Main advantages:

• GRAND 420x1000 lathe has combined cast iron bed (right and left bases made of cast iron) for maximum reduction vibrations. Additionally guides bed precisely ground, hardened.
• The digital readout works in 2 (two) axes of the longitudinal and transverse movement of the carriage. The processed electronic signal from the optical rulers visualizes the obtained values from the movements along the axis on a digital screen.
• The lathe is equipped with a high-quality and reinforced spindle bearing system.
• Optimum work results provides a large spindle bore 55 mm, 3-jaw 200 mm lathe chuck, and a powerful motor dual band 2.0/2.4 kW.
• Hardened and ground gears in the spindle gear.
• The appropriate bed width of 220 mm ensures stable and precise working conditions.
• Equipped with lead screw and lead shaft for threading and automatic longitudinal and transverse feed.
• Easy adjustment of the spindle speed and automatic feed from the ergonomic control panel to the gears. Feed selection lock by lead screw or shaft.
• Adjustable overload clutch on the drive shaft.
• A large range of threads can be machined without having to replace the shift wheels in the guitar. Wide range of threads turned: metric (26) 0.4 - 7 mm, inch (34) 4-56 T.P.I. Turning right and left hand threads.
• Thread turning clock designed for accurate counting of threads. The function is to save time so that in a few passes you can unscrew the nut of the lead screw and manually and quickly return the slide to its original position.
• Central feed gear, lead screw and thread feed shaft
• The bed of the lathe is extremely torsion-resistant and does not vibrate, thus meeting the basic requirement for accurate turning.

In addition, the set includes a set of 20 x 20 mm knives 7 pieces and a MK4 rotary point
