Setting new standards with conventional lathes featuring large centre widths:

• Feed and thread leads can be selected via rotary switch - what a brilliant concept
• Heavy, large machine beds made of high-strength mineral-casting
• SERVOTURN® integrates many years of experience and superior construction properties, allowing uninterrupted cuts with high grade surface quality even under highest loads
• Stops can be set electronically with the press of a button
• Feeds are infinitely variable between 50 and 100% via override potentiometer - finally available on a conventional lathe
• Long turning length can be machined with highest precision due to the superior thermal stability and damping properties of this machine
• Micro-control via electronic hand-wheels - but handling and postioning just as with a conventional machine
• Axes are powered by high-quality servo drives that translate your hand movements with the precision and dynamics of modern CNC machines
• Infinitely variable speed adjustment and constant cutting speed of headstock

The definition of a new standard for conventional lathes had to be perfect - therefore, we complemented the Servoturn with the following features:

• The extensive Servoturn® series offers the same performance and features as servo-conventional precision machines
• All major controls are located for optimum accessibility or are intuitively linked to their respective functions
• A powerful main spindle drive with infinitely variable speed allows machining with constant cutting speed
• Feed and thread leads are selected electronically via a rotary switch, and executed by servo-motors featuring maximum precision and dynamics
• Quick-action tool holder included

Mineral-Casting Machine Frame

• Mineral-casting reduces vibration 6 times faster than cast-iron (GG25) and up to 10 times faster than steel- this ensures excellent surface quality that could not be achieved with conventional machines
• Excellent thermal stability
• Modern manufacturing process with excellent energy footprint

Linear Profile Guide Rails

• Maximum reliability and performance
• Excellent rigidity, strength and accuracy is achieved by optimum load distribution, designed for accepting high loads and torques
• No stick-slip effect
• Long life and minimum maintenance
• Replaceable parts

Recirculating Ball Screw

• Considerably less errors due to looseness (backlash), resulting in significantly higher precision
• Significantly reduced friction
• No stick-slip effect
• Reduced heat development
• Less wear for even less maintenance requirements

3-axis position indicator

• More accuracy
• Lower error rate
• Increased productivity
• Resulting in valuable time savings
• For increased productivity
• Easy to read display
• Operator-specific features
• Convenient keyboard layout
• Resolution: 0.01/ 0.005 mm
• Default coordinates
• Axis position is maintained when display is turned off
• Storage for 10 tools
• Radius / diameter toggle
• mm/inch conversion
• Display for top (Z0) and box way slide (Z1) both separate and in differential / cumulative mode for lathes
