Metal lathe, Knuth Servoturn 500/1000

Metal lathe, Knuth Servoturn 500/1000

Manufacturer: Knuth, Germany

Servoturn series universal machine tool, made by combining two main features, the most modern technology feed system and classic mechanical engineering. High-torque servo motors that implement every feed movement with the dynamics of modern CNC machines. In addition to gearing rollers and gears, feed and thread pitch can be electronically controlled. Fast traversing on all axes minimizes downtime, and electronic stops provide ultra-precise accuracy.

• Servo motor feed system.
• Installed ball screws on each axle.
• Electronic adjustment wheels.
• Position indicator with constant V characteristic.
• Quick change tool locking head.

More detailed description:

• The tried and tested machine base foundation with the most advanced feed technology gives the machine much higher efficiency and a more attractive approach to it with servo motor drives.
• Well-known intuitive control, as in conventional machines, only much more advanced and convenient.
• Selection of feed and thread pitch using a rotary switch is a very convenient concept.
• Stops can be set electronically at the touch of a button.
• The feed is fully adjustable by means of a control potentiometer, finally adapted to conventional machines.
• Micro-precision control using electronic control wheels, but control is as simple as controlling a conventional machine tool.
• The axes of modern CNC machines are controlled by high-quality servo motors, which turn hand movements into extremely precise and dynamic ones.
• Unlimited selection of speeds and instantly available cutting speed at the tip.
• Instantaneous cutting speed: as the workpiece rotates, the spindle speed automatically adapts to the changing diameter of the workpiece - instantaneous cutting speed at the cutting edge ensures flawless results, and in terms of quality, it is not far behind CNC machines.

Device frame:

• The base of the machine with a strong, angular structure, with a wide, hardened construction track and V-shaped blocks allows for large-scale production processing.
• The head and main shaft are designed for optimal stability, vibration damping and temperature balance.
• The entire series also features a large shaft diameter.
• A quick-change nozzle assembly is included as standard for maximum flexibility and productivity.

Submission:

• Thanks to the ball nuts on X and Z, significantly less error due to clearance (backlash) is achieved, resulting in significantly higher accuracy.

Equipment:

• The device requires little maintenance and is equipped with a central lubrication system.
• The strong rear support (horseshoe) is easy to control and has a high compression force.
• Including 3-axis position indicators with integrated spindle rotation display, fully ready for operation.
• The Servoturn 500 comes with a WB quick-change tool holder as standard, while the Servoturn 660 model has a larger WC type tool holder.
