Knuth 1.3HP 11” LabTurn 2028 CNC Inclined Bed Lathe 181625

Description

The LabTurn is suitable for CNC training as well as for the production of small workpieces. The compact and mobile CNC lathe represents the full range of functions of a large production machine. The 8-station tool turret has four tools each for internal and external machining and long workpieces can be machined with a tailstock. The main spindle rotates continuously up to 3000 revolutions and the 3-jaw chuck has a diameter of 100 mm (3.9 in). With its simple, intuitive operator guidance, the Siemens 808 controller is the ideal introduction to CNC applications.

Siemens 808D Advance Control

• SINUMERIK 808D ADVANCE -- the perfect solution for modern standard machines
• CNC and drive communicate via a high-speed bus to ensure efficient positioning control plus high precision and optimum cutting performance
• This is topped by a guaranteed superior price/performance ratio
• This globally leading CNC technology provides high performance and power for the control of standard lathes
• In combination with a new generation of spindle and axis drives, the SINUMERIK 808D ADVANCE with 8.4" LCD provides an innovative ready-to-use digital CNC solution for modern standard machines
• Advantages - Digital solution provides higher precision:
  • Increased overload capacity supports a faster acceleration and deceleration of machine tools
  • Constant cutting speeds result in an increased surface quality of the workpiece
• Increased ruggedness:
  • During heavy machining operations, an automatic spindle torque adjustment will help protect machining tools and spindle systems.
  • The SINAMICS features a wide voltage range to prevent machine shut-downs during poor voltage supply conditions. This will significantly reduce machine down-times.
• Increased operator comfort:
  • A fast Ethernet connection facilitates easy start-up and diagnostics of machine tools and simplifies NC program use
