2SP1 motor spindles for SINAMICS S120 Siemens

Область применения



The main application area for 2SP1 motor spindles are main spindles for milling machines and machining centers in the job shop area of the machine tools sector.

The 2SP120 motor spindles are particularly suitable for the area of light metal machining at low torque and high speeds.

The 2SP125 motor spindles are characterized by a high torque. The main area of application is in the machining of steel and castings.

Обзор



The 2SP1 motor spindle product range is a compact standard motor spindles that can be used as an alternative to belt-driven spindles and can be used both for rough cutting and for precise fine machining.

The 2SP1 motor spindle contains all the classical elements of a motor spindle, such as a tool interface, tool clamping and release mechanism, spindle bearings suitable for absorbing the machining forces, water-cooled drive motor, spindle casing for fixing and sensors for indexing and monitoring tool changeover.

The motorized spindles are available in 2 diameters of 200 mm (7.87 in) (2SP120) and 250 mm (9.84 in) (2SP125) and are offered with different torque and speed graduations to match the respective milling machine family. The motor spindles are ideally matched to the performance levels of SINAMICS S120.

The complete product range of 2SP1 motor spindles was developed in cooperation with and is manufactured at Weiss Spindeltechnologie GmbH.

Дизайн



The 2SP1 motor spindles are characterized by a rugged design.

Depending on the version, the following options are available for 2SP1 motor spindles:

  • Various tool interfaces
  • Internal tool cooling
  • External tool cooling

Интеграция



The 2SP1 motor spindle can generally be used with:

  • SINAMICS S120
  • SINUMERIK 840D sl

A VPM Voltage Protection Module must be used with 2SP1 motor spindles in synchronous design.

Особенности



The 2SP1 motor spindles offer the user the following important advantages over conventional belt-driven solutions:

  • Compact spindle solution and "everything included" in the spindle box
  • Fewer components and easy installation
  • Economical standard solution as compared with today''s belt-driven solutions
  • Drive train with high degree of rigidity
  • High torque and speed and therefore high productivity thanks to high cutting efficiency and reduction of non-productive time
  • Higher speed and shorter start-up times as compared with conventional belt-driven or gear solutions
  • Economical pneumatic tool release mechanism or optional fast hydraulic tool release mechanism
  • Worldwide system delivery including spindle mechanics from a single source – from Siemens
  • Extremely short tool change times with 2SP210 thanks to 2-channel technology and clamping set with optional latching capability
