2SP1 motor spindles for SINAMICS S120

Заказные данные
(12)

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

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 motor spindles are available in 2 diameters of 200 mm (7.87 in) (2SP120) and 250 mm (9.84 in) (2SP125) and are offered with a range of different torques and speeds 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.

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.

Дизайн

A key feature of 2SP1 motor spindles is their rugged design.

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

Various tool interfaces
Internal tool cooling
External tool cooling

2SP1 motor spindles in asynchronous design with star-delta changeover

2SP1 motor spindles in synchronous design

Интеграция

The 2SP1 motor spindle are generally compatible with:

SINAMICS S120
SINUMERIK 840D sl

For the synchronous version of 2SP1 motor spindles, a VPM Voltage Protection Module or the Internal Voltage Protection IVP must be used as an integrated SINAMICS function, see Voltage Protection Module VPM.

Особенности

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

Compact spindle solution and everything integrated 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
