Commonly used by the factories which need large production rates, in particular those relevant to the automotive industry, the CNC multiple-spindle lathe allows simultaneous machining operations.
As the name suggests, the CNC multiple-spindle lathe is characterized by the fact that it has a several spindles 6 and 8, and by the presence of a digital control.
With the CNC multiple-spindle lathe, different bars independently feed its many spindles and the workpieces go by a different tool at each cycle.
The machining of a workpiece is boken down into all of the spindles and the manufacturing of a workpiece is determined by the time of the longest operation.
The multiple-spindle lathe is an automatic lathe. The machining of workpieces is hence done according to a predefined setting.
This type of automated systems, allows, among others, to reduce tools change times to their minimum threshold and to perform machining in large series. It facilitates the machining of complex workpieces from bars or billets.
The CNC multiple-spindle lathes can have a big number of axes; in fact, there are models with 14, 17 or even 32 axes.
The performance, productivity, and speed of CNC multiple-spindle lathes are accentuated by the integration of the digital control. The hydraulic, electronic, and electromagnetic servo-control mechanisms are managed by the CNC.
The software component along with the mechanics of the multiple-spindle lathe makes its maintenance requiring a great deal of expertise in the area.
The RDMO workshops possess this kind of skill, which allows making extensive checking on second-hand CNC multiple-spindle lathes present in their catalog. By examining the different models available in every tiny detail, they make sure that they have a quality level as close as possible to that provided by new equipment.
Today, the major stakeholders in the manufacturing market of CNC multiple-spindle lathes are Gildemeister, Index, Tornos, and SCHÜTTE.
According to official recommendations, we are setting up teleworking for the majority of our collaborators from Tuesday 17.03.2020 12pm and until further notice.
