RDM 4 – no Pallet



no Pallet version


Table rotation speed: 3.000 giri/min
Rapid speed X and Z axes: 36.000 mm/min


monolithic steel, electro-welded
stabilised and normalised.

Machine weight: 22.000 Kg


Spindle motor power: 92 kW
Spindle torque: 670 Nm


Composed of an independent, interchangeable cartridge with an integral, high-power, liquid-cooled asynchronous motor (92 kW). Very fast acceleration and braking times (3 seconds).


Large machining area, meaning it can machine rims of up to 24 inches in diameter and 15 inches high.



astek know the needs of the automotive market. Saving just one second in the production of a single part increases productivity over millions of pieces.The vertical lathes from the RDM range have been designed for companies manufacturing light alloy rims. These machines offer the highest levels of performance, are fully customisable and are ready to be used to their full potential. They adapt well to increasingly more demanding and higher performing production cycles.This is the reason why we invest commitment and resources to constantly perfecting our engineering and finding solutions that:

  • increase production capacity and flexibility
  • reduce costs and save time
  • improve quality and reliability
