RASOMA Werkzeugmaschinen GmbH, Germany

RASOMA from Germany, formerly Liebert & Gürtler, was founded in 1919. Their newest products in development are the CNC-controlled machining centres where they endwork shaft-type components.

In addition to these developments, customized solutions for the interlinking of machining centres, workpiece handling and storage systems as well as special purpose machines for specific machining tasks are designed and manufactured.

Products from RASOMA

Products manufactured in series

Vertical Lathes

DS Series - Features

  • Very high stiffness
  • High thermal stability
  • Short non-productive times
  • High flexibility

DZS series - Features

  • Newly developed DZS comes in 4 sizes, single-spindle, twin-spindle
  • Can also be equipped with extra machining unit for high-performance milling, engraving and other procedures.
  • Our centres can also be operated with two independent cross slides so that two processes can be performed simultaneously.
  • The longitudinal slide glides along three linear guides and has a linear drive. This results in extremely high stability with a simultaneously high dynamic (speed 120 m/min, acceleration 5 m/s²).

End Machining Centres

Horizontal end machining centres EBZ

  • EBZ 60/250: Work lengths up to approx. 500 mm.
  • EBZ 250: Vertical lathes series- DS and DZS approx. 500 - 2,500 mm

Machining Centres for rotationally symmetric parts

RBZ 2 The machining centre RBZ 2 is a heavy-duty machine equipped with components of renowned manufacturers for demanding machining tasks with high requirements to dimensional stability, geometrical accuracy and surface finish. Thanks to a high division of cuts an extremely short machining time is obtained. The times for feeding and take-off of the workpiece are not included in the essential operating time.

Configuration of the machine depends on the piece to be manufactured. The machining units are arranged in the necessary position on the machine column. The machining units comprise the spindle drive for the tool, the eccentric drive for the radial facing slide (x-axis) and the feed axis (z-axis), driven by digital servo drives. It is possible to arrange up to eight machining units at the same time. Loading can be dimensioned according to the workpiece, e.g. with timing disc for separating and measuring.

EBZ 400 CNG - Bottom end and neck machining of gas cylinders

This machine has been designed for the complete machining CNG gas cylinder necks in less than one minute. Depending on position and specification, the machine can be used for the machining of cylinder necks with various millings and threads.

Special Purpose machines

Double-spindle special purpose machine DSP 360 - 2 for perforating braking discs

The double-spindle special purpose machine has been designed for the perforation of braking discs. Any number of holes can be drilled with that machine. The unmachined parts are fed by an automatic loading device which is coupled to a workpiece alignment in order to place the various boreholes in the right position on the braking disc. In addition, a height-positioning system ensures that the braking discs are adjusted to the different heights. The measured values for height adjustment during machining are deposited in the control unit. For each type of braking disc, a machining program for the respective drilling pattern is stored in the control unit. A reversing station connects first and second clamping. A storage unit is used to feed out the finished parts.


Special drilling machine for the accurate axial machining of shift sleeves

This drilling machine is used for the efficient and accurate axial drilling of fits to shift sleeves. The work pieces are fed by means of clamping units on the rotary transfer table which supply the work pieces with clock pulses into the working space. The drilling tools are situated on the left-hand and right-hand side of the work piece in both motor spindles. ( Eccentric machining possible). There is a crown-type turret placed in the centre behind the work piece in a 90° angle to the drilling spindles that provides the possibility to cam in up to 6 tool units.
