The difference between these machines and conventional solutions lies in their advanced design. The RWT team has acquired this in practice through many years of experience in the field of thread and profile rolling.

In order to meet the increasing demands of technology and user-friendliness, we have developed an innovative control concept for our machines in cooperation with the Beckhoff company.

CNC Gewindewalzmaschinen

CNC thread rolling machines from RWT are distinguished in multiple ways through:

  • Powerful industrial PC with Intel processor
  • Touchscreen panel with additional hardware keys and full keyboard
  • Control software based on Beckhoff TwinCAT with integrated Soft PLC
  • Full graphical user interface
  • Digital drive technology
  • EtherCAT interface
  • Simple program input in tabular form
  • PLC functionalities can be integrated directly into the CNC program sequence
  • Automatic plausibility check of the programs
  • Editing of programs also possible externally
  • Integrated monitoring strategy (for example, rolling force monitoring)
  • Remote diagnosis and maintenance possible via the Internet

Furthermore, the machines naturally offer the proven advantages of the previous generations for thread rolling:

  • Available from 200 – 600 kN
  • Rolling force roll stand with tie rod construction for maximum rigidity of the roll stand
  • Lagerung der Walzspindel mit vollrolligen, käfiglosen Zylinderrollenlager für maximale Tragkraft auf kleinstem Raum
  • Roller slide guides with maintenance-free, low-wear plain bearings. This eliminates the need for central lubrication
  • Stable welded frame as a substructure offers flexible expansion and attachment options
  • Hydraulics, coolant units integrated in the machine as modular, service-friendly individual assemblies
  • Elektroschrank fahrbar neben der Maschine angeordnet
  • CNC control: for 1 to 10 axes
  • A wide range of accessories, extensions and automation concepts

Precision

  • ± 1 µm for linear axes
  • ± 0.001° for rotatory axes
  • ± 0.002° for swivel axes

Drive

  • Robust three-phase drive in conjunction with standard worm gears with 1-axis control
  • Three-phase servo drive in conjunction with standard worm gears from 3-axis control
