Dorries-Scharmann Heavy Cutting Milling Machine Retrofitting with SINUMERIK 840C/SIMODRIVE 611A for Texmaco - Indonesia

Dorries-Scharmann Heavy Cutting Milling machine has been retrofitted with SINUMERIK 840C for PT Texmaco Perkasa Engineering, Indonesia. This machine has been manufactured in 1980. While still having excellent mechanical parts condition, the existing control and electrical equipment need to be replaced to achieve better reliability and accuracy.

CNC Design have supplied new axis motors from 1FT5 series in conjunction with world wide proven servodrive from Siemens:SIMODRIVE 611A.

The existing 75kW DC motor for spindle has been reused as it was still in good condition. Reusing the existing large DC motor for spindle cut retrofitting cost. Siemens Simoreg DC drives was used to drive the existing DC motor.

The machine has been succesfully retrofitted and back into production in 1998. Siemens SINUMERIK 840C CNC control is a nature choice to accomodate 6 axis control requirement :

  • X Coloum Traverse
  • Y Head Stock Vertical
  • Z Support Beam
  • W Spindle Longitudinal
  • V Table Longitudinal
  • B Rotary Tabl
