Waldrich Siegen Plano Milling Retrofitting with SINUMERIK 840C/SIMODRIVE 611A for Texmaco - Indonesia

Waldrich Siegen Plano Milling machine has been retrofitted with SINUMERIK 840C for PT Texmaco Perkasa Engineering, Indonesia. This machine has been manufactured in 1977. While still having excellent mechanical parts condition, the existing control and electrical equipment need to be replaced to achieve better reliability and accuracy.

The machine has been succesfully retrofitted and back into production in 1998. Siemens SINUMERIK 840C CNC control is a nature choice to accomodate 4 analog axis control requirement

• X Traversal Table
• Y Milling Head Cross
• Z Ram
• W Spindle Longitudinal
• Spindle 74kW

CNC Design have supplied new axis motors from1FT5 series in conjunction with world wide proven servodrive from Siemens: SIMODRIVE 611A.

The existing 74kW 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.
