SIEMENS RETROFIT OF CNC ROLL GRINDER

The project comprised a full Siemens Retrofit of a Herkules P100 CNC Roll Grinder.

Mechanically, the machine was in quite good condition, therefore, the only remedial mechanical work was to refurbish the Axis Drive Ballscrews and laser re-align the Machine Beds & Wheel Slide.

Electrically, the machine has been retrofitted with a new Siemens 840D Control, new Siemens DC Spindle Drives to both the Wheel Head & Work Head, new Digital Axis Servo Motors & Drives (X, Z and C), a new Electrical Cabinet, complete with all new control gear, and a complete machine re-wire.

MACHINE SPECIFICATION

  • Herkules P100 WSB 450 Roll Grinder
  • Max. Roll Length = 12,500mm
  • Max. Roll Diameter = 1,500mm
  • Crowning
  • Diamond Wheel Dresser
  • Roll Cal Gauging System

COMMENTS

This machine is key to our Clients entire production process; it is the largest Roll Grinder they have and the only machine with ‘Crowning’ capability. Unreliability of the old CNC & electrics regularly caused severe bottlenecks in their manufacturing programme.

Not only has the CNC Retrofit significantly improved machine availability, but the re-alignment of the machine has also vastly improved machine accuracy.
