Centerless Grinder Rebuild

The Centerless Grinder Rebuild comprised a full machine refurbishment & CNC retrofit of this Cincinnati 2 0M Centerless Grinder.

The machine refurbishment included strip to component level, re-machining & scraping of all Slideways (Infeed & Dresser Slides), re-engineer Infeed Drive to provide Ballscrew & Servo Control, re-engineer Grinding Wheel Dresser to provide 2 axis Servo Control; refurbish Regulation Wheel Dresser, fully refurbish Spindles (Grinding & Regulation Wheel) including Hydrodynamic Bearing arrangement, complete new hydraulic system, complete new coolant system and new extraction system. In addition, a complete new Guarding Enclosure has been designed & fitted to provide PUWER compliance.

The CNC upgrade comprised fitting of a new Siemens S7 PLC, new Siemens AC Spindle Motor & Inverter Drive (Grinding Spindle), new Siemens Servo Motor Drive to the Regulation Spindle, new Siemens Digital Axis Servo Motors & Drives and a complete new Electrical Interface.
