The DSG (Dean Smith and Grace) 1508 Pioneer lathe had electrical issues due to the age of the CNC, Drives and electrical equipment. Replacement of the CNC and electrical systems using previously proven Seymour projects produced a functional and reliable machine the we use in our own machine shop.
Some of the issues that have been found and addressed;
- The Philips 3000 CNC was no longer reliable
- The GEC Spindle drive was not responding correctly
- There were wiring faults and intermittent failures
- The Tailstock required stripping down and servicing
- Measuring system issues
The machine was completely overhauled and retrofitted to bring it back to good working order. The final result was a machine that was more capable and much easier to use than the original new spec.
A Fagor 8055TC was chosen as it was a very cost effective system and allowed the existing Analogue drive setup to be used whilst bringing state of the art features and graphical, conversational programming features to the machine. It also had the special features required to ensure that critical timing requirements for the Sauter turret could be guaranteed.
The project included;
- New Fagor 8055 TC conversations CNC Control
- New Spindle Servo drive
- New Safety system including Emergency Stop
- New Guard interlocking
- Re-Wire
- Overhaul of the Sauter turrent
- Overhaul of the Lubrication System
- Overhaul of Ballscrew and replacement bearings
- Stripping out many of the Electrical components
- Many New Electrical parts
- Much simplified Electrical Panel
- CNC and PLC control of many of the original Hard wired relay based electrics
- Full alignments and geometries
The machine utilizes the Seymour E-SHOP, E-Turn philosophy. Previous work assisting Dean Smith and Grace develop their retrofit program was brought to bear especially with the Sauter turrent operation requirements which not all controls could reliably control. The work previously carried out with Siemens 840D controls translated onto this project and many of the potential problems seen by other implementations of DSG lathe retrofit were avoided.
The Efficiency drive of the E-Shop philosophy is obvious in the Electrical design. New components, intelligent system design and software based instead of relay based logic meant many fewer components are required and much more free space is in the electrical panel than the original design.
