These centres are safe, secure and offer greater versatility and accuracy than the usual two or four prong drive centres. The centre features a spring loaded, stainless steel centre point and a sharp toothed outer ring which provides the drive. The Axminster Evolution Series Pro Drive is unique in that you can vary the spring tension. There are numerous advantages when using this drive. Repositioning your work is accurate; the work always goes back in the same place. They are safe; reduce the pressure from the tailstock and in the event of a dig-in the work will simply stop revolving. Reducing the tailstock pressure further allows you to stop the work and inspect it without switching off the lathe. In production, the centre allows unloading and reloading by unwinding the tailstock without stopping the lathe. When used for eccentric turning, the centre will still drive even if its full diameter is not in contact with the work.
