Description & Features:The Our Backplates are made of special cast iron and are very sturdy in design. The tapers on the Backplates are manufactures to a close tolerance, giving a very close fit to the spindle, thus ensuring a high degree of accuracy.
Selection of Backplates :The Backplates should be chosen to suit the spindle of the machine. The common spindles are A type, D Type, L Type and threaded spindles.
Having dtermined the type of spindle, then the size of the Backplate should be selected. For instance, in the A Type of spindle there can be A4,A5,A6 and so on.
The diameter of the Backplate should be chosen so that it is more than the diameter of the chuck . The extra diameter should then be machined, on the same machine on which the chuck is to be mounted. After maintaing a close fit, the chuck should be mounted on this diameter.
