306 / Super Abrasives SUPER ABRASIVES Dressing of profiles with blade tools Dressing tools use a ‘needle’ form of natural or synthetic diamonds. Needle diamonds are especially suited to dressing profiles using infeeds and angular feeds. Natural diamonds An effective diamond layer with a length of up to 15mm creates an economical dressing solution. Using precise diamond setting patterns, with overlapped rows of stones, ensures that consistent dressing results are achieved. Synthetic diamonds The constant cross section given by synthetic diamonds, guarantees a constant dressing behaviour through the complete life of the dressing tool.

The lifetime of the dressing tool is extended by ensuring that adequate coolant pressure and volume are directed at the tool.
