Cazeneuve "Universal" hydraulic copying (tracer) attachment that mounted on the HB500, HB575 and HB725. The unit was able to perform both longitudinal and traverse copying and was available with a variety of toolposts including a special high-accuracy 4-way type. A mechanism was incorporated that allowed a finish cut to be taken immediately after roughing was finished without having to remove or adjust any component. Each unit was scaled for the particular lathe with slide travels of 96, 96 and 134 mm for the HB500, HB575 and HB725 respectively together with a common slide speed of 3 metres per minute
