OUR readers will be fully acquainted with the range of porous oilfilled bearing materials, impregnated bearing materials, and similar sintered materials by other names, available from several manufacturers and all filling very useful purposes for onethousandandone machine parts. Any new bearing material is of interest to designers, especially those with tribology in mind.

These authors reported work on cutting oils in our SeptemberOctober 1972 issue and this paper describes a continuation of their work. The selection of special cutting fluids and lubricants can significantly affect metal cutting operations. Friction forces during metal cutting can increase the amount of work to be done to deform the material, can increase tool wear, and can increase surface roughness of the workpiece. The frictional force can be reduced by the correct selection of cutting oil. In this paper the authors describe work to investigate the performance of molybdenum disulphide and graphitebased cutting fluids and lubricants when machining mild steel under different processes. The results suggest that graphitebased fluids give the better results under these experimental conditions.

THERE is some doubt in haulage contractors' minds that the compulsory fitting of tachographs to commercial vehicles, to ensure that legal travelling distances are observed, will make some existing gearboxmounted automatic lubricating systems impossible to install, because the speedometer takeoff point to which they are connected will in future activate the sealed on tachograph.
