Winterthur Grinding Handbook For Employers
• 257 Downloads Abstract This paper presents the results of comparative experimental tests of proper active powers and maximum temperatures, conducted on the circumference grinding of flat surfaces, made of grade 321 corrosion-resistant steel (1.4541), using modern aluminium oxynitride and noble electrocorundum vitrified-bonded grinding wheels. The tests were carried out in both up-cut and down-cut conditions. In both kinematic grinding aspects, the tested factors were determined by discrete increase of reductive grinding yield, applying increasing grinding-wheel in-feed to the workpiece and keeping the remaining grinding parameters at the constant level. The test results were later subjected to simplified statistical analysis, and an attempt was made at substantive test justification. It was demonstrated that, regardless of the assumed kinematic grinding aspects of steel grade 1.4541 (321), the values of all the comparatively tested values of aluminium oxynitride grinding wheels were, with increasing reductive grinding yield, lower than the corresponding values of the noble electrocorundum grinding wheels.
Innovative bonded abrasives for grinding ultra-hard steel are the result of close cooperation between the experts of the diversified technology company 3M and the specialists of Winterthur Technology, a 3M subsidiary. The predominant feature of the new Cubitron II ceramic grains developed by 3M for this abrasive is their precisely-shaped, uniform-sized which results in even.
