Discussion on "Standardisation in relation to production engineering" at the Yorkshire Section of the Institution

MR. J. GRATRIX, who presided, said that Mr. le Maistre had purposely left them plenty of time for the discussion of his paper. There were many important points to be considered and one that would interest production engineers was whether the British Standards Institution had done anything with regard to the standardisation of machine tools. He pointed out that it was a source of worry to the designer who had to design a firm´s equipment to find the particular machine tools he needed all varying. What standard had been determined upon for spindle-noses ? In relation to tolerances there was the question of bi-lateral or unilateral systems.
