Description / Abstract:


The first edition of this standard, known as BS.18-1943, resulted from intensive efforts dating back to 1926 by a special group of milling machine manufactures; it was reaffirmed in 1949, revised in 1953 and again in 1960. ASA Spindle nose size designated as 50 A, suggested by the ‘Society of Manufacturing Engineers' and several recommendations made by national Tool Builder's Association. The revised standard reflected accurately the actual practice at this period of time.
