Abstract

1,226,506. Centres; centre drilling. M. MATSUMOTO. 12 Feb., 1969, No. 7487/69. Headings B3B and B3C. A lathe centre 7 having a rotary mounting centre shaft 8 is adapted to drill a centre hole by mounting thereon a drill-holding member 9 which includes a tapered socket 13 for holding a collet 14 which grips a centre drill 15. The member 9 is engaged with the centre 7 by means of a pin 11 and hole 12 to prevent relative rotation. Alternatively the member 9 may be connected to the centre 7 by radial pins (20), (Fig. 3, not shown), engaging oblique grooves (18).
