Abstract

993,260. Drilling. G. & D. DONALDSON Ltd. March 8, 1963 [March 9, 1962], No. 9155/62. Heading B3C. A drilling machine comprises switch means operable by relative movement of the spindle and its quill. The drill is rotated through a telescopic universally-jointed shaft 15 and is fed by hydraulic means 20. When the drill contacts the work it is moved axially against a spring 16 and a rod 17 operates a switch 30. Operation of the switch causes the feed rate to be reduced. Contacts 31 associated with the switch engage elongated strips 32 to allow lateral adjustment of the drill. In a multiplespindle machine each drill has a switch, operation of one of the switches causing a reduction in feed speed of all the drills.
