Abstract

602,574. Boring and drilling. ROSSMANITH, W. Dec. 12, 1945, No. 33658. [Class 83 (iii)] Boring-heads.-An accurately countersunk hole is finished by a rotating cutting-tool which is moved on a path inclined to its axis of rotation at an angle corresponding to the required angle of countersink. A headstock 4 carries a drillspindle 5 and a toolspindle 13 rotated by a pulley-belt 10. The hole is first drilled by the bit 8 ; the headstock is then moved to feed the tool 1 into the hole to form a countersink and the countersink is then accurately finished by withdrawing the tool 1 on its slide 9, which is inclined at the correct countersink angle α by means of a wheel 17, the spindle 13 and a link 14.
