II. START UP AND OPERATION
1. Cutters and optional equipment features
This dril
ling machine’s spindle has a socket with Morse taper which make possible to use
twists drill (if it necessary with using drill sleeves) or milling cutters by using AMT Arbor for
fixing them in socket spindle taper [Drawing 2].
Milling cutter (2) is located inside arbor body (1) and is fastened with screws (3). While
fastening the cutter in the socket, be aware that screws should be screwed tight so that they
could not come unscrewed. It is important to position the cutter in relation to the socket in
such a way that fixing flats on the cutter shank are positioned opposite to the fixing screws
(3). Both fastening screws (3) should be used to fasten the cutter. Pilot (5) is located inside
the cutter. It makes it easier to position milling cutter over centre of a planned hole. During
drilling as the cutter goes deep into steel, the pilot moves back into the arbor body and
tightens discharge spring (4). That spring ejects slug which is a by-product of milling a hole
with a centre free cutter.
Basically milling cutters are designed to make through holes. On occasions when there is a
need for an overlapping hole pilot should not be used. [Drawing 3]
