5. START UP AND OPERATION
5.1 Cutters and optional equipment features.
This drilling machine’s spindle has a Weldon Shank type socket 3/4” or
19,05 mm and is specifically designed for use with milling cutters.
Milling cutter (1) is located inside arbor body (2) 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.
