Using the Drawbar
The drawbar has a M12 x 1.75 right-hand thread and should be
tightened with normal pressure using a wrench. To loosen the collet,
back off the drawbar, and if the collet does not open, give the top of
the drawbar a slight tap. The spindle has a non-sticking taper and the
collet should release readily. When tightening or loosening the
drawbar, it is necessary to lock the spindle. To do this, use the spindle
brake which is located on the left side of the belt housing, turning it
either left or right until it binds. Make sure the quill feed handle is
raised all the way.
The drawbar is especially useful during tapping to prevent the tapping
chuck from becoming loose when the spindle changes direction.
Removing Tooling from the Spindle
1. Disconnect machine from the power source.
2. Place a piece of wood on the table for protection.
3. Position the work table approximately 10” under the bit and
lower the spindle about 6”.
4. Place the drift key (customer supplied) (AI) into the slot (AJ) of
the quill and tap the end of the drift key with a hammer until
the bit or chuck arbor falls out.
Chips During Machining
The machining process removes material from the piece. This material is released in chips,
which can be of different shapes depending on the material itself. The most common ones are
of three types: fragmented chips in small bits, short helicoidal chips and long helicoidal chips.
The chips fragmented in small bits can be rejected from the machining area and can be
dangerous if they reach the eyes of the operator. To avoid this, it is advisable to wear safety
glasses.
The long helicoidal chips tend to roll up the tool and gain considerable volume before breaking,
which is dangerous if they reach the operator as they may produce injuries.
The reached volume may also displace the dill protector from its security position, increasing the
risk of an accident. It is advisable to use chip breaking tools to machine materials which produce
such chips. For further information contact the tool manufacturer.
