Material
4.2.1 Round bars
To guarantee a perfect insertion of the bars inside the
collet of the bar feed system, it is recommended to
chamfer them in the rear at 30o.
Likewise, to avoid possible catching during the
introduction in the spindle, the bars must be well
deburred at the front.
In some cases, when the diameter of the bar is close to
the external diameter of the collet (see Chapter 7, point
3.3 - Assembly of the pushers), the rear of the bars must
be machined to the inside diameter (D) of the collet.
The length of the machining (L) must be at least 30 mm
4.2.2 Tubes
When loading tubes, in order to avoid mixing the bar
feed system oil and the cutting oil, it is recommended to
make plugs. These plugs must be installed at the rear of
every tube.
4.2.3 Shaped bars (hex and square)
It is recommended to install a bushing, inside the clamping device, with the same inside
profile (+ 0.2 mm) as the bar.
The rear of this collet and the front of the bars should be flat.
During the loading cycle, a slight rotation of the spindle (about 30 RPM) is desirable.
