7. To Polish an Edge
Your machine will be supplied set up with a cutter hub and ready to polish. To polish
an edge proceed as follows:
Select your piece of material
The 1550 will accept pieces of material of thicknesses up to 55mm. Should you wish
to polish thinner materials, these can be polished as packs up the 55mm maximum.
The minimum panel size which should be polished is 100mm square. The ends of
longer rods or bars of material can also be polished, but care should be exercised.
The 1550 will polish most thermoplastic materials. It must be noted however that
cutter life will vary depending upon the characteristics of the material being polished.
Cutter life can be improved by adjusting the transport and spindle speed to suit the
material. These adjustments should be made as follows:
Spindle
Harder materials – e.g. Cast Acrylic
50Hz (Max Speed)
Softer materials - e.g. PETg, Polycarbonate
30Hz (Min Speed)
Transport
Harder materials - e.g. Cast Acrylic
Speed 2-3
Maximum speed that does not
chip the edge
Softer materials -
e.g. PETg, Polycarbonate
Maximum speed
Switch on the machine as described in Section 7 above. Set the spindle and
transport speeds and start the motors.
Load the material vertically onto the infeed (left hand) track.
Push the material until the transport system grips it and starts to feed it into the
machine.
At this stage, let go of the material, and let the machine transport it over the cutter
and polish the edge.
Once the material has been released from the transport, remove and inspect.
Note that the piece being polished must have exited the transport system before the
next piece is loaded. Failure to observe this could result in damage to the cutters.
After use, switch off the machine.
