What the center is intended for:
Automatic cutting of profiles, featuring all types of cross sections and shapes, to length and with any type of angle; after this, the profiles are deburred (with brush deburring) and are then placed on a finished part buffer space. |

Sequence description:
- The profiles are manually placed on the buffer bin (shuttle) by the operator
and are then slid axially until they hit a stop (infeed track).
- The profiles are separated automatically and are then transferred onto the
roller track.
- The NC feeding gripper positions the profile in the HM compound miter saw.
- The corresponding length and/or angle is cut according to the program.
- The NC section gripper takes the cut profile and moves it to the transfer
position for the transport shuttle.
- The profiles are moved transversely from the transport shuttle to the next
stations (NC brushing station and air cleaning station) in cycles.
- The various cut angles are deburred with rotating steel brushes in the NC
brushing station.
- Swarf is blown off from the profiles as much as possible in the air cleaning
station.
- The finished parts are placed on the buffer belt and the profile lengths are
measured.
- The profiles are output for manual removal.
