When the lid is removed, the
adjustable rotating probe is visible "keyholes"
provide for easy disassembly. |
For maintenance and
resetting, the rotating head is brought into
maintenance position. |
 |
 |
|
The 2-channel rotating probe
can be adjusted finely from 1.0mm to 15.0mm. |
The integrated drawers offer
sufficient space
for master parts, tools and exchange parts. |
|
 |
 |
|
Parts are fed in a flexible
tube from the vibration feeder. They are
transported through the rotating head via feed
wheel at a constant velocity (v s 100mm/sec).
After testing is completed, the parts go one by
one to the ok parts box or the REJECTED parts
box, depending on the sorting decision. |
The control elements and the
electrical components are integrated in the
dust-proof steel cabinet. the frequency drive
allows for the high speed of the rotating head
(600 rpm). |

The parts are separated
gently at the test parts inlet and passed one by
one to the test and discharge stations. |

The I.D. crack detection
probe in its protected home position awaits the
next test part. |
At the upper chute, OK parts
are forwarded to the next processing step. The
lower chute can hold up to five NOK parts. |

machinery.
The system is designed for three
different part types with part ranges: |
 |
|
|

200 to 350mm |
| |
Diameter: |
Approximately
120 to 130 mm |
| |

Crack and pore detection on the inner
diameter and flange end faces.
Test for correct case depth at up to 16
locations. |

Structure Test Station
An I.D. coil tests pre-selected
locations on the inner diameter for
correct case depth.
|
Crack
Test Station
The cylinder liner is rotated and the
I.D. bore surface area plus the flange
face are scanned for surface open cracks
and pores. |
| |
|
After the part is
marked, it is forwarded to the sorting
station where it is sorted either into
the OK or NOK chute. |
 |
| |
|

The robust swivel arm transports the
part from station to station. |
