NCTP-300 Non-Contact Internal Flaw Detection Instrument

The NCTP-300 non-contact thread inspection instrument

The NCTP-300 is a non-contact thread inspection instrument controlled using an industrial, touch screen computer developed to “error proof” automatic machining processes such as threading.

Spring-loaded, inductive probes sense internal threads by the amount of metal removed or displaced in the tapping / rolling operation. Variations in shape and amount of metal in the electromagnetic field are detected and displayed on a 3-D image with hole locations and identification.

NCTP-300

A plus and minus Accept/reject tolerance is automatically set by comparing known good part voltages with known defective part voltages. Missing, shallow and/or damaged threads are detected as they fall outside the accept/reject tolerance.

Communication is available through Remote I/O, Local I/O, RS232 for machine control are standard.

 
 
 

Probes are designed specifically to work in harsh manufacturing environments. Unlike other thread detection instruments, which require clean and dry parts, the NCTP-300’s accuracy is not affected by coolant or oil. Threading processes are 100% verified in-line assuring defects are detected as soon as they occur.

The inductive probes are spring loaded to avoid damage from broken taps or holes not properly located. The probes spring back when contact is made causing the voltage reading to remain outside the accept tolerance causing a part rejection.
