Original Press Release:



Thread Verification Unit (TVU) Developed by New Vista Corporation



Baltimore, MD- New Vista Corporation has developed an automated Thread Verification Unit (TVU) that performs inspection of internal threaded holes. A more certain alternative to eddy current sensing for high volume manufacturers, the TVU quickly and automatically checks threaded holes by powering a probe into and out of the part. The all-electric unit employs a sensitive high-speed drive that allows the probe to stop in case of missing or malformed threads, registering a fault.

The TVU comes in two basic models: servo and nonservo. A servo TVU, which includes a servomotor, servodrive, and motion programming, can check a thread as quickly as a second, where the thread length is equal to the diameter. A nonservo TVU, which includes a mounted brushless DC motor with speed control, is a lower cost alternative with cycle times starting at 3 seconds. Both servo and nonservo TVUs will verify thread sizes from 3mm to 25mm (#4 to 1"). Larger sizes are quoted as specials.
