Numerous versions of this type of machine have been designed and produced over the past 50 years. They are designed for specific applications and vary from manual operation to fully automatic. The machine shown here is an example of an automatic single end needle bearing machine.
The auto sequencing is:
1. Loader pushes the part into the nest
2. Next is moved in front of insert unit
3. Insert unit loads needles into the gear housing
4. Nest with the finished part returns to load/unload position
5. Loader pushes the new pinion in and finished part out
This entire process only takes on 3 seconds to complete. At this rate, operating at 100% efficiency, the machine can produce 1200 parts per hour.
