New Double Tapping Facility available at Hamond Industries
Hamond has, for years, had the ability to put one accurate tapped hole into a formed part manufactured on their slide forming machines. While this slighly increases the cost of the formed part, the incremental cost is vastly lower then the cost of an operator on a separate tapping machine. In addition, the quality of the resulting threads (locational accuracy, perpendicularity, thread completeness, thread hardness) are all vastly superior to separate operator-actuated tapping machine.
Hamond has in the last year acquired the facilities to double tap parts. That is, a part needing two identical threaded or tapped holes can be automatically tapped as easily as parts needing only one threaded hole. The incremental cost is low - the incremental cost of the second hole is generally less than half the incremental cost of the first one, which is itself quite low.
In addition, responding to customer requirements, Hamond has developed 2 additional abilities:
1. to tap after forming
2. to tap through 2 material layers
The ability to tap after forming allows us to tap very close to a material fold or other stretch feature without endangering the thread quality or circularity. This capability, which is only available for certain shapes and by pre-arrangement at design time, allows us to eject the part from the main forming area of the machine while retaining accurate part registration. This allows us to tap the part after forming but still on the machine, still synchronous, still in accurate registration, and therefore allows us to make the same high quality tapped hole as when we tap the strip before forming.
The ability to tap through 2 material layers allows us to make one thread that is continuous through two material layers. This allows the part designer the freedom to double material in some areas for extra strength, and still have a tapped hole feature in that area.
For our "tour de force", there is one job where we combine all three facilities - double tapping, tapping after forming, and tapping through doubled material.
We would be happy to quote on your drawings of parts needing these facilities and, if necessary, suggest engineering changes to make the part amenable to these new process capabilities. Our Sales Manager, John Sheehy, will be happy to assist you. You can reach him at our main phone number (905) 761-9094 or by email as john.sheehy@hamond.com
