Emuge Punch Tap line

Emuge Corp. introduced its patented Punch Tap Line in North America.

Emuge Punch TapThe Emuge Punch Tap is the first tool/ technology of its kind for helical thread forming in cast and wrought aluminum alloys and similar lightweight materials. Emuge Punch Taps provide a new, shortened tool path process for producing internal threads in under half a second, resulting in significantly less energy consumption during the machining process and a reduction in threading time by 75% compared to cold forming and conventional tapping.

"Emuge originally partnered with Audi AG in Europe to develop the unique Punch Tap design and technology," said Bob Hellinger, president of Emuge Corp. "This revolutionary tool is exceptionally productive and we are thrilled to now offer the technology to our customers in North America." Due to its extremely fast threading capabilities, high volume applications such as in the automotive industry are ideal for the Punch Tap. Emuge Punch Taps provide an excellent thread production solution for manufacturers who produce high volume parts and need to reduce cycle times.

Punch Taps are made from a special HSSE-PM alloy optimized for toughness and long wear, and have an exclusive design offering several benefits such as unique teeth geometry that produces threads in a single step. The Punch Tap features two rows of flutes off-set 180° from each other and extending in a helical curve all the way down to the usable application depth. This design enables an extremely efficient tool path that is approximately 15 times shorter for a M6 thread with a depth of 15mm compared to traditional cutting or cold-forming taps. The shortened tool path facilitates a threading process which is completed in less than half a second.
