ʻĀpana Spiral Groove
ʻOi aku ka maikaʻi o ka wehe ʻana i nā puʻupuʻu i ʻoi aku ka lōʻihi a kūpono hoʻi no nā lua i hoʻohālikelike ʻia me nā awāwa pololei. ʻO ka hemahema ʻo ia ka lōʻihi o ka uwea kūpono ʻole ma ka piko.

ʻO ka pilina hoʻohālikelike maʻalahi ma waena o ka ʻohe pololei, ka ʻōheʻe spiral a me nā paipu ʻōheʻe spiral:

Piʻi ʻopeʻa wili
Hoʻohana nui ʻia nā ʻauwaʻa spiral no ka wili ʻana i nā puka makapō. I ka hana ʻana i nā mea hana me ka paʻakikī kiʻekiʻe a me ka ikaika, hiki ke hoʻohana ʻia nā paʻi me ke kihi helix liʻiliʻi no ka hoʻomaikaʻi ʻana i ka ikaika hana.

No ka mīkini ʻenehana 400 series stainless steel (15° helix angle)

No ka hana ʻana i ka 300 series stainless steel (helix angle he 41°) Fig. 3 Spiral flute tap

Spiral vs. Apex Spiral
He kūpono ke ʻano spiral no nā puka makapō, a hoʻokuʻu ʻia nā mea hao i waho o ka lua. Helical ka piko, a wehe ʻia nā ʻāpana i lalo.3d mīkini

Hoʻohālikelike intuitive o nā ʻano pololei a helical

Paʻi ʻana i nā mea hana mea hana kūikawā
ʻO ka machinability o ka mea hana mea ke kī i ka paʻakikī o ka paʻi ʻana. Wahi a nā waiwai o ka mea, he mea nui e hoʻololi i ka geometry o ka ʻāpana ʻoki o ka pā, ʻoi aku ka nui o kona kihi rake a me ke degere o ka concave i mua o ka nui concave.4 axis cnc machining

ʻO ke kihi rake a me ka sag
ʻO ka mīkini ʻana i nā mea hana ikaika kiʻekiʻe
No nā mea hana mea hana kiʻekiʻe, ʻoi aku ka liʻiliʻi o ke kihi rake a me ka ʻoki ʻia ʻana o nā paipa, e hoʻonui ana i ka ikaika oki. Pono nā mea ʻoki lōʻihi i nā kihi rake a me nā ʻoki lalo no ka wili puʻupuʻu a me ka haki ʻana. ʻO ka hana ʻana i nā mea hana ʻoi aku ka paʻakikī e pono ai nā kihi hoʻomaha nui aʻe e hōʻemi i ka hakakā a hoʻomaʻalili pono i ka ʻoki ʻoki.
ʻO nā mea mīkini me nā degere like ʻole o ka palupalu a me ka paʻakikī
No nā mea me ka paʻakikī a me ka ikaika o ka mīkini kiʻekiʻe, pono ke koho i kahi kihi hoʻomaha eccentric mai ka ʻoki ʻoki.
No ka laʻana, i ka hana ʻana i nā mea kila kila, hoʻohana ʻia kahi helical groove me kahi kihi rotation liʻiliʻi no ka hoʻokō ʻana i nā ʻano hana paʻakikī a paʻa o ke kila kila, i mea e hoʻomaʻamaʻa ai i ka ʻoki lōʻihi a me ka wehe ʻana i nā puʻu makapō.

Nā pilikia maʻamau i ke kaʻina o ka paʻi ʻana

Nui nā kumu no ka haʻihaʻi ʻana o ka paipa: ʻo nā mea hana mīkini, nā mea paʻa, nā mea hana, nā kaʻina hana, nā chucks, nā mea hana, a me nā mea ʻē aʻe, hiki ʻole ke ʻike ʻia ke kumu maoli ma ka pepa. Pono nā pilikia a pau i luna e hana i nā hoʻoholo a i ʻole nā ​​​​manaʻo i nā ʻenehana.
