I ka ʻoki ʻana i nā lau alumini me nā burrs, ʻekolu kumu nui. ʻO ka mea mua, pono e hōʻoia inā loaʻa nā pilikia maikaʻi o ka ʻili. ʻO ka lua, he lōʻihi ka hoʻohana ʻia ʻana o ka pahi ʻili, a ʻaʻole wikiwiki ka lihi o ka maka. I kēia manawa, pono e hoʻomaʻamaʻa.

ʻO nā kumu o ka burrs i ka wā e ʻeli ai:

ʻO ka mea mua, ʻo nā kumu o nā lau ʻike:

1. He kakaikahi loa na niho ma ka maka pahi.

2. ʻO ka maikaʻi o ka ʻili maka. ʻO nā pilikia maikaʻi o ka ʻili maka e hoʻihoʻi pinepine ʻia ka ʻili i ka hale hana no ka nānā ʻana i mea e loaʻa ai nā ʻāpana maikaʻi o ka ʻili maka, e like me: ke ʻano o ka niho hewa, ka ikaika o ka pūhaka, ʻokoʻa ke kiʻekiʻe o ka niho saw, ʻilihune. concentricity, etc., a pili pū kēia me ke ʻano o nā mea hoʻolako pahi ʻike e nānā ai nā mea kūʻai aku i ke kūʻai ʻana i nā lau ʻike, a me ka loaʻa ʻana o kahi mea hana ʻike maka. E pale ʻia ka hapa nui o kēia mau pilikia i ke koho ʻana i nā lau ʻike.

ʻO ka lua, nā kumu o nā mea hana:

1. ʻAʻole kūpono ka pololei o ka spindle i ka maʻamau.

2. ʻAʻole maikaʻi ka palahalaha o ka flange a i ʻole he mau mea ʻē aʻe. ʻO ia hoʻi ka mea e hana nei i nā ʻoihana he nui, no laila pono mākou e hoʻolohe.

3. ʻAʻole maikaʻi ka pololei o ka maka pahi. Pono kēia i ka mea hoʻolako lako e mālama pinepine i nā mea hana e pale ai i ia mau pilikia.

4. Hoʻokomo ʻia ka pahi ʻili i hope. ʻOiai he kakaikahi kēia pilikia, aia nō kekahi mau hihia.

5. ʻAʻole paʻa ka mea. Hiki pinepine kēia kūlana inā ʻaʻole maʻamau ke ʻano o ka mea.

6. ʻO ka paheʻe ʻana o ke kāʻei, haʻahaʻa loa ka māmā holo o ka ʻili.

7. He wikiwiki loa ka hānai mea hana. I kēia hihia, ʻoi aku ka maikaʻi o ka ʻimi ʻana i kahi mea hana pono a hilinaʻi. E wehewehe mua ʻia ka mālama ʻana i ka wā e hāʻawi ʻia ai ka lako.

ʻO ka hope, nā kumu waiwai:

He palupalu loa ka mea, hoʻoheheʻe ʻia ka ʻili, ʻeleʻele loa ka mea, a he deformed ka mea, ka hopena o ka sweeping ma hope o ke ʻoki ʻana, a me ka papa waiwai (kiʻekiʻe silicon alumina).
