Hoʻohana ʻia nā mea wili kāʻei no nā mea palahalaha, poepoe a ʻāwili a me nā huahana liʻiliʻi. Hoʻokaʻawale ʻia lākou i loko o nā mīkini wili ākea, kūpaʻa a me nā mīkini wili profile.
Kiʻi 1: Mīkini hao me ka movable table brand Š1 PS.
Hoʻokaʻawale ʻia nā mea wili ākea i nā mīkini me kahi paʻa paʻa a me ka papa ʻaina hoʻoneʻe. Hoʻohana ʻia nā mea wili me kahi pākaukau paʻa no ka wili ʻana i nā mea liʻiliʻi, a me nā mea wili me kahi papa hoʻoneʻe no nā mea nui, panels, puka, hoʻopiha, veneer a me nā mea hou aku.
Hoʻohana ʻia nā wili kāʻei kūpaʻa no ka wili ʻana i nā kihi o nā mea, nā pahu, nā mea pōʻai a me nā mea hou aku.

Disc a me nā mea wili hui
Hiki ke hoʻolako ʻia nā mea wili disc me ʻelua mau papa wili i hoʻonohonoho ʻia a i ʻole me hoʻokahi pā wili i hoʻonoho ʻia ma ke ākea.

Hoʻohana ʻia ka sander disc me hoʻokahi pā no ka sanding angular a no ka hoʻolele ʻana i nā huahana liʻiliʻi me nā wahi liʻiliʻi. Hoʻohana liʻiliʻi ʻia nā mea wili disc me nā papa ʻelua.

Profile a me nā mea wili cylindrical
Hoʻohana ʻia nā mea wili profile no ka wili ʻana i nā mea profiled. Aia lākou i kahi spindle me kahi poʻo hana kahi i hoʻokomo ʻia ai me ka lole sanding a puni ka perimeter. I ka wā o ka hana ʻana, hoʻopili nā mea hoʻokomo i ka lole sanding i ka ʻaoʻao o ka mea.
Hoʻokaʻawale ʻia nā mea wili cylindrical i hoʻokahi-cylinder, ʻelua-cylinder, ʻekolu-cylinder a me ʻeono-cylinder, me ka manual a me ka mechanical displacement. Hana ʻia ka neʻe lima ma luna o nā mea wili pahu hoʻokahi, i hoʻohana pinepine ʻia no nā mea me nā ʻaoʻao curved, e like me nā profile arched.
Hoʻohana ʻia nā mea wili pahu multi-cylinder me ka hoʻoneʻe mechanical no ka wili ʻana i nā papa, veneers a me nā papa. Hiki ke hana ʻia ka neʻe ʻana ma o ka roller a i ʻole ke kāʻei conveyor rubber. Hoʻohana ʻia ka hoʻoneʻe ʻana me ka roller i ka wā e hoʻoneʻe ai i nā veneers, a me ka neʻe ʻana e ke kāʻei conveyor i ka wā e hoʻoneʻe ai i nā panela, nā puka a me nā papa.
ʻO nā cylinders o nā mīkini sanding he paipu kila me nā mea hoʻohui no ke kaulike a me ka hoʻopaʻa ʻana i ka lole ʻili. Hiki iā lākou ke holoʻokoʻa aʻokiʻoki paha. Hoʻopili ʻia ka lole sanding ma luna o ka cylinder holoʻokoʻa i kahi spiral a hoʻopaʻa ʻia ma ke alo o ka cylinder me kahi mea paʻa paʻa kūikawā. Ma ka ʻoki ʻia ʻana o ka ʻili, hoʻopaʻa ʻia ka lole ʻili i loko o ka slot ma ka ʻaoʻao o ka pahu.
He kūpono nā cylinders holoʻokoʻa no ka hoʻopaʻa ʻana i ka lole sanding a maʻalahi ke kaulike. Hiki ke loaʻa iā lākou ma luna a ma lalo paha o ka mea i hoʻopaʻa ʻia, me ke kūlana kiʻekiʻe e ʻōlelo ʻia he ʻoi aku ka maikaʻi. Ma waho aʻe o ka neʻe ʻana o ka rotary, neʻe like nā cylinders i ko lākou axis, approx100o na hahau papalua i ka minute ke hele mai10 mm. Hiki ke hoʻomaka ʻia ka cylinder e kahi kāʻei hoʻouna a i ʻole nā mokini uila i kūkulu ʻia.
ʻO nā mea wili me ka luna a i ʻole ke kūlana haʻahaʻa wale nō o ka cylinder e koi i nā mea e hoʻohele ʻelua i ka wā wili ʻaoʻao ʻelua. ʻO nā mea wili pahu ʻeono me nā kūlana kiʻekiʻe a me lalo e wili i nā ʻaoʻao ʻelua o ka mea i hoʻokahi ala.

ʻO ka kikokikona e ʻōlelo ana i kahi mīkini wili ʻekolu-cylinder me ka neʻe ʻana o ke kāʻei Š1 ZC (kiʻi 3), i manaʻo ʻia no ka wili nui ʻana i nā mea papa pālahalaha a me nā papa me ka laulā a hiki i 1.300 mm a me ka lōʻihi liʻiliʻi. 200 mm.

Ka lole ʻala a me ka nui o ka ʻili
Hoʻohana ʻia kahi lole abrasive ma ke ʻano he abrasive, ʻo ia ka pepa a i ʻole ka lole pulupulu kahi i hoʻopili ʻia ai nā hua ʻoi o nā mea paʻakikī. Hoʻopaʻa inoa ʻia nā lole wili me nā kīʻaha aniani, flint, quartz, corundum a me electrocorundum. Ma muli o ke koʻikoʻi o ka palaoa, hoʻokaʻawale ʻia nā lole ʻili i nā helu.
ʻO ka papaʻaina mua e helu i nā helu o ka lole sanding i hana mua ʻia ma USSR:
