He mea nui nā pahi ʻokiʻoki ʻoihana no ka ʻoki ʻana i nā mea resin, a ʻo ka pololei o nā pahi ʻokiʻoki e hoʻoholo pololei i ka waiwai o nā huahana. ʻO nā mea resin, ʻoi aku hoʻiPET a me PVC,Loaʻa i ka maʻalahi ke kūlou a me ka hoʻoheheʻe wela. Inā ʻaʻole lākou e ʻoki pono ʻia, he mea maʻalahi loa ke hana i nā burrs ma ka ʻoki, ka hoʻoheheʻe ʻana o ka mea a me ka pipili ʻana i ka mea ʻoki, ka deformation a me ka haki ʻana. ʻO ke ʻano o nā mea resin e hoʻopilikia pololei i nā noi hana i loko o ka hoʻopili ʻana, nā kaʻa, nā mea uila, nā optoelectronics, a me nā ʻoihana lapaʻau.
ʻO ke ʻoki ʻana ke kau ʻana i ke kaumaha kiʻekiʻe kūloko i nā pahi ʻokiʻoki i ʻoi aku ma mua o ka palena ikaika o ka mea resin, e hana ana iā ia e loli i ka plastic deformation, brittle fracture, a ma hope ka hoʻokaʻawale ʻana. E hoʻopilikia nā ʻano o ka mea resin i ka hopena maoli o ka ʻoki ʻana. ʻO ka resin paʻakikī (e like me PE, PP): ke kahe nui nei ka plastic, elongation, stretching, a me ka extrusion deformation. Hoʻokuke ʻia ka mea e ka lihi ʻokiʻoki a hōʻiliʻili i mua a ma nā ʻaoʻao ʻelua o ka lihi ʻokiʻoki. Brittle resin(e like me PS, PMMA)He liʻiliʻi loa ka ʻāpana hoʻololi plastik, a hilinaʻi nui ia i ka haki palupalu ma hope.
ʻO ka ʻaoʻao mua (ka ʻili pili me ka ʻāpana) a me ka ʻaoʻao hope (ka ʻili pili me ka ʻili i hana hou ʻia) o ka mea ʻoki e hamo ikaika me ka mea resin. Ke ʻoi aku ka mahana kūloko ma mua o ke kiko heheʻe o ka resin, palupalu ka mea a heheʻe paha. E pipili ka mea heheʻe i ka ʻili o ka mea hana, e hana ana i ka pipili, nā ʻūlū, nā ʻili ʻino, a me ka wikiwiki o ka ʻaʻahu ʻana o ka mea hana. He paʻakikī kiʻekiʻe nā mea fiber aniani/fiber kalapona a me ka friction wikiwiki, no laila pono ʻoe e hoʻohana i kahi mea ʻokiʻoki me ka paʻakikī ma mua o (90HRA) e hoʻonui i ke ola lawelawe.
Hoʻohana ʻo ShenGong Tungsten Steel i nā ʻāpana tungsten carbide maikaʻi loa(0.3-0.5μm)no ka hoʻoikaika ʻana i ka paʻakikī o ka pahi, e hoʻolālā i ka ʻoi ʻoki no nā mea like ʻole e hōʻoia i ka ʻoki ʻoi, a hoʻohana i ka uhi TiN e hōʻemi i ka adsorption o ka ʻili i hoʻokumu ʻia e ka friction. I ka manawa like, hiki ke hana ʻia nā hana e like me nā kūlana hana maoli.
No nā nīnau e pili ana i ka ʻoki ʻana i nā mea resin, e ʻoluʻolu e kelepona iā Shengong Tungsten Steel.
