S890QL Hoʻopiʻi ʻia a Hoʻohaʻahaʻa ʻia
Hoʻokumu wela
Hiki ke hana wela ma luna o 580°C. Pono e hana ʻia kahi quenching a me ka tempering e like me nā kūlana o ka lawe ʻana.
Milling
ʻO ka wili ʻana me nā kila māmā holo kiʻekiʻe HSSCO. Pono ka wikiwiki o ka ʻoki ʻana ma kahi o 17 - 19 m/min. Inā hoʻohana ʻia nā haʻawina HSS, ʻo ka wikiwiki o ka ʻoki ʻana ma kahi o 3 – 5 m/min.
ʻOki-Pā ahi
Pono ka mahana o ka mea ma lalo o RT no ka ʻoki ʻana i ke ahi. Eia hou, ua paipai ʻia nā mahana wela ma lalo nei no kekahi mau mānoanoa pā: No ka mānoanoa o ka pā ma luna o 40mm, hoʻomaʻamaʻa mua i 100°C a no nā mānoanoa ma luna o 80mm, hoʻomaʻamaʻa mua i 150°C.
wiliwili
He kūpono ke kila S890QL no nā ʻano hana kuʻi ʻana o kēia manawa. Pono ka mahana o ka mea ma lalo o RT no ka wili. Eia kekahi, ua ʻōlelo ʻia nā mahana preheating ma lalo nei no kekahi mau mānoanoa pā:
20mm – 40mm: 75°C
Ma luna o 40mm: 100°C
60mm a ʻoi aku: 150°C
ʻO kēia mau hōʻailona he mau waiwai maʻamau wale nō, ma ke kumu, pono e mālama ʻia nā hōʻailona o SEW 088.
Pono nā manawa t 8 / 5 ma waena o 5 a me 25 s, ma muli o ke ʻano hana kuʻi i hoʻohana ʻia. Inā pono ka hoʻoluhi hoʻoluhi ʻana i ke koʻikoʻi no nā kumu hana, pono e hana ʻia kēia ma ke ana wela o 530°C-580°C.
