1. ABS yog dab tsi? Nws cov qib zog yog dab tsi?
ABS (Acrylonitrile Butadiene Styrene) yog cov thermoplastic polymer tsim los ntawm peb lub monomers: acrylonitrile (chemical stability), butadiene (impact resistance), thiab styrene (rigidity). Nws cov qauv molecular confers ib tug tshwj xeeb sib npaug ntawm cov khoom: tensile lub zog ntawm 40-50 MPa, cuam tshuam lub zog mus txog 58 kJ / m², thiab zoo heev tshuaj tiv thaiv thiab hluav taws xob rwb thaiv tsev. Hauv cov ntawv thov kev lag luam, ABS tau dav siv hauv CNC machining (Computer Numerical Control) vim nws cov txheej txheem ua tau zoo, tshwj xeeb tshaj yog rau cov khoom uas xav tau siab -precision molding.
ABS Qib Qib (ABS Yas)
General-Lub Hom Phiaj ABS: Qhov no yog hom ABS feem ntau, siv rau cov ntawv thov txheem. Nws cuam tshuam qhov sib npaug ntawm qhov toughness, cuam tshuam tsis kam, thiab yooj yim ntawm kev ua.
Siab - Kub ABS: Tsim los rau cov ntawv thov uas xav tau kev ua haujlwm siab dua thermal. Qib no tuaj yeem tiv taus qhov kub siab dua yam tsis muaj deformation.
Siab -Ib puag ncig ABS: Cov txheej txheem muab kev tiv thaiv ntxiv thiab kev cuam tshuam, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom uas raug rau cov neeg kho tshuab tseem ceeb.
2. Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm ABS hauv CNC machining?
Qhov zoo
1) Cov khoom siv kho tshuab zoo heev: ABS sib txuas rigidity thiab toughness, ua kom nws tuaj yeem tiv thaiv kev txiav quab yuam tsis tawg thaum CNC machining ntawm ABS, ua rau nws tsim nyog rau kev tsim cov khoom siv xws li cov khoom siv hluav taws xob thiab cov khoom siv hauv tsheb.
2) Kev sib xyaw ua haujlwm zoo heev: Piv nrog rau lwm cov yas, ABS qhia tau zoo tshaj qhov cuab yeej hloov tau thaum lub sij hawm CNC milling ntawm ABS yas, ua rau siab - precision machining ( kam rau ua ± 0.05mm) los ntawm cov txheej txheem xws li milling, tig, thiab drilling, nrog ib tug siab deg tiav (Ra tsawg dua los yog sib npaug).
3) Tus nqi- zoo: ABS raw khoom tus nqi pheej yig (kwv yees li $ 2 / kg), thiab nws muaj kev ua haujlwm siab, ua rau nws tsim nyog rau cov qauv tsim thiab me me -batch ntau lawm hauv ABS yas machining, yog li txo cov nqi tsim khoom.
Qhov tsis zoo
1) Siab thermal rhiab heev: ABS muaj qhov melting point ntawm kwv yees li 190-220 degree. Thaum lub sij hawm ABS machining, yog hais tias qhov txiav ceev yog siab dhau (piv txwv li, tshaj 3000 rpm), kev sib txhuam-induced cua sov yuav ua rau cov khoom softening thiab cov cuab yeej adhesion. Nyob rau hauv cov ntaub ntawv no, coolant yuav tsum tau siv los tswj qhov kub thiab txias.
2) Tsis paub meej nyob rau hauv seem stability: nyias-walled qhov chaw (phab ntsa thickness<0.5 mm) may warp during machining due to the release of internal stress. Solutions include step-by-step machining or optimizing fixture support.
3. CNC Machining txheej txheem rau ABS
1) Milling:
Cov cuab yeej carbide (piv txwv li, 1/8" tiaj tus-kawg milling cutters) yog siv. Pom zoo txiav tsis: spindle ceev 15,000-18,000 rpm, pub tus nqi 1,000-1,500 mm/min. Thaum CNC milling ABS yas, siv cov txheej txheem nce milling zoo.
2) Kev xa tawm:
Tsim nyog rau ncej- hom qhov chaw, ib zaug - cov cuab yeej txiav yuav tsum tau siv. Optimize clamping txoj kev los tiv thaiv workpiece vibration. Txiav ceev yuav tsum tau tswj ntawm 800-1200 m / min.
3) Drilling thiab Tapping:
Siv cov ntse siab-ceev steel laum cov khoom ntawm qhov nrawm nrawm (1000-1500 rpm) nrog txiav cov kua dej los tiv thaiv cov phab ntsa ntxhib los ntawm kev kub dhau.
4) Kev kho deg:
Ncej- kev ua tiav tuaj yeem txhim kho cov tsos thiab kev ua tau zoo los ntawm kev sib tsoo, pleev xim, electroplating (xws li, metallization), thiab lwm yam, kom ua tau raws li ntau hom kev thov ntawm CNC machining ABS.
