Yuav ua li cas los txhim kho qhov precision ntawm yas pwm?
1. Pwm ua zoo suav nrog kev ua kom raug thiab qhov zoo ntawm qhov chaw
Machining raug yog qhov kev sib raug zoo ntawm qhov loj me, cov duab thiab txoj hauj lwm ntawm qhov chaw ntawm lub tshuab machined thiab qhov zoo tshaj plaws geometric tsis xav tau los ntawm daim duab.
Qhov zoo tshaj plaws geometric parameter, rau qhov loj, yog qhov nruab nrab loj; Rau qhov chaw geometry, nws yog lub voj voog meej, lub tog raj kheej, dav hlau, lub khob hliav qab thiab kab ncaj. Rau qhov kev sib nrig sib ntawm qhov chaw, nws yog kiag li thaum uas tig mus, ntsug, coaxial, symmetrical, thiab lwm yam. Qhov sib txawv ntawm qhov tseeb geometrical tsis thiab qhov zoo tagnrho geometrical parameters ntawm ib feem yog hu ua machining yuam kev.
Machining raug thiab machining yuam kev yog ob nqe lus siv los ntsuas cov geometric tsis ntawm machined nto. Machining raug yog ntsuas los ntawm qib kam rau ua, qhov tsawg dua tus nqi qib, qhov raug siab dua; Qhov yuam kev machining yog qhia los ntawm tus lej tus nqi, thiab qhov loj dua tus lej tus nqi, qhov loj dua qhov yuam kev. Kev ua haujlwm siab txhais tau tias ua haujlwm me me yuam kev, thiab rov ua dua.
Qhov tseeb tsis tau los ntawm txhua txoj kev ua yuav tsis raug kiag li, los ntawm kev ua haujlwm ntawm ib feem, tsuav yog qhov kev ua yuam kev nyob rau hauv qhov kev ua siab ntev xav tau los ntawm qhov kev kos duab, qhov kev ua tiav raug suav tias yog lav.
Qhov zoo ntawm lub tshuab yog nyob ntawm machining zoo ntawm cov khoom thiab kev sib dhos zoo ntawm lub tshuab. Lub machining zoo ntawm cov khoom suav nrog kev ua kom raug ntawm cov khoom thiab qhov zoo ntawm ob qhov chaw. Qhov tseeb machining yog hais txog cov degree uas qhov tseeb geometric tsis (loj, duab thiab txoj hauj lwm) ntawm cov khoom tom qab ua tau raws li qhov zoo tagnrho geometric tsis.
Qhov txawv ntawm lawv yog hu ua machining yuam kev. Qhov loj ntawm machining yuam kev qhia txog qhov machining precision. Qhov loj dua qhov yuam kev, qhov qis dua qhov tseeb ntawm machining, thiab qhov yuam kev me dua, qhov siab dua qhov tseeb ntawm machining.
2. Cov ntsiab lus tseem ceeb cuam tshuam rau kev ua haujlwm raug
2.1 Dimensional raug
Hais txog qhov kev sib haum xeeb ntawm qhov loj ntawm lub tshuab machined thiab qhov kam rau ua qhov chaw nruab nrab ntawm qhov loj. Dimensional raug yog tswj los ntawm dimensional tolerances. Dimensional kam rau ua yog qhov tso cai hloov pauv ntawm qhov loj ntawm ib feem thaum txiav. Nyob rau hauv cov ntaub ntawv ntawm tib qhov loj me me, qhov me me ntawm qhov ntev ntev thiab qhov siab dua qhov tseeb.
2.2 Cov duab raug
Nws hais txog qhov kev sib haum xeeb ntawm qhov tseeb geometry ntawm qhov chaw machined nto thiab qhov zoo tshaj plaws geometry. Muaj 6 yam khoom los ntsuas qhov tseeb, xws li ncaj, flatness, roundness, cylindricity thiab kab profile. Cov duab raug yog tswj los ntawm kev ua siab ntev, thiab txhua qhov kev kam rau ua tau muab faib ua 12 qhov tseeb tshwj tsis yog rau 13 qhov tseeb theem ntawm roundness thiab cylindricity. Qib 1 yog qhov siab tshaj plaws thiab qib 12 yog qhov qis tshaj.
2.3 Qhov tseeb ntawm qhov chaw
Hais txog qhov sib txawv ntawm qhov tseeb qhov tseeb ntawm qhov chaw ntawm cov khoom siv machined. Muaj yim yam khoom los ntsuas qhov tseeb ntawm txoj hauj lwm, xws li parallelism, perpendicularity, inclination, coaxiality, symmetry, txoj hauj lwm, round runout thiab tag nrho runout. Txoj hauj lwm raug yog tswj los ntawm txoj hauj lwm kam rau ua, uas tau muab faib ua 12 qhov tseeb.
