Qhov loj tshaj ntawm cov neeg kho tshuab NC kev noj mov thiab pneumatic NC kev noj mov yog qhov txawv ntawm kev so. Cov neeg kho tshuab NC siv cov khoom siv dag zog los so (yuav tsum khom ntawm lub punch slider), so kom txaus thiab tsis zuaj cov ntaub ntawv. Nws yog qhov yooj yim los kho thiab so ntawm qhov cuam tshuam sab nraud. Thaum koj xav so thaum koj sim rov hais dua cov pwm los yog cov ntaub ntawv, koj tsuas yog xav kom kho lub plhaub xoob los tuav lub Palin los so cov khoom. Lub lag luam yog yooj yim thiab yooj yim. Pneumatic NC feeder xaiv lub cylinder los rub tus menyuam rau ntawm lub pub rau kom tiav qhov kev so. Qhov txheej txheem no yuav tsum tau xuas xaum xauv xauv kom xa ib lub teeb tawm ntev mus rau lub voj voog solenoid, thiab cov solenoid valve yog siv los tswj cov tog raj kheej, kom lub NC pub dawb ncav cuag lub xeev. Yog li, pneumatic relaxation ntaus ntawv yog qeeb so, thiab tsuas yog cuam tshuam los ntawm lwm cov huab cua qhov chaw fais fab mov thiab cov khoom siv hluav taws xob, yog li ntawd lub pneumatic feeder tsis tau siv rau high-speed feeding, thiab kev lag luam kev hloov tseem raug kev ntxhov siab. Thaum sim rov qab noj cov pwm los sis hloov cov ntaub ntawv, vim hais tias cov txheej txheem xav tau cov ntaub ntawv ntau dua, lub pneumatic NC feeder yuav tsum tau so thiab tswj ntawm lub hwj chim tswj lub thawv txhua zaus nws tsis zoo. Qhov hloov tsis yog li yooj yim li mechanical.

Nyob rau hauv qhov kev yuav khoom, qhov kev xaiv thawj zaug raws li cov yam ntxwv ntawm lub tshuab punching, lub pneumatic NC feeder tsis xav kom nruab rau cov khoom ua haujlwm nyob rau hauv lub tshuab xuas nrig, yog li tsis muaj qhov teeb meem kev teeb meem, kev siv punch siv, thiab kuj tuaj yeem muab ntsia ua ke. Pub mus rau shearer los yog lwm yam khoom. Txawm li cas los xij, vim hais tias lub pneumatic relaxation yog qeeb, nws tsis haum rau kev ua haujlwm ceev ceev nrog cov kauj ruam luv luv. Mechanical NC feeder dais yuav tsum tau mechanically roded ntawm slider rau so, ces nws tsis haum rau kantry punching thiab shearing tshuab khoom, tab sis cov neeg kho tshuab relaxation muaj lus teb ceev, uas yog heev haum rau luv-theem high-ceev noj kev lag luam. Tshaj tej ntawm, kev kho kom zoo dua qub thiab kev yooj yim ntawm kev lag luam yog tseem zoo dua cov pneumatic NC cov fais fab.
