Kodi makina opera ndi otani?

Makina opera ndi mtundu wa chida chamakina chomwe chimagwiritsidwa ntchito kwambiri, makina opera amatha kukonza ndege (yopingasa, yoyimirira), groove (keyway, T groove, dovetail groove, ndi zina zotero), ziwalo za mano (giya, spline shaft, sprocket), spiral surface (ulusi, spiral groove) ndi malo osiyanasiyana. Kuphatikiza apo, ingagwiritsidwenso ntchito popanga ndi kudula pamwamba ndi dzenje lamkati la thupi lozungulira. Makina opera akagwira ntchito, workpiece imayikidwa patebulo logwirira ntchito kapena zowonjezera zoyamba, mphero yozungulira ndiyo kayendetsedwe kake, kowonjezeredwa ndi kayendedwe ka chakudya cha tebulo kapena mutu wopera, workpiece imatha kupeza malo ofunikira opangira. Chifukwa ndi kudula kosalekeza kwa m'mphepete mwambiri, kotero kupanga bwino kwa makina opera kumakhala kwakukulu. Mwachidule, makina opera ndi chida chamakina chopangira mphero, kuboola ndi workpiece yosasangalatsa.

Mbiri ya chitukuko:

Makina opera ndi makina oyamba opera opingasa omwe adapangidwa ndi American E. Whitney mu 1818. Pofuna kupera mzere wozungulira wa twist bit, American JR Brown adapanga makina oyamba opera ozungulira mu 1862, omwe anali chitsanzo cha makina opera onyamulira tebulo lonyamulira. Cha m'ma 1884, makina opera opera opangidwa ndi gantry adawonekera. M'ma 1920, makina opera opangidwa ndi theka okha adawonekera, ndipo tebulo limatha kumaliza kusintha kwa "feed - fast" kapena "fast - feed" pogwiritsa ntchito choyimitsa.

Pambuyo pa 1950, makina opukutira mphero mu makina owongolera adapangidwa mwachangu kwambiri, kugwiritsa ntchito makina opukutira mphero kunasintha kwambiri kuchuluka kwa makina opukutira mphero. Makamaka pambuyo pa zaka za m'ma 70, makina opukutira mphero a microprocessor ndi makina osinthira zida zodziyimira pawokha akhala akugwiritsidwa ntchito mu makina opukutira mphero, kukulitsa kuchuluka kwa makina opukutira mphero, kukulitsa kulondola ndi magwiridwe antchito.

Ndi kuwonjezereka kwa njira zopangira makina, mapulogalamu a NC anayamba kugwiritsidwa ntchito kwambiri pakugwiritsa ntchito zida zamakina, ndipo anthu ogwira ntchito anamasuka kwambiri. Makina opangira mapulogalamu a CNC pang'onopang'ono adzalowa m'malo mwa ntchito yamanja. Zidzakhala zovuta kwambiri kwa antchito, ndipo ndithudi zidzakhala zogwira mtima kwambiri.
