Mbiri Yachidule ya PDC Cutters

PDC, kapena polycrystalline diamondi yaying'ono, ocheka akhala osintha masewera pamakampani obowola. Zida zodulira izi zasintha ukadaulo wakubowola powonjezera mphamvu komanso kuchepetsa ndalama. Koma kodi ocheka a PDC anachokera kuti, ndipo anatchuka bwanji chonchi?

Mbiri ya ocheka a PDC idayamba m'ma 1950s pomwe diamondi zopangira zidapangidwa koyamba. Ma diamondi amenewa amapangidwa ndi kuyika graphite ku zovuta kwambiri ndi kutentha, kupanga zinthu zomwe zinali zolimba kuposa diamondi yachilengedwe. Ma diamondi opangidwa mwachangu adakhala otchuka m'mafakitale, kuphatikiza kubowola.

Komabe, kugwiritsa ntchito diamondi zopangira pobowola kunali kovuta. Ma diamondi nthawi zambiri amatha kusweka kapena kuchoka ku chidacho, kuchepetsa mphamvu yake komanso kumafuna kusinthidwa pafupipafupi. Pofuna kuthana ndi vutoli, ofufuza anayamba kuyesa kuphatikizira diamondi zopangidwa ndi zipangizo zina, monga tungsten carbide, kuti apange chida chodula komanso chogwira mtima kwambiri.

M'zaka za m'ma 1970, odula oyambirira a PDC anapangidwa, opangidwa ndi diamondi wosanjikiza womangidwa ndi tungsten carbide gawo lapansi. Odulawa poyamba ankagwiritsidwa ntchito m’migodi, koma phindu lawo linaonekera mwamsanga pobowola mafuta ndi gasi. Odula a PDC adapereka kubowola mwachangu komanso moyenera, kuchepetsa ndalama ndikuwonjezera zokolola.

Pamene luso lamakono likupita patsogolo, ocheka a PDC adakhala otsogola kwambiri, ndi mapangidwe atsopano ndi zipangizo zomwe zimawonjezera kulimba kwawo komanso kusinthasintha. Masiku ano, odula a PDC amagwiritsidwa ntchito pobowola osiyanasiyana, kuphatikiza kubowola kwa geothermal, migodi, zomangamanga, ndi zina zambiri.

Kugwiritsa ntchito odula a PDC kwadzetsanso kupita patsogolo kwa njira zobowola, monga kubowola mopingasa komanso kubowola kolowera. Njirazi zidatheka chifukwa cha kuchuluka kwa magwiridwe antchito komanso kukhazikika kwa odula a PDC, kulola kubowola kolondola komanso koyendetsedwa bwino.

Pomaliza, ocheka a PDC ali ndi mbiri yakale yochokera ku mapangidwe a diamondi opangidwa mu 1950s. Chisinthiko ndi chitukuko chawo chadzetsa kupita patsogolo kwambiri paukadaulo wakubowola, kukonza bwino, kuchepetsa ndalama, ndikukulitsa ntchito zosiyanasiyana. Pomwe kufunikira kobowola mwachangu komanso koyenera kukukulirakulira, zikuwonekeratu kuti odula a PDC akhalabe gawo lofunikira pakubowola.
