Pdc, kana Polycrystalline Diamond compact, cutters ave ikaita mutambo-wecan indasitiri yekukwevera. Aya maturusi ekucheka akashandura kuchema kanulogy nekuwedzera kushanda zvakanaka uye kuderedza mari. Asi maPdc vatengi vePdc vachiri kupi, uye vakave vakakurumbira sei?
Nhoroondo yePDC Cutters inodzokera kuma1950s kana madhaimani ekugadzira akatanga kugadzirwa. Iyi madhaimani yakagadzirwa nekuenzanisa kugadziriswa kune yakanyanya kudzvinyirira uye kupisa, kugadzira zvinhu zvaive zvakaoma kupfuura madhaimani akasikwa. Synthetet madhaimani akakurumidza kuve akakurumbira mukushandisa maindasitiri, kusanganisira kuchera.
Nekudaro, kushandisa madhaimani ekuyananisa mukudhirowa zvaive zvakaoma. Madhaimani aiwanzo kupwanya kana kubvarura kubva pachishandiso, achideredza kushanda kwayo uye achida kudzoreredzwa. Kuti ugadzirise dambudziko iri, vaongorori vakatanga kuyedza nemadhaimani ekubatanidza nemimwe mimwe midziyo, senge tungsten chombo, kuti vagadzire chishandiso chakasimba uye chakaburitswa.
Muma1970s, iyo yekutanga PDC vatengi vakagadziriswa, inosanganisira dhaimani dhayamondi yakasungwa kune tungsten carbide substrate. Vatema ava pakutanga vanoshandiswa mune indasitiri yemugodhi, asi makomborero avo akakurumidza kunge achionekwa mumafuta uye egasi anokwevera gasi. PDC Cutters inopa nekukurumidza uye nekunyatsoita kurova, kuderedza mari uye kuwedzera kubereka.
Semunduku Nhasi, maPdc vatengi vanoshandiswa mune dzakasiyana siyana dzekuchera zvinhu, kusanganisira geothermal kuchera, mumigodhi, kuvaka, uye nezvimwe.
Iko kushandiswa kwePdc vatengi kwakatungamirawo kufambira mberi mukukwezva maitiro, sekudonha kwakakwenenzverwa uye kudhiraivha. Aya maitiro akaitwa anokwanisika nekuwedzera kugona uye kujaira kwePDC cutters, kubvumira kuti iwedzere kuomesa uye kudzorwa kucherwa.
Mukupedzisa, vatema vePCC vane nhoroondo yakapfuma yekufambidzana kudzokera mukuvandudzwa kwemadhaimani echiSynthetic kuma1950s. Kushanduka kwavo uye kukura kwavo kwakakonzera kufambira mberi kwakakura mukuchera matekinoroji, kuvandudza kushanda zvakanaka, kudzora mari, uye kuwedzera huwandu hwenyaya. Sezvo kudikanwa kwekukurumidza uye nekunyatsoita kurova kuchikurumidza kukura, zviri pachena kuti maPdc vatengi vanoramba vari chikamu chakakosha cheindasitiri yekukwevera.
