Kana mainjiniya nevatengi vakataura nezvekushandisa DIN 333 center drill, mumwe wemibvunzo yatinowanzo bvunzwa ndewekuti: "Ndeupi musiyano uripo pakati peType A neType B — uye ndeupi wandinonyatsoda?"
Mubvunzo wakanaka. Mhando dzese dziri mbiri dzine angle yakafanana ye60° chamfer, dzinotevera DIN 333 standard yakafanana, uye dzinowanikwa muzvinhu zvakafanana. Asi pane musiyano wakakosha pakati padzo — uyo une chekuita zvakananga nekuti gomba rako repakati rinomira sei panguva yekugadzirwa.
Gwaro iri rinotsanangura musiyano wacho zvakajeka, nematafura eDIN 333 emhando dzese dziri mbiri.
Chii chinonzi DIN 333 Center Drill?
Chibooreso chepakati — chinonziwo chibooreso chakabatanidzwa uye chisinki chepakati — chinoshandiswa kugadzira gomba rakanyatsojeka re60° pamucheto wechinhu chebasa risati ratenderedzwa pakati penzvimbo uchishandisa lathe. Gomba repakati rinopa nzvimbo yakagadzikana yekugara pakati pechiso chepamberi, zvichiita kuti pave nekudzikama uye kururama kwenzvimbo panguva yekutendeuka, kukuya, kana kugaya.
DIN 333 ndiyo standard yeGerman (Deutsches Institut für Normung) inodzora geometry, saizi, uye kushivirira kwe60° centre drills. Inotsanangura mhando nhatu: Type A, Type B, uye Type R. Chinyorwa chino chinotarisa pamhando mbiri dzinonyanya kutsanangurwa: A naB.

Sarudzo dzeZvinhu: M2 vs. M35
Zvese zviri zviviri zvemhando A nerudzi B zvinowanikwa mumhando mbiri dzeHSS. Sarudzo yezvinhu haienderane nerudzi rwazvo — zvinoenderana nechinhu chebasa uye huwandu hwekugadzira.
M2 HSS — Giredhi Rakajairika
M2 (HS6-5-2) ndiyo HSS grade inoshandiswa zvakanyanya pasi rose. Inopa kusimba kwakanaka, kuramba kupfeka kwakavimbika, uye kushanda kwakasimba pazvinhu zvakasiyana-siyana zvebasa — simbi isina kusimba, aruminiyamu, simbi yakakandwa, mhangura, uye simbi zhinji dzisina ferrous. M2 centre drills ndiyo sarudzo yakajairika yenzvimbo dzese dzekugadzira.
M35 HSS-Co — Giredhi reCobalt reZvikumbiro Zvinoda Kuda
M35 (HS6-5-2-5, inozivikanwawo seHSSCo5) inowedzera 5% cobalt kuchigadziko cheM2. Izvi zvinosimudzira kudzivirira kupisa kusvika pa630–650°C uye zvinowedzera kuomarara kusvika 63–66 HRC. M35 ndiyo mhando inodiwa kana uchiisa simbi isina ngura pakati, simbi ye alloy, kana zvimwe zvinhu zvakaoma kushandisa muchina, kana mukugadzirwa kwemidziyo yakawanda uko hupenyu hwemidziyo huri chinhu chinonyanya kukosha.
Sarudzo dzeKupedzisa Pamusoro
Maitiro Ekusarudza: Gwaro Resarudzo Rinoshanda
Kana uri kuisa pakati pechinhu chinotenderedzwa ipapo ipapo muchimiro chimwe chete, Type A ndiyo sarudzo chaiyo. Iri nyore, ipfupi zvishoma, uye inofukidza ruzhinji rwemashandisirwo e lathe centering.
Kana maitiro ako achisanganisira chero chipi zvacho chezvinotevera, tsanangura Type B:
• Chishandiso chinofamba pakati pemichina kana kuchinjana pakati pekushanda
• Zvikamu zvinochengetwa kana kubatwa mushure mekuiswa pakati uye usati watenderedza kekupedzisira
• Kushivirira kwako kunoda kuti gomba repakati rirambe richidzokororwa panguva imwe chete.
• Uri kushanda nemashaft akanyatsogadzirwa uko mvura inoyerera kubva mugomba repakati rakakuvara isingagamuchirwi
Kana usina chokwadi, Type B ndiyo nzira yakachengeteka. Chamfer yekudzivirira haiwedzere kuoma pakuboorwa kwayo — inongoita kuti nzvimbo yekugara irambe yakachena.

KuJiacheng Tools, tinogadzira madhiri eDIN 333 pakati pemhando A neType B, anowanikwa mumhando yeM2 neM35 ane ruvara rwakajeka kana kuti TiN coating. Madhiri ese ari pakati pemhando iyi akagadzirwa zvizere kubva pamatanda akasimba, ane body tolerance h7, pakati pemadhayamita epilot kubva pa1.00mm kusvika 12.50mm (Type A) uye 1.00mm kusvika 6.30mm (Type B).
Zvigadzirwa zveOEM nemazita epachivande zviripo. Tinoshanda nevatengesi pasi rese muzvikamu zvemotokari, zvemuchadenga, zveinjiniya, uye zvekushandisa maturusi. Kana uchida kusimbisa zvinodiwa, kukumbira sampuro, kana kukurukura nezvehukuru hwakagadzirwa, taura nechikwata chedu panhamba iyi.joeyzhu@jiachengtoolsco.comkana kushanyawww.jiachengtoolsco.com.
