Iimpawu kunye noKhetho lwe-Insert Bits

Iimpawu kunye nokukhethwa kwamasuntswana okufaka isalathisi

I-intest indexable bit, eyaziwa ngokuba yi-shallow hole drill okanye i-U drill, sisixhobo esisebenzayo sokwemba imingxuma enobunzulu bemingxuma engaphantsi kwamaxesha amathathu. Isetyenziswe ngokubanzi kwizixhobo ezahlukeneyo zoomatshini be-CNC, amaziko omatshini kunye ne-turret lathes kwiminyaka yakutshanje. kwi. I-drill bit idla ngokuxhonywa ngokulinganayo kunye nokufakwa kwesalathisi ezibini ukwenza imiphetho yangaphakathi nangaphandle, ecutshungulwa ngaphakathi komngxuma (kubandakanywa neziko) kunye nangaphandle komngxuma (kubandakanywa nodonga lomngxuma), njengoko kubonisiwe kwitheyibhile elandelayo. Xa ububanzi bomngxuma bukhulu, ii-blades ezininzi zingafakwa.

1. Ukuhlelwa kwemveliso I-indexable install bits ingahlelwa ngokwemilo ye-blade, imilo yefluti, isakhiwo, kunye neempawu zokucubungula.

(1) Ngokwemilo yencakuba, inokwahlulwa ibe ngunxantathu, unxantathu oyiconvex, idayimani, ihexagon, njalo njalo.

(2) Ngokutsho kwefleyiti eqhelekileyo yokusika, inokohlulwa ibe ziindidi ezimbini: umjelo othe tye kunye nomjelo ojikelezayo.

(3) Ngokwendlela yokubamba i-drill, inokwahlulwa ibe ziindidi ezimbini: umqheba wecylindrical kunye ne-Morse taper bit.

(4) Ngokolwakhiwo, lunokwahlulwa lube ziindidi ezintathu: uhlobo oludityanisiweyo, uhlobo lwemodyuli kunye nentloko yomsiki kunye nomzimba womsiki owahlukileyo wohlobo lwe-drill.

2, iimpawu zemveliso

(1) Ifanelekile ukusika isantya esiphezulu. Xa umatshini wensimbi, isantya sokusika iVc yi-80 - 120m / min; xa ugubungela i-blade, isantya sokusika iVc yi-150-300m / min, ukusebenza kakuhle kwemveliso ngamaxesha angama-7-12 we-standard twist drill.

(2) Umgangatho ophezulu wokucubungula. Ixabiso lomphezulu woburhabaxa linokufikelela kuRa=3.2 - 6.3 um.

(3) Iblade inokufakwa kwisalathiso ukuze konge ixesha elincedisayo.

(4) Ukuqhekeka kwe-chip elungileyo. Itafile yokuqhawula itshiphu isetyenziselwa ukuqhekezwa kwetshiphu, kwaye ukusebenza kokukhupha itshiphu kulungile.

(5) Isakhiwo sokupholisa sangaphakathi samkelwa ngaphakathi kwe-drill shank, kwaye ubomi be-drill blade buphezulu.

(6) Inokusetyenziswa kungekuphela nje ukomba kodwa kwanokukruqula nokukruqula. Kwezinye iimeko, inokusetyenziswa njengesixhobo sokuguqula.
