Product Overview
Optimize your core mold production and precision CNC machining lines with our heavy-duty 12mm 4 Flute HRC55 Solid Carbide End Mill. Engineered specifically for processing materials up to HRC55 hardness, this high-performance solid carbide cutter features an extended 45mm flute length and a 100mm overall length, delivering maximum axial reach for deep vertical pocketing, high-aspect-ratio slotting, and deep shoulder side milling.
Ground from premium micro-grain tungsten carbide substrate, the tool is integrated with an advanced, high-aluminum AlTiN (Bronze/Rose Gold) coating. This multi-layered coating delivers superb hot-hardness and oxidation resistance, effectively suppressing tool chatter, reducing harmonic deflection, and generating a flawless surface finish on alloy and pre-hardened steels.

Ibibazo
1) Ni ryari nshobora kubona igiciro?
Mubisanzwe twavuze mumasaha 24 tumaze kubona anketi yawe.Niba wihutirwa cyane kubona igiciro, nyamuneka uduhamagare cyangwa utubwire muri imeri yawe kugirango turebe ikibazo cyawe cyambere.
2) Nigute nabona icyitegererezo cyo kugenzura ubuziranenge bwawe?
Nyuma yo kwemeza ibiciro, urashobora gusaba ingero zo kugenzura ubuziranenge bwacu. Niba ukeneye gusa icyitegererezo cyo kugenzura igishushanyo mbonera hamwe nimpapuro, tuzaguha icyitegererezo kubuntu, mugihe cyose uguze ibicuruzwa byihuta.
3) Nshobora gutegereza kugeza ryari kubona icyitegererezo?
Nyuma yo kwishyura icyitegererezo hanyuma ukatwoherereza dosiye zemejwe, ibyitegererezo bizaba byiteguye gutangwa muminsi 3-7. Ibyitegererezo bizoherezwa ukoresheje Express hanyuma bigere kumunsi wakazi 3-7. Urashobora gukoresha konte yawe yihariye cyangwa ukatwishura niba udafite konti.
4) Gahunda yose ikorwa kugeza ryari?
Nyuma yo gutumiza, igihe cyo gutunganya umusaruro ni iminsi 20-25. Dukeneye iminsi 7 yo gutegura ibintu byose hanyuma iminsi 15 yo gukora.
5) Bite ho itariki yo gutwara no gutanga?
Mubisanzwe dukoresha ibyoherejwe kugirango duhindure ibicuruzwa.Ni iminsi igera kuri 7-25. Biterwa kandi na coutry hamwe nicyambu urimo.Bishobora kuba bigufi mugihe ukeneye kohereza ibicuruzwa nka Aziya. Niba haribintu byihutirwa dushobora kohereza ibicuruzwa dukoresheje indege ya Express, mugihe cyose wishyuye amafaranga yumuhanda.
6) Urimo gucuruza sosiyete cyangwa manufaturer?
Turi abanyamwuga. Ntabwo dufite uruganda rwibikoresho gusa, ahubwo dufite uruganda rwa sima.
7) Uruganda rwawe ruherereye he?
Turi mu mujyi wa Zhuzhou, Intara ya Hunan., Tungsten carbide base of China
8) Nshobora gutegereza kugeza ryari kubona icyitegererezo?
Nyuma yo kwishyura icyitegererezo hanyuma ukatwoherereza dosiye zemejwe, ibyitegererezo bizaba byiteguye gutangwa muminsi 3-7. Ibyitegererezo bizoherezwa ukoresheje Express hanyuma bigere kumunsi wakazi 3-5. Urashobora gukoresha konte yawe yihariye cyangwa ukatwishura niba udafite konti.
9) Bite ho ububiko bwawe?
Dufite ibicuruzwa byinshi mububiko, ubwoko busanzwe nubunini byose biri mububiko.
10) Kohereza kubuntu birashoboka?
Ntabwo dutanga serivisi yo kohereza kubuntu. Turashobora kugira igiciro niba uguze ibicuruzwa byinshi
