Iterambere na Tekiniki Yuburyo bwa Ceramic Yinjiza Ibikoresho

Iterambere hamwe na tekinike yibikoresho bya ceramic

Mu gutunganya, igikoresho cyahoze cyitwa "amenyo yakozwe mu nganda", kandi kugabanya imikorere yibikoresho ni kimwe mu bintu by'ingenzi bigena umusaruro wacyo, igiciro cy'umusaruro ndetse n'ubwiza bwo gutunganya. Kubwibyo, guhitamo neza ibikoresho byo gutema ibikoresho nibyingenzi, icyuma ceramic, hamwe nubushyuhe bwacyo buhebuje, kwambara no guhangana n’imiti, byerekana ibyiza ibikoresho gakondo bidashobora guhuza murwego rwo gukata byihuse no gukata ibikoresho bigoye-imashini, kandi ibikoresho nyamukuru byibyuma byubutaka ni Al na Si. Ibintu bikungahaye mubutaka bwisi birashobora kuvugwa ko bidashoboka kandi bitarondoreka. Kubwibyo, ibyifuzo byo gukoresha ibikoresho bishya byubutaka ni binini cyane.

Ubwa mbere, ubwoko bwibikoresho byubutaka

Iterambere ryibikoresho byubutaka byibanda ku kunoza imikorere yibikoresho gakondo byubutaka, gutunganya ibinyampeke, guhuza ibice, gutwikira, kunoza uburyo bwo gucumura no guteza imbere ibicuruzwa bishya, kugirango ubone ubushyuhe bwinshi, kwambara no kurwanya. Gukora neza cyane kandi birashobora guhuza ibikenewe byihuse byihuse. Henan Institute of Superhard Materials irashobora kugabanya ibikoresho byibikoresho bya ceramic mubice bitatu: alumina, nitride ya silicon na nitride ya boron (ibikoresho bya cubic boron nitride). Mu rwego rwo guca ibyuma, alumina ceramic blade na silicon nitride ceramic blade hamwe hamwe bita ceramic blade; mubikoresho bidakoreshwa mubyuma, ibyuma bya nitride ya cubic ni mubyiciro byinshi byibikoresho byubutaka. Ibikurikira nibiranga ubwoko butatu bwubutaka.

. Ifite imyambarire myiza yo kurwanya no kurwanya ubushyuhe, kandi ubushyuhe bwayo buhanitse ntabwo byoroshye guhuza cyangwa gufata imiti hamwe nicyuma. Kubwibyo, alumina ishingiye kuri ceramic ceramic ifite intera yagutse cyane, ikwiranye nicyuma nicyuma. Gutunganya byihuse umuvuduko wawo; kubera uburyo bwiza bwo guhangana nubushyuhe bwumuriro, burashobora kandi gukoreshwa mugusya cyangwa guteganya mugihe cyahagaritswe, ariko ntibikwiye gutunganyirizwa amavuta ya aluminiyumu, titanium alloys na niobium alloys, naho ubundi ikunda kwambara imiti.

. Irangwa no gukomera kwinshi, kwihanganira kwambara neza, kurwanya ubushyuhe bwiza no kurwanya okiside, kandi imiti yimiti iri hagati ya nitride ya silicon na karubone nicyuma ni nto, kandi ibintu byo guterana nabyo ni bike. Birakwiye kurangiza, kurangiza, kurangiza cyangwa kurangiza.

. Kurugero, Hualing cubic boron nitride igikoresho BN-S20 ikoreshwa mubyuma bikomye ibyuma, icyiciro cya BN-H10 gikoreshwa muburyo bwihuse bwo kurangiza ibyuma bikomye, icyiciro cya BN-K1 gitunganyirizwa ibyuma bikomeye, icyuma cya BN-S30 cyihuta cyo gukata ivu Ibyuma bifite ubukungu kuruta gushiramo ceramic.

Icya kabiri, ibiranga ibikoresho byubutaka

Ibiranga ibikoresho byubutaka: (1) kwihanganira kwambara neza; (2) ubushyuhe bwo hejuru, ubukana butukura; (3) tool durability is several times or even several times higher than traditional tools, reducing the number of tool changes during processing, ensuring Small taper and high precision of the workpiece to be machined; (4) not only can be used for roughing and finishing of high-hardness materials, but also for machining with large impact such as milling, planing, interrupted cutting and blank roughing; (5) When the ceramic blade is cut, the friction with the metal is small, the cutting is not easy to be bonded to the blade, the built-up edge is not easy to occur, and high-speed cutting can be performed.

Ugereranije no gushiramo karbide ya sima, iyinjizwamo ceramic irashobora kwihanganira ubushyuhe bwo hejuru bwa 2000 ° C, mugihe ibivanze bikomeye biba byoroshye kuri 800 ° C; ibikoresho bya ceramic rero bifite ubushyuhe buhanitse bwimiti kandi birashobora kugabanywa kumuvuduko mwinshi, ariko ibibi ni insimburangingo. Imbaraga no gukomera ni bike kandi byoroshye gucika. Later, boron nitride ceramics (hereinafter referred to as cubic boron nitride tools) were introduced, which are mainly used for turning, milling, and boring superhard materials. Ubukomezi bwa cubic boron nitride ikata ni hejuru cyane kuruta iyinjizwamo ceramic. Kubera ubukana bwayo, nanone yitwa ibikoresho bya superhard hamwe na diyama. Bikunze gukoreshwa mugutunganya ibikoresho bifite ubukana burenze HRC48. It has excellent high temperature hardness - up to 2000 ° C, although It is more brittle than cemented carbide blades, but has significantly improved impact strength and crush resistance compared to alumina ceramic tools. In addition, some special cubic boron nitride tools (such as Huachao Super Hard BN-K1 and BN-S20) can withstand the chip load of rough machining and can withstand the impact of intermittent machining and finishing. The wear and cutting heat, these characteristics can meet the difficult processing of hardened steel and high hardness cast iron with cubic boron nitride tools.
