style="text-indent:25px">由于力效應(yīng)和溫度效應(yīng)而引起金剛石圓鋸片的磨破損。力效應(yīng)：在鋸切過(guò)程中，鋸片要受到軸向力和切向力的作用。由于在圓周方向和徑向存在力的作用，使得鋸片在軸向呈波浪狀，在徑向呈碟狀。這兩種變形都會(huì)造成巖石切面不平直、石材浪費(fèi)多、鋸切時(shí)噪音大、振動(dòng)加劇，造成金剛石結(jié)塊早期破損、鋸片壽命降低。溫度效應(yīng)：傳統(tǒng)理論認(rèn)為：溫度對(duì)鋸片過(guò)程的影響主要表現(xiàn)在兩個(gè)方面：一是導(dǎo)致結(jié)塊中的金剛石石墨化；二是造成金剛石與胎體的熱應(yīng)力而導(dǎo)致金剛石顆粒過(guò)早脫落。新研究表明：切割過(guò)程中產(chǎn)生的熱量主要傳入結(jié)塊。磨削工具耐沖擊，適于粗磨和荒磨加工；東莞模具展會(huì)值得去看嗎</p><p
