style="text-indent:25px">減薄機采用真空吸盤，硅片等脆性材料要求減薄厚度在微米之間，很容易損壞，甚至可能在磨削過程中已經(jīng)損壞，很難磨削達(dá)到要求。并且硅片、蘭寶石在磨削過程中產(chǎn)生熱量比較小，它們本身自帶散熱性，而陶瓷片等不具有散熱性或散熱性很小，片子磨削較薄，在磨削產(chǎn)生熱量和冷卻過程中，由于表面和內(nèi)部產(chǎn)生溫差，膨脹程度不同而形成過大的內(nèi)應(yīng)力，將會引起片子的變形和損壞，減薄的片子本身材料脆，厚度薄，很難確保在厚度達(dá)標(biāo)的情況下保證片子完好無損。橫向減薄機可使工件加工厚度減薄到0.02mm厚而不會破碎。</p><div
