一般人們還認為，CBN砂輪是不適于磨削低碳鋼一類軟材料的，因為這時產(chǎn)生的磨屑易使砂輪堵塞。但目前研究認為，陶瓷結合劑CBN砂輪可采取提高砂輪線速度，以形成細小的磨屑，再借助高壓噴射磨削液***磨屑，以及供給充足磨削液等措施，可防止砂輪堵塞。因此，CBN砂輪是可以磨削低碳鋼(硬度大于30HRC)一類軟材料的。但是，CBN砂輪也不是磨削任何材料都有效的。通常它不適于磨削硬質合金及硬質合金與鋼的組合件，此時用金剛石砂輪有更好的效果。石家莊青銅結合劑金剛石砂輪訂制</p><div

而帶動工件旋轉時由無心砂輪磨削，在磨削工件時表面質量較高，精度相對也很高，磨削中，選擇砂輪粒度也相當重要，粗粒度的無心磨砂輪往往用于粗磨 </p> <p> 加工，只能加工要求不算高的工件，一般在加工時為了加快磨削速度，對加工量較大的工件道加工都會采用這種方法，這是由于它加工速度比較快的特 </p> <p>

無心磨削是一種高生產(chǎn)率的精密加工方法，它是在無心磨床或帶有無心夾具的內(nèi)、外圓磨床上進行的。 </p> <p> <br /> </p> <p> 在外圓無心磨床上磨削工件外圓表面，叫做無心外圓磨削（或外圓無心磨削）；在帶有無心夾具的內(nèi)、 </p> <p> <br /> </p> <p> 外圓磨床上磨削工件內(nèi)、外表面，稱為支承式無心磨削。無心外圓磨削和支承式 </p> <p> 無心磨削統(tǒng)稱為無心磨削。高精度無心磨床的特點： </p> <p> 1 工件中心不固定。這是無心磨削所獨具的特點。 </p> <p> 2 工件自身定位。工件的磨削表面同時又是定位面，其原始誤差和磨后誤差會反映為定位誤差，因而影 </p> <p> <br /> </p> <p> 響到工件磨削點附近的形狀誤差。根據(jù)這一特點，有人認為就圓度和波紋度而言，無心磨削沒有定心磨 </p> <p> <br /> </p> <p> 削加工精度高，這是不確切的。因為在合理選擇幾何布局之后， </p> <p> 無心磨削具有主動成圓的功能。 </p> <p> 3 工件的運動是由砂輪、導輪和托板聯(lián)合控制的。工件運動的穩(wěn)定性，不僅取決于機床運動鏈，而且還 </p> <p> <br /> </p> <p> 與工件、導輪及托板的實際情況（如工件形狀、重量、導輪及托板的材料、表面狀態(tài)，機床形式）和采 </p> <p> <br /> </p> <p> 用的磨削用量、幾何布局有關。 </p> <p> 4 無心磨削容易實現(xiàn)生產(chǎn)過程的自動化。 </p> <p> <br /> </p> <p> <br /> </p><div
