鉆頭怎么磨好
檢查鉆頭(tou)是否(fou)(fou)彎(wan)曲(qu),刀菱(ling)口是否(fou)(fou)完(wan)好。靠近砂(sha)(sha)輪機(ji)(ji)(ji)砂(sha)(sha)輪的中(zhong)部以(yi)上(shang)的位置,并(bing)做上(shang)下運動。在另(ling)一臺專用開槽(cao)的砂(sha)(sha)輪機(ji)(ji)(ji)上(shang),把(ba)這個(ge)垂直于鉆頭(tou)中(zhong)線(xian)的橫向刀口在磨成尖。最后用打磨機(ji)(ji)(ji)打磨一下即可。
鉆頭規格
主要規格有(you)4、6、8、10、13、16、19、23、32、38、49mm等(deng)。以(yi)(yi)不同的鉆(zhan)(zhan)(zhan)(zhan)進(jin)方(fang)式(shi)為(wei)根據對鉆(zhan)(zhan)(zhan)(zhan)頭(tou)進(jin)行分類,可(ke)以(yi)(yi)將(jiang)其分為(wei)金(jin)(jin)剛石(shi)(shi)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)、牙輪鉆(zhan)(zhan)(zhan)(zhan)頭(tou)與刮刀鉆(zhan)(zhan)(zhan)(zhan)頭(tou)。以(yi)(yi)所適(shi)應地(di)(di)(di)層(ceng)的差異(yi)為(wei)根據,可(ke)以(yi)(yi)將(jiang)金(jin)(jin)剛石(shi)(shi)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)分為(wei)普通金(jin)(jin)剛石(shi)(shi)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)、聚(ju)晶金(jin)(jin)剛石(shi)(shi)復合片(pian)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)兩大類。在這兩大類之中(zhong),普通金(jin)(jin)剛石(shi)(shi)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)適(shi)用(yong)于(yu)研磨性較高、地(di)(di)(di)質(zhi)較硬(ying)、地(di)(di)(di)質(zhi)復雜的地(di)(di)(di)層(ceng);聚(ju)晶金(jin)(jin)剛石(shi)(shi)復合片(pian)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)能夠被廣泛(fan)的應用(yong)于(yu)硬(ying)質(zhi)地(di)(di)(di)層(ceng)、軟質(zhi)地(di)(di)(di)層(ceng)、軟硬(ying)適(shi)中(zhong)的地(di)(di)(di)層(ceng),其應用(yong)范圍十分廣泛(fan)。
鉆頭報價
市面上的鉆頭價格相差很大,一般來說價格都在十幾塊錢左右。此外,鉆頭品牌、種類(lei)、工藝都會影響鉆頭(tou)的價格。
麻花鉆是什么
麻花鉆(zhan)(zhan)是通(tong)過其相對固定(ding)軸線的(de)(de)旋轉切削以鉆(zhan)(zhan)削工(gong)(gong)件(jian)的(de)(de)圓孔的(de)(de)工(gong)(gong)具。因其容屑槽成螺旋狀而形似麻花而得名。螺旋槽有2槽、3槽或(huo)更多(duo)槽,但以2槽最為常見。麻花鉆(zhan)(zhan)可被夾持(chi)在(zai)手(shou)動、電動的(de)(de)手(shou)持(chi)式鉆(zhan)(zhan)孔工(gong)(gong)具或(huo)鉆(zhan)(zhan)床(chuang)、銑床(chuang)、車床(chuang)乃至加工(gong)(gong)中心上使(shi)用。鉆(zhan)(zhan)頭材(cai)料一般(ban)為高速工(gong)(gong)具鋼或(huo)硬質合金。
