簡介:平面(mian)刮(gua)刀(dao)是用來(lai)刮(gua)削或維修,機(ji)床,設備,平面(mian)等的(de)鏟刮(gua)工(gong)具,鉗工(gong)用來(lai)刮(gua)削金(jin)屬(shu)的(de)工(gong)具,刮(gua)刀(dao)一(yi)般(ban)為合(he)金(jin)頭(tou)刮(gua)刀(dao),硬度較.
名稱:刮研刀
別名:平面刮刀,鉗工刮研刀,鉗工刮刀,刮刀
刮研刀是用(yong)來刮(gua)(gua)削貨維修,機床,設備,平面等的鏟刮(gua)(gua)工(gong)具(ju),鉗工(gong)用(yong)來刮(gua)(gua)削金屬(shu)的工(gong)具(ju),一般(ban)為合金頭刮(gua)(gua)刀,硬(ying)度較。
用刮研刀以人工刮研方法修整工件平面度(du)(du),平行(xing)度(du)(du),粗糙度(du)(du)等,叫刮研或鏟刮。
平面刮刀通常機床的導軌,拖板,滑動(dong)軸(zhou)承(cheng)的軸(zhou)瓦都(dou)是用(yong)刮研的方法作精(jing)加工(gong)而成的.,
刮研是(shi)平(ping)面(mian)(mian)光整加工(gong)(gong)的(de)(de)(de)方法之一.其目的(de)(de)(de)是(shi)為了(le)降低表(biao)面(mian)(mian)粗糙度值,提接(jie)觸精(jing)度和幾何精(jing)度,從而提機床的(de)(de)(de)配合剛(gang)度,潤(run)滑性能,機械效益和使(shi)用(yong)壽命,也是(shi)僅用(yong)平(ping)面(mian)(mian)磨床和導軌磨床加工(gong)(gong)難以(yi)達到(dao)的(de)(de)(de),機床設備和鑄鐵平(ping)板(ban)所的(de)(de)(de)加工(gong)(gong)工(gong)(gong)藝.,
所謂(wei)"刮(gua)研(yan)",是(shi)刮(gua)削(xue)和(he)研(yan)磨(mo)(mo)兩個工序的結合.即(ji)平(ping)面(mian)(mian)刮(gua)削(xue)——研(yan)磨(mo)(mo)顯(xian)示,再平(ping)面(mian)(mian)刮(gua)削(xue)——再研(yan)磨(mo)(mo)顯(xian)示,如此往復,交(jiao)替循環,不(bu)斷(duan)運(yun)作.使鑄鐵平(ping)板的表面(mian)(mian)粗(cu)糙度(du)(du)值和(he)形位誤差逐(zhu)步降低;接觸精度(du)(du),幾(ji)何精度(du)(du)在運(yun)作中逐(zhu)步提(ti),直到達到規定要求為止。
