在刨削加工中,加工钢件(3号或15、35号等)要获得　　5以上的光洁度和0.04/1000毫米的平面平直性,比起加工铸铁件要费劲得多。 我厂生产的各式拉床的床身(机床)、床台、油箱都是3%钢板焊接件,在精刨过程中,往往因为刀具几何角度不耐磨,出屑不好经常出现不平和几何精度超差的缺陷 In the shaving process, the processing of steel (No. 3 or No. 15, No. 35, etc.) to obtain more than 5 and 0.04 / 1000 mm flat surface flatness than the cast iron pieces to be much more laborious. I plant all kinds of broaching machine bed (machine), bed, fuel tank are 3% steel welding parts, fine planing process, often because of the tool geometry does not wear, poor crumbs often appear uneven Geometric accuracy defects over
