25吨电滚轮架衬套(图1),是一种薄壁件,由于这种件薄易变形,且批量又大,因此,我厂工人师傅针对这一问题,在学习兄弟厂先进经验的基础上,革新成功了简易薄壁套料刀(图2)。一、技术条件及切削用量 (1) 刀具材料;刀片为YT15硬质合金;刀体为45钢; (2) 使用机床;C618或C620普通车床; (3) 切削用量:切削速度V=50米/分;走刀量S=0.15～0.18毫米/转。二、刀具特点与使用效果 25 tons of electric roller carrier bushing (Figure 1), is a thin-walled parts, as this piece is easy to deform, and large quantities, so I plant workers master this problem, learning advanced experience in Brother plant Based on the successful renovation of a simple thin-walled nest knife (Figure 2). First, the technical conditions and the amount of cutting (1) tool material; blade YT15 carbide; body 45 for the steel; (2) the use of machine tools; C618 or C620 ordinary lathe; (3) cutting the amount of cutting speed V = 50 meters / Min; walking amount S = 0.15 ~ 0.18 mm / rev. Second, the tool features and the use of results
