在机械加工中,去掉各种零件毛刺飞边,颇感棘手。为此,我们自制了如图所示的一套硬质合金多用刮刀,无论直边,曲线边,还是孔口,也不管是硬材料还是软材料,都能刮削。大有“两刀在手,毛刺不愁”之便。制作时单刃刀用YT15的切断刀即可磨成,双刃刀先用F_1型合金头磨成底面是正方形的长方体,然后照图2磨成,焊在30°弯柄上。双刃刀适宜刮削密封槽口的双棱毛刺。制作时,R_1、R_2取2～4mm为宜,β_1取30°～60°。β_2角取45°～60°。单刃刀头顶端,需磨成光滑的半圆
In machining, remove various parts burr flash, quite tricky. For this purpose, we made a self-made multi-purpose carbide scraper as shown in the figure, whether straight, curvilinear, or perforated, whether hard or soft. Great “two knives in hand, burr worry” of it. When making a single-edged knife with YT15 cutting knife can be ground into a double-edged knife first with F_1 alloy head grinding into the bottom is a square cuboid, and then grind into Figure 2, welded to 30 ° curved handle. Double-edged knife scraping seal slotted double-sided burr. Production, R_1, R_2 take 2 ~ 4mm is appropriate, β_1 take 30 ° ~ 60 °. β_2 angle take 45 ° ~ 60 °. Single-edged blade tip, to be polished into a smooth semicircle
