钻头测量卡板是一种检查钻头几何角度和刃磨质量的专用量具。它能代替目前常用的万能角尺,圆弧卡规、深度尺等量具和一些专用量具。我厂曾自己制作过钻头测量卡板,使用方便,经久耐用,解决了刃磨和使用钻头时的许多实际问题,成为孔加工中检验钻头切削部分用的不可缺少的专用量具。制作时,卡板厚度按卡板大小而定,一般约3～3.5mm。材料为45钢,调质处理,或低碳钢(20、20Cr)渗碳、硬度HRC56～62,或碳素工具钢T8A、T10A。亦可选用锰钢、合金钢,以保持硬度。如无条件在铣床上拉刻度值时,可采用简便办法,即利用一段钢卷尺,用无机粘结剂把它贴在卡板角度边上,粘结面要
Drill measuring card board is a special tool to check the drill bit geometry and grinding quality. It can replace the commonly used universal square, arc card gauge, depth gauge and other measuring tools and some special measuring tools. Our factory has made its own bit measuring card board, easy to use, durable, to solve the sharpening and the use of many of the practical problems when the drill bit, hole processing to check the cutting part of the drill with the indispensable special measuring tools. Production, the thickness of the card board card size may be, usually about 3 ~ 3.5mm. Material 45 steel, quenched and tempered, or low carbon steel (20,20 Cr) carburization, hardness HRC56 ~ 62, or carbon tool steel T8A, T10A. Can also use manganese steel, alloy steel, in order to maintain the hardness. Unconditionally pull the scale value in the milling machine, you can use a simple method, that is, the use of a section of steel tape measure, with inorganic adhesive paste it in the card edge angle, the bonding surface to
