图1所示是一种结构简单、使用范围较广的铲齿刀具磨内孔夹具。它以刀具端面和齿顶后面为基准,装夹、磨削淬火后(或端面磨削后)铲齿片铣刀和滚刀的内孔,经过几年来在我厂的使用,效果良好。使用范围 (1) 内孔d≤32毫米,外径D为50～125毫米,刀具沟槽数Z=9、10、12的铲齿式片铣刀; (2) 模数为1～8的标准齿轮滚刀。 Shown in Figure 1 is a simple structure, the use of a wide range of shovel cutter grinding hole fixture. It is based on the tool end face and back of the tooth as a benchmark, clamping, grinding after quenching (or face grinding) after the blade cutter and hob inside the hole, after several years of use in our plant, the effect is good. Use range (1) D ≤ 32 mm bore, the outer diameter D is 50 ~ 125 mm, the number of tool grooves Z = 9,10,12 tooth scraping chip cutter; (2) modulus of 1-8 Standard gear hob.
