我厂铣削加工深槽形零件数量较多,且槽形宽度及光洁度要求较高。采用普通三面刃铣刀加工,刀具磨损较大,零件尺寸不稳定,光洁度较差。为此,设计制造了可调机夹三面刃铣刀。经使用证明,调整方便,效率高,加工尺寸稳定,刚性好,使用寿命长。刀具结构如图1～5所示。根据加工槽形零件宽度、深度,将铣刀分为φ130×10、φ150×15两类, I mill deep groove-shaped parts more, and the groove width and finish requirements are higher. Using ordinary three-sided cutter processing, tool wear larger, unstable parts size, poor finish. To this end, the design and manufacture of adjustable folder three-sided cutter. Proved by the use, easy adjustment, high efficiency, stable processing size, good rigidity, long service life. Cutter structure shown in Figure 1 ~ 5. According to the processing of groove-shaped parts width, depth, the cutter is divided into φ130 × 10, φ150 × 15 two categories,
