图1所示机夹不重磨端铣刀的结构,比一般机夹不重磨端铣刀紧凑、简单,适于制成密齿结构。刀片径向、轴向的定位,靠锥面和刀体槽,采用内六方螺钉拉紧圆柱销以楔面压紧。选用经研磨和刃磨的313或P3XH13三角形刀片。实践证明这种结构效果较好,可提高工效2～3倍,加工表面光洁度可达 5～6。刀具几何角度:可根据加工要求,选择主偏角为60°、75°、90°等(见图2～图4)。径向前角γ选用负值,按铣刀直径大小和加工情况来定。γ=arcsin
The structure shown in Figure 1 is not heavy end milling cutter folder than the average folder is not re-end milling cutter compact, simple, suitable for making tooth structure. Radial blade, the axial positioning, by the cone and the body slot, with hexagonal screws to tighten the cylinder pin to wedge surface compression. Use a ground or sharpened 313 or P3XH13 triangular blade. Practice has proved that this structure is better, can improve ergonomics 2 to 3 times, processing surface finish up to 5-6. Tool geometry angle: According to processing requirements, select the main declination angle of 60 °, 75 °, 90 °, etc. (see Figure 2 ~ Figure 4). Radial rake angle γ use a negative value, according to milling cutter diameter and processing conditions to be. γ = arcsin
