用蘑菇头螺钉3把刀片5压紧在刀片槽内。蘑菇头螺钉必须具有足够的硬度和强度,螺纹根部须有圆弧圆滑连接(图2)。 [结构特点] 夹紧力大,压紧可靠,带定位孔和不带定位孔的刀片都适用。这种结构经常用于粗加工或切削力变化较大的条件下。 [应用范围] 用在C630车床上,刀片材枓为YT15;加工40Cr材料。 [切削用量] v=120～200米/分; s=0.2～0.6毫米/转; t=0.2～7.5毫米。 [使用效果] 比焊接刀具提高效率一倍;刀具寿命提高1～2倍。
Use the mushroom head screw 3 blade 5 pressed in the blade slot. Mushroom head screws must have adequate hardness and strength, and the root of the threads must be rounded and rounded (Figure 2). [Structural features] clamping force, reliable compression, with and without positioning hole positioning holes are suitable for the blade. This structure is often used for roughing or cutting conditions under the conditions of large changes. [Applications] Used in C630 lathe, blade 枓 YT15; processing 40Cr material. [Cutting amount] v = 120 ~ 200 m / min; s = 0.2 ~ 0.6 mm / rev; t = 0.2 ~ 7.5 mm. [Effect] Doubled the efficiency of welded tools; Tool life increased by 1 to 2 times.
