刀具的合理使用和选择将是影响数控加工质量的重要因素。硬质合金刀具被越来越广的应用，高速加工中涂层硬质合金将代替大部分锋钢刀具，包括铰刀、球头刀、镗刀等简单刀具，涂层硬质合金将在高速加工刀具材料中起到重要作用，应用到常规大部分的加工优先域中。

通常我们知道在粗加工中我们会选用大直径的刀具进行加工，为节约成本和降低刀具制造难度，我们会采用机夹式硬质合金刀片 ，尽量使粗加工排屑多;在半精加工中采用高转速高进给的镶片刀具，使半精加工走刀快;

在精加工时尽量采用高精度圆头镜面刀片于硬质合金刀杆来保证刀具与刀杆的强度，这样将可在保正加工精度的同时节省选用整体合金刀具的昂贵费用。在加工中我们还需要注意精加工零件上的内轮廓圆角半径必须大于或等于刀具的半径，选用半径小于拐角处圆角半径的刀具以圆弧插补的方式或斜线插补的方式进行加工，这样可以避免采用直线插补而出现过切现象，保证模具精加工质量。

 

　　希望上面给大家介绍的加工中心在加工模具的过程中注意选择合适的刀具，可以给大家带来帮助。

The rational use and choice of cutting tools will be the important factors affecting the quality of nc machining. Carbide tool is more and more widely used, high speed machining coated carbide will replace most of the steel cutting tools, including reamer, ball head knife, boring tool and other simple tools, coated carbide will play an important role in high speed machining tool materials, applied to most of the conventional processing fields.

 

Usually we know that in rough machining we will choose large diameter of the tool for processing, in order to save costs and reduce the difficulty of tool manufacturing, we will use machine clamped carbide blade, as far as possible to make rough machining chip discharge more; The insert cutter with high rotation speed and high feed is used in semi-finishing, which makes the semi-finishing run faster.
