Types of Milling Cutters
铣刀的类型
There is a wide variety of milling cutter shapes. Each of them is designed to perform effectively a specific milling operation.
铣刀的形状类型很多。其中每种都是为有效进行特定的铣削作业而设计的。
Generally, a milling cutter can be described as a multiedge cutting tool having the shape of a solid of revolution, with the cutting teeth arranged either on the periphery or on an end face or on both. Following is a quick survey of the commonly used types of milling cutters.
通常,铣刀可以被描述为具有旋转实体形状并将切削齿安装在周边或一到两个端面上的多刃切削刀具。下面是常用铣刀类型的快速综览。
Plain milling cutter. A plain milling cutter is a disk-shaped cutting tool that may have either straight or helical teeth, as shown in Fig.12.4a. This type is always mounted on horizontal milling machines and is used for machining flat surfaces.
平面铣刀,平面铣刀是一种盘状切削刀具.它可以具有直齿或螺旋齿.如图12.4a所示。这类铣刀总是安装在卧式铣床上.用于机加工平面。
Face milling cutter. A face milling cutter is also used for machining flat surfaces. It is bolted at the end of a short arbor, which is in turn mounted on a vertical milling machine. Fig.12.4b indicates a milling cutter of this type.
端面铣刀.端面铣刀也可用于机加工平面。它用螺栓固定在短刀杆的端部.而短刀杆则依次安装于立式铣床上。图12.4b显示了这类铣刀。
Plain metal slitting saw cutter. Fig.12.4c indicates a plain metal slitting saw cutter. we can see that it actually involves a very thin plain milling cutter.
平面金属开槽锯刃铣刀.图12.4c显示了一种平面金属开槽锯刃铣刀。可以看到它其实是一种很薄的平面铣刀。
Side milling cutter. A side milling cutter is used for cutting slots, grooves, and splines. As shown in Fig.12.4d, it is quite similar to the plain milling cutter, the difference being that this type has teeth on the sides. As is the case with the plain cutter, the cutting teeth can be straight or helical.
侧铣刀.侧铣刀用于切削狭槽、凹槽和花键槽。正如图12.4d所示.它与平面铣刀十分相似.差别在于此类铣刀齿在侧面。象平面铣刀的情况一样.切削齿既可以是直的也可以是螺旋的。
