Difference Analysis Of Cylindrical Saw Blade Milling Cutter And End Milling Cutter

Saw blade milling cutter is a kind of rotary cutter used in milling. Cylindrical saw blade milling cutter is a kind of common saw blade milling cutter. In practical production, it will be classified according to the tooth shape. There are mainly two types: straight tooth and spiral tooth. According to the number of teeth, it is divided into coarse tooth and fine tooth. Spiral tooth coarse tooth saw blade milling cutter has the characteristics of few teeth, high tooth strength and large chip space, which is commonly used in rough machining; Fine tooth saw blade milling cutter is more suitable for finishing. In practical production, cylindrical saw blade milling cutter and end milling cutter are commonly used. Let's introduce the differences between the two kinds of cutters.

When cylindrical saw blade milling cutter is milling, the saw blade milling cutter rotates continuously, so the productivity is high and the milling speed is high. In continuous cutting and milling, every cutter tooth is cutting continuously, especially in end milling. The milling force fluctuates greatly, so the vibration can not be prevented. Oscillation will be more severe when the oscillation frequency is the same as or multiple of the natural frequency of the machine tool. Multi Tool and multi edge cutting saw blade milling cutter has many teeth, and the total length of cutting edge is large. It is very helpful to improve the durability and productivity of cutting tool, and has many advantages.

However, there are also the following problems: first, the cutter teeth simply have radial runout, which will result in unequal load and uneven wear of cutter teeth, affecting the machined surface quality. Second, the chip space of the cutter teeth must be enough to prevent damage to the cutter teeth. In order to improve the tool life and productivity, different milling methods can be selected according to different processing conditions, such as reverse milling, forward milling, symmetric milling, asymmetric milling, etc.

The end mill is also a kind of tool commonly used in machining. The direct difference between it and the cylindrical saw blade milling cutter is that the cylindrical saw blade milling cutter needs to be used on the cutter rod, and the end milling cutter can be used when it is directly inserted into the taper hole of the spindle. End milling cutter is mainly used for machining groove and step surface. In the process of machining, high speed steel end mill is widely used and required, and there will not be too much error when the cutting conditions are not good. Although cemented carbide end mill has good wear resistance in high speed cutting, it is not widely used as high speed steel end mill.

In the practice of machining production, should choose cylindrical saw blade milling cutter or end milling cutter, according to the processing material and processing quantity to choose. The correct selection of cutting tools will help to save processing time and improve processing efficiency.
