What do saw blade cutters need to pay attention to in daily milling?

The saw blade milling cutter rotates continuously during milling, so the productivity is high and high milling speed is allowed. During continuous cutting and milling, each tooth is continuously cutting, and the milling force fluctuates greatly, so vibration is inevitable. Vibration can be severe when the frequency of vibration is the same as or a multiple of the natural frequency of the machine tool. The saw blade milling cutter has many teeth and the total length of the cutting edge is large, which is of great help to improve the durability and productivity of the tool, and has many advantages.

The saw blade milling cutter is also a commonly used tool in processing. The direct difference between it and the cylindrical milling cutter is that the cylindrical milling cutter needs to be worn on the arbor, and the saw blade milling cutter can be used directly inserted into the taper hole of the spindle. Saw blade milling cutters are mainly used for machining grooves and stepped surfaces. In processing, the use range and use requirements of high-speed steel saw blade milling cutters are relatively wide, and there will not be too much error in the case of poor cutting conditions. Although the carbide saw blade milling cutter has good wear resistance during high-speed cutting, its application range is not as extensive as that of the high-speed steel saw blade milling cutter.

In the actual machining production, the saw blade milling cutter should be selected, which needs to be selected according to the material and processing volume to be processed. The correct choice of tools will greatly help to save processing time and improve processing efficiency.

Daily operation specifications of saw blade milling cutter:

1. After the high-speed steel saw blade milling cutter is just installed, it should be tested first to ensure that the new saw blade and the equipment have a good coordination, which will promote the cutting quality and service life of the saw blade and the equipment. Please be sure to slow down the feeding speed of the saw blade before the actual cutting process, otherwise it will easily cause damage to the saw blade if you start normal sawing.

2. It is very necessary to adjust and reduce the feed for special materials, such as stainless steel and other materials that are difficult to cut and have high toughness, the feed should be reduced; this will help prolong the service life of the high-speed steel saw blade, and also The cross section of the material is related. For the smaller diameter, it can be adjusted according to the actual situation.

3. If the feed speed of the same material is increased when cutting, be sure to choose coarse teeth; the saw blade is a consumable item, and the cutting angle and pitch are very important. If necessary, it needs to be ground to maximize the saw blade. benefit. For specific circumstances, please refer to "How to judge whether a carbide saw blade needs to be ground"

4. In the daily work of the saw blade milling cutter, be sure to observe the iron filings produced by the high-speed steel saw blade during sawing, and you can judge some states of the saw blade: if the sawing sawdust is relatively small or very thin, when the If it is powdery, it can be judged that the current cutting pressure is too small and should be adjusted in time.
