During the production and processing of cold-rolled steel, the refrigeration lubricant can reduce the drilling heat and cutting speed in the process of drilling system. In this way, it can not only increase the service life of NC blade, but also ensure the smoothness of cold-rolled steel production and processing. In the future, we should pay attention to the use of emulsified oil, but for substances with high requirements for smoothness, we should use stainless steel special cutting fluid.

During the production and processing of cold rolled steel, for this hole, we should pay attention to the use of the full grinding drill, and consider the freezing liquid. For 316 or 303 tapping teeth, it is OK to use the work thread tapping. If it is 304 of the national standard, Fuji brand must be used at the moment. In addition, for others such as 301202, yamava must be used.

During the production and processing of cold rolled steel, pay attention to take away 15 ° ~ 20 ° from the front corner of NC blade. After that, the heat treatment for stainless steel drilling will look more suitable. When carrying out preliminary processing, be sure to add smaller rear corners first; At the time of deep processing, the back angle of about 6 ° ~ 8 ° is more suitable because it simply shows the hard bottom phenomenon of the process of material production and processing system.

In general, it should be noted that this corner will be larger than that in the production and processing of general carbon steel. And because of this, people should pay attention to the inclination angle of this blade. Generally, they should pay attention to taking away 15 ° as the best. If it is the time of finishing turning the round, boring and planing plan outside the window, when the amount of knife is less, we should pay attention to using the NC blade with large blade inclination angle of 50 ° up and down.

Finally, when cold rolling steel is carrying out hard production and processing, it will produce more heat, which will greatly damage the NC blade. In the future, it will certainly give many people a headache. Naturally, now symptomatic treatment, all the better and easier. For tungsten cobalt aluminum alloy, it has excellent patience, light and agile drilling, and it is not easy to stick the knife. It is especially suitable for initial processing with great vibration and cold-rolled steel milling with intermittent drilling.
