The thread specification of the oil outlet of the oil drum should be judged according to many aspects, and there are also many stresses. First of all, there should be a multi-angle template for the lathe operator to use. The cutter should be aligned with the required angle. When grinding, the two cutting edges should be straight, and the angle should be subject to the pitch. Large pitch and large helix angle. Therefore, it is necessary to pay attention to many aspects whether the size of the oil drum oil outlet thread specification is appropriate.
For example, the thread of the small hole on the oil drum cover is generally less than 60 degrees, because the angle of the thread refers to the axial tooth angle. For right-handed threads, in order to improve the cutting performance of right-handed blades, the front part of the tool is always used. Therefore, the thread size of each oil drum is very different, even very different. If you need to choose the thread size of the oil drum, remember to find out the information clearly.
