Thread milling
The research work on thread milling mainly focuses on both theoretical and technological aspects. Thread milling generally involves multiple cutting operations, including rough machining and precision machining. However, for difficult to machine materials, the cutting force during milling is sign...Read More -
Basic knowledge of common thread
thread identification ① Discrimination of thread typeGenerally, first observe its tooth type, the tooth type of ordinary thread is generally triangular, the top and bottom of the tooth have a small plane, the tooth Angle is 600; 550 non-sealed pipe thread is a ...Read More -
Bolt anti loosening form and precautions
As a commonly used tool in fixtures, bolts are widely used, but long-term use can also bring many problems, such as loose connections, insufficient clamping force, and rusting of bolts. During the processing and production of parts, the looseness of bolt connections can affect t...Read More -
Thread bottom hole and tapping depth
I. IntroductionIn fact, in the design process, especially the designers with several years of work experience, under normal circumstances, basically will not consult the manual to determine, such as M10 screws, how big the bottom hole I want to play, how much is the depth, how much tol...Read More -
Principle of Bolt Connection and Tightening
5, bolt removal common problems When loosening the flange bolts of pipes and valves: Should be loosened away from the body half of the bolt, so that the remaining oil, steam, water from the opposite discharge, in case of spray, scalding If the bolt has glue that cannot be u...Read More -

Thread surface roughness
The surface roughness requirements for threads are 3.2 for qualified products and 1.6 for first class and excellent products. The accuracy of labeling on threads, such as M8X1-6h, requires a relatively high surface roughness. The requirements for con...Read More -
How to determine if the bolts are tightened Torque measurement technology
1.Why do we need to perform static torque testing? In many cases, the torque value during the production process and the torque value detected during offline testing are different. For example, the torque displayed on the controller is 100Nm, and the torque value dete...Read More -
Thread-turning process
Thread turning is a very common and complicated problem in machining. The requirements of thread turning are higher than other ordinary turning operations, and the cutting force generated during turning is generally large.When turning thread, due to the influence of thread ri...Read More
