CNC machining of general curved parts usually uses ball end mills. When the ball end milling cutter is used to machine the curved surface, the cutting process is performed by the line cutting method, that is, the milling cutter processes the curved surface line by line along the coordinate axis...

The tool path is completely customized according to the special requirements of the stator track. Moreover, through coordinate transformation, three-axis CNC milling is used to process complex lateral concave surfaces. The stator track NC programming requirements are met, which is unmatched by the...

The guide sleeve is an important part in the hydraulic support of the coal mining machinery industry. The hydraulic cylinder piston and the guide sleeve are a pair of friction pairs. If the dimensional accuracy is not high, the piston will cause friction due to friction and wear during long-term...

methyl methacrylate (PMMa) is commonly known as plexiglass. Today, we will carefully understand the main points of PMMA's injection molding process. Due to the short surface hardness of PMMA, easy to rub, low impact resistance and poor molding flow performance, PMMA modification has appeared one...
