Shanghai Machine Tool Plant successfully developed high-precision CNC grinding machine

Shanghai Machine Tool Works Co., Ltd. recently developed two high-precision CNC grinding machines, one for the SK7520/H CNC universal thread grinder and the other for the MK8332Ñ…1250mm CNC camshaft grinder.



Among them, SK7520/H universal universal thread grinding machine is widely used for processing thread of precision screw, plug gauge, inner and outer cylinder and taper thread workpiece. It can also grind worm and various shapes of thread, such as triangular thread and trapezoidal thread. , ball screw, etc., can complete the helical gear of various profiles. The machine adopts many high-tech and unique artificial granite beds, which makes the machine have higher shock resistance, rigidity and thermal stability. The wheel seat adopts cylindrical structure, good rigidity and wide adjustment range of spiral angle. It can also be used for large-scale screw grinding.

This flange is circumferentially welded into the systemat its neck which means that the integrity of the buttwelded area can be easily examined by radiography. The bores of both pipe and flange match, which Reduces turbulence and erosion inside the pipeline. The weld neck is therefore favoured in critical applications
