Tape Measure,Metal Tape Measure,Measuring Tape,Gauging Tape Henan Liangjin Tools Co.,Ltd , https://www.jtapemeasure.com The M131W grinding machine used in our factory is the product of Shanghai Machine Tool Plant in the early 70s. It has the following disadvantages: (1) The spindle assembly reference piece is a three-watt dynamic pressure sliding bearing. The single-piece movable tile is swung on the spherical support to form a converging lubricating oil wedge, and the rotating and viscous body of the main shaft forms an oil bearing film. However, due to the poor contact stiffness of the spherical support, the support area of ​​the three-watt is small, and the bearing capacity of the main shaft is limited.
