大量块，一般是指名义尺寸30mm至1000mm的基块。由于量块的中心长度大，放在研磨中所用的正压力也大。量块的尺寸越大，在推动中克服量块倾斜的平衡压力也将随着增加，否则就不会平衡。在研磨中，为了减少量块的晃动，平板应放置水平，使量块的重心通过量块的几何中心线。另外 A large number of blocks, generally refers to the nominal size of 30mm to 1000mm base block. Because of the large center of the block, the positive pressure on the mill is also large. The larger the size of the gauge block, the more the equilibrium pressure overcoming the inclination of the gauge block will increase as you push otherwise unbalancing. In grinding, in order to reduce the shaking of the measuring block, the flat plate should be placed horizontally so that the center of gravity of the measuring block can pass through the geometric center line of the measuring block.
