Fig. 402. Check of a head of the block of cylinders on deformation by means of a measuring ruler and щупа

Surface of the block of cylinders check on deformation by the way similar to check of a head of the block of cylinders (see fig. 402 ). Measure the block of cylinders in the longitudinal, cross-section direction and on a diagonal. Thus should not enter щуп in the thickness more than 0,1 mm.
