Gauge block Measuring surface and can measure surface lapping block and the other amount used in combination, and can also have a similar surface quality of auxiliary Surface lapping surface and is used to measure the amount of the block length. 3.2 Block length l lengthofagaugeblockl Block an arbitrary point surface measurements to measure its opposite vertical auxiliary body surface lapping surface between Straight away. Material and surface quality of auxiliary bodies should be the same as the amount of the block shown in Figure 1. Note. 1 Block from the measure does not include any point to point 0.8mm surface edge region. 2 Block length including single-sided lapping of. 3 Block length l is the length and value of the physical configuration of the unit. 3.3 Block central length lc centrallengthofagaugeblocklc Amount corresponding block is not the center of the measuring surface lapping amount of block length (Figure 1). 3.4 Block nominal length ln nominallengthofagaugeblockln Marked on the Block, to indicate its magnitude relationship between the main unit (m) and is also known as the amount of block length Indication. 3.5 Block length deviation e deviationofthelengthatanypointfromnominallengthe Algebraic difference between the amount of block length and nominal length at any point, that e = l-ln.
