Contract awarded for 1) 30xxn030-wheel diameter measuring gauge fitted with vernier scale of range 800 to 1000 mm ,accuracy 0.10 mm,along with standard length test bar and calibration certificate from nabl/govt approved test house .;
Different methods have been used to measure tooth dimensions, many authors employed sliding caliper with a Vernier scale to obtain the metrical data of the teeth, due to its accuracy over other methods.16 The use of digital Vernier calipers can virtually eliminate measurement transfer and calculation errors when compared with divider and calculator.
This lets users make incremental adjustments for critical diameter tolerances without using a Vernier scale. The EWB UP series' six boring heads bore from 0.787" to 3.94" with a range of spindle interface options.
