Possibilities for minimizing uncertainty of dissimilar materials gauge blocks
calibration by mechanical comparison, Measurement, Vol.
National standard for length in Slovenia comprise of 122-piece set of steel gauge blocks
, ranging from 0,5 mm to 125 mm and some additional steel gauge blocks
of length up to 1000 mm.
Maintaining parallelism between the two end faces of gauge blocks
requires particular mounting conditions.
This extra control, coupled with improved operational procedures, has allowed a faster throughput of gauge blocks
and reduced NPL's measurement uncertainty claim to better than half for longer gauge blocks
Broomfield's tungsten carbide gauge blocks
are used by manufacturers - including aerospace engineers, glassmakers and the oil industry - who need to make precision measurements.
For dimensional metrology, management's ultimate tool for technologically ensuring precision, and the product reliability depending on this precision, is the use of gauge blocks
, including the all-important master set of some 81 individual blocks.
Place gauge on block on the table directly under the infeed roll and move the table up until light contact is made between roll and gauge blocks
. Move gauge block
across full width of table and check clearance on left end.
Non-steel materials of gauge blocks
are increasingly gaining its popularity, among them especially oxygen ceramics with its mechanical properties being close to the steel.
While gauge blocks
are not quite dead yet, they are also not quite alive.
The company, which supplies metal gauge blocks
for the manufacturing industry, has moved from Broomfield House at Firth Street, Huddersfield.
For example, consider a hand held micrometer that is calibrated for measuring work-pieces with flat and parallel surfaces by measuring several calibrated gauge blocks
(with surfaces larger than the micrometer anvil size).
