With a Snap Gage 83% (20,8 ìm/.0008“)...

6 - • Statistical Process Control • Setting up and/or adjusting a processing machine • Well timed tool change, for example the replacement of a grinding wheel. • No numerical value or measurement is obtained, therefore the manufacturing process cannot be steered appropriately. • Changes to manufacturing processes cannot be identified in time. • With the constant measuring force eliminates the influence of the worker upon the measuring results. • The influence of the worker on a test / inspection results can be substantially affected through incorrect handling (bending upwards). No Go Go The Measuring...

7 + • Minimum wear due to non-contact positioning of the work piece with the retracting sensitive anvil • Reduced wear due to the carbide tipped measuring faces • High abrasion of the measuring faces due to the actual physical strain upon the measuring faces • Can be quickly adjusted within the dimension and fit of the measuring range • Additional costs are reduced (administration of measuring equipment, calibration) • Requires more storage, money is tied up in having a broader selection of snap gages • Additional costs are thus higher (administration of measuring equipment, calibration, storage)....
