Diatest - Setting Rings

Standard Size Setting Rings, sized in the middle of a probe's range for setting gauges to zero

• It is recommended to zero-set a split-ball probe with a setting master. This is the fastest and safest method since the test object(bore) and the setting means are equal in shape.
• DIATEST-Setting rings are produced in metric and in inch style without deviation engraved since this may easily lead to setting error sbecause of mistaking of plus- and minus-deviations.
• Design of the DIATEST-Setting rings Nominal sizes 0.500 -1.500 (0.0200“- 0.0600“)
• Ring mounting made of steel, black finished. Insert made of synthetic sapphire.
• Bore finely Lapped. Nominal sizes 1.750 - 40.000 (0.0625“-1.5800“) Made of wear resisting special steel, black finished.
• Bore finely lapped.  Rings are artificially aged and thus particularly permanent to size.
• Max. deviation from mean diameter : 0.001mm (.000040")
• Max. deviation in roundness : 0.0003mm (.000012")
• Max deviation in straightness and parallelism over ZL : 0.0005mm (.000020")
• Surface roughness : CLA 0.00002mm (0.8 micron)
• Hardness : 62-64 Rockwell C
