With this base the 3D coordinates of already existing bore holes of tools, fixtures, etc. can be determined. For this purpose, the base is equipped with a concentric stud.
The bolt diameters are manufactured with "h6 accuracy“. The ball center is located exactly in the stud axis (=bore axis).
The 3490-020 Ball Prism Base For Measuring Bore Holes features:
Features:
• Base made of stainless steel (V2A)
• Integrated permanent magnet
• Compatible with ball prisms: 1.5″ (38,1 mm)
• Positional accuracy of the ball in the base: ± 0,02 mm
• Height-Offset HO of prism center: 25 ± 0,1 mm
• The small distance to the object allows very accurate measurements
• Ring marking with engraved ball diameter 1.5″ (38,1 mm) and Height-Offset HO 25 mm
Thanks to the small distance of only 25 mm it is possible to get very accurate measurements.
Available LxD:
• 6x8mm / 8x10mm / 10x12mm / 12x14mm
