Granite squares
|
Granite squares are primarily used for dimensional accuracy and calibration in situations where both surface flatness and angular accuracy are critical. Typical applications:

- Measurement and inspection laboratories * Used as a reference tool when calibrating or checking other measuring instruments (e.g. machining tables, height measuring instruments) * The stability of the granite and the low thermal expansion ensure that angles remain accurate over long periods of use - Machine shops and production lines * Checking workpiece position and angles before and after machining * Serves as a reference surface for positioning workpieces in precision fixtures. - Quality assurance and documentation * Used as proof that the dimensions and angles of products meet the requirements of standards. * Particularly important in demanding industries such as aerospace, defence, and medical equipment. - Workstation calibration * Ensuring that measuring tables, precision jigs, and other precision equipment are in the correct position and angle. Why granite? * Highly rigid and wear resistant - retains its shape for decades. * Low coefficient of thermal expansion - does not distort as much as metal with temperature changes. * Non-magnetising - does not affect magnetic measuring instruments or metal shavings. * Corrosion free - will not rust in damp conditions. |
