Granite Measuring Instruments

Due to its unique features, black granite has been used extensively in the fields of measuring instruments. Granite has a low temperature expansion coefficient, which is much lower than the one of metal. In addition, granite is a good electrical isolator, insensitive to scratches and resistant to corrosion, thus making it ideal for measurement products on the workshop floor. In addition to using granite for its machines, ZSM provides a wide range of granite measuring instruments which adhere to the German DIN 875/876 standards.

All granite components, be it for our measuring machines or for the measuring instruments listed below, are produced in-house, with a highly skilled and dedicated team with years of experience and high quality standards.

Surface Plates
  • Suitable for use in workshop and metrological environments

  • Can be supplied with holes, glued inserts, T-slots, clearing grooves, dovetail and fitting rubber feet for small sizes.

H-type Parallels
  • H-shape profile to ensure stability and lightness

  • Two lapped parallel surfaces, suited for testing straightness and parallelism

  • If required, handles on the heads can be supplied

Paired Parallels
  • Supplied as two matching pieces

  • High precision parallelism of surfaces and perpendicularity to sides

  • Suitable for testing parallelism of parts and precisely jacking up parts

Linear Rulers
  • The top working surface is perfect for high precision testing of linearity and for comparing guides or lapped surfaces

  • If needed, linear rulers can be equipped with handles on the heads

Angles
  • With reduction holes for better handling and weight reduction

  • Suitable for testing perpendicularity

Squares
  • With reduction holes for better handling and weight reduction

  • Suitable for testing perpendicularity and parallelism

  • The four outer surfaces are paired parallel to each other and at right angles to one another

Rectangular Rulers
  • With reduction holes for better handling and weight reduction

  • Suitable for testing perpendicularity and parallelism

  • The four outer surfaces are in pairs parallel or perpendicular to each other

Cubes
  • Suitable for component inspection and use in quality inspection, calibration, and assembling environments

  • Available in two versions, each with 4 or 6 working surfaces, each parallel or at right angles to one another
