SQUARE-line

The SA-50 air injector unit included in delivery generates the necessary vacuum. It is easily connected by standard adaptor to the compressed air supply. The suction force, and hence the SQUARE-line gliding characteristics, are controlled precisely by a throttle valve on the SA-50 air unit.

Various measuring sensors can be mounted in the 8 mm standard borings. The width of the hard stone reference angle and any parallelism errors are compensated by a sprung side-plate. The guideway surfaces are specially finished by a highly sophisticated process to ensure optimal sliding characteristics and wear resistance.

 

Advantages:

  • The SQUARE-line measuring saddle and hard stone reference angle comprise a universal instrument for all squareness measurements
  • The user-friendliness and high precision of this instrument are unaffected by workshop conditions
  • With optional accessories, high-precision parallelism measurements can also be carried out with the greatest ease
  • The SQUARE-line measuring saddle is a cost-effective and useful extension for existing equipment

Calibration Set for Knife-Edge Squares

Kunz precision presents a simple but unique solution for measuring knife-edge squares: Hereby the new developed lever gauge GT 31-TK is employed. The measuring probe shows a cylindrical touching surface with two markings in between which the test piece is being probed. In this way, the inner and outer leg of the test piece can be measured quickly and straightforward.
