Precision Sine Tables manufactured using high grade stress relieved cast iron with hardened steel hinge and setting rollers.
The Precision Sine Tables have an angular accuracy on 9 arc seconds and have a top plate ground flat to within 0.005mm.
The Precision Sine Tables from Exact Metrology are precise for inspection, yet rugged enough for machining operations. The Precision Sine Tables are fitted with side end rails.
Imperial equivalent sizes are also available.
The underside of the base plate is hand scraped to achieve optimum flatness while the top, side and end faces are all ground flat, parallel and square to within 0.005mm.
