Double bar with drilled plate 150x250 mm

The bar-sine principle allows the creation of angles with tolerance ± 4" of degree by using positioning with plane-parallel blocks on both inclinations. Suitable for high-precision work on grinding machines or as a measuring/control tool. Completely made of alloy steels, non-deformable, hardened to 58/60 HRC. The special clamping system ensures repeatability during machining. With the sine bar, the value table is supplied to be produced with plane-parallel blocks in order to obtain the required angle.
