Bar simple bar with perforated plate 150x250 mm

The bar-sine principle allows the creation of angles with a tolerance of ± 4” of degree by positioning with plane-parallel blocks on both inclinations. Suitable for high-precision work on surface grinders or as a checking tool. Made entirely of alloy steels, non-deformable, hardened to a hardness of 58/60 HRC. The special clamping system ensures repeatability during machining. With the bar-sine, a table of values is supplied to be produced with plane-parallel blocks in order to obtain the required angle.
