The PH Tool 90° Curved 5-Step Block is used for thickness and linearity calibration of curved surfaces. This 5-step block is machined from a solid 2” diameter bar with step thicknesses of .100”, .200”, .300”, .400” and .500”, with an ID radius of .50” and a step face of 1.000” x 90° arc. Metric version is also available.
Available in steel, stainless steel and special alloy. Custom designs also available.
Standard test blocks are non-representative tools, meaning that they are not manufactured from actual parts. Rather, they are a simplified design that contains manufactured discontinuities such as holes, angles, radii and more. Standard test blocks serve the purpose of standardizing and calibrating test equipment to ensure it is functioning properly.
All test blocks ship with a NIST-traceable certification report stating that the block meets applicable specifications.
