 Material: cast iron or marble material 
 V-shaped rack Specifications: 
 1, V-shaped iron manufactured by JB/T8047-95 standard, also known as V-shaped frame, there are three V-shaped iron, single-port V-shaped iron, and five V-shaped iron. V-shaped iron quality HT200-250 material, pairs of supply is mainly used in the detection precision shaft parts, crossed the given instrument and machining fixture. 
 , V-frame accuracy: divided into 1, 2, 3. 
 Third, the V-frame is mainly used to round workpieces placed shaft, sleeve, disc, in order to find the centerline and draw the centerline. V-shaped frame are a two, two of the plane and V-groove in a single installation grind. Precision V-shaped frame size each other between the surface of parallelism, perpendicularity error of 0.01 mm, the V-shaped groove of the centerline necessary for the error in the symmetry plane of the V-shaped frame and the bottom parallel, concentricity, parallelism within 0.01 mm V-groove half-angle error is within ± 30 to ± 1 range. Precision V-shaped frame also can be crossed with clamping bow frame V-shaped frame can be a solid cylindrical workpiece clamping to various locations in the V-shaped rack, flip crossed. 
 V-shaped standard: manufactured according to the national GB4972-85 standard, generally in pairs supply, is a rectangular body, the work surface with a 90-degree V-groove. Mainly applied to the inspection and marking of small-scale shaft parts. 
 V-shaped frame uses: for shaft inspection, correction, dash, can also be used to test the workpiece perpendicular to the degree of parallelism.
