V-frame

V-shaped iron is manufactured according to JB/T8047-95 standard, also known as V-frame. Commonly used are three V-shaped irons, single-port V-shaped iron and five-port V-shaped iron. The V-shaped iron is made of HT200-250 and is supplied in pairs. It is mainly used for the inspection, scribing, calibration and machining of precision shaft parts.

Product description

V-shaped iron is manufactured according to JB/T8047-95 standard, also known as V-frame. Commonly used are three V-shaped irons, single-port V-shaped iron and five-port V-shaped iron. The V-shaped iron is made of HT200-250 and is supplied in pairs. It is mainly used for the inspection, scribing, calibration and machining of precision shaft parts.

The V-shaped frame is mainly used to place circular workpieces such as shafts, sleeves and discs in order to find the center line and draw the center line. Generally, the V-frames are a pair of two pieces, and the two planes and the V-shaped grooves are all ground in one installation. The precision of the V-frame is parallel to each other. The verticality error is within 0.01 mm. The center line of the V-groove must be in the symmetry plane of the V-frame and parallel to the bottom surface. Concentricity and parallelism errors are also Within 0.01 mm, the V-groove half-angle error is within the range of ±30~±1. The precision V-frame can also be scribed, with a V-frame that holds the yoke, which can hold the cylindrical workpiece firmly on the V-frame and flip it to each position.

V-frame accuracy: divided into 1, 2, and 3.
