How many materials are used for the V-frame

The V-shaped iron frame is manufactured according to the GB4972-85 standard and is usually supplied in pairs. It is a four sided prism with four 90 degree grooves on different working surfaces or four different sizes. Mainly suitable for inspection and marking of shaft parts. V-frame specifications: 100× 80× 30mm150× 125× 45mm The V-shaped frame is mainly used to place circular workpieces such as shafts, sleeves, and discs, in order to find and draw the centerline. A regular V-frame consists of one pair of two pieces, and the planes and V-grooves of the two pieces are ground in one device. The parallelism and perpendicularity error between the dimensions of the V-shaped frame and the outer surface are within 0.01 millimeters. The centerline of the V-shaped groove is in the symmetrical plane of the V-shaped frame and parallel to the bottom surface. The concentricity and parallelism error are also within 0.01 millimeters. The half angle error of the V-shaped groove is within± 30~± Within 1 range. The V-shaped frame can also be used for marking. The V-shaped frame with a clamping bow can firmly clamp cylindrical workpieces onto the V-shaped frame and flip them to various positions for marking. Our company mainly consumes measuring tools such as cast iron flat plates, rulers, square boxes, and cylinders
