V frame apply to accurate axis kind of component detect, underline, the utility such as fixed position. It is platform measures medium important and auxiliary tool. Material qualitative: ? is troubled by sail Ge uses up Xing is troubled by the magpie that show to light? cent to be high accuracy, common precision two kinds. V frame basically use put an axis, sleeve, the circular workpiece such as disc, so that seek central line and clue of lay off center. General V wearing is a pair two, two plane and V chamfer is grind in be made make or blow what grind and become. Accurate V worn size the parallelism between mutual surface, verticality error is in 0. In 01 millimeter, the central line of V chamfer is indispensible as parallel as underside inside V worn symmetrical plane, homocentric degree, the error of parallelism also is in 0. In 01 millimeter, half horn error is in V chamfer inside 1 limits of ± 30~ ± . Accurate V frame also can make square box use, the V that contains clip to hold a tool frame, can cylindrical the clip with firm workpiece is held in V model frame on, retroflexion each positions are underlined.
