Cast iron V- block can be used for precision shaft parts of the detection, marking, positioning and machining of the clamping, general supply in pairs, is a quadrilateral body, four working surfaces or four different sizes of 90 degrees of the slot, mainly for the shaft parts of the inspection and crossed.
Cast iron V- block can be divided into ductile iron V-shaped frame and gray iron V-iron according to the material, ductile iron V-type use is relatively small, generally use smaller specifications, high precision V-type iron, such as: grinding V-iron. Ductile iron V-type frame accuracy is greater than 0 level. Gray iron V-type frame is used widely, low cost, short production cycle, simple process, it is durable, is one of the preferred reasons for manufacturers and users.
