V iron Type Frame classification: inspection V iron, crossed V iron, multi-port V iron, single ported V iron
V iron Type Frame use: for axial test, calibration, line, but also can be used to test the vertical degree, parallel degree. Precision shaft parts detection, line, or instrument and mechanical processing of the clamping.
V iron Type Frame manufacturing standard: according to national GB4972-85 standard manufacturing cast iron v type frame according to JB/T8047-95 standard manufacturing, using HT200 material, general paired supply.
V iron material classification:
Cast iron V iron material can be divided into two types of ductile iron and grey iron
V type frame of bearing requirements:
V type frame of bearing is refers to the V type frame unit area bear weight, V type frame deformation deflection. To facilitate the understanding, we can as V type frame put good workpiece, in does not affect the normal use, V type rack can withstand pressure.
V iron Type Frame according to mechanical industry standard JB/T8047-95 manufacturing, v iron material selects high quality HT200 gray. Vee blocks according to the material into the ball iron V type frame and grey iron V type rack, general ball iron V type frame use relative to the situation of the crucible material is less, the most used for grinding V type frame, etc.; The crucible V type frame is widely used, and the crucible V type rack V block with low cost, short production cycle, the craft is simple, durable, is the first choice of manufacturers and users.
