铸铁V型架用于精密轴类零件的检测、划线、定位及机械加工中的装夹，一般都成对供应，是一个四棱体，四个工作面上或四个尺寸不同的90度的槽,主要用于轴类零件的检验和划线。

铸铁V型架按材质可以分为球铁V型架和灰铁V架铁两类：球铁V型架的使用比较少，一般使用规格较小，精度要求较高的V型铁，比如：研磨V型铁。球铁V型架的精度大于0级。灰铁V型架的使用比较广泛，灰铁的成本低、生产周期短，工艺简单、经久耐用是制造商和用户的首选原因之一。

铸铁V型架按国家GB4972-85标准制造，V型架规格：100×80×30mm 150×125×45mm

Cast iron V-frames are used for the inspection, scribing, positioning and machining of precision shaft parts. They are usually supplied in pairs. They are a quadrangular body, four working faces or four different 90 degrees. The slot is mainly used for inspection and scribing of shaft parts.

Cast iron V-frame can be divided into two types: ductile iron V-frame and gray iron V-frame iron. The use of ductile iron V-frame is relatively small. Generally, V-shaped iron with smaller specifications and higher precision is used, such as: Grinding the V-shaped iron. The accuracy of the ductile iron V-frame is greater than 0. Gray iron V-frames are widely used. The low cost of gray iron, short production cycle, simple process and durability are one of the preferred reasons for manufacturers and users.

Cast iron V-frame is manufactured according to national GB4972-85 standard. V-frame specification: 100×80×30mm 150×125×45mm
