角钢的制造工艺比较简单，一般大型钢铁公司不会选择生产角钢，生产工艺可分为热轧和冷弯两种，热轧用于大尺寸角钢，

冷弯一般是比较小的。标准工艺是用钢坯（如方坯）经过专用的型钢轧机多道反复轧制逐渐轧成∨形状，材质有保证，

在角的内侧有过渡圆弧，机械性能可靠；而小作坊生产的则是用板材或带钢直接轧（弯）成的，角的内侧没有过渡圆弧，

而且由于是弯曲成的在角处的内应力较大，机械性能较差。角铁是用铸铁制成的车床附件，通常有两个互相垂直的工作表面。

在角铁上有长短不同的通孔，用以连接螺钉的通过。由于工件形状、大小不同，角铁除有内、外角铁之分外，还可做成不同形状，

以适应不同的加工要求。应具有一定的刚性和强度，以减少装夹变形。为此，除了在结构上增加一些肋、肋板外，

还应在铸造后进行时效处理。角铁的工作表面和定位基准必须经过磨削或精刮研以确保接触性能好、角度准确。

通常角铁与花盘一起配合使用。

The manufacturing process of Angle steel is relatively simple, generally large steel companies will not choose to produce Angle steel,

the production process can be divided into hot rolling and cold bending, hot rolling is used for large size Angle steel,

cold bending is generally relatively small.The standard process is to use billet (such as billet) through special repeated rolling gradually rolling shape,

material guarantee, transition arc in the corners, reliable mechanical performance;

and small workshop production is made with plate or strip directly rolling (bending), the corners inside no transition arc,

and because of the bending in the corners, poor mechanical performance.Corned iron is a lathe accessory made of cast iron,

usually with two working surfaces perpendicular to each other.

There are through holes of different lengths in the corner iron to connect the passage of the screws.

Due to the different shape and size of the workpiece,

corner iron can also the inner and outer corner iron into different shapes to meet different processing requirements.

Provide rigidity and strength to reduce clamp deformation.For this reason, in addition to adding some ribs and ribs to the structure,

it should also be treated timely after casting.

The working surface and positioning reference of corner iron must be ground or scraped to ensure good contact performance and accurate Angle.

Usually corner iron is used with flower discs.
