Material: cast iron material or marble material.

 

Specification introduction of V-shaped frame: V-shaped iron is manufactured according to JB/T8047-95 standard, also called V-shaped frame. Commonly used are three-port V-shaped iron, single-port V-shaped iron and five-port V-shaped iron. V-shaped iron is made of HT200-250 material and supplied in pairs. It is mainly used for the detection, marking, positioning and clamping of shaft parts in machining.

              

V-shaped frame/cast V-block

 

Accuracy of V-frame: Divided into level 1, level 2, and level 3.

 

The V-shaped frame is mainly used to place round workpieces such as shafts, sleeves, discs, etc., in order to find the center line and draw the center line. Generally speaking, there are two V-shaped frames in one pair, and the flat surfaces and V-shaped grooves of the two pieces are ground in one installation.

 

The parallelism between the dimensions of the V-shaped frame and the surface, the perpendicularity error is within 0.01 mm, the center line of the V-shaped groove is in the symmetry plane of the V-shaped frame and is parallel to the bottom surface, and the concentricity and parallelism errors are also Within 0.01 mm, the half-angle error of the V-groove is within the range of ±30~±1.

 

The V-shaped frame can also be used for marking. The V-shaped frame with clamping bow frame can firmly clamp the cylindrical workpiece on the V-shaped frame and flip it to various positions for marking. The V-shaped frame is suitable for the detection, marking, positioning and other purposes of shaft parts.
