Marble V-shaped frame

The marble V-shaped frame is suitable for the detection,marking,positioning and other purposes of shaft components.

The marble V-shaped frame is mainly used to place circular workpieces such as shafts,sleeves,and discs,in order to find and draw the centerline.Generally,a V-frame consists of one pair of two pieces,and the planes and V-grooves of the two pieces are ground out in one installation.The parallelism and perpendicularity error between the surfaces of the V-shaped frame are within 0.01 millimeters.The centerline of the V-shaped groove is within the symmetry plane of the V-shaped frame and parallel to the bottom surface.The concentricity and parallelism error are also within 0.01 millimeters.The half angle error of the V-shaped groove is within the range of±30~±1.The V-shaped frame can also be used for marking.The V-shaped frame with a clamping bow can firmly clamp cylindrical workpieces onto the V-shaped frame and flip them to various positions for marking.

The marble V-shaped frame is made of Jinan green marble,which has been mechanically processed and finely ground by hand.Black luster,uniform structure and texture,good stability,high strength,this product also has advantages such as:no rust,no magnetization,no change in shape,good quality,etc.Can maintain stability under heavy loads and general temperatures.

Features of Marble V-shaped Frame:

1.It is a benchmark measurement tool made of stone materials,which is an ideal reference plane for the inspection of instruments,tools,and mechanical components,especially for measurement purposes.

2.The marble V-shaped frame is made from underground rock layers and has undergone natural aging for billions of years.Its shape is extremely stable and there is no need to worry about deformation due to conventional temperature differences.The marble material,which has undergone strict physical testing and selection,is finely crystallized and has a hard texture.

3.Due to the non-metallic nature of marble,it exhibits magnetic reactions and no plastic deformation.Therefore,the accuracy retention is good.Even if the marble V-shaped frame is hit by heavy objects during use,at most a few pieces of stone debris will fall off.This product is a measurement reference component made of cast iron and steel,which can achieve high and stable accuracy.
