Measuring tool in R groove in ball slider

The utility model provides a measuring tool in R groove in ball slider, has the bonding base member of scale and bonds in the carbide stick of bonding base member both sides including the surface, andits tapering is 1: 250. The utility model discloses a both sides bonding carbide stick, with bonding substrate composition both sides for the arc surface has tapered seben to can be scaled on the surface, the tapering is 1: 250, every check width 1mm, every interval 1mm, 4 mu m's change takes place for the width size. The utility model discloses can carve surperficial groove width for 0.5mm's interval, but the groove is easy dazzled when more, consequently just carves and be the 1mm interval. So the precision of this measuring tool can reach 2 mu m, can estimate and read to 1 mu m. Consequently, the measuring precision of here measuring tool is fairly high, and cheap, processing, preparation convenience, and carbide is selected for use to the working face, and the wearability is high, andeasy big measuring is in
