Example Embodiment
[0024] The technical solutions of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0025] see figure 1 , the present embodiment is a method of processing a diamond engineering thin-walled drill base. First, determine the components of the diamond engineering thin-walled drill base, which is composed of three parts: a steel pipe body 1, a joint piece 2 and a joint 3, wherein the steel pipe body 1 The raw material is obtained by cold gadolinium method, the outer diameter of the joint piece 2 and the outer diameter of the steel pipe body 1 are machined and polished to the same size after welding, and the shape of the joint 3 is a hexagonal nut shape.
[0026] There is a boss 21 at the connection part between the joint piece 2 and the steel pipe body 1, such as figure 2 As shown, the outer diameter of the boss 21 is a clearance fit with the inner diameter of the steel pipe body 1 . 8 tooth r...
