[0002] Due to the particularity of cemented carbide pressing, complex-shaped cemented carbide blanks cannot be formed directly, so most of them use semi-additive methods to obtain relatively complex-shaped finished materials. The density and strength of cemented carbide pressed blanks are relatively low. If they are directly clamped on a three-jaw chuck of a lathe, they are prone to problems such as clamping, clamping marks, and clamping cracks, which do not meet quality requirements. Other fixtures, such as steel parts, have low elasticity and are prone to damage if the clamping force is not properly controlled. In addition, the production cost and material cost are relatively high.
[0003] According to a 3D printing fixture disclosed (publication number: CN 211194942 The cam is provided with a plurality of support plates, the support plates being equidistant from the outside of the cam and the support plates being slidably connected to the support plates. Utility Model Content
