Machining technology of machine tool gearbox parts and design of special machine tool fixture

Let me put it simply, I did it. The box has the characteristics of thin wall thickness, easy deformation and difficult control of hole position tolerance. Generally, it needs to be machined on a boring machine. When clamping, be careful not to be caught in the weak point of the box, so as not to crush or deform the box. Firstly, the bottom surface of the box is used as the datum plane for processing, and then the hole system is processed based on the datum plane.
