Abstract
In the actual processing, the workstages of spot facingmachining are drilling, reaming, rounding chamfer and so on in milling machine. In large batch production, the workstages are disperse, using more equipments and tools with low working efficiency and high processing cost. And it is difficult to ensure the accuracy of the hole. For these disadvantages, this paper designs a compound tool of spot facingmachining which subjects the drill, reamer and chamfer mill. It can complete three workstages in one setup. And this paper designs the structure of the cutting tool, chooses the material of the cutting part, sets the parameters of cutting part and gives the reference value of cutting parameters. This cutting tool compounds the structure of drill, reamer and chamfer mill, so the manufacturing process is more complex. And this paper also introduces the manufacturing process of the cutting tool in detail. It is rather difficult in designing and manufacturing this spot facingmachining with different compound cutting tool. The existing patents and research are most brazed cutting tool now, and most using different cutting parameters, so has yet to have the same compound tool at present. Practice shows that this cutting tool can greatly enhance the machining accuracy of the hole, collect the machining workstages, reduce the accessorial processing time like changing tool, setting tool and so on, significantly improve the efficiency, reduce the cost and relieve the labour intensity of the workers. In addition, we can change the structure and the material of the cutting tool, and the application of the cutting tool is wide.
