Drilling machine of Multi-axis in the application in the production, resolving the commonness to drill the bed to process many a hour of the bore work to pursue the bore to process the wave to take a lot of time .During the graduation project, the design of the six-axis drilling spoke bolt hole for the machine tool, a dedicated machine.This design has mainly solved in the multi-axis drilling machine processing process two big subject matters: 1: many stalks of the design drill the bed to process the tool machine for Spoke of a wheel stud bolt bore; 2: belonging to the appropriation tool machine. Introduced many stalks to drill the...
