Detailed Description

Example (b):

the utility model discloses a structural schematic diagram is shown in fig. 1, the utility model discloses a screw tap die processing professional equipment, including chuck 1, chuck 2, emery wheel 3, electric main shaft 4, workstation 5, electronic box 7, wherein chuck 2 installs on chuck 1, and die 8 installs on chuck 2, and emery wheel 3 installs on electric main shaft 4, and electric main shaft 4 is fixed on workstation 5, and electronic box 7 controls chuck 2, emery wheel 3, electric main shaft 4, workstation 5 work.

In this embodiment, the above-mentioned working table 5 is further provided with a hand wheel 9. The handwheel 9 manually controls the movement of the worktable 5.

In this embodiment, the electric spindle 4 is further provided with a cooling system 6. The cooling liquid of the cooling system 6 enters the electric spindle 4, and the cooling system 6 cools the electric spindle 4. The electric box 7 controls the operation of the cooling system 6.
