Embodiment Construction

[0029] Below in conjunction with accompanying drawing, this technology is further described:

[0030] see figure 1 , figure 2 As shown, generally speaking, this kind of drilling machine includes a horizontally arranged base 1, a rotary table 2 that is parallel to the base 1 and rotated on the base 1, and a column 5 whose axis is parallel to the rotary axis of the rotary table 2 is fixedly connected to the rotary table. On the workbench 2, move the large carriage 7 arranged on the column 5 along the axial direction of the column 5 when moving, and move the small carriage 10 arranged on the large carriage 7 perpendicular to the axial direction of the column 5 when moving. Cutting device on the small carriage 10 (see also Figure 5-11 shown); the cutting device includes a cutting motor 19, a hydraulic power head 20 connected with the cutting motor 19 through a reduction gear 20, and the feeding amount of the hydraulic power head 20 along the vertical and intersecting direction...
