External diameter.
The cutter hub is divided into inner segment and outer section, and the external diameter of the cutter hub inner segment is more than the external diameter of the outer section of cutter hub, stepped hole into
Type reamer is fixed on inner segment, and Slot shaping knife is fixed in section outside.
The external diameter of the Slot shaping knife is less than the internal diameter in the hole of workpiece to be processed.
It is connected between the handle of a knife and cutter hub by flange arrangement.
A kind of processing technology using process cutter in the hole, comprises the following steps：
1) workpiece to be processed is positioned, cutter is fixed on machine tool chief axis by hole to be processed straight up；
2) circular interpolation is walked by cutter and processes annular groove；
3) machine tool chief axis and center cutter return to processed hole center, and the downward linear interpolation cutting of cutter processes step
Hole；
4) cutter is exited.
The present invention compared with prior art, with advantages below：
By the present invention cutter can be directly to workpiece stepped hole and hole in annular groove be processed, without more
Different cutters are changed, the positioning number of times of cutter is reduced, improves machining accuracy, simplify process, processing effect is improved
Rate.

Rank hole.
Embodiment
Below against accompanying drawing, by the description to embodiment, the embodiment to the present invention makees further details of
Explanation.
As shown in Figures 1 to 4, process cutter in the hole, including handle of a knife 1, cutter hub 2, shaping blades, wherein, handle of a knife 1
Positioned at the one end of cutter hub 2, shaping blades are located at the other end of cutter hub 2, are connected between handle of a knife 1 and cutter hub 2 by flange arrangement, are easy to tear open
Replacing cutter hub is unloaded, handle of a knife 1 is connected with machine tool chief axis, cutter is fixed on machining tool.
Shaping blades include stepped hole forming reamer 3 and Slot shaping knife 4, and Slot shaping knife 4 is fixed on cutter hub outermost end, step
Hole forming reamer 3, which is fixed on cutter hub 2, is located at the inner side of Slot shaping knife 4.
Cutter hub 2 is divided into inner segment and outer section, and the external diameter of cutter hub inner segment is more than the external diameter of the outer section of cutter hub, stepped hole forming reamer 3
It is fixed on inner segment, Slot shaping knife 4 is fixed in section outside, the external diameter of stepped hole forming reamer 3 is more than the external diameter of Slot shaping knife 4.
The external diameter of Slot shaping knife 4 is less than the internal diameter in the hole of workpiece to be processed 5, is easy to Slot shaping knife 4 to enter workpiece to be processed
Hole inside carry out annular groove processing, wherein, Slot shaping knife is Slot shaping milling cutter.
It is connected between handle of a knife and cutter hub by adjustable structure.Adjustable structure includes corresponding cutter hub flange and handle of a knife method
Orchid, cutter hub flange is provided with fixing hole corresponding with handle of a knife flange upper screwed hole, and bolt is engaged through fixing hole with bolt hole,
There is regulation gap between bolt and fixing hole.
Positioning boss of the cutter hub flange provided with protrusion, handle of a knife flange is provided with the detent relative with positioning boss,
