Described cutter hub is divided into inner segment and outer section, and the external diameter of described cutter hub inner segment is greater than the external diameter of the outer section of cutter hub, and stepped hole forming reamer is fixed on inner segment, and Slot shaping cutter is fixed on outer section.
The external diameter of described Slot shaping cutter is less than the internal diameter in the hole of workpiece to be processed.
Described handle of a knife is connected by flange arrangement with between cutter hub.
Utilize a processing technology for process cutter in described hole, comprise the following steps:
1) located by workpiece to be processed, cutter straight up, is fixed on machine tool chief axis by hole to be processed;
2) walk circular interpolation by cutter and process cannelure;
3) machine tool chief axis and center cutter get back to center, processed hole, and the downward linear interpolation of cutter cuts, and processes stepped hole;
4) cutter is exited.
The present invention compared with prior art, has the following advantages:
Directly can be processed the annular groove in the stepped hole of workpiece and hole by cutter of the present invention, without the need to changing different cutters, decrease the location number of times of cutter, improve machining accuracy, simplify process, improve working (machining) efficiency.
