[0007] In use, the chisel cutter is fed from right to left, the first rough machining tooth rough machines the right tooth surface of the hob, the second rough machining tooth rough machines the left tooth surface of the hob, and the finishing tooth simultaneously finishes machining the left and right tooth surfaces of the hob (the left and right tooth surfaces can be machined simultaneously because the cutting amount is about 5 or 6 wires in finishing machining), so that the rough and finishing machining of the hob is completed by one feeding of the chisel cutter, the machining efficiency is greatly improved, the service life of the cutter is effectively improved, and the overall machining quality is improved; in addition, because the machining quality of the chisel cutter is high and the error is small, the grinding allowance is correspondingly reduced, so the difficulty of subsequent chisel grinding machining is also reduced.

[0008] Further, the three cutter teeth are cutter teeth machined by wire electrical discharge machining, the tooth shape angle and the roundness precision are high, the machining precision and the surface roughness of the hob are improved, the service life of the cutter is further improved, and the difficulty of subsequent chisel grinding machining is further reduced.

[0009] The chisel cutter has the beneficial effects as follows: the chisel cutter has three cutter teeth, which cleverly realize rough and finishing machining of the hob by one feeding of the chisel cutter, greatly improve the machining efficiency, effectively improve the service life of the cutter, and improve the overall machining quality; in addition, because the machining quality of the chisel cutter is high and the error is small, the grinding allowance is correspondingly reduced, so the difficulty of subsequent chisel grinding machining is also reduced, and the chisel cutter is particularly suitable for machining medium and small modulus hobs.
