As shown in fig. 1, in one embodiment, a milling cutter head 10 includes a disc mill 100 and an end mill 200. The disc milling cutter 100 is of a disc-shaped structure, the end mill 200 is of a cylindrical structure, one side of the disc milling cutter 100 is connected with one end of the end mill 200, the radial surface of the disc milling cutter 100 is perpendicular to the axial direction of the end mill 200, the cutter groove 101 is formed in the circumferential surface of the disc milling cutter 100, a cutter seat 102 is arranged on the side wall of the cutter groove 101, a milling cutter block 103 is arranged on the cutter seat 102, one end, away from the end mill 200, of the disc milling cutter 100 is provided with a transmission shaft 300, the transmission shaft 300 is used for being connected with a milling machine, the end mill 200 is provided with a cutter head end 201 and a cutter handle end 202, the cutter handle end 202 is connected with one side of the disc milling cutter 100, and the cutter head.

Specifically, the disc milling cutter 100 has a plurality of cutter grooves 101 formed in a circumferential surface thereof, the cutter grooves 101 are equidistantly distributed on the circumferential surface of the disc milling cutter 100, and notches of the cutter grooves 101 face in the same direction of the disc milling cutter 100, for example, the notches of the cutter grooves 101 face in a clockwise direction or the notches of the cutter grooves 101 face in a counterclockwise direction. The side walls of the tool grooves 101 are respectively provided with a tool holder 102, each tool holder 102 is respectively and fixedly provided with a milling tool block 103, and the milling tool block 103 is provided with a cutting edge which is used for milling a workpiece. A transmission shaft 300 is arranged at one end of the disc milling cutter 100, which is far away from the end mill 200, the transmission shaft 300 is used for being connected with a motor of a milling machine, and the transmission shaft 300 drives the disc milling cutter 100 and the end mill 200 to rotate, so as to mill a workpiece. The end mill 200 comprises a head end 201 and a shank end 202, the head end 201 being provided with a cutting edge for milling a workpiece. By the arrangement, when the disc milling cutter 100 is needed, the milling cutter block 103 on the side edge of the disc milling cutter 100 can be used for milling; when the end mill 200 is needed, the end mill 200 is milled using the bit end 201. Therefore, the original milling cutter does not need to be disassembled and then a new milling cutter is installed, so that the time and the labor are saved, and the processing efficiency is improved.

In order to enable the bottom of the milling insert block 103 of the disc mill 100 to mill a workpiece, in one embodiment, the disc mill 100 is threaded with the end mill 200. Specifically, a connecting hole is formed in one side of the disc milling cutter 100, which is connected to the end milling cutter 200, a first thread is arranged on the side wall of the connecting hole, a second thread is arranged at the shank end 202 of the end milling cutter 200, the shank end 202 is arranged in the connecting hole, and the second thread of the shank end 202 is in threaded connection with the first thread. By arranging the disc milling cutter 100 and the end milling cutter 200 in a threaded manner, when the disc milling cutter 100 is needed, the end milling cutter 200 can be directly disassembled, and a workpiece can be milled by using the bottom of the milling cutter block 103 of the disc milling cutter 100; when the end mill 200 is used, the edge of the end mill 200 can be used to mill a workpiece by directly mounting the end mill 200.

In order to allow the end mill 200 to better mill a workpiece, in one embodiment, the cutting edge provided at the cutting head end 201 of the end mill 200 is a helical cutting edge 203. Specifically, the helical cutting edge 203 is coiled around the tip end 201 of the end mill 200. The spiral cutting edge 203 comprises a main cutting edge and a secondary cutting edge, wherein the main cutting edge is positioned at the bottom of the spiral cutting edge 203, and the secondary cutting edge is positioned at the side edge of the spiral cutting edge 203. The primary cutting edge may be used for milling the surface of a workpiece and the secondary cutting edge may be used for milling the side wall of a groove of a workpiece. By providing the cutting edge of the nose end 201 as a helical cutting edge 203, the end mill 200 can better mill various workpieces.

In one embodiment, at least two helical cutting edges 203 are provided on the tip end 201. The number of the helical cutting edges 203 determines the milling effect of the end mill 200. When the number of the screw type blades 203 is smaller, the larger the interval between the screw type blades 203, the more easily the cut scraps are discharged, and the contact area between the screw type blades 203 and the workpiece is smaller, so that the force required to push the blades to cut the workpiece is smaller, and the longitudinal feed processing is easier. Conversely, when the number of the screw type blades 203 is larger, the pitch between the screw type blades 203 is smaller, the discharging of the cut scraps becomes more difficult, and the contact area between the screw type blades 203 and the workpiece is larger, so that a larger force is required to push the blades to cut the workpiece, and thus the longitudinal feeding process is more difficult.

In order to facilitate the exchange of the milling insert block 103, in one embodiment, the insert seat 102 of the disc mill 100 is fixedly connected to the milling insert block 103 by means of bolts 105. Specifically, the tool holder 102 is provided with a screw hole, and a side wall of the screw hole is provided with a thread. A through hole is formed in the middle of the milling cutter block 103, and the bolt 105 penetrates through the through hole to be in threaded connection with the screw hole. By such an arrangement, when the milling cutter block 103 needs to be replaced, the milling cutter block 103 can be removed by removing the bolt 105, so that the milling cutter block can be replaced.

In order to enable the milling insert 103 of the disc milling cutter 100 to mill a workpiece better, in one embodiment the milling insert 103 is at least partially placed outside the pocket 101. Specifically, the edge portion of the milling insert 103 protrudes out of the pocket 101. By means of the milling insert 103 thus arranged, the milling insert 103 can better mill a workpiece.

In order to prevent the shavings of the milling cutter block 103 from flying apart when the disc milling cutter 100 mills a workpiece, in one embodiment, the milling cutter block 103 is provided with a chip removal groove 104. The chip groove 104 is located on the milling cutter block 103, the side wall of the chip groove 104 is set to be a smooth arc shape, and the arc-shaped side wall is connected to the cutting edge of the milling cutter block 103. The milling cutter block 103 is arranged in such a way that when the disc milling cutter 100 mills, the cut waste chips are discharged along the arc-shaped side wall of the milling cutter block 103 without splashing everywhere.

In one embodiment, the end mill 200 is perpendicular to the disc mill 100. The disc cutter 100 is parallel to the workpiece, and when the end mill 200 is perpendicular to the disc cutter 100, the cutting head 201 of the end mill 200 can be milled perpendicular to the workpiece, so that the end mill 200 can avoid deviation of milling positions during milling.

In order to prevent the waste material skived by the end mill 200 from bouncing up and wearing the milling insert 103 of the disc mill 100, in one embodiment the cutting head end 201 of the end mill 200 is at least 15 cm from the disc mill 100. When the cutting tip 201 of the end mill 200 is at least 15 cm from the disc mill 100, the disc mill 100 can avoid ejection of the shavings cut by the end mill 200, which can protect the disc mill 100 well.
