DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] A slotting and chamfering integrated tool comprises a tool handle 1 and a tool head 2, the tool handle 1 is cylindrical, and the diameter of one end of the cylindrical tool handle 1 gradually decreases toward the end face direction to form a truncated cone shape, the tool head 2 is arranged on the truncated cone-shaped end face formed by the tool handle 1, and the central axis of the tool head 2 in the length direction is collinear with the central axis of the tool handle 1 in the length direction so that the tool handle 1 provides the maximum support force for the tool head 2, so as to improve the stability of the tool head 2 during processing and increase the maximum feed depth of the tool head 2, the end of the tool head 2 is provided with a slotting main cutting edge 21, the side wall of the tool head 2 is provided with a slotting secondary cutting edge 22, and the outer wall of the tool handle 1 corresponding to the truncated cone-shaped portion is provided with a chamfering cutting edge 11, the slotting main cutting edge 21 is tangent to the slotting secondary cutting edge 22 and is vertically arranged, the slotting secondary cutting edge 22 is tangent to the chamfering cutting edge 11 and the angle between the two is less than or equal to 90°. The grooved main cutting edge 21, the grooved secondary cutting edge 22 and the chamfered cutting edge 11 are on the same vertical plane. The cutter head 2 is ground to form a first flank face 23 on one side of the grooved main cutting edge 21, and a first rake face 24 on the other side. The cutter head 2 is ground to form a second flank face 25 on one side of the grooved secondary cutting edge 22, and a second rake face 26 on the other side. The tool handle 1 is ground to form a third flank face 12 on one side of the chamfered cutting edge 11, and a third rake face 13 on the other side. The first rake face 23 is formed as the end face of the cutter head 2 and is inclined in the direction of the tool handle 1. The first rake face 24 is coplanar with the second rake face 26, and the second rake face 25 is tangent to the third rake face 12 and is arranged in a straight surface.

[0017] The main groove cutting edge 21 is used for digging deep grooves for the workpiece, the auxiliary groove cutting edge 22 is used for cutting the side wall of the deep groove to increase the groove width, and the chamfering cutting edge 11 is used for chamfering the upper edge of the deep groove opened in the workpiece. The main groove cutting edge 21, the auxiliary groove cutting edge 22, and the chamfering cutting edge 11 are assembled on the same tool body to reduce tool switching and improve production efficiency. The main groove cutting edge 21 is tangent to the auxiliary groove cutting edge 22, and the auxiliary groove cutting edge 22 is tangent to the chamfering cutting edge 11 to achieve simultaneous groove and chamfering of the workpiece. The alignment and consistency between groove and chamfering are good, the yield is high, which is beneficial to reducing production costs, and chamfering the upper edge of the deep groove is beneficial to removing burrs at the groove mouth.

[0018] The cutter head 2 is ground to form a first avoidance surface 27 on one side of the second back cutting surface 25, and the tool handle 1 is ground to form a second avoidance surface 14 on one side of the third back cutting surface 12. The first avoidance surface 27 is coplanar with the second avoidance surface 14 and is inclined to avoid the side wall of the workpiece during processing, thereby reducing the contact area between the cutter head 2 and the tool handle 1 and the workpiece during processing, which is beneficial to reducing the vibration of the tool during processing and avoiding the occurrence of vibration marks on the workpiece. The first avoidance surface 27 is a straight surface, and the second avoidance surface 14 is a fan-shaped surface that extends from the edge of the truncated cone-shaped portion of the tool handle 1.

[0019] A third avoidance surface 28 is ground and formed on one side of the cutter head 2 and the first avoidance surface 27, and a fourth avoidance surface 15 is ground and formed on one side of the third back cutting surface 12 of the cutter handle 1. The third avoidance surface 28 is coplanar with the fourth avoidance surface 15. The third avoidance surface 28 is a straight surface formed as the side wall of the cutter head 2 away from the first front cutting surface 24, and the fourth avoidance surface 15 is a fan-shaped surface and extends from the edge of the truncated cone-shaped portion of the cutter handle 1.

[0020] The cutter head 2 is provided with a double helical angle groove 29 on the first rake face 24 and the second rake face 26. The double helical angle groove 29 spirally extends downward to the outer wall of the tool handle 1, and one side of the double helical angle groove 29 extends to overlap the slotting secondary cutting edge 22 and the chamfering cutting edge 11. The double helical angle groove 29 is beneficial for chip removal during slotting and chamfering, and reduces the contact surface during cutting, thereby reducing vibration during processing and further avoiding the occurrence of chatter marks on the workpiece. The workpiece has good brightness after processing, and the blade sharpness is increased for efficient cutting.

[0021] The cutter head 2 and the cutter handle 1 are made of the same material, which is tungsten steel carbide. Tungsten steel carbide has excellent wear resistance and extremely high hardness, which makes the tool stable during processing and has a long tool life, and further reduces the vibration of the tool during processing that causes chatter marks on the workpiece.
