Meanwhile, the terms such as "upper", "lower", "left", "right", "middle", and the like used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be considered as the scope of the present invention without substantial changes in the technical content.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.

As shown in fig. 1-3, the utility model discloses a take dense tooth milling cutter of chip separation groove, including columniform handle of a knife 1 with integrative the cutter body 2 of fixing in handle of a knife 1 bottom, the external screw of cutter body 2 is equipped with nine chip grooves 3, chip grooves 3 establish to the rake face towards the face of 2 direction of rotation of cutter body, the rake face intersects with 2 outer peripheral faces of cutter body and forms periphery sword 4, the face that meets with periphery sword 4 in the 2 outer peripheral faces of cutter body is first back knife face 5 (be adjacent two rows of chip grooves 2 outer peripheral face parts of cutter body between 3), the face of chip grooves 3 direction of rotation of cutter body dorsad is second back knife face 6.

A plurality of inward concave chip separating grooves 7 are formed in the first rear cutter face 5 at intervals, the chip separating grooves 7 in the two adjacent first rear cutter faces 5 are staggered mutually, two ends of each chip separating groove 7 penetrate through the front cutter face and the second rear cutter face 6, a cutting edge 8 with a triangular cutting edge tip is arranged in each chip separating groove 7, the cutting edge 8 divides the inside of each chip separating groove 7 into an upper groove and a lower groove, a herringbone channel is formed in each chip separating groove 7, and the cutting edge of each cutting edge 8 points to the peripheral edge 4 but does not exceed the front cutter face. The length of the cutting edge 8 is two thirds of the length of the chip flute 7. The width of the chip separation groove 7 is gradually increased (is trapezoidal) from the front cutter face to the second rear cutter face 6. The depth of the chip separation groove 7 is gradually increased from the front cutter face to the second rear cutter face 6, so that chip separation and heat dissipation are facilitated. The cutting edge 8 is arranged inside the chip flute 7 close to the second flank 6, i.e. the cutting edge 8 is shorter in length than the chip flute 7.

When the cutter body 2 rotates, long cuttings cut by the peripheral blade 4 are primarily cut by the end part of the chip dividing groove 7 (cut by the peripheral blades 4 at two ends of the notch of the chip dividing groove 7) and then enter the chip dividing groove 7, the cuttings further move along the herringbone channel of the chip dividing groove 7 along with the rotation of the cutter body 2 and then touch the cutting blade 8, the cuttings are further cut by the cutting blade 8, the cuttings are cut finely (the chip dividing groove 7 is prevented from being blocked or clamped) to form fine particles, and the fine particles are divided by the cutting blade 8 and then are divided into two parts to be discharged into the chip discharge groove 3 and then are discharged to the outside by the chip discharge groove 3. When the double-groove structure of the chip dividing groove 7 is used for dividing chips, due to the action of gravity, particles in the upper groove body of the chip dividing groove 7 are less than particles in the lower groove body of the chip dividing groove 7, the loose space of the upper groove body provides space for circulation of cooling media (air or cooling liquid), and the heat of the front peripheral blade 4 and the area nearby the front peripheral blade can be taken away by the flowing of the cooling media, so that the heat exchange is accelerated, the heat dissipation efficiency is improved, and the temperature of the cutter body 2 is ensured to be within a normal range.

It should be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

The protection scope of the present invention is not limited to the technical solution disclosed in the specific embodiment, and all the modifications, equivalent replacements, improvements, etc. made by the technical entity of the present invention to the above embodiments all fall into the protection scope of the present invention.
