Groove milling cutter

Abstract

The invention discloses a groove milling cutter, and relates to the technical field of milling cutters. The groove milling cutter comprises a cutter handle and a cutter head which is coaxially fixed at one axial end of the cutter handle, at least two blades are uniformly distributed in the circumferential direction of the cutter head, a containing groove is coaxially formed in one end, close to the cutter handle, of the cutter head, the cutter handle covers an opening of the containing groove, a liquid inlet hole which communicates with the containing groove is formed in the cutter handle in the axial direction; the cutter head is further provided with a plurality of liquid discharging holes, the liquid discharging holes correspondingly communicate with the circumferential inner wall of the containing groove, the number of the liquid discharging holes corresponds to the number of the blades, and the liquid discharging holes face the positions, away from the axis of the cutter head, ofthe blades. According to the groove milling cutter, the liquid inlet hole, the containing groove and the liquid discharging holes are formed, so that the blades make more sufficient contact with cooling liquid in the groove milling process of the groove milling cutter, and the cooling effect of the blades is better; and in addition, the cooling liquid sprayed out at a high speed can further carryout impact on cuttings, so that the situation that the cuttings are stuck to the cutter is reduced, and overall use is more stable.

Description

technical field [0001] The invention relates to the technical field of milling cutters, more specifically, it relates to a slot milling cutter. Background technique [0002] A milling cutter is a rotating tool with one or more teeth for milling. Slot milling cutters are mainly used for grooving the workpiece. [0003] For example, the Chinese patent whose patent notification number is CN206605088U discloses a slot milling cutter, which includes a handle, the upper part of the handle is provided with a clamping end, and the lower part of the handle is provided with a cutter head, and the outer wall of the cutter head is Concave along the radial direction to form a plurality of knife slots, all the knife slots are arranged at intervals along the circumferential direction of the cutter head, and each knife slot extends upward or downward along the axial direction of the cutter head to form an opening, and each is placed in the knife slot Each is equipped with a blade, the mai...

AI Technical Summary

Problems solved by technology

[0004] When the above-mentioned slot milling cutter is used, it is usually necessary to use an external tube to spray coolant on the milling part of the blade. However, during the slotting process, especially when slotting into the hole, the blade extends into the hole and is embedded in the hole during the milling process. In the groove, the coolant sprayed by the external pipe is usually blocked by the groove wall, so that the contact between the coolant and the cutting part of the blade is not good, the cooling effect of the blade is not good, and the service life of the milling cutter blade is affected, which needs to be improved
