Description

Technical Field

[0001] This utility model relates to tools used in precision machining, and more particularly to precision machining cutting tools, specifically a wave-shaped profile cutting tool. Background Technology

[0002] Currently used tapered contour cutters mostly have a tapered body with 4-6 spiral grooves on the surface to ensure stability during forming. However, the spiral grooves prevent effective lubrication and cooling when machining deeper areas, affecting machining position accuracy and tool life.

[0003] Therefore, it is necessary to provide a wave-shaped profile cutting tool to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a wave-shaped profile cutting tool.

[0005] The technical solution is as follows:

[0006] A wave-shaped profile cutting tool includes a shank connected to a tool body. The tool body is conical in shape and has three wave-shaped cutting edges. Each wave-shaped cutting edge is fan-shaped at 25-35° and is evenly distributed around the center of the tool body at 360°, forming a stable machining edge contact structure with smooth connection at three points. The wave-shaped cutting edge includes a peak machining edge, and an arc-shaped chip groove is provided corresponding to the peak machining edge. A sloping chip breaking section is also provided between the peak machining edge and the arc-shaped chip groove.

[0007] Furthermore, the diameter of the end of the blade body is one-third of the diameter of the beginning of the blade body.

[0008] Furthermore, the tapered slope of the blade body is no greater than 30°.

[0009] Furthermore, an arc-shaped chip accumulation groove is provided between adjacent wave-shaped cutting edges.

[0010] Furthermore, the spacing between the bottom of each arc-shaped chip groove corresponding to the wave-shaped cutting edge is one-third of the bottom diameter of the current arc-shaped chip groove.

[0011] Furthermore, the three wave-shaped cutting edges have wavy toothed surfaces, with the peak spacing being A and the peak-to-trough spacing being B.

[0012] Furthermore, A is 1-2 mm, and B is 0.1-0.3 mm.

[0013] Compared with the prior art, this utility model, through three evenly distributed wave-shaped cutting edges, can stably and smoothly connect the processing parts, while ensuring that the cooling and lubricating fluid can smoothly enter the processing area for cooling or lubrication, thus ensuring processing accuracy and tool life.

[0017] Example:

[0018] Please see Figure 1-3 This embodiment demonstrates a wave-shaped profile cutting tool, including a shank 1, a tool body 2 connected to the shank, the tool body 2 being conical in shape, and three wave-shaped cutting edges 3 being provided on the tool body 2. Each wave-shaped cutting edge 3 is fan-shaped at 25-35° and is evenly distributed around the center of the tool body 2 at 360°, forming a stable machining edge contact structure with smooth connection at three points. The wave-shaped cutting edge 3 includes a peak machining edge 31, and an arc-shaped chip groove 32 is provided corresponding to the peak machining edge 31. A slope chip breaking section 33 is also provided between the peak machining edge 31 and the arc-shaped chip groove 32.

[0019] The diameter of the end of the blade body 2 is one-third of the diameter of the beginning of the blade body 2.

[0020] The tapered slope of the blade body 2 is no greater than 30°.

[0021] An arc-shaped chip accumulation groove 4 is provided between adjacent wave-shaped cutting edges 3.

[0022] The spacing between the bottom of each arc-shaped chip groove 33 corresponding to the arc-shaped chip groove 4 is one-third of the bottom diameter of the current arc-shaped chip groove 33.

[0023] The surfaces of the three wave-shaped cutting edges 3 are wavy toothed surfaces 5, with the peak spacing of the wavy toothed surfaces 5 being A and the peak-to-trough spacing being B.

[0024] A is 1-2mm, and B is 0.1-0.3mm.

[0025] Compared with the prior art, this utility model, through three evenly distributed wave-shaped cutting edges, can stably and smoothly connect the processing parts, while ensuring that the cooling and lubricating fluid can smoothly enter the processing area for cooling or lubrication, thus ensuring processing accuracy and tool life.

[0026] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
