[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a milling cutter for processing golf club heads, comprising a handle portion 1 and a blade portion 2 arranged at one end of the handle portion 1, the blade portion 2 being provided with a plurality of teeth 20, a plurality of positioning ends 21 for positioning the teeth 20 being provided between the handle portion 1 and the blade portion 2, the extension line of the positioning ends 21 on the outer peripheral surface of the milling cutter being spiral, the plurality of positioning ends 21 being distributed on the same circumference, the extension lines of the plurality of positioning ends 21 being parallel to each other, and the teeth 20 being evenly spaced on the extension line. Specifically, as Figure 1-Figure 2 As shown, the milling cutter is preferably cylindrical in structure. The handle 1 is the part that connects the milling cutter to the milling machine or machining center. The handle is preferably made of high-strength alloy material to ensure rigidity and durability during high-speed rotation. The blade 2 is covered with a plurality of teeth 20. The teeth 20 are preferably made of tungsten-cobalt cemented carbide, which is particularly suitable for cutting materials with high hardness, such as the raw materials of the carbon fiber cover golf club head. This material has extremely high hardness and good wear resistance, and can withstand high pressure and high temperature during the cutting process. Figure 3-Figure 4 As shown, the positioning end 21 is specifically a protrusion structure between the handle portion 1 and the blade portion 2. There are a plurality of positioning ends 21, which are arranged around the outer peripheral surface of the milling cutter. Figure 4 It can be seen that the extension lines on different positioning ends are parallel to each other, which is convenient for manufacturing. The positioning end 21 plays a role of connection and transition between the handle portion 1 and the blade portion 2. The extension line of the positioning end 21 toward the blade portion 2 is in the shape of a spiral line on the outer peripheral surface of the milling cutter. The teeth 20 are evenly spaced on the extension line. The positioning end 21 is arranged in a spiral shape on the extension line of the outer peripheral surface of the milling cutter. This design helps to improve the stability and uniformity of cutting.

[0023] The extension line of the positioning end of the utility model on the outer circumference of the milling cutter is spiral, and several positioning ends are distributed on the same circumference, and the cutter teeth are evenly spaced on the extension line of the positioning end, which is convenient for production and manufacturing; the extension lines between the positioning ends are parallel to each other, and the cutter teeth are evenly spaced on the extension line of the positioning end. This structural design allows the milling cutter to perform left-handed or right-handed cutting during rotation processing. The positioning end helps to improve the positioning accuracy of the cutter teeth, thereby achieving more precise cutting during the processing process, with faster processing efficiency and no burrs or edges on the processed products.

[0024] Furthermore, the cutter teeth 20 further include a cutting edge portion 200 for machining the carbon fiber cover plate, and the cutting edge portion 200 does not exceed the outer diameter d of the milling cutter. Figure 3 and Figure 4 As shown, the cutting edge portion 200 is located on the extension line of the positioning end 21 on the outer circumference of the blade portion, and the cutting edge portion 200 does not exceed the outer diameter d of the milling cutter, which helps to maintain the stability and consistency of the cutting edge.

[0025] Furthermore, the outer diameter d of the milling cutter is 1.5-6 mm. Figure 2 As shown, the outer diameter d of the milling cutter is 4 mm, which is suitable for processing golf club heads; preferably, the outer diameter d of the milling cutter is 2 mm, which can process golf club heads more finely.

[0026] Furthermore, the blade teeth 20 further include a tooth groove portion 201, and the tooth groove portion 201 connects the adjacent cutting edge portions 200. Specifically, Figure 3 and Figure 4 As shown, the tooth groove portion 201 is a connection structure between the teeth 20 on the same extension line, and the connection structure generally has an inclination. The function of the tooth groove portion 201 is to provide a space for accommodating and removing chips generated during the cutting process. By effectively removing chips, the heat accumulation in the cutting area can be reduced, and the temperature of the tool and the workpiece can be reduced, thereby improving the cutting efficiency, reducing tool wear, and extending the tool life.

[0027] Furthermore, the distance between adjacent teeth 20 on the same extension line is 0.3-0.4 mm. Figure 3 As shown, the distance between adjacent teeth 20 located on the same extension line is preferably 0.35 mm. Appropriate tooth spacing can optimize the formation and removal of chips, reduce cutting resistance, and improve cutting efficiency. A tooth spacing of 0.35 mm helps to generate smaller chips, which can effectively avoid chip blockage and improve cutting efficiency. A tooth spacing of 0.35 mm can improve the smoothness of the machined surface because each tooth removes less material and the cutting is finer.

[0028] Furthermore, the angle between the direction of the blade teeth 20 and the horizontal line is 25-35 degrees. Figure 3 As shown, the angle between the direction of the cutter teeth 20 and the horizontal line is preferably 30 degrees. This angle helps to improve cutting efficiency and chip removal performance and ensure the smoothness of the machined surface.

[0029] Furthermore, a spacer 210 is provided between adjacent positioning ends 21, and the spacer 210 is spirally arranged on the blade portion 2 along the extension line, and the spacer 210 is used for chip removal of adjacent teeth 20. Specifically, Figure 3 and Figure 4 As shown, the spacer 210 can be understood as a connection structure between connected teeth on different extension lines, and is arranged in a spiral shape. The spiral connection structure can further optimize the chip removal effect of the teeth, keep the cutting area clean, and improve processing efficiency.

[0030] Furthermore, the outer surface of the cutter teeth 20 is provided with a diamond coating, which significantly improves the hardness and wear resistance of the cutter teeth, allowing the milling cutter to maintain cutting performance for a long time under high load, thereby extending the service life of the cutter.

[0031] Furthermore, the base material of the milling cutter is high-speed steel, cemented carbide, titanium alloy, etc. Specifically, high-speed steel, cemented carbide, titanium alloy and other materials have the characteristics of high strength, wear resistance and high temperature resistance, and are suitable for complex and high-intensity processing environments.

[0032] Furthermore, the handle portion 1 and the blade portion 2 are integrally formed, which helps to improve the overall rigidity and stability of the milling cutter and reduce vibration and deformation during high-speed cutting.

[0033] The extension line of the positioning end of the utility model on the outer circumference of the milling cutter is spiral, and several positioning ends are distributed on the same circumference, and the cutter teeth are evenly spaced on the extension line of the positioning end, which is convenient for production and manufacturing; the extension lines between the positioning ends are parallel to each other, and the cutter teeth are evenly spaced on the extension line of the positioning end. This structural design allows the milling cutter to perform left-handed or right-handed cutting during rotation processing. The positioning end helps to improve the positioning accuracy of the cutter teeth, thereby achieving more precise cutting during the processing process, with faster processing efficiency and no burrs or edges on the processed products.
