For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0031] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] Embodiment 1: This embodiment provides a coaxial double cutter head for optical film / plate milling, and its structure is as shown in FIG. Figure 5 , including an outer cutter disc 10 and an inner cutter disc 20 arranged in the axial hole of the outer cutter disc 10, and the inner cutter disc 20 and the outer cutter disc 10 are coaxially fixedly arranged.

[0033] The outer and inner cutter discs are made of high-strength, high-wear-resistant metal materials to ensure good stability and durability during high-speed rotation and milling. At the same time, the size of the cutter disc is designed according to specific processing requirements to accommodate optical films of different specifications.

[0034] The processed end surface of the outer cutter disc 10 is evenly provided with four first cutter grains 11 , and the processed end surface of the inner cutter disc 20 is evenly provided with four second cutter grains 21 .

[0035] The outer and inner cutter discs are made of high-strength, high-wear-resistant metal materials to ensure good stability and durability during high-speed rotation and milling. At the same time, the size of the cutter disc is designed according to specific processing requirements to accommodate optical films of different specifications.

[0036] The cutting edge of the second cutter is flush with the cutting edge of the first cutter. This design enables the inner and outer cutter discs to process simultaneously. The outer cutter disc performs roughing operations, while the inner cutter disc performs fine milling operations. This allows for rapid milling operations in one pass, while ensuring surface processing quality and improving processing efficiency and quality.

[0037] Preferably, in the coaxial double cutter disc for milling optical films / plates of the present embodiment, the machining end surface of the outer cutter disc 10 is evenly provided with a plurality of first mounting grooves 12, and the first cutter grains 11 are inserted into the first mounting grooves 12. The side wall of the outer cutter disc 10 is provided with a plurality of radial first countersunk holes 13, the first countersunk holes 13 are connected to the first mounting grooves 12, and screws for locking the first cutter grains 11 are provided in the first countersunk holes.

[0038] Preferably, in the coaxial double cutter disc for milling optical films / plates of the present embodiment, the processing end surface of the inner cutter disc 20 is evenly and fixedly connected with four second cutter grains 21 .

[0039] When installing the blade, the screw is passed through the first countersunk hole and screwed on the first blade, thereby firmly locking the blade. This locking structure is not only simple and easy to operate, but also can ensure that the blade will not fall off or loosen during high-speed rotation and milling.

[0040] Embodiment 2: Different from Embodiment 1, in this embodiment, the inner cutter disc 20 can be inserted into the axial hole of the outer cutter disc 10 in a telescopic manner.

[0041] The inner cutter disc is designed to be retractably installed in the shaft hole of the outer cutter disc, and its stable retraction and extension in the shaft hole of the outer cutter disc is achieved through a precise sliding and locking mechanism.

[0042] In order to ensure the stability and accuracy of the inner cutter disc during the extension and retraction process, refer to Figure 1-4, this embodiment also designs a slot structure. Specifically, a guide slot is provided on the inner wall of the shaft hole of the outer cutter disc 11, and a guide block matching the guide slot is provided on the outer wall of the inner cutter disc. When the inner cutter disc is extended and retracted in the outer cutter disc, the guide block slides along the guide slot, thereby achieving stable axial extension and retraction. The design of this slot structure not only improves the stability of the entire cutter disc, but also ensures the accuracy and reliability of the inner cutter disc during the extension and retraction process.

[0043] In order to ensure that the inner cutter disc can rotate synchronously with the outer cutter disc and realize the lifting and lowering of the inner cutter disc, the milling machine spindle selected in this embodiment is hollow, and a telescopic rod is arranged in the hollow spindle, one end of the telescopic rod is connected to the inner cutter disc through a rotary joint, and the other end is connected to the action output end of the linear driver, such as an electric push rod or a linear motor. These drivers have the characteristics of high precision, high speed and high reliability, and can meet the requirements of the telescopic action of the inner cutter disc.

[0044] The fixed end of the linear actuator is installed on the main shaft moving drive device, and moves with the main shaft, but does not rotate. Therefore, its weight and center of mass position have no effect on the rotation balance of the cutter disc. Thus, the integration of rotation and telescopic is realized.

[0045] Preferably, in the coaxial double cutter disc for milling optical films / plates of the present embodiment, the processing end surface of the outer cutter disc 10 is evenly provided with four or more first mounting grooves 12, and the first cutter grains 11 are inserted into the corresponding first mounting grooves 12. The side wall of the outer cutter disc 10 is provided with a plurality of radial first countersunk holes 13, the first countersunk holes 13 are correspondingly connected to the first mounting grooves 12, and screws for locking the first cutter grains 11 are provided in the first countersunk holes.

[0046] Preferably, in the coaxial double cutter disc for milling optical films / plates of the present embodiment, the processing end surface of the inner cutter disc 20 is evenly provided with four or more second mounting grooves 22, and the second cutter grains 21 are inserted into the corresponding second mounting grooves 22. The side wall of the inner cutter disc 20 is provided with a plurality of radial second countersunk holes 23, and the second countersunk holes 23 are correspondingly connected to the second mounting grooves 22.

[0047] When installing the blade, the screw is passed through the first countersunk hole or the second countersunk hole and screwed on the first blade or the second blade, thereby firmly locking the blade. This locking structure is not only simple and easy to operate, but also can ensure that the blade will not fall off or loosen during high-speed rotation and milling.

[0048] When the cutting edge of the second cutter is flush with the cutting edge of the first cutter, this method enables the inner and outer cutter discs to process simultaneously, with the outer cutter disc performing roughing operations and the inner cutter disc performing fine milling operations.

[0049] When the second knife grain protrudes outward from the first knife grain, it is suitable for milling products with small space.

[0050] The extension length is adjusted according to the processing requirements, thereby adjusting the milling thickness feed. Under the condition of constant rotation speed and tool speed, the thinner the milling thickness, the better the surface processing quality of the optical diaphragm, and the higher the processing quality of the optical diaphragm.

[0051] In addition, different heights of the inner cutter disc may also affect the processing range. For the processing of certain complex shapes or specific areas, it is necessary to adjust the height of the inner cutter disc to achieve more accurate or more comprehensive cutting, such as simultaneously cleaning and machining planes at different heights.

[0052] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
