Description

Technical Field

[0001] The utility model relates to the technical field of diamond cutting tools, in particular to a buffer-type diamond cutting tool. Background Art

[0002] In the metal turning, boring and milling industries, parts with long inner holes, deep cavities and other structures are often encountered. The aspect ratio of some parts is as high as 15 times or even higher, which requires a large overhang of the tool. Ordinary tools vibrate very seriously when processing such parts, and cannot guarantee the dimensional accuracy and surface quality of the parts. During the metal cutting process, the tool is subjected to an alternating random load on the cutter head. This alternating random load forces the tool to vibrate. Due to the large overhang of the tool, the static stiffness of the tool body itself is low, the amplitude of the cutter head increases, and the processed surface exceeds the surface roughness requirements of the part. Even when the alternating random load is close to the natural frequency of the tool itself, resonance can occur, which will maximize the vibration of the tool.

[0003] For example, a damping vibration reduction device and a vibration reduction tool (CN211136480U) have been disclosed. The damping vibration reduction device includes a connecting rod, a connecting cover, a base, a first mass body and a second mass body. The connecting cover and the base are respectively arranged at both ends of the connecting rod, and the first mass body and the second mass body are sleeved on the outside of the connecting rod. A first elastic element is arranged between the two, and a second elastic element and a third elastic element are respectively arranged between the first mass body and the connecting cover and between the second mass body and the base. Damping gaps are provided between the first mass body, the first elastic element, the second mass body and the outer wall of the connecting rod. Each damping gap is interconnected, and damping fluid is provided in the damping gap. The vibration reduction tool includes a tool body, a tool head and the above-mentioned damping vibration reduction device. The tool body is provided with a damping vibration reduction accommodating hole adapted to the damping vibration reduction device. The tool head is fixed at one end of the damping vibration reduction device. The utility model has good vibration reduction effect and adjustable vibration reduction performance. When used with a tool, it can effectively alleviate the vibration of the tool.

[0004] However, previous diamond tools had some defects in use. The complex buffer structure not only increased the production cost of diamond tools, but also increased the failure rate of diamond tools during use. As a result, diamond tools were easily affected by damage to the buffer structure during use, which reduced the user's experience with diamond tools and could not meet the needs of today's market.

[0026] Example 2:

[0027] On the basis of embodiment 1, the present invention is as follows Figures 1-4 As shown, it is disclosed that the impact-resistant layer 6 is coated on the outer surface of the base layer 5, the functional layer 7 is coated on the outer surface of the impact-resistant layer 6, the high-temperature resistant layer 8 is coated on the outer surface of the impact-resistant layer 6, the anti-corrosion layer 9 is coated on the outer surface of the high-temperature resistant layer 8, and the wear-resistant layer 10 is coated on the outer surface of the anti-corrosion layer 9. The material of the base layer 5 is high-strength steel, and the material of the impact-resistant layer 6 is titanium nitride material.

[0028] The above technical solution is adopted mainly to achieve the purpose of impact resistance. The specific effects are as follows: Titanium nitride material has the following advantages: Improved hardness and wear resistance: It can increase the surface hardness of diamond tools, making them have better wear resistance and impact resistance, and is suitable for cutting processing of various materials. In ordinary cutting processing, TiN-coated diamond tools can maintain high cutting efficiency and long service life. Higher oxidation temperature: It has a higher oxidation temperature and is not prone to oxidation reaction in high temperature environment, which can maintain the performance of the tool stable. This makes the coating of diamond tools not easy to fail during high temperature processing or high-speed cutting, ensuring the safety and reliability of processing. Good lubricity: TiN coating has certain lubricity, which can reduce the friction between the tool and the workpiece, reduce cutting force and cutting heat, and improve processing efficiency and processing quality. In some occasions with high requirements on processing surface quality, TiN-coated diamond tools can meet processing needs.

The specific effects are: Nitrogen aluminum titanium material has the following advantages: Excellent high temperature performance: The aluminum oxide layer formed in the coating can maintain good stability at high temperatures, so that the tool has excellent oxidation resistance and wear resistance in high temperature processing environments. Therefore, TiAlN coated diamond tools are very suitable for cutting under high temperature conditions such as high-speed dry cutting and high-temperature alloy processing. High hardness and toughness: With high hardness and certain toughness, it can improve the impact resistance and fracture resistance of the tool while ensuring the hardness of the tool. When processing some materials with high hardness and certain toughness, TiAlN coated diamond tools can effectively cut materials without problems such as tool breakage.

Thereby extending the service life of the tool, carbonitride material has the following advantages: good comprehensive performance: combining the advantages of carbon and nitrogen elements, it has both high hardness and wear resistance, and good lubricity and anti-adhesion. During the processing, it can reduce the adhesion between the tool and the workpiece, reduce cutting force and cutting heat, and improve processing efficiency and processing quality. The coating thickness is controllable: the coating process parameters can be adjusted to control the thickness and structure of the coating to meet different processing requirements. When processing some workpieces with complex shapes, the appropriate coating thickness and structure can be selected according to the shape and size of the workpiece to improve the cutting performance and processing accuracy of the tool.
