In the processing of high-hardness materials, the milling cutter T-Type Knife needs to ensure stable cutting force output, which requires comprehensive consideration from multiple aspects such as material selection, tool design, cutting parameter optimization, and cooling and lubrication.
1. Material selection
High-hardness tool material: T-Type Knife usually uses cemented carbide (such as tungsten steel) or high-performance ceramic materials. These materials have excellent hardness, wear resistance and high-temperature stability, and can keep the tool sharp and durable in the processing of high-hardness materials.
Coating technology: By coating the surface of the tool with a hard coating (such as TiN, TiAlN, DLC, etc.), the wear resistance, anti-adhesion and high-temperature stability of the tool can be further improved, thereby ensuring stable cutting force output.
2. Tool design
Reasonable number of blades and blade shape: The design of the T-Type Knife needs to consider the rationality of the number of blades and blade shape to ensure that the tool can evenly disperse the cutting force and reduce the stress concentration at the tip during the cutting process of high-hardness materials. Usually, a multi-blade design is used to improve cutting efficiency and stability.
Tool rigidity: The tool bar and blade design of the T-Type Knife need to have sufficient rigidity to resist the impact and vibration generated during the cutting process of high-hardness materials, ensuring the stable output of cutting force. Reasonable tool diameter and length design can enhance the overall rigidity of the tool.
Edge treatment: Through precise edge treatment (such as chamfering, grooving, etc.), the distribution of cutting force can be improved, the edge stress can be reduced, and the service life and cutting stability of the tool can be improved.
3. Cutting parameter optimization
Appropriate feed rate and cutting speed: In the processing of high-hardness materials, appropriate feed rate and cutting speed are the key to ensuring the stable output of cutting force. Usually, it is necessary to optimize the cutting parameters according to the specific material hardness and tool performance. Excessive cutting speed may cause the tool to wear too quickly, while too low cutting speed may cause unstable cutting force.
Cutting depth and feed control: Reasonable cutting depth and feed can reduce the impact and vibration during the cutting process and ensure the stability of cutting force. Usually, a layered cutting strategy is adopted to gradually increase the cutting depth to adapt to the processing characteristics of high-hardness materials.
4. Cooling and lubrication
Efficient cooling system: During the cutting process of high-hardness materials, a large amount of heat will be generated between the tool and the workpiece. By using an efficient cooling system (such as external coolant injection or internal coolant channel), the cutting heat can be taken away in time, the temperature of the tool and the workpiece can be reduced, and thermal deformation and tool wear can be reduced, thereby ensuring the stable output of cutting force.
Cutting fluid selection: Selecting a suitable cutting fluid (such as water-based coolant, oil-based coolant or synthetic coolant) can improve the cooling effect and lubrication performance, reduce the friction between the tool and the workpiece, and prevent tool adhesion and wear.
5. Tool maintenance and monitoring
Regular sharpening and replacement: During the processing of high-hardness materials, the tool wears faster. Regular sharpening and replacement of the tool can maintain the sharpness and cutting performance of the tool and ensure the stable output of the cutting force.
Tool status monitoring: By real-time monitoring of the tool wear status and cutting force changes, the cutting parameters can be adjusted in time to avoid the problem of unstable cutting force caused by tool wear.
In the processing of high-hardness materials, the milling cutter T-Type Knife ensures stable cutting force output through comprehensive measures such as material selection, tool design, cutting parameter optimization, cooling and lubrication, and tool maintenance and monitoring. These measures not only improve the service life and processing efficiency of the tool, but also ensure the processing quality and stability, which is an indispensable and important link in the processing of high-hardness materials.
