As a high-precision, wear-resistant cutting tool, the flat knife is widely used in the processing of various materials such as aluminum, plastics, castings, copper, aluminum alloys, titanium alloys, etc. During the cutting process, the performance and life of the flat knife not only depend on its own quality and manufacturing process, but also closely related to factors such as cutting conditions, lubrication and cooling methods.
During the cutting process, a large amount of frictional heat will be generated between the tool and the workpiece, causing the tool temperature to rise, which in turn affects the cutting effect and tool life. Therefore, regular lubrication and cooling are particularly important for flat knives.
Lubrication can effectively reduce the friction between the tool and the workpiece, reduce the cutting force and cutting temperature, extend the tool life, and improve the quality of the machined surface. For flat knives, choosing a suitable lubricant is crucial. The lubricant needs to have good permeability, adsorption and film-forming ability, and can form a lubricating film between the tool, chips and the machined surface, thereby reducing the friction coefficient and wear rate.
Cooling mainly removes heat from the cutting area, reduces the cutting temperature, and prevents the tool from overheating and deformation. The cooling performance of the cutting fluid depends on its physical properties such as heat transfer coefficient, specific heat capacity, and heat of vaporization. During the cutting process, the cutting fluid should be able to quickly absorb and take away heat to keep the temperature of the cutting area stable.
For flat knives, the selection of cutting fluid should be determined according to the processing materials, cutting parameters and processing requirements. At the same time, the flow rate, pressure and injection method of the cutting fluid also need to be optimized to ensure that the cutting fluid can evenly and effectively cover the cutting area.
In actual operation, the lubrication and cooling effects of the cutting fluid should be checked regularly according to the processing conditions and tool wear, and the cutting fluid should be replaced or replenished in time. In addition, the cleanliness and stability of the cutting fluid are also important factors affecting the cutting effect, which require regular inspection and maintenance.
In summary, the flat knife needs regular lubrication and cooling during the cutting process to ensure its good cutting performance and extend its service life. Selecting suitable lubricants, optimizing the flow rate and pressure of the cutting fluid, and regularly inspecting and maintaining the cutting fluid system are all important measures to improve cutting efficiency and processing quality.
