1, The necessity of cutting fluid in milling aluminum
Reduce cutting temperature: During the milling process, the friction between the tool and the workpiece generates a large amount of heat, leading to an increase in temperature in the cutting area. Excessive cutting temperature not only affects machining accuracy and surface quality, but also accelerates tool wear. Cutting fluid can effectively reduce cutting temperature and protect tools and workpieces from thermal damage.
Reduce friction and wear: Cutting fluid can form a lubricating film between the tool and the workpiece, reducing the friction coefficient and cutting force, thereby reducing tool wear and extending tool life.
Chip removal and cooling: If the chips generated during the cutting process cannot be discharged in a timely manner, it will affect the machining quality and efficiency. Cutting fluid can flush the cutting area, assist in chip removal, and maintain the cooling state of the cutting area.
Improving machining quality: The use of cutting fluid can improve the roughness of the machined surface, reduce residual stress after machining, and enhance machining accuracy and surface quality.
2, Principles for selecting cutting fluid
Compatibility with aluminum: Cutting fluid should have good compatibility with aluminum to avoid corrosion or discoloration of the workpiece.
Lubrication and cooling performance: Cutting fluid should have good lubrication and cooling performance to meet specific requirements when milling aluminum.
Environmental friendliness: With the increasing awareness of environmental protection, the environmental friendliness of cutting fluids is receiving more and more attention. Non toxic, biodegradable or easy to handle cutting fluids should be selected to reduce their impact on the environment.
Economy: The cost of cutting fluid is also one of the factors to consider when choosing. On the premise of ensuring the machining effect, it is advisable to choose cutting fluids with lower costs as much as possible.
3, The effectiveness of cutting fluid in milling aluminum
Improving machining efficiency: The use of cutting fluid can reduce cutting force and cutting temperature, alleviate tool wear, and thus improve machining efficiency.
Extending tool life: The lubrication and cooling effects of cutting fluid can protect the tool from thermal damage and mechanical wear, thereby extending the tool's service life.
Improving machining quality: The use of cutting fluid can improve the roughness and accuracy of the machined surface, and enhance machining quality.
Reduce production costs: Although cutting fluid itself has a certain cost, it can indirectly reduce production costs by improving machining efficiency, extending tool life, and improving machining quality.
4, Precautions
Regularly replace cutting fluid: Cutting fluid will gradually deteriorate and contaminate during use, affecting the effectiveness of use. Therefore, cutting fluid should be replaced regularly to maintain its cleanliness and effectiveness.
Reasonably control the amount of cutting fluid: The amount of cutting fluid should be moderate, as too much or too little can affect the effectiveness of use. Excessive amounts will increase costs and processing difficulty, while insufficient amounts will prevent the full utilization of cutting fluid.
Pay attention to the recycling and disposal of cutting fluid: Effective measures should be taken to recycle and dispose of recyclable cutting fluid to reduce waste and environmental pollution.
