Stainless steel parts processing is challenging due to its material properties, among which cutting temperature control and coolant use are key links to ensure processing quality and efficiency. Stainless steel has high strength, high hardness and good corrosion resistance, but it also means that a large amount of cutting heat is easily generated during processing, resulting in increased tool wear, thermal deformation of the workpiece and decreased surface quality. Therefore, it is crucial to reasonably control cutting temperature and effectively use coolant.The control of cutting temperature first depends on reasonable cutting parameter settings. Cutting speed, feed rate and cutting depth are the main factors affecting cutting temperature. For stainless steel, it is usually recommended to use a lower cutting speed and moderate feed rate to reduce heat generation. At the same time, the selection of cutting depth also needs to balance processing efficiency and cutting temperature to avoid excessive tool load and high cutting temperature caused by too deep cutting.In the cutting process, the use of coolant is an effective means to reduce cutting temperature, reduce tool wear and improve processing quality. Coolant takes away the heat in the cutting area, reduces the temperature of the workpiece and tool, thereby extending tool life and improving processing accuracy and surface quality. For stainless steel processing, the commonly used coolants are water-based coolants and oil-based coolants. Water-based coolants are suitable for most cutting processes and can effectively reduce cutting temperatures and prevent tool overheating. Oil-based coolants can provide better lubrication and tool protection under high temperature and high load processing conditions, especially for precision processing or fine surface treatment.The following points should also be noted when using coolants: First, keep the coolant within the appropriate temperature range to avoid excessively high or low temperatures affecting the cooling effect; second, ensure that the flow of the coolant is sufficient and uniform to cover the cutting area, and the spray angle and spray pressure also need to be adjusted according to the processing process; third, replace the coolant regularly to avoid coolant deterioration or impurities mixed in to affect the cooling and lubrication effects.In addition, in view of the particularity of stainless steel processing, advanced cooling technologies such as spray cooling and internal circulation cooling can also be used. Spray cooling sprays coolant into the cutting area through high-pressure spray, which can quickly take away heat and is suitable for high-speed cutting. Internal circulation cooling transports coolant through the inside of the tool, which can provide continuous cooling in the tool cutting area and is suitable for situations that require longer cutting time or high temperature load.In summary, the control of cutting temperature and the use of coolant in the process of stainless steel parts processing are the key to ensure processing quality and efficiency. By setting reasonable cutting parameters, selecting suitable coolant and adopting advanced cooling technology, the cutting temperature can be effectively reduced, tool wear can be reduced, and processing quality and efficiency can be improved.
