This part is made of SUS304 material,without any surface treatment.The processing of this part is relatively simple:turning the outer shape and then drilling side holes to complete the part.The biggest challenge for this part is how to maximize machining efficiency as much as possible.SUS304 austenitic stainless steel is widely used in industrial fields due to its excellent corrosion resistance and workability.However,its low thermal conductivity and tendency to work harden present challenges in the machining process.Here are the key points for machining SUS304:

• Tool Selection:It is recommended to use coated tools to improve heat resistance and wear resistance,extend tool life,and reduce wear.

• Cutting Speed:Based on the hardness and thermal conductivity of SUS304,the recommended cutting speed is 160-180 meters per minute to avoid overheating and wear while ensuring efficiency.

• Feed Rate:To balance tool wear and workpiece surface finish,the recommended feed rate is 100-200 meters per minute.Too high can cause edge wear,while too low increases surface roughness.

• Cutting Depth:It should be determined based on tool size and performance;too large can lead to tool breakage,while too small reduces efficiency.

• Use of Cooling Fluid:The use of a cooling fluid or lubricant during the machining process reduces heat buildup,extends tool life,and improves chip evacuation.

• Machining Techniques:Light cutting,using small cutting depths and high feed rates,and maintaining tool sharpness are all important techniques for achieving good machining results.

These points help optimize the machining process of SUS304,improving efficiency and the quality of the finished product.
