The machining process of S355 steel plate usually includes the following steps and precautions:
1. Cut (cut, shear):
- Use appropriate knives (e.g. carbide knives) and equipment to make cuts and ensure smooth cuts.
- Control cutting speed and cutting depth to avoid overheating or cut deformation.
2. Drilling:
- Select the appropriate drill material and geometry.
- Control drilling speed, feed rate and cooling method to avoid drill bit damage and improve hole quality.
3. Milling:
- Select appropriate milling tools and parameters to perform roughing and finishing as required.
- Ensure stable clamping and suitable cutting lubrication conditions.
4. Turning:
- Select internal turning, external turning and other operation methods as needed.
- Control cutting speed, feed rate and cutting depth to ensure surface quality and dimensional accuracy.
5.Welding:
- Make sure the welding area is clean and use appropriate welding materials and methods.
- Control welding parameters to avoid cracks and deformation and ensure welding strength and quality.
6. Heat treatment:
For parts that need to increase strength or improve structural properties, heat treatment operations, such as normalizing and tempering, can be performed.
7. Surface treatment:
If surface treatment is required, such as shot peening, grinding, plating, etc., appropriate process methods and materials should be selected according to requirements.
8. Quality control:
- Quality checks are carried out at every processing step to ensure that the processing quality meets the requirements.
- Record each process parameter and quality data for traceability and analysis.
The above are the common machining process steps and precautions for S355 steel plates. The specific operations should be adjusted and optimized according to the actual situation.
