1. Stainless steel processing skills

1. Please select the product according to the completion requirements. The common surface treatment types of stainless steel are non -oriented, surface treatment or mirror polishing. Your abrasive selection depends on the requirements of the appearance or average roughness (RA). For coarse grinds, 36 or 40 particles can be used. However, if mirror polishing is needed, it is necessary to further increase the degree of gravel and add some polishing compounds or fiber wheels to polish the material to the required visual effects. Products designed for stainless steel will work more effectively on this material, because compared with carbon steel -designed products, this product has a faster cutting speed, longer service life, and better heat dissipation.

2. Do not cross pollution. Just because the product label for carbon steel or stainless steel, it does not mean that it is pollution -free. A non-polluting product contains less than 0.1 % of iron, and sulfur and chlorine-can cause oxidative elements.

The bonding abrasive product marked as INOX does not contain pollutants. Whether or not polluting products depends on the final requirements of the application. Also important, avoid using a certain product on carbon steel before using the product on stainless steel. If you use a stainless steel brush on the carbon steel and then use the stainless steel brush, pollutants will be introduced from the iron material. A method to avoid cross -pollution when the wheels and brushes look similar are to use rags with color marks. These can help you avoid using a carbon steel brush on stainless steel, and vice versa.

3. Start with the desired trim on the mother material. It is a common practice from the basic materials of pre -processing the required specifications, which can save a lot of operation time and money. For example, sheet metal matrix can be welded by No. 4 directional polishing or mirror polishing by the machine. This can minimize the amount of precise work that must be completed by manually after welding the parts.

4. Don't apply too much pressure. When using grinding products, the pressure is equal to heat, and heat is more likely to damage stainless steel than carbon steel. You can control the grinding or precision processing heat by applying a small pressure and letting the grinding brush or sand wheel designed.

5. Keep the product move. When grinding or refined stainless steel, use a uniform and consistent pattern. Time to stay in a area is too long, which will accumulate heat, which will damage the mother material and cause the increased time and rework.

6. Don't skip safety. The use of the necessary personal protection equipment (PPE) is very important for any welding and metal refinement, especially for stainless steel. It is recommended to use the respirator when processing any steel or stainless steel, because the abrasives and substrates will produce dust. Stainless steel also has a large amount of nickel risk. Nickel will spread to the air with other particles when grinding, which will cause lung damage.

7. Record process. Detailed explanation of the process of gradual stainless steel is important for the results that can be consistent each time. It helps eliminate guessing and reduce the opportunity to work. This is particularly important for the application that requires a very special cleanliness (such as medical or food processing) each time. Your document should include the process you use and the specific abrasive type and particle size of each step.

2. Precautions for processing stainless steel processing

1. Processing area:

The processing area of stainless steel parts should be relatively fixed. The platform of the stainless steel processing area should take isolation measures, such as paving with rubber pads. The setting management and civilization production of the stainless steel processing area should be strengthened to avoid damage and pollution of stainless steel parts.

2. Selection of tool materials:

Due to the large cutting force and high cutting temperature of the stainless steel parts, the tool material should be as high as possible, good thermal conductivity as much as possible. The roughness value of the front knife surface is small. In order to avoid crumbs and sticky knives, the front and rear knives of the tool should be carefully grinded to ensure a small roughness value, thereby reducing the resistance of chip outflow and avoiding crumbs and sticking knives.

3. The selection of cutting fluid should be appropriate:

Because stainless steel has the characteristics of poor bonding and heat dissipation, it is very important to use anti -adhesive and good heat dissipation in the cutting.

4. The feeding:

The feeding of stainless steel parts is cut or plasma cutting, sawing, etc.

4.1. Cutting: When cutting, it should be isolated from the stent, and the foothold should be paved with rubber pads to avoid scratching.

4.2. Plasma cutting: After the plasma is cut, the slag should be cleaned. During batch cutting, the complete parts should be cleaned out of the scene in time to avoid the defilery of the workpiece.

4.3. Saw cutting: When cutting the feed, clamp the tightness should be protected by the rubber. After the saw, the oil pollution and residue on the workpiece should be cleaned.

5. Mechanical processing:

Stainless steel parts should also pay attention to protection during mechanical processing such as cars and milling. The operation should be cleaned up to clean the oil, iron chips and other debris on the surface of the workpiece.

6. For molding processing:

In the process of curling and bending, effective measures should be taken to avoid scratching and creases on the surface of stainless steel parts.

7. Riveting welding:

When stainless steel parts are paired, forced assembly should be avoided, especially for the assembly of flame roasting schools. If the group pair or production process is temporarily cut with a plasma, isolation measures should be taken to avoid the pollution of other stainless steel parts. After cutting, the cutting slag on the workpiece should be cleaned up.

8. Welding:

Before welding stainless steel parts, it must be carefully removed of oil pollution, rust, dust and other debris. During welding, you should use a tadpole to weld as much as possible. Small current and fast welding should be used when hand -made arc welding to avoid swinging. It is strictly forbidden to quote the arc in the non -welding area, the ground line is appropriate and the connection is firm to avoid arc scams. Anti -splashing measures (such as white gray and other methods) should be taken during welding. After welding, stainless steel (carbon steel shall not be used) flat shovels to completely clean the slag and splash.
