Stainless steel perforated sheets are widely used across industries such as construction, manufacturing, and decoration, where surface quality directly impacts their performance. During the production process, burrs are a common issue. While burrs on the back of the perforated sheet, if not sharp enough to cause injury, are typically not a concern and the product is still considered qualified, significant burrs can affect the sheet’s appearance and durability. So, what causes burrs on stainless steel perforated sheets? Here are some common factors:
 
1. Worn Punches
Stainless steel perforated sheets are produced by punching holes of various sizes using custom punches on CNC punching machines. These punches are typically made of alloy materials, which wear down over time due to continuous use. If a punch becomes significantly worn and is still used, it may produce large burrs. Therefore, regular punch replacement is essential for maintaining product quality.
 
Preventive Measures:
 
Regularly inspect and replace punches.
 
Use high-quality, durable punch materials.
 
Establish a maintenance schedule to ensure optimal working condition of the equipment.
 
2. Technician Issues
The production of stainless steel perforated sheets involves mold changes and punch installations, all of which are carried out by skilled technicians. The technical skills of operators can vary, and lower-skilled workers may improperly install the molds, leading to burr formation on the perforated sheets. Additionally, some technicians may intentionally perform excessive grinding, which can also result in burrs.
 
Preventive Measures:
 
Strengthen training for operators to ensure they are familiar with equipment operation and maintenance.
 
Strictly follow operational procedures to avoid improper adjustments and operations.

3. Equipment Issues
Over time, the wear of punch heads increases, and the gap between punch heads may become too large, resulting in many burrs on the back of the stainless steel perforated sheet. As equipment ages, its precision decreases, affecting production quality. Therefore, regular equipment inspection and calibration are crucial.
 
Preventive Measures:
 
Perform regular equipment inspections and calibration.
 
Replace worn-out equipment parts promptly to maintain precision.
 
Adjust equipment parameters according to production needs to minimize errors.
 
4. Environmental Factors
During the use of stainless steel perforated sheets, environmental factors can also lead to burr formation. For example, exposure to moisture or corrosive environments can cause oxidation or corrosion on the stainless steel surface, resulting in large burrs. This issue is more prominent in high-humidity or chemically active environments.
 
Preventive Measures:
 
Store and use stainless steel perforated sheets in appropriate environments.
 
Apply protective coatings to the stainless steel surface to prevent corrosion.
 
Use anti-corrosion coatings or other protective measures to enhance the sheet’s durability.
 
Conclusion
The formation of burrs on stainless steel perforated sheets is a common production issue that can result from punch wear, technician errors, equipment problems, and environmental factors. To prevent these problems, companies should regularly inspect and maintain their equipment, enhance operator training, and implement effective preventive measures based on actual conditions. By improving production processes and strengthening quality control, burr formation can be significantly reduced, leading to better product quality and a longer service life for stainless steel perforated sheets.
