How to Effectively Avoid Scratches in Sheet Metal Machining?

With the rapid development of the sheet metal industry, sheet metal is now involved in all walks of life, such as steel plates, stainless steel plates, aluminum plates, aluminum profiles, alloy materials, angle steels, channel steels, square passes, pipes, copper and so on. They all can be conducted by professional sheet metal machining in order to better ensure product quality, which is essential for effective control of product scratches.


Ⅰ. Scratches during sheet metal machining by fitter


1. Keep the drill bit sharp when drilling and tapping sheet metal.


2. Keep the work surface clean when drilling and tapping.


3. The placement method must be separated by layers, and it is strictly forbidden for the workpieces to contact each other.


4. For aluminum profile workpieces, special transfer devices should be used as far as possible or plastic frames should be placed in EPE isolation.


Ⅱ. Scratches during the transfer of professional sheet metal machining materials


1. When the delivery personnel use a hand-push forklift or elevator to transfer, they must be tied up with PE plastic wrap before transferring.


2. During the transfer process, try to keep the pallet in balance, and do not tilt the pallet too much to prevent the material from moving and scratching the workpiece.


Ⅲ. Scratches in the assembly process of sheet metal machining products


1. Keep the work surface clean during work.


2. Wear cotton gloves plus disposable gloves and sleeves when working to prevent sweat and oil stains from soiling the surface.


3. Gently hold and release, without dragging or pulling.


4. When the defective product is repaired, it must be protected according to the good product protection method to prevent secondary defects.


Ⅳ. Scratches during sheet metal machining at the surface


1. Before loading materials of professional sheet metal fabrication, the workpiece should be carefully inspected to remove defects, and the scratched materials should be repaired in time.


2. Wear gloves and sleeves during operation to prevent sweat and oil stains from soiling the surface.


3. Pre-treatment. During the processing, the workpiece and the workpiece, the workpiece and the iron frame should be prevented from contacting each other, and the PVC glue stick should be used for isolation, or the hanging method should be used for sheet metal machining.


4. When unloading, you must pay attention to the decoupling method to avoid scratching the workpiece.


5. The finished product shall be protected, packaged and placed in accordance with regulations, and shall not be stored in the sheet metal machining workshop for more than four hours to prevent the workshop air from corroding the workpiece.
