Metal deburring is a very important process step in the field of metal processing. In the processing of metal parts, due to various reasons, such as cutting, grinding, turning, etc., will produce some burrs on the metal surface. These burrs not only affect the appearance of metal parts, but also have a negative impact on their performance. Therefore, the removal of metal burrs is a key link to ensure the quality of metal parts.
First, the method of metal deburring
1. Mechanical deburring: mechanical deburring is the use of mechanical force on the metal burr removal method. Common mechanical deburring methods include sandpaper grinding, polishing, filing and so on. This method is suitable for the shape is relatively simple, not high requirements of metal parts deburring.
2. Chemical deburring: chemical deburring is the use of chemical reactions, so that the metal burr in a chemical solution reaction, so as to achieve the purpose of removing the burr. This method is suitable for some of the higher surface quality requirements of metal parts deburring.
3. Electrochemical deburring: electrochemical deburring is the use of electrochemical reaction principle, under the action of the current to remove metal burrs. This method has the advantages of fast deburring speed, good results, applicable to complex shapes, high requirements of metal parts deburring.
4. Laser deburring: laser deburring is the use of laser high energy instantaneous action on the metal burr, so that it melts, evaporation, so as to achieve the purpose of removing the burr. This method has the advantages of fast speed, high precision, small impact on the metal surface, but the cost of equipment is higher.
5. Ultrasonic deburring: ultrasonic deburring is the use of ultrasonic high-frequency vibration, so that the metal burr fatigue cracks under the action of ultrasonic waves, so as to achieve the purpose of removing the burr. This method has a good deburring effect, small impact on the metal surface and other advantages.
Second, the attention of metal deburring
1. choose the appropriate deburring method: according to the shape of the metal parts, size, requirements and other factors, choose the appropriate deburring method, in order to achieve the best deburring effect.
2. pay attention to the temperature and pressure in the deburring process: in the deburring process, pay attention to the control of temperature and pressure to avoid deformation or damage to the metal parts.
3. regular inspection of deburring equipment: deburring equipment in the use of the process of wear and tear, damage and so on, regular inspection of equipment to ensure its normal operation.
4. do a good job after deburring treatment: deburring, metal parts should be cleaned, dried and other processing to remove residual burrs, oil, etc., to ensure the cleanliness of metal parts.
5. Quality testing: after deburring, the quality of the metal parts should be tested to ensure that they meet the requirements for use.
In short, metal deburring is an indispensable process step in the field of metal processing. Only by doing a good job of deburring can we ensure the quality and performance of metal parts. In the actual production process, according to the characteristics of the metal parts, choose the appropriate deburring method, and pay attention to the deburring process parameters control, to ensure that the deburring effect. At the same time, we also need to do a good job after deburring to ensure the cleanliness and quality of metal parts.
