During the machining process, burrs are everywhere. No matter how advanced and precise equipment you use, it will always be born with the product, burrs on mechanical parts. Some are caused by plastic deformation during the cutting process; some are flashes from casting, die forging and other processing, and some are residual materials extruded from welding. The existence of burrs will have adverse effects on many aspects such as the machining accuracy, assembly accuracy, reprocessing positioning and appearance quality of the parts.
1. Manual deburring
This is also a method commonly used by general enterprises, using files, sandpaper, grinding heads, etc. as auxiliary tools. The files have manual filing and pneumatic shifting.
Brief comment: The labor cost is expensive, the efficiency is not very high, and it is difficult to remove complex cross holes. The technical requirements for workers are not very high, and it is suitable for products with small burrs and simple product structures.
2. Grinding and deburring
This type of deburring includes vibration, sandblasting, roller and other methods, which are currently used by many companies.
Brief comment: There is a problem that the removal is not very clean, and it may be necessary to manually deal with the remaining burrs or use other methods to remove burrs. Suitable for small products with larger batches.
3. Dry ice cleaning machine deburring
Through the low-temperature blasting characteristics of dry ice, plastic burrs can be instantly shed.
Brief comment: The price of dry ice cleaning equipment is about RMB 20,000 to RMB 30,000; it is suitable for removing burrs from various plastics.
4. Chemical deburring
Using the principle of electrochemical reaction, parts made of metal materials can be automatically and selectively deburred.
Brief comment: It is suitable for internal burrs that are difficult to remove, and is suitable for small burrs (thickness less than 7 wires) on pump bodies, valve bodies and other products.
5. High-pressure water jet deburring
Using water as a medium, its instantaneous impact force can be used to remove burrs and flash generated after processing, and at the same time achieve the purpose of cleaning.
Brief comment: The equipment is expensive and is mainly used in the heart of automobiles and hydraulic control systems of construction machinery.
