    What are the methods for deburring machine to remove metal burrs?


    1: Manual deburring


    The process in which the operator uses files, sandpaper, grinding heads and other tools to grind the workpiece and remove burrs. This method does not have very high technical requirements for workers, and is suitable for products with small burrs and simple product structures. Therefore, it is also a common method for removing burrs used by general enterprises. There are two types of files: manual files and pneumatic files. The cost of manual files is more expensive, the deburring efficiency is not very high, and it is difficult to remove complex cross holes.


    2: Die deburring   


    The burr is removed by the method of making a die and a punching machine. Deburring of the die requires a certain amount of production costs for the rough die and the fine die, and may also require the production of a shaping die. Suitable for products with simple parting surface, the efficiency and effect of deburring are better than manual methods.


    3: Grinding and deburring   


    Grinding and deburring is a method of removing burrs through vibration, sandblasting, rollers, etc., and it is also widely used by enterprises. The problem with grinding and deburring is that sometimes the removal is not very clean, and subsequent manual processing or other methods of deburring may be required. This method is suitable for small products with larger batches.


    4: Frozen deburring


    This is a method of using a sudden drop in temperature to make the burr brittle quickly, and then ejecting a projectile to remove the burr. Frozen deburring is suitable for products with small burr wall thickness and small workpieces. The price of the whole set of equipment is not low, about two to three million yuan.

    5: Deburring by thermal explosion


    Thermal explosion deburring is also called thermal energy deburring and explosive deburring. This is to pass some flammable gas into an equipment furnace, and then through the action of some media and conditions, make the gas instantly explode and use the energy generated by the explosion To dissolve the method of removing burrs. The equipment required for this method is expensive, usually reaching more than one million yuan, and the requirements for operation technology are also very high. The burr removal efficiency is low, and it can also cause side effects such as rust and deformation. Thermal explosion deburring is mainly used in some high-precision parts and components, such as precision parts such as automotive and aerospace.


    6: Engraving machine deburring 


    Use an engraving machine to remove burrs on the workpiece. The price of this set of equipment is not very expensive, usually only tens of thousands of yuan. It is suitable for removing burrs with simple spatial structure and simple and regular location.


    7: Chemical deburring 


    The chemical deburring method uses the principle of electrochemical reaction to automatically and selectively remove burrs on parts made of metal materials. It is suitable for those internal burrs that are difficult to remove, especially for removing small burrs on pump bodies, valve bodies and other products.


    8: Electrolytic deburring 


    A method of removing burrs on metal parts by electrolysis. This method will bring certain side effects, because the electrolyte is corrosive, the vicinity of the burr will also be electrolyzed, the surface will lose luster, and even affect the dimensional accuracy. Therefore, the workpiece should be cleaned and anti-rust treatment after electrolytic deburring. This method is suitable for removing burrs from cross holes in hidden parts or parts with complex shapes. The production efficiency is high, and an operation generally only takes a few seconds to tens of seconds. It is suitable for deburring of gears, connecting rods, valve bodies and crankshaft oil passages, as well as rounding of sharp corners, etc.


    9: Deburring by high-pressure water jet   


    This is a method of using the instantaneous impact of water to remove burrs and flashes, and at the same time achieve the purpose of cleaning. This set of equipment is expensive and is mainly used in the heart of automobiles and hydraulic control systems of construction machinery.


    10: Ultrasonic deburring 


    The propagation of ultrasonic waves can also generate instantaneous high pressure, which can be used to remove burrs on parts. This method has high accuracy and is mainly used to remove some microscopic burrs that can only be observed through a microscope.
