Deburring machine What are the methods for removing metal burrs?

1: Manual deburring

Operators use files, sandpaper, grinding and other tools to polish the workpiece and remove burrs. This method is not very high technical requirements for workers, suitable for small burrs, simple product structure of the product, so it is also the general enterprise commonly used to remove burrs method. File is divided into manual file and pneumatic file two kinds. The cost of manual file is more expensive, the deburring efficiency is not very high, and it is difficult to remove complex cross holes.

2: die deburring

The burrs were removed by making a die and a press. Die deburring requires a certain amount of rough die and fine die production costs, may also need to produce plastic die. It is suitable for products with simple parting surface, and the efficiency and effect of deburring are better than that of manual method.

3: Grinding deburring

Grinding deburring is a method to remove burrs by vibration, sandblasting, roller, etc., which is also widely used by enterprises. The problem with abrasive deburring is that sometimes the removal is not very clean and may require subsequent manual treatment or other methods of deburring. This method is suitable for large batches of small products.

4: frozen deburring

This is a method that uses a sudden drop in temperature to rapidly embrittle burrs, and then jetts projectiles to remove burrs. Frozen deburring is suitable for products with smaller burr wall thickness and smaller workpieces, and the price of the whole set of equipment is not low, about two or three hundred thousand yuan.

5: Hot explosion deburring

Thermal explosion deburring is also known as thermal deburring, explosive deburring, which is to pass some easy gas into a equipment furnace, and then through the action of some media and conditions, the gas explodes instantly, and the energy generated by the explosion is used to dissolve and remove burrs. The equipment required by this method is expensive, usually reaching more than one million yuan, and the requirements for operation technology are also high. Burr removal efficiency is low, but also cause rust, deformation and other side effects. Thermal explosion deburring is mainly used in some high-precision parts, such as automotive aerospace and other precision parts.

6: Engraving machine deburring

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

7: Chemical deburring

Chemical deburring method is a process of automatically and selectively removing burrs from parts made of metal materials by using the principle of electrochemical reaction. It is suitable for those internal burrs that are difficult to remove, especially for removing small burrs on the pump body, valve body and other products.

8: electrolytic deburring

Method of removing burrs from metal parts by electrolysis. This method will bring certain side effects, because the electrolyte is corrosive, the electrolysis near the burr will also be affected, the surface will lose luster, and even affect the dimensional accuracy. Therefore, the workpiece should be cleaned and treated with rust prevention after electrolytic deburring. This method is suitable for removing cross-holes or burrs of complex parts in hidden parts, with high production efficiency, and an operation generally takes only a few seconds to tens of seconds. Suitable for deburring gear, connecting rod, valve body and crankshaft orifice, as well as chamfering of sharp corners.

9: high-pressure water jet deburring

This is the use of water instantaneous impact to remove burrs and flash methods, while achieving the purpose of cleaning. The cost of this equipment is not cheap, mainly used in the heart of the car and the hydraulic control system of construction machinery.

10: Ultrasonic deburring

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