What are the methods of deburring machine to deburr metal?

1: Manual deburring

The operator uses tools such as files, sandpaper, and grinding heads to polish the workpiece and remove burrs. This method does not require very high technical requirements for workers, and is suitable for products with small burrs and simple product structure. Therefore, it is also a commonly used deburring method in 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 intersecting holes.

2: Die deburring

The burr is removed by the method of making a die and a punch. Die deburring requires a certain amount of rough die and fine die making, and may also need to make a shaping die. It is suitable for products with simple parting surfaces, and the efficiency and effect of deburring are better than manual methods.

3: Grinding and deburring

Grinding and deburring is a method of removing burrs by means of vibration, sandblasting, rollers, etc., and is also widely used by enterprises at present. 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 large batches of small products.

4: Freeze deburring

This is a method of using a sudden temperature drop to quickly embrittle the burr, and then ejecting a projectile to remove the burr. Frozen deburring is suitable for products with small burr wall thickness and small workpieces.

5: Thermal deburring

Thermal deburring is also known as thermal deburring and explosion deburring. This is to introduce some flammable gas into an equipment furnace, and then through the action of some media and conditions, the gas will explode instantly, and the energy generated by the explosion will be 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 operating technology are also very high. The deburring efficiency is low, and it can also cause side effects such as rust and deformation. Thermal deburring is mainly used in some high-precision parts and components, such as automotive and aerospace precision parts.

6: Deburring of engraving machine

Use the engraving machine to remove the burr 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 positions.

7: Chemical deburring

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

8: Electrolytic deburring

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

9: High-pressure water jet deburring

This is a method of removing burrs and burrs by the instantaneous impact force of water, and at the same time, it can achieve the purpose of cleaning. This equipment is expensive, 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 pressures that can be used to deburr parts. This method has high precision and is mainly used to remove some microscopic burrs that can only be observed through a microscope.
