1.Manual deburring

This is also a common enterprise method, using file, sandpaper, grinding head as auxiliary tools. The file has artificial file and pneumatic stagger.

Brief comment: The labor cost is more expensive, the efficiency is not very high, and it is difficult to remove the complicated cross holes. The technical requirements for workers are not very high, and it is suitable for products with small burrs and simple product structure.

2.Punching die deburring

Deburring with a punching die and a punch

Brief comment: A certain amount of die (rough die + fine die) production fee is required, and a shaping die may also be required. It is suitable for products with simple parting surface, and the efficiency and deburring effect are better than manual.

3.Grinding and deburring

This type of deburring includes vibration, sand blasting, rollers, etc., which are currently used by enterprises.

Brief comment: There is a problem that the removal is not very clean, and it may be necessary to manually process residual burrs or cooperate with other methods to deburr. Suitable for small products with larger batches.

4.Freeze to deburr

The burrs are quickly embrittlement by cooling, and then the burrs are removed by spraying the projectile.

Brief comment: The equipment price is about two to three million yuan;

Suitable for products with small burr wall thickness and small products.

5.Hot burst deburring

Also called heat deburring, explosion deburring. By passing some natural gas into an equipment furnace, and then through the action of some media and conditions, the gas burst in an instant, using the energy generated by the explosion to dissolve and remove burrs.

Brief comment: The equipment is expensive (prices of millions of dollars), the operation technology requires high, the efficiency is low, and the side effects (rust, deformation); mainly used in some high-precision parts and components, such as precision parts such as automotive and aerospace.

6.The engraving machine deburrs

Comment: The price of the equipment is not very expensive (tens of thousands), and it is suitable for simple space structure and simple and regular deburring positions.

7.Chemical deburring

Using the principle of electrochemical reaction, the deburring operation is automatically and selectively completed on parts made of metal materials.

Brief comment: It is suitable for internal burrs that are difficult to remove, and suitable for small burrs (thickness less than 7 threads) in pump bodies and valve bodies.

8.Electrolytic deburring

An electrolytic machining method that uses electrolysis to remove burrs on metal parts.

Brief comment: The electrolyte is corrosive, and the parts near the burrs are also subjected to electrolysis. The surface will lose its original luster and even affect the dimensional accuracy. After deburring, the workpiece should be cleaned and anti-rust treatment.

Electrolytic deburring is suitable for removing burrs from cross holes in hidden parts or parts with complex shapes. The production efficiency is high. The deburring time generally only takes a few seconds to tens of seconds. Suitable for deburring of gears, connecting rods, valve bodies and crankshaft oil passages, as well as rounding of sharp corners.

9.High-pressure water jet deburring

Using water as the medium, use its instantaneous impact to remove burrs and flashes generated after processing, while achieving the purpose of cleaning.

Brief comment: The equipment is expensive, mainly used in the heart of automobiles and the hydraulic control system of construction machinery.

10.Ultrasonic deburring

Ultrasound generates instantaneous high pressure to remove burrs.

Brief comment: mainly for some microscopic burrs, generally if the burrs need to be observed with a microscope, you can try to remove them by ultrasonic.
