1, artificial deburring

This is also a common way for general enterprises to use files, sandpaper and grinding heads as auxiliary tools. Files include manual files and pneumatic misoperation.

Brief comments:

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 structure.

2, mold deburring

Deburring is carried out by making a die with a punch.

Brief comments:

It needs a certain manufacturing cost of stamping die (rough die+fine die), and may also need to make forming die.

It is suitable for products with simple parting surface and has better efficiency and deburring effect than manual operation.

3. Grinding and deburring

This deburring method includes vibration, sand blasting, rolling and so on, which is widely used in enterprises at present.

Brief comments:

There is a problem that the removal is not very clean, and it may be necessary to manually handle the residual burr or cooperate with other methods to deburr.

Suitable for large quantities of small products.

4. Freezing and deburring

Burrs become brittle quickly by cooling, and then they are sprayed to remove them.

Brief comments:

The equipment price is about 200,000 to 300,000 yuan;

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

5, thermal explosion deburring

Also known as thermal deburring and explosive deburring. By introducing some reactive gases into the equipment furnace, and then under 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.

Brief comments:

Expensive equipment (millions of dollars), high technical requirements for operation, low efficiency and large side effects (rust and deformation);

It is mainly used in some fields of high-precision parts, such as automotive aerospace and other precision parts.

6, engraving machine deburring

Brief comments:

The equipment price is not very expensive (tens of thousands), which is suitable for occasions with simple spatial structure and simple and regular deburring position.

7, chemical deburring

Based on the principle of electrochemical reaction, the parts made of metal materials are automatically and selectively deburred.

Brief comments:

Suitable for internal burrs that are difficult to remove, and small burrs (thickness less than 7 wires) of products such as pump body and valve body.

8, electrolytic deburring

An electrolytic machining method for removing burrs from metal parts by electrolysis.

Brief comments:

Electrolyte is corrosive, and parts will be electrolyzed near burrs, so the surface will lose its original luster and even affect the dimensional accuracy. After deburring, the workpiece should be cleaned and rustproof.

Electrolytic deburring is suitable for deburring hidden parts or parts with complex shapes, with high production efficiency, and the deburring time usually takes only a few seconds to dozens of seconds.

Suitable for deburring and chamfering gears, connecting rods, valve bodies and crankshaft oil circuits.

9, high pressure water jet deburring

Using water as the medium, the burr and flash produced after machining are removed by its instantaneous impact force, and the purpose of cleaning is achieved at the same time.

Brief comments:

This equipment is expensive, and it is mainly used in the hydraulic control system of automobile heart and construction machinery.

10, ultrasonic deburring

Ultrasonic waves generate instantaneous high pressure to remove burrs.

Brief comments:

Mainly for some microscopic burrs, generally, if it is necessary to observe burrs with a microscope, they can be removed by ultrasonic method.
