June 01 13:42 2021

Manual deburring

Generally, the most commonly used method for small factories is to use files, sandpaper, and grinding heads as basic tools. Among them, the files include manual files and pneumatic files.

Remarks: The labor cost is high, the efficiency is low, and it is difficult to remove the special-shaped hole. Scope of application: The technical requirements of workers are not high, the applicable burrs are small, and the structure of the parts is complicated.

Die deburring

Using a die, use the die to deburr in the punch.

Remarks: If you need a die (rough die + fine die), you may need to add a set of shaping die. Scope of application: It is suitable for workpieces with more complicated parting surfaces, and the efficiency and deburring effect are better than those of manual work.

Grinding and deburring

There are many methods for grinding and deburring, and the most common ones include: shaking, sandblasting, rollers and other methods.

Remarks: There are drawbacks of removing impurities, and some need to manually dispose of remaining burrs or other methods to remove burrs. Scope of application: suitable for small pieces with larger batches.

Frozen deburring

Use cooling to make the surface of the burr brittle, and then use the spray shot to remove the burr.

Remarks: The equipment is about two or three hundred thousand, which is not available for all companies; scope of application: suitable for products with small burr wall thickness and small workpieces.
Thermal explosion deburring

Or it is called thermal deburring or blasting deburring. Pass some flammable gas into the equipment furnace, and then pass through some media and conditions to make the gas blast instantly, and use the energy from the blasting to dissolve and remove burrs.

Remarks: The equipment is very expensive (millions), the operators have high technical requirements, low efficiency, and side effects (rust and deformation); application scope: used in some high-precision parts, such as precision parts such as cars and spacecraft .

Engraving machine deburring

The equipment is not very expensive (tens of thousands), and the scope of application: it is suitable for complex space structures and complex and regular deburring parts.

Chemical deburring

Using electrochemical principles, the parts made of metal materials are automatically and selectively deburred.

Remarks: Suitable for internal burrs that are difficult to remove, suitable for large burrs on pump bodies, valve bodies and other workpieces (thickness less than 7 wires).

Electrolytic deburring

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

Remarks: The electrolyte is corrosive, and the parts around the burrs are also electrolyzed. The surface will lose the original luster, which will affect the accuracy of the scale. After deburring, the workpiece should be cleaned and treated with rust prevention.

Scope of application: It is suitable for removing burrs from cross holes in hidden parts of parts or parts with messy shapes. The efficiency is high, and the deburring 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.

High-pressure water spray to remove burrs

Using water as the medium, use its instant impact to remove burrs and flashes after processing, as well as a cleaning effect.

Remarks: The equipment is expensive, most of which are used in the heart of cars and hydraulic control systems of engineering machines.

Ultrasonic deburring

Ultrasonic uses instant high pressure to remove burrs.

Remarks: For some microscopic burrs, if the burrs need to be checked by a microscope, you can try to remove them by ultrasonic method.
