1. Manual deburring
This is also the way commonly used by general enterprises, using files, sandpaper, grinding and so on as auxiliary tools. Files have manual files and pneumatic displacements.
Brief comment: The labor cost is more 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 the products with small burrs and simple product structure are suitable.
2. Deburring the die
The deburring was carried out by making a die and punching machine.
Brief comment: Need a certain die (rough die + fine die) production costs, may also need to produce plastic die. Suitable for simple parting surface products, efficiency and deburring effect is better than manual.
3. Grind and deburr
This kind of deburring includes vibration, sandblasting, roller and other methods, which are currently used by enterprises.
Brief comment: There is a problem that the removal is not very clean, which may require subsequent manual treatment of residual burrs or other methods of deburring. Suitable for large batch of small products.
4. Remove burrs by freezing
Cooling is used to rapidly embrittlement burrs, which are then removed by spraying projectiles.
Brief comments: The price of the equipment is about two or three hundred thousand;
Suitable for products with smaller burr wall thickness and smaller product.
5, hot explosion to remove burrs
Also known as thermal deburring, explosive deburring. By passing some easy gas into an 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.
Brief comments: The equipment is expensive (millions of prices), the operation technology requires high, low efficiency, side effects (rust, deformation); Mainly used in some high-precision parts, such as automotive aerospace and other precision parts.
6, engraving machine deburring
Brief comment: The price of the equipment is not very expensive (tens of thousands), it is suitable for simple spatial structure, and the required deburring position is simple and regular.
7. Chemical deburring
On the principle of electrochemical reaction, the deburring of parts made of metal materials can be completed automatically and selectively.
Brief comments: Suitable for internal burrs that are difficult to remove, suitable for pump body, valve body and other products small burrs (thickness less than 7 wires).
8, electrolytic deburring
An electrolytic machining method for removing burrs from metal parts by electrolysis.
Brief comment: The electrolyte has a certain corrosion, the vicinity of the parts burr is also subject to electrolysis, the surface will lose the original luster, and even affect the dimensional accuracy, the workpiece should be cleaned and anti-rust treatment after deburring.
Electrolytic deburring is suitable for removing the burr of concealed parts or complicated parts, with high production efficiency, and the deburring time is generally 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
With water as the medium, the instantaneous impact force is used to remove the burrs and flash produced after processing, and the purpose of cleaning can be achieved.
Brief comment: The equipment is expensive, mainly used in the heart of the car and the hydraulic control system of construction machinery.
10, ultrasonic deburring
Ultrasound produces instantaneous high pressure removal of burrs.
Brief comment: Mainly for some microscopic burrs, generally if the burrs need to be observed with a microscope, you can try to use ultrasonic methods to remove.
