As someone who frequently works with metal fabrication, I know that deburring methods play a crucial role in ensuring smooth, finished edges on parts. In this article, I’ll introduce 10 simple deburring techniques that are easy to implement, regardless of your experience level. I’ll also recommend some reliable machines that can streamline the process and improve efficiency. Whether you’re working on small-scale projects or large production runs, these methods and machines will help you achieve clean, professional results with minimal effort.

Metalworking industry can not avoid the use of آلات اللكم, whether it is cost-effective mechanical آلة اللكمs, or more intelligent and fine pneumatic punching machines, the emergence of burrs or chamfers are difficult to avoid. And burrs, chamfering these small workpiece problems on the impact of product quality is often not to be underestimated, today we summarized some of the advice and methods shared by teachers, hoping to help you process a better workpiece.

10 kinds of simple deburring way

1.Manual deburring: the way adopted by the universal enterprise, the use of files, sandpaper, grinding head as an auxiliary tool to smooth the burr. Among them, the file is divided into manual file and pneumatic file.

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

2.Die deburring: Using the production of punching die with punching machine for deburring.

Features: It requires a certain amount of punching die (rough die + fine die) production cost, and may also need to make shaping die. It is suitable for products with simple parting surface, and the efficiency and deburring effect is better than manual.

3.Grinding deburring: grinding includes vibration, sandblasting, roller and other methods, currently more companies use.

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

4.Freezing deburring: Using cooling to make the burr quickly brittle, and then spraying projectiles to remove the burr.

Features: the price of the equipment is about two or three hundred thousand, suitable for the burr wall thickness is small and the product is also small products.

5.Thermal explosion deburring: also called thermal deburring, explosive deburring. Through some flammable gas, into a device furnace, and then through the role of some media and conditions, so that the gas instantly explode, using the energy generated by the explosion to dissolve the burr removal.

Features: expensive equipment (millions of prices), high operating technology requirements, low efficiency, side effects (rust, deformation); mainly used in the field of some high-precision parts, such as automotive aerospace and other precision parts.

6.Engraving machine deburring: the use of engraving machines to remove burrs

Features: the price of equipment is not very expensive, about tens of thousands of yuan, suitable for simple space structure, the required deburring position simple and regular.

7.Chemical deburring: The principle of electrochemical reaction is used to automatically and selectively complete deburring operations on parts made of metal materials.

Features: suitable for difficult to remove the internal burr, suitable for the pump body, valve body and other products with small burrs (thickness less than 7 silk).

8.Electrolytic deburring: an electrolytic processing method that uses electrolysis to remove burrs from metal parts.

Features: electrolytic solution has a certain corrosive, parts burr near the electrolytic effect, the surface will lose its original luster, and even affect the dimensional accuracy, the workpiece should be cleaned and rust-proof treatment after deburring. Electrolytic deburring is suitable for removing burrs from hidden parts of cross holes or parts with complex shapes, with high productivity and deburring time generally only a few seconds to tens of seconds. Suitable for deburring gears, connecting rods, valve bodies and crankshaft oil circuit orifices, as well as chamfering sharp corners.

9.High-pressure water jet deburring: using water as the medium, using its instantaneous impact to remove burrs and flying edges produced after processing, and at the same time can achieve the purpose of cleaning.

Features: expensive equipment, mainly used in the heart of the car and the hydraulic control system of construction machinery.

10.Ultrasonic deburring: Using ultrasonic waves to generate instant high pressure to remove burrs.

Features: mainly for some microscopic burrs, generally if the burr needs to be observed with a microscope, you can try to remove it with ultrasonic methods.

In addition to the above several simple deburring methods, the following also recommended several deburring faster and more convenient deburring machine.

The first: power tool deburring machine, this small tool can be directly on the board to remove the burr, and cutting edge without oxidation, similar to such a small tool 30 °, 45 °, 60 ° angle of inclination can be used, but also for bending the edge.

The second: all-round equipment of deburring and chamfering compound machine, it can deburr, chamfering, surface drawing, metal surface treatment at one time.

The third: some small tools for deburring and chamfering, which can be used in single or small batch production.
