What is stainless steel burr?
Burrs are residual or extremely fine microscopic metal particles on the metal surface of stainless steel processing, milling or electroplating processes. The appearance of burrs will greatly reduce the quality standard of stainless steel workpieces. Therefore, corresponding deburring equipment and effective technology should be used to remove burrs on the surface of stainless steel.
What is the best way to deburr stainless steel
Stainless steel products are becoming more and more popular nowadays, but stainless steel materials inevitably cause burrs of different sizes during production and processing, so removing stainless steel burrs has become a difficult problem. Master the following 10 methods to say goodbye to stainless steel burrs!
1. Manual deburring:
Operators use files, sandpaper and other abrasives to polish the workpiece and remove burrs. For some customers who do not need to deburr a large number of products and pursue simplicity and cost-effectiveness, manual deburring tools are the most suitable.
If it is a special-shaped part, curved surface, spherical surface, pump body, and valve body, there are several methods:
2. Vibration Deburring
The method of removing burrs by vibration, sandblasting, and drum is widely used by enterprises. The problem with deburring by grinding is that sometimes the removal is not very clean and may require subsequent manual processing or other deburring methods. This method is suitable for small bulk products.
3. Freezing deburring
It mainly uses the characteristic that metal will become brittle after cooling. The surface of the burr becomes brittle after cooling, and then the burr is removed by ejecting projectiles. The application range is mainly stainless steel products with small workpieces and small wall thickness. Such freezing equipment has a high cost and is generally suitable for large-scale companies to invest in
4. Thermal explosion deburring
The "thermal explosion method" is also called the "thermal energy method". Its principle is as the name suggests. During the processing, flammable gas will be passed into the equipment furnace. After passing through some media and certain conditions, the gas will explode instantly, and the energy generated by the explosion will be used to destroy and remove the burrs. The cost of such "black technology" is naturally not low. Not only that, it is necessary to master the degree of explosion, which also requires higher technical requirements for operators.
5. Engraving machine deburring
The parts are engraved by CNC machine tools. The current cost of this engraving machine is generally within 5000-10,000 US dollars, or even cheaper. Applicable to some parts with regular deburring positions
6. Chemical deburring
Use the principle of electrochemical corrosion to perform fully automatic and selective deburring of metal parts. This method is mainly aimed at internal burrs that are difficult to remove by ordinary methods, such as burrs of about 5-7 wires in products such as pump bodies and valve bodies
7. Electrolytic deburring
Electrolytic deburring (ECD) is one of the most efficient deburring processes currently, and it only takes a few seconds to tens of seconds. The principle is to use the electrolytic effect, place the cathode near the burr, align the conductive part with the edge of the burr, and then connect the direct current to make the burr produce anode dissolution, thereby achieving the removal effect.
This method is suitable for removing more hidden positions in the workpiece, such as cross holes and some parts with complex shapes, such as gears, connecting rods, valve bodies, crankshaft oil holes, and some sharp corners and chamfers. The key point is that this method will have side effects. The corrosiveness of the electrolyte will affect the surface gloss of the workpiece near the burr, and even the dimensional accuracy. Therefore, after deburring, it is necessary to clean and rust-proof.
8. High-pressure water jet deburring
This is a method of removing burrs and flash using the instantaneous impact of water, which can achieve the purpose of cleaning. This equipment is very expensive and is mainly used in the core of automobiles and hydraulic control systems of engineering machinery.
9. Ultrasonic deburring
The propagation of ultrasonic waves can also generate instantaneous pressure, which can be used to remove burrs on stainless steel products. This method has high precision and is mainly used to remove microscopic burrs that can only be observed through a microscope.
If it is a relatively regular, flat, or gear-shaped stainless steel product, it can be done with our deburring machine!
10. Automatic deburring
whether it is used for wide belt to remove longitudinal burrs from large areas of stainless steel, using disc brushes and sand blocks to grind sharp edges, or using universal deburring brushes for flexible grinding to obtain uniform rounding and non-directional textures, and optional scotch brite and brushed effects, all can be done with non-woven brushes with variable speed control

In summary, there are many ways to remove stainless steel burrs. Which method to choose depends on the specific production requirements, part characteristics and available resources. In actual operation, it is often necessary to comprehensively consider these factors to determine the most suitable deburring method
