CNC machining of CNC parts to remove metal burrs
Metal casting, milling or electroplating will produce burrs, and there are residues or extremely fine microscopic metal particles on the surface of metal parts. The appearance of burrs will greatly reduce the quality standard of metal workpieces, so it should be avoided as much as possible, or some burrs should be removed. The simplest deburring method is as follows. The following CNC precision machining parts manufacturers will introduce to you.
1. Manual deburring
The operator uses a file, sandpaper, grinding head and other tools to grind the workpiece to remove the burr. This method does not have high technical requirements for workers, and is suitable for products with small burrs and simple product structure. Therefore, it is also a deburring method commonly used by enterprises. There are two types of files: manual files and pneumatic files. Manual files are more expensive, the deburring efficiency is not very high, and complex cross holes are difficult to remove.
2. Die Deburring
The burr is removed by making a die and punch. The deburring of the mold requires a certain manufacturing cost for both the rough mold and the fine mold, and a forming mold may also be required. It is suitable for products with simpler parting surfaces, and the efficiency and effect of deburring are better than manual methods.

4. Freeze deburring
This is a method of using a sudden drop in temperature to make the burr quickly embrittle, and then spraying projectiles to remove the burr. Freeze deburring is suitable for products with smaller burr wall thicknesses and smaller workpieces. The price of the whole set of equipment is not low, about 2.3 million yuan.
5. Thermal deburring
Thermal deburring is also known as thermal deburring and explosion deburring. This is to introduce some easily occurring gas into the equipment furnace, and then make the gas explode instantly through the action of certain media and conditions, and use the energy generated by the explosion to dissolve and remove the burrs. The equipment required for this method is expensive, usually reaching more than 10,000 yuan, and the requirements for operating technology are also very high. Inefficient deburring can lead to side effects such as rusting and deformation. Thermal explosion deburring is mainly used for some high-precision parts, such as automobile, aerospace and other precision parts.
6. Deburring by engraving machine
The burr on the workpiece is removed by the engraving machine. The equipment is not very expensive, generally only tens of thousands of yuan. It is suitable for removing burrs with simple spatial structure and simple and regular locations.
7. Chemical deburring
Chemical deburring is a process of automatically and selectively removing burrs on metal parts using the principle of electrochemical reaction. It is suitable for hard-to-remove internal burrs, especially for removing small burrs on products such as pump bodies and valve bodies.
8. Electrolytic Deburring
A method for electrolytic deburring of CNC machining parts. This method will bring certain side effects, because the electrolyte is corrosive, the vicinity of the burr will be electrolyzed, the surface will lose its luster, and even the dimensional accuracy will be affected. Therefore, the workpiece should be cleaned and rust-proofed after electrolytic deburring. This method is suitable for removing burrs or complex-shaped burrs in hidden holes of parts. The production efficiency is high, and one operation usually only takes a few seconds to tens of seconds. Ideal for deburring gears, connecting rods, valve bodies, and crankshaft oil line orifices, as well as rounding sharp corners.

3. Grinding and deburring
Grinding and deburring is a method of removing burrs by means of vibration, sandblasting, rollers, etc., and is currently widely used by enterprises. The problem with grinding and deburring is that sometimes the removal is not very clean, and subsequent manual processing or other deburring may be required. This method is suitable for large batches of small products.
4. Freeze deburring
This is a method of using a sudden drop in temperature to make the burr quickly embrittle, and then spraying projectiles to remove the burr. Freeze deburring is suitable for products with smaller burr wall thicknesses and smaller workpieces. The price of the whole set of equipment is not low, about 2.3 million yuan.
