Scope of Application and Usage of Tube Brush

Tube brushes generally refer to test tube brushes. Test tube brushes, also known as tube brushes, straw brushes, hole cleaning brushes, twist wire brushes, pipe brushes, etc., are a very widely used brush product. The tube brush is mainly made of iron wire (steel wire) as a skeleton, with many fine filaments that are neatly arranged and stretched outwards. The tube brush is mainly used to remove the tiny burrs on the surface of the hole after finishing, so as to improve the smoothness of the inner hole, generally from a small to a large level.

1. Where is the scope of application of the tube brush?

As a new type of brush product, the tube brush has a wide range of applications. It is often used for deburring of groove edges in hydraulic valve holes, deburring of cross holes, deburring of air conditioners and refrigerators (compressors), deburring of cylinder blocks, and deburring of engine parts. Fittings, machining, in-hole processing, brake hub processing; tube brushes are also suitable for polishing some conical, conical and venturi-shaped holes. The spherical brush can easily and quickly carry out the optimal surface treatment of various shapes and sizes of cylinders, valves, lumens, and pipes. The polishing brush can be automatically centered and automatically calibrated to perform fine and consistent processing on the surface of the hole, without affecting the original precision and size of the workpiece, and is convenient, safe, economical and effective.

Tube brushes also have indelible credits in medicine or pipes. Tube brushes can clean both sides and tops of pipes, even if they are deep, because the new tube brushes with tails have been vacated.

2. How to use the tube brush?

The pipe can be processed by swiping it on a bench drill or vertical drill with a suitable stroke, or on a lathe or a horizontal grinder. When processing bulky and large workpieces, it can be stuck on a pneumatic drill or a hand electric drill. The speed can be selected within 50-100 rpm depending on the size of the workpiece. The speed of moving up and down is about 30 times/min, and generally 8 to 10 times of reciprocation is enough. Deburring and polishing tool brushes should be carried out while turning or moving the processing part. It is best to use light lubricating oils, not solvents, when machining. It should not be used in high temperature, dry, and high speed situations. The diameter of the deburring and polishing tool brush is generally 5%-15% larger than the diameter of the machined hole.

3. Precautions for using the tube brush

1. Tube brushes of different materials should be selected according to the condition of the workpiece, such as throwing metal tube grooves, steel wire test tube brushes or copper wire test tube brushes can be used. 2. When using the tube brush, the pressure should not be too large. If the pressure is too high, the thin lines on both sides will be distorted or overheated, which will cause the thin lines to break, melt quickly, and reduce the service life.
