How to test cemented carbide rotary burr for grinding and chamfering

Published On: September 23, 2020

Tungsten Carbide Rotary burrs are used for forming and cutting all around the world. they are also Tungsten carbide rotary files are used worldwide for forming and cutting. They are also used to remove sharp edges. Workers use these rotary files for different drilling tasks. It is important to obtain high-quality burrs to perform tasks correctly. Many offline and online companies offer high-quality burr at a price tag.

General rotating surface (inner and outer circle) can be divided into centering grinding and centerless grinding according to the method of clamping and driving the workpiece; according to the relationship between feed direction and machined surface, it can be divided into longitudinal feed grinding and transverse feed grinding; considering the position of grinding wheel relative to the workpiece after grinding stroke, it can be divided into through grinding and fixed range grinding; according to the type of grinding wheel working surface, it can be divided into peripheral grinding and end grinding Face mill and peripheral end mill.


How to test tungsten carbide rotating burr?

Tungsten carbide rotary file sets can be used in a variety of materials. These materials include cast iron, titanium, steel, cobalt, aluminum, gold, silver, platinum, nickel, glass fiber, copper, plastic, bronze, wood, zinc, etc. Various cutting methods of cemented carbide burr are ideal for some specific materials. When these burrs are applied to soft metals, they do not crack at all.

Tungsten carbide rotary burr companies must properly test these burrs before selling them. Each burr has to go through various tests. If it passes all tests effectively, it is sent to the distribution section. If you want to know how to test these burrs,  then no problem! We will explain it in detail.


1. Grinding test

company’s workers take away carbide rotary files and then carry out grinding tests. Workers first use these burrs to grind hard materials. When these burrs do a good job of grinding hard materials, workers begin to grind soft materials. If these burrs break or break soft material,  y are not easy to use. In case they grind soft material effectively, use burrs for another test.

2. Cutting test

Workers use carbide rotary files to cut hard and soft materials.  they mark lines one by one on a variety of materials and cut them open. If this set of burrs is competent to cut each material,  then they can be considered for cutting.

3. Sharp edge test


In the sharp edge test, these burrs are used to remove sharp edges from different materials.  se materials include wood, steel, cobalt, aluminum, etc. these burrs shall remove sharp edges and smooth surface of the material. If they can pass the test, burrs are excellent in every way.   workers will send them to the distribution area.

Try to make the tool contact the workpiece as much as possible because more cutting edges can penetrate into workpiece, and the processing effect can be better; finally, avoid part of the file handle contacting the workpiece, because it will overheat the file and damage or even destroy the brazed joint.

Buy carbide burrs

Our carbide burrs which manufacture are machine ground from a specially chosen grade of carbide. Due to the extreme hardness of the tungsten carbide, they can be used on much more demanding jobs than HSS (High-Speed Steel). Carbide Burrs also perform better at higher temperatures than HSS, so you can run them hotter, and for longer. HSS burrs will start to soften at higher temperatures, so carbide is always a better choice for long-term performance.
