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 round 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 task 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 centring grinding and centerless grinding according to method of clamping and driving workpiece; according to  relationship between  feed direction and  machined surface, it can be divided into longitudinal feed grinding and transverse feed grinding; considering  position of grinding wheel relative to  workpiece after grinding stroke, it can be divided into through grinding and fixed range grinding; according to  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 set 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 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 file 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 file 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 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 material. If they can pass test, burrs are excellent in every way.   workers will send them to distribution area.

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