Tungsten Carbide Burrs (Finished) Manual of Tungsten Carbide Burrs Tungsten carbide burrs are mainly used for cutting and processing all kinds of metal work-pieces and polishing welded metal parts as well as non-metallic handicrafts like marbles, jades, and bones, and also for medical surgical cutting equipment. As a necessary tool for bench workers and repairmen, its advantages are good cutting quality, smooth finish of work pieces and long tool service lifetime, which ensures better production efficiency and economic benefits in comparison to similar products. It can be used to process all kinds of metal materials, and to clear off scraps, welded seams and burrs of casting parts, forging parts and welded parts. And also can be used to cut quenched steel with the hardness lower than HRC70. It can be used to process internal hole’s surface, chamfer angles, radius and grooves of mechanical accessories. It can be used to replace small shanked grinding disc to ensure processing without dust pollution, which can improve efficiency three to five times. Its abrasion resistance is ten times better than that of high speed steel knife, more than one hundred times better than that of small grinding disc. Tungsten carbide burrs are mainly driven by manual wind-driven tool and electric tool, and can also be applied to machine tools. They must be tightly clamped at correct position when they are being used. Tungsten carbide burrs have good performance only under high speed operating state. Its operating speed should be between 3800-7500 surface cm per minute. The matched rotary speed between burrs and main shaft is recommended as follows:
Diameter (mm) of Burrs Recommended Main Shaft Speed (r/min) Ø3~5 40000~50000 Ø6~7 30000~35000 Ø8~9 25000~28000

Burrs Shape Selection Select shape which conforms to your workpiece. Maximize the area of contact between the tool and material. Having more of the cutting edge engaged in the material will improve the part finish. Cutting Style Selection The choice of flute cut style is dependent on the type of material being machined, the amount of stock removal, and the finish required. In general, the harder the material being machines, the finer the cut should be. It is also essential that adequate power and operating speed of the drive is used to ensure optimum performance and tool life, machine collets must be absolutely concentric to avoid chipping, and any tool runout will result in chatter and premature wear. Suitable lubricants (grease, paraffin, chalk, etc.) can be used to ease loading problems when machining soft materials.
The double cut fluting style can be used almost universally, and allows for rapid stock removal when machining the harder materials. This chisel tooth pattern not only minimizes tool chatter, but also reduces the chip to a granular shape in most materials, thereby reducing or eliminating the sharp sliver chips are normally experienced. This chip reduction also helps to eliminate loading of the flutes. An improvement in tool control will be realized as the Double Cut tends to reduce the pulling action of the main flute pattern; operator fatigue is also lessened. Although some finish reduction may be experienced, improvement in material removal (and, therefore, increased production) will be realized. Burrs (Chinese Standard) Cylinder Cylinder End Cut
