Tungsten carbide rotary burr is one of the small carbide tools employed in different industries such as machinery, automobiles, ships, chemicals, craft carving, and so on. They may also be used for deburring. If you’re a tungsten carbide rotary burr beginner, you may well be mistaken for countless forms of tungsten carbide rotary burrs. You may think what the right configuration of carbide rotary burrs to decide on, which one is much more suitable, and what should pay attention to. With this passage, there are 7 strategies for tungsten carbide rotary burrs beginners that will help you select the another beneficial.
You can study in the following aspects:
1. Shape
2. Size
3. Fitting
4. Direction
5. Grease
6. Pressure
7. Speed
1. Shape
There are several shapes of tungsten carbide rotary burrs. They are tungsten carbide cylindrical rotary burrs (A kind), tungsten carbide cylindrical rotary burrs (C type), tungsten carbide spherical burrs (D type), tungsten carbide oval burrs (E type), tungsten carbide arch round nose burrs (F type), tungsten carbide arch pointed nose burrs (G type), tungsten carbide flame burrs (H type), tungsten carbide 60°cone burrs (J type), tungsten carbide 90°burrs (K type), tungsten carbide conical round nose burrs (L type), tungsten carbide conical pointed nose burrs (M type), tungsten carbide inverted cone burrs (N type), and so on.
2. Size
A larger carbide head has higher efficiency. So, choosing a reasonable big head can increase work and save you time. The top diameter might be 3mm, 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, and so forth.
3. Fitting
Selecting the best chuck is essential for the tungsten carbide burrs beginner. Usually, 4 common forms of chuck/ holders will be used. They are hydraulic tool holders, multi-clamp tool holders, universal tool holders, and shrink-fit holders.
Hydraulic Tool Holders
A hydraulic tool holder is a tool-holding system suitable for most machining applications. The hydraulic tool chuck adopts a tool clamping method distinctive from conventional chucks. The force is created by a screw mechanism. By operating the screw mechanism, uniform hydraulic pressure might be generated in the chuck. This pressure is transmitted to an expanding steel sleeve that clamps the tool.
Multi-clamp Tool Holders
The structural style of the multi-clamp tool holder is extremely simple. The tool is firmly clamped in three positions using a ground polygonal hole. In high-speed cutting machining, multilateral clamping is a great tool clamping method, because the clamping with the tool is realized with the elastic deformation in the collect. The benefit of this tool holder is its very compact design.
Universal Tool Holders
Universal tool holders can be purchased in two styles. An example may be for light-duty machining and one is made for medium to heavy-duty machining. An essential benefit of the universal tool holder is that it has good vibration damping, which may improve tool life and workpiece surface finish quality, as well as costs are similar to most high-end socket tool holding systems.
Shrink Fit Holders
Shrink fit holders are based on the principle of thermal expansion and contraction, and adopt induction technology to heat the chuck. Shrink fit tool holders have several advantages, mainly including high radial runout accuracy, high transmission torque, and relatively small shape design. Regarding vibration-damping performance, shrink-fit chucks are inferior to hydraulic chucks and multi-clamp chucks.
With the chucks or holders, workers should also be careful. First of all, workers should better utilize correct chuck for corresponding burrs and view the concentricity from the machine to prevent tremors and shock. Otherwise, it’s going to cause premature wear. Then, the grabbing position needs to be at the very least 2/3 of the shank.
4. Direction
What the beginners should pay attention to is because they must move burr head one way, from left to right, or from directly to left. If you move it forwards and backwards, it may cause premature wear and cracks within the innovative.
5. Grease
When you are processing highly viscous materials you’d better use lubricating oil or grease in order to avoid carbide burr that doesn’t work, due to blockage of chip removal groove.
6. Pressure-use the right pressure
A suitable pressure ought to be used during work. Much underhand may cause the temperature to get way too high to dissipate. It might even cause the welding part to go away.
7. Speed
Even when you usually are not using tungsten carbide burrs, RPM is always a significant thing you must love. For tungsten carbide rotary burrs, reasonable operating speed is critical to offer the required level of cutting and workpiece quality.
Try and choose the highest speed within the allowable range, because low speed will reduce chip removal performance and produce trembling, which ends up in reduced tool life and poor surface finish.
Workers should select a suitable operating speed for each form of rotary carbide burr in line with the specific application. There are two methods, where you can look at to regulate speed into a suitable number.
Method 1
Increasing speed can improve processing quality and lengthen tool life, but it may cause the shank to break;
Method 2
Reducing speed will assist you to quickly remove material but can cause the system to overheat and cutting quality to fluctuate.
