10 points to choose the right rotary file
Rotary files are manual tools used for metalworking, mainly for finishing and processing various metal materials. Here are some key points to consider when selecting a rotary file for different metal materials:
Material Identification |
| First, identify the type of metal material to be processed, such as cast iron, cast steel, carbon steel, alloy steel, stainless steel, copper, aluminum, et |
| Hardness Consideration |
| Choose a rotary file based on the hardness of the metal. Tungsten carbide rotary files can process various metals with a hardness of HRC70 or less, including hardened steel. |
| File Shape |
| Select a rotary file that is compatible with the shape of the part being processed. For example, choose a half-round or round file for internal circular arcs, and a flat or square file for internal right-angle surfaces. |
| Tooth Pattern Selection |
Choose different tooth patterns based on the properties of the material. For instance, single-tooth pattern files are suitable for soft materials like aluminum, copper, and soft steel. |
| File Size |
| Choose the size of the rotary file based on the size of the workpiece and the amount of material to be removed. Larger workpieces or larger stock removal requires larger-sized rotary files. |
| Tooth Coarseness |
Coarse tooth files are suitable for workpieces with large material removal and low precision requirements; fine tooth files are suitable for workpieces with small material removal and high precision requirements. |
Operating Speed
Choose the appropriate operating speed according to the diameter of the rotary file and the material being processed. For example, a 3mm diameter rotary file has a recommended starting speed of 65,000 RPM, while a 16mm diameter file has a recommended starting speed of 15,000 RPM.
Matching Tools
Rotary files are generally used with high-speed electric grinding machines or pneumatic tools and can also be mounted on machine tools. Consider compatibility with existing tools when selecting.
Brand and Quality
Choose rotary files from well-known brands and those with a good reputation to ensure quality and durability.
Coating Selection
Some rotary files have coatings, such as titanium nitride or aluminum titanium nitride, which can improve anti-stick characteristics and extend tool life.
By considering these points, you can select the appropriate rotary file for different metalworking needs to achieve the best processing results.
