Rotary files include tungsten carbide rotary files, which are made of high-quality tungsten carbide materials, also known as tungsten steel rotary files; high-speed alloy steel rotary files, which are made of high-quality high-speed alloy steel materials. They are usually used in conjunction with high-speed electric grinders or pneumatic tools. They can be used for a variety of operating needs, such as processing cast iron, cast steel, carbon steel, alloy steel, stainless steel, hardened steel, copper and aluminum. So, what types of rotary files are there?
1. Shape classification
Generally, rotary files can be divided into the above 19 shapes. The most commonly used ones are cylindrical, spherical, flame head, etc. In China, letters such as A, B, and C are often used to directly represent each shape, while letters such as ZYA, KUD, and RBF are usually used for abbreviations abroad.
2. Blade tooth classification
Usually, single-edged toothed rotary files are more suitable for processing soft non-ferrous metals, plastics, soft high-tensile steel or hard wood, while cross-tooth patterns are more suitable for high cutting performance on hard materials, such as workpiece grinding operations made of cast iron, cast steel, and fiberglass plastic materials.
Each shape of rotary file can choose the tooth shape of the blade according to specific operation requirements. Generally, the international standard tooth shape can refer to the above six types. Among them, each tooth shape is suitable for:
1. Tooth pattern for aluminum
Especially suitable for soft metals such as aluminum alloys, brass, and magnesium. Due to its wide tooth spacing, it is conducive to rapid removal of cutting.
2. Coarse tooth pattern
Soft materials such as bronze, tin, zinc, pure copper and other easy-to-process materials are recommended.
3. Medium tooth pattern/standard tooth pattern
Applicable to the processing of various steels (including tempered steel), cast steel and almost all metal materials. This tooth shape has excellent surface processing quality and relatively high processing efficiency.
4. Diamond tooth pattern
This tooth shape is suitable for the processing of high-alloy steel, stainless steel, magnesium alloy, gray cast iron and zirconium-nickel steel, and effectively avoids the adverse phenomenon caused by chip crushing during operation.
5. Close tooth pattern
Applicable to processing operations with high surface quality requirements such as finishing, especially tempered steel with Rockwell hardness (HRC) below 66.
6. Cross tooth pattern
This tooth shape is suitable for various metal materials (including tempered steel and corrosion-resistant materials), with less vibration during processing and easy to control operation.
