how to select the section shape of cemented carbide rotary file？
The section shape of the carbide rotary file cutter shall be selected according to the shape of the part to be filed, so that the shapes of the two can adapt. When filing the internal are surface, choose a half round file or a round file (small diameter workpiece); Triangle file shall be selected when filing internal corner surface; Flat file or square file can be selected when filing internal right angle surface. When using flat file to file the inner right angle surface, pay attention to making the narrow side (smooth edge) of the file without teeth close to one side of the inner right angle, so as not to damage the right angle surface. Selection of file tooth thickness
The thickness of file teeth shall be selected according to the allowance size, processing accuracy and material properties of the workpiece. Rough teeth file is suitable for machining workpieces with large allowance, low dimensional accuracy, large form and position tolerance, large surface roughness value and soft materials; On the contrary, the fine tooth file should be selected. When used, it shall be selected according to the machining allowance, dimensional accuracy and surface roughness required by the workpiece. Selection of dimension and specification of alloy file
The size and specification of cemented carbide rotary file shall be selected according to the size and machining allowance of the workpiece to be machined. When the processing size is large and the margin is large, the file with large size should be selected, otherwise, the file with small size should be selected. Selection of file teeth
The tooth pattern of tungsten steel grinding head file shall be selected according to the nature of the workpiece material to be filed. When filing aluminum, copper, mild steel and other soft material workpieces, it is best to use a single tooth (milling) file. Single tooth file has large front angle, small wedge angle, large chip holding groove, hard chip blockage and sharp cutting edge.
Cemented carbide rotary file, also known as cemented carbide high-speed assorted milling cutter, cemented carbide die milling cutter, etc., is used together with high-speed electric mill or pneumatic tools. Can finish all kinds of metal mold cavity; Clean the flash, burrs and welds of castings, forgings and weldments; Chamfering, rounding, groove and keyway processing of various mechanical parts; Polishing of impeller flow passage; Clean the pipeline; Finish machining the inner hole surface of mechanical parts; All kinds of metal and non-metallic carving, etc. It has been widely used in developed countries, and is an important means to improve production efficiency and realize bench worker mechanization. In recent years, this kind of tool has been gradually popularized and applied in China. With the increasing number of users, it will become a necessary tool for fitters and repairmen.
What are the precautions before using the rotary file
1. Before operation, please read Use the speed to select the appropriate speed range (please refer to the recommended starting speed conditions). Low speed will affect product life and surface processing effect, while low speed will affect chip removal, mechanical vibration and premature wear of products.
2. Select appropriate shape, diameter and tooth profile for different machining.
3. Select the appropriate electric mill with stable performance.
4. The exposed length of the shank clamped in the collet shall be 10mm at most. (Except for the extension handle, the speed varies)
5. Before use, idle the rotary file to ensure good concentricity. Eccentricity and vibration will cause premature wear and workpiece damage.
6. Too much pressure should not be used when using, because too much pressure will reduce the service life and efficiency of tools.
7. Check that the workpiece and the electric mill are clamped correctly and tightly before use.
8. Wear appropriate safety glasses when using.
[Improper operation method of carbide rotary file]
1. The speed exceeds the maximum speed range.
2. The operating speed is too low.
3. Use the rotary file in the groove and gap.
4. The pressure and temperature of the rotary file are too high, which causes the welding part to fall off.
