| Carbide rotary file is also called carbide high-speed milling tool or carbide mold milling tool. In comparatively developed countries abroad, such files have long been applied in wide fields and regarded as an important means to raise the production efficiency and realize the mechanization in bench work. In recent years, this kind of cutting tools has been gradually popularized for application with increasing users in our country and will become a necessary tool for fitters and repairmen.
The main characteristics of the carbide rotary file are as follows:
>> It can be used to machine various metal (including all kinds of quenching steels) and nonmetal materials (such as marble, jade and bone) with hardness of the machined work piece<HRC70;
>> Replace small grinding wheel with shank for a majority of work without dust contamination; .
>> Giving good machining quality and high smoothness, it can be used to process mold cavities of various forms with high accuracy;
>> Enjoying a long service life, it is ten times the high-speed steel cutter and more than 200 times the small grinding wheel in durability;
>> It is easy to grasp and operate, safe and reliable. It can reduce labor intensity and improve working condition;
>> With high economic benefit, it may have 10 times reduction in cost of comprehensive process. Generally, the carbide rotary file is driven by a hand electric or pneumatic tool (can also be used on machine tools). Usually, the rotary speed of an electric or pneumatic tool is between 6,000~50,000 rpm.
The file must be correctly clamped during operation. To avoid repeated advance of too, the cutting mode of reverse milling is preferred. Wear protective spectacles to prevent flying cutting bits during operation.
