F0402(Steel File-Square)



1. Classification: round files, half-round files, square files, flat files, triangle files, wooden files, diamond files, knife files, etc.

2. Material: T12 steel

Due to the high carbon content of T12 steel, there are more excess carbides after quenching. According to the wear resistance and hardness, it is suitable for production without impact load and cutting speed.

Tools that are not high and the cutting edge does not heat up, such as files (greater than 62HRC), etc.

(3) Common specifications: 6 inches, 8 inches, 10 inches and 12 inches

(4) File use: used to file metal plates, metal gangs or plastic plates, etc.

(5) Little common sense

According to the file pattern, it can be divided into single-grain files and double-grain files. The teeth of single-grain files are inclined at an angle to the axis, which is suitable for processing soft non-ferrous metals;

The main and secondary file patterns of the double-grain file are arranged crosswise, used for processing steel and non-ferrous metals, and the filing is relatively brisk

According to the number of main file lines per 10 mm length, it is divided into No. -, among which is coarse tooth file, is middle tooth file, is fine tooth file, and

is a polished file, used for roughing and finishing respectively

(6) Diamond files are generally made of 45# steel. Diamond files have no file lines, but are electroplated with a layer of diamond powder on the surface for filing hardened metals.

(7) Matters needing attention

Files should not be used to file hardening materials; files should not be placed on top of each other; files should not be used too fast, otherwise it will be prematurely worn; fine-tooth files are not allowed to file soft metals; new files should not file hard metals; mixed files should not be used too hard to avoid breaking bend

Note: Quenching refers to a metal heat treatment process in which the metal is heated to an appropriate temperature and maintained for a period of time, and then immersed in a quenching medium for rapid cooling. Commonly used quenching media are brine, water, mineral oil, air and so on. Quenching can improve the hardness and wear resistance of metal workpieces, so the quenched material is generally harder, which will greatly reduce the service life of the file
