Files can be used in different versions for different purposes. Nail files are multi-bladed tools that are used for the machining of materials. Editing with a file is one of the oldest manual production methods. When the people in the early Middle Ages in the location were warm transform metals and to modify the properties of the substances, the files got a very important meaning in the metalworking. The work procedure for filing has not changed since then. The feed motion is generated manually via the file and transferred to a tightly stretched piece of work. The first file had only a small number of different attached cutting, which were carved by hand into a metal plate. The cutting edges are called teeth or even blows in a file.
These teeth are today geometrically. The metal plate sitting on the teeth, called a file handle. This booklet is a tapering files Angel. It handles are made of wood or plastic can later be attached. Today, files are made exclusively by machine.
The machine cut files here most often are used. The chip is diverted here raspelnd or even schabend. Milled files, however, cutting removing chips from the workpiece. The installation of the file teeth on the files page called blow. Distinction in the RASP of cut, the cut up and the cross cut. Shredding files have very large individual teeth, which distributes broad on the handle are. They are suitable only for the processing of wood, leather and plastics. Single-cut files have many parallel-mounted teeth. The result is a sudden edit of the workpiece. For this reason, this file is used only to edit from soft metals and plastics. Cross cut files are the teeth of the lower Woosh carved files, in which the upper cut diagonal crosses. They are suitable for the machining of hard materials. Also soft materials can be processed with cross bat files. However, the low voltage room admits only little material removal here. Also the number of teeth per inch can vary with a file handle. In jargon called the cut number. The file is the finer the cut number is greater. Files with the bat number 1-3 are known as Schruppfeilen. You can wear off quite a few chips. However, the surfaces exhibit no good texture. Files with the bat 4-6 are known as Schlichtfeilen. The chip removal is much lower, the surfaces, however, have a much better quality. Clean with a wire brush can just in fine Schlichtfeilen not always lead to the desired success. For this reason, each series be small plates to remove stuck chips. The surface quality can be improved also when filing through the application of chalk on the file handle. The chalk settles into the cutting room of the cutting edge and thus prevents deep penetration of the cutter into the workpiece. The size of the file folders can vary also greatly. Especially small files are called here key or needle files. Larger files are referred to as arm files. The form of the file folders is standardised, as also the cutting. The most commonly used file is a flat file. It is suitable for manipulating flat surfaces. In addition, there is still round, half round, knives, sword – and triangle files. Due to the large number of filing forms can be transmitted virtually any shape on a workpiece. Bernhard Hess
