What to pay attention to when using a half round file
Presumably everyone is familiar with files, which are very common tools. There are countless types of files, such as round files, square files, half-round files, etc. Next, let's understand what a half-round file is, and what should be paid attention to when using a half-round file?
The half-round file is a tool for micro-processing the surface of metal and wood. A file is a hand tool with a strip shape and multiple blades. It is mainly used for microprocessing of metal, wood, leather and other surfaces.
The common types are: straight flat file, pointed flat file, triangular file, semi-circular file, round file, square file, diamond-shaped file, uniform triangular file, single-grain mill file, oily file, semi-circular aluminum file, Aluminum flat file, double-hole aluminum flat file, agricultural sickle file, narrow triangular file, extra narrow single-grain triangular file, pointed wooden file, flat wooden file, round wooden file, semicircular wooden file, horseshoe file, fish back file, Knife files, chain saw files, diamond assorted files, assorted files.
What to pay attention to when using a half round file
1. Be careful not to apply too much force when using the semi-circular file, otherwise it will leave deep file marks on the surface. In addition, the filing direction should always be kept parallel, which can be all along the front and rear directions, or can be inclined or along the up and down directions. In short, a flat surface should be produced by filing;
2. In order to eliminate the half-round file marks, use a flat file for the second file. If the surface of the putty is relatively flat at first, you can start with a flat file. The grinder grinds the plane, and after the putty surface is filed, it is further polished with a "straight-line" or "reciprocating" pneumatic grinder. The sandpaper used is generally 60 wells in size;
3. When grinding, it should be noted that the working surface of the grinding head should be kept parallel to the putty surface. Do not apply too much force when grinding. The grinder should be gently pressed and grinded by rotating force. If too much force is applied, a flat surface cannot be formed.
Half-round files can be used for micro-processing the surface of metal and wood. After reading the above introduction, I believe everyone already knows what to pay attention to when using half-round files.
