How to sharpen tools

In order for the work to be done qualitatively and not to require significant physical effort, it is important to monitor the status of all tools. First of all, you need to monitor their grinding, which is carried out with the help of tools such as a bar, grindstone, grindstone and file.

Sharpening tool

This tool is designed to sharpen the blade of cutting tools. Different kinds of grinders and grain are produced. Using coarse grinding leads to the fact that scratches and notches remain on the sharpened tools. Fine-grained grinders are removed, making the blade smooth and sharp. When sharpening the chisel, chisel, plane with the help of a round grindstone, it is directed towards the blade. When working, it is important to monitor the position of the point. It should lie completely on the grindstone. When sharpening, in order to avoid annealing the tool steel, the stone should be regularly wetted with water. After the point has been sharpened, it needs to be slightly rounded in order to avoid the appearance of chipping on the machined surfaces when working with the tool.

Sharpening of axes is carried out on a round sharpener. The chamfer of the tool is pressed against the sharpener and when sharpened, make sure that the angle of sharpening does not change. In this case, the middle of the ax handle is held with one hand, and the instrument's arm is with the other. The sharpener should be directed towards the ax. From time to time, the ax and the grindstone must be cooled with water. Sharpening the ax is carried out on both sides. The blade is driven in a circular motion on a fine-grained bar or a bundle.

Tool bar

A bar made from sandstone is used for rough sharpening of tool blades. He quickly removes metal because of large grains. Before sharpening, the bar, like the grindstone, is wetted, and then fixed. Then press the tool to the bar and, pushing, drive it forward and backward. After sharpening the block, the blade is brought to the knife.

Tool tool

The tool is designed for grinding the blade after sharpening. In addition, it is used to remove burr tools from the blades. On lubricated with engine oil or water soaked, the blade is driven by a blade, circulating and turning the blade alternately one or the other side until it becomes absolutely smooth and does not get a brilliant mirror surface.

File tool

There are several types of files used for sharpening various tools. For example, a trihedral file is intended for sharpening a saw. The size of the file in this case is determined by the size of the saw teeth. Before the beginning of sharpening, the saw's teeth are bred in order to have the same height and the same width of the divorce. This is done either with tie pincers or with a special tool( wiring).

Before grinding, the saw is clamped in a vice so that the teeth protrude about 20 mm above the jaws of the vice. Saw the saw on the right side of the canvas towards the left. At the same time on its teeth appear increasing the cutting ability of the tool burrs. When sharpening it is necessary to make sure that all the teeth have the same number of file movements. Before sawing raw wood, the saw teeth are sharpened on both sides. Correctly and carefully sharpened drills help to obtain accurate and qualitative holes. As a rule, a drill is sharpened by a specialist with the necessary knowledge and experience. To this end, he uses files or files, and final refinement performs on the assortment.

Intended metal drills are sharpened on corundum or emery brusks and round grinders. In the event that the drill bit is slightly blunted, it must be sharpened with a small notched knife file. This is done by light movements in the direction counter-clockwise.

Sharpening of the scissor blades is carried out at an angle of 70-74 °.In order to significantly reduce the friction of the blades on the blades, an equal 2-3 ° back angle is made. To extend the life of all cutting tools, they should be stored in a place protected from dust and moisture. Now you know how to sharpen tools - an ax, a saw, a knife, blades of cutting tools.
