Milling cutter should be how to mill, can effectively use the milling cutter, and let the workpiece to achieve the required gloss?
To see what kind of cutter, decreased forefoot can make the cutting knife labor, but the decrease of strength and breaking knife, to reach the surface if required can be appropriately increased after angle, but also to control the feed and speed, no instance is clear
To sharpen the kitchen knife, use a blunt kitchen knife. Let it soak in salt water for 20 minutes, then grind, and then pour water. It is easy to grind, sharpen, and prolong the service life of kitchen knives. The glass products in the kitchen (especially light bulb), often black oil smoke, is not easy to wash. Use cloth dipped in some warm vinegar wipe, or coated with a layer of lime water in the glass to wipe dry, wipe with a cloth. Note that the bulbs should be taken down to wipe, wipe dry through after use with a kitchen knife as an example, the sake of convenience, we put the blade on both sides of the given definition: hold a knife, a thumb contact inside edge surface, the other side is the outer blade surface. A knife, the preparatory work before: 1.1, the first observation of blade: blade towards the eyes, flank and sight into about 30 degrees. You'll see an arc on the edge of the blade - a white line indicating that the knife is blunt. 1.2, prepare sharpening stone: be sure to prepare a piece of exquisite sharpening stone. If the edges of the blade are large, prepare a quick, coarse whetstone for quick sharpening. If there is no fixed knife stand, you can find a thick cloth (towels) pad under the grindstone. Put some water on the grindstone. Two, start sharpening (take the edge of the blade as an example): 2.1, grinding the inner blade first. The knife and the grindstone was 3 degrees to 5 degrees (in the blade surface is small, when cutting more labor force). When sharpening, keep this angle almost unchanged. Each grinding dozens of times, according to the method of 1.1 to observe the blade until the blade line is very small. If you continue sharpening, it will crimp the blade and increase the blade line.
Tool grinding method 2008-01-13 20:40 tool (refers to the overall turning tool and welding tool) with blunt re grinding, grinding on the grinder. Alumina grinding wheels (white) for grinding high speed steel tools, carbide grinding wheels (green) for sharpening carbide cutters.
