The vehicle knife is usually based on two kinds of materials, one is hard alloy and one is high speed steel. These two kinds of car knives are different from different materials, and the selection of the sand wheel is different. The high speed steel is also dipped in water when it is grinding the knife. But these two knives have something in common.
Mostly still want to connect more,!! Every day, the knife, after a few months, you open the groove, natural is in the right,! Remember, sharpen the knife, must take the car to the workpiece, see where need to improve!! Ask some teachers,

Just a car knife. But sharpening is tricky, and pay attention to the following points: No matter which side of the sharpener, be sure to keep the Angle of the cut (such as the front Angle, the back corner, etc.). In order to make every face of a car knife look like a face, it must slowly move the blade of the tool when it is grinding. In order to observe the grinding of the blade, the blade is always at the top. To check the shape of the cylinder and the side of the wheel before the opening, the R Angle should not be too large (the grinding wheel or replacement when necessary). When opening a slot, the tip of the knife should be pointed upward, so that the hand should be moved on a straight line, and the hand can be found on the grinder, so that the hand will not be shaken. In the initial slot, you should select the back of the blade head to move the order of the blade, and check the condition of the blade. Use a template to avoid Angle.
