教大家一个简单实用的开刃方法。因为YG6X硬质合金钢硬度非常大,即使是钝了,刀口也不会有太大磨损,不需要重新磨整个刀角,只需要简单的开下刃就好。1.在平整的台面上铺一张1000目以上的水磨砂纸(有条件的可以用2000目的金刚石磨盘,更方便),如图所示,刀口平贴砂纸(如果按不平,开出来的刀刃会倾斜),刀身与台面呈30°左右(刀角是15°)。2.食指按住刀头,保持角度,均匀用力往后拖动。注意只能往后拖动,不能往前磨,因为刀口太薄,
Teach you a simple and practical tooling method. Because YG6X hard alloy steel hardness is very large, even if the blunt, the blade will not have too much wear and tear, do not need to re-grind the entire corner, just a simple open lower edge like. 1. On the flat surface of a shop more than 1,000 heads of water sanding paper (conditional can use 2000 purpose diamond disc, more convenient), as shown in the figure, the edge of flat sandpaper (if the uneven, out of the knife will be Tilt), blade and table was about 30 ° (angle is 15 °). 2. Index finger hold the blade to maintain the angle, even forced to drag backwards. Note that only drag back, can not forward grinding, because the blade is too thin,
