1, mechanical grinding
It is processed by a professional machine using a grinder.
2. Semi-mechanical grinding
Grind the blade with a grinding wheel. Because of the large wear, it is only suitable for rough grinding and then manual grinding.
Step 3 grind by hand
The cost is low, the effect is good, and the people who demand high skating quality are all hand skaters. Manual grinding of speed skating skates is generally flat grinding: fix the skates on the sharpener, put on gloves and carefully check whether the two knives are on the same plane. Rub it back and forth with a big grinding wheel several times to see if the wear marks are even. After confirmation, use a large grinding wheel (30CM in diameter) to push grinding in the shape of "8" until burrs appear on both sides of the blade, and then finish rough grinding. Then, continue the "8" grinding with coarse oilstone until the grinding trace is very small. Then use a fine oilstone to remove the burrs on the knife surface and side, and then polish a pair of shoes. Take off the skates and remove the dust and scum on the surface.
Expanding knowledge: blade standard for roller skates
How far the skates should be opened is a concern of many friends. In fact, the blades of skates are not specially marked. Generally, the thumb is floating to the left, and it is almost the same if you can't touch the most concave part, or you can see a depression.
Matters needing attention when cutting the edge of skates
1. You can choose to sharpen the knife manually, but if you are not a professional skater, it is not recommended to choose manual grinding, because it is difficult to grasp the grinding degree when sharpening the knife, and it is easy to wear the skates.
2. In order to prevent the blade from being damaged and reduce the service life of the skates, it is suggested that beginners and enthusiasts try to choose a professional mechanical mill when sharpening the knives.
3, grinding ice skates is a fine job, first smooth, and then ditch.
The blade of skates has two sides, inside and outside. Before grinding skates, it is necessary to see whether the inner edge and the outer edge are flat. If the inner edge is not lost, just go straight to the ditch.
Novices are afraid of falling and often touch the ice with their inner blades. After a long time, the inner edge is shallower than the outer edge. At this time, it is necessary to first make the inner and outer blades as high as the grinding wheel, and then use the grinding wheel to grind a groove between the inner and outer blades.
6. In order to ensure the smoothness of the blade surface of the skates, the eyes must follow the skates closely to avoid abrasion.
