Four steps blades grinding tactics:
Advice 1:“Blade by adjusting the wheels”
This is the first step in the relative position of the forest and the sandwheel. It is certainly not easy to grind. The “blade mouth” here is the main cutting blade, and “flattening” means that the main cutting blade of the shredding part of the blade is a horizontal position. “Wheel” refers to the surface of the sand wheel. “Reduing” slowly means closer. Currently, the exercise cannot be exposed to the wheel.
Tips 2: “Drilling axis placed in the front corner”
Tips 2: “Drilling axis placed in the front corner”This refers to the relationship between the axis of rhinestones and the surface of the wheel. The “front angle” is half the upper angle of 118 ± 5 °. The diagonal angle of horizontal blade. It is necessary to remind students that triangular cards of 60 °, 60 ° and 90 ° commonly used in students must be recalled, and students are easy to master.Formula 1 and tactics refer to the relative position in front of the drilling head blade.Do not ignore the diagonal angle in order to adjust the blade, or ignore the mouth of the flat blade in order to put the oblique placement axis. These errors are often made in real operation. Currently, the exercise is ready to contact the wheel when the position is correct.
Tips 3: “From the blade to the back to the back”
This means that the mouth of the forest blade began to slowly grind the blade over the entire surface of the rear knife. This is practical for the dissipation of heat and the grinding of blades. Based on the stable 1 and 2 consolidation formula, the drilling head can gently contact the wheels and make a small amount of blade grinding. Forest cooling. When the blade climbs after cooling, it is necessary to continue to define the position of tactics 1 and two.
Win 4: “Do not look at the tail of the upper and lower swing”
This action is also very important during the grinding of the borehole blade. At the same time, the tail of the drilling head cannot be tilted above the midwife of the sandwheel, otherwise it will make the blade blunt and cannot be cut.
