1. Appearance and size
Pay attention to whether the tooth profile, number of teeth and size of the saw blade meet the requirements of the order, and carefully observe whether there are nicks, burrs, incomplete tooth profile, blunt teeth, and rough surface, so as to lay the foundation for its use and grasp the timing of sharpening.
2. Saw blade tension test
Install the newly purchased saw blade on the sawing machine and start the sawing machine to move it. If there is undue vibration, swing or whistling sound, the saw blade quality is unqualified.
1. Installation saw blade
Measure the outer diameter of the saw blade and the center hole, select the centering washer, install the saw blade on the saw blade seat, and then lock it with the knurled nut of the saw blade seat, then loosen the saw blade seat locking screw, and then move the saw blade Seat, align the outer diameter of the saw blade with the corresponding scale of the saw blade seat, and then tighten the screw. If the saw blade has broken teeth or when new teeth are made, the grinding guide must be used. Generally speaking, it is easier to grind with the grinding guide, and the grinding guide should be used whenever possible.
2. Rotating tight adjustment of circular saw blade
If the rotation of the saw blade is not properly tightened, the forward displacement of the saw blade will be inaccurate at this time. Therefore, after the saw blade is installed, rotate the circular saw blade counterclockwise with your left hand and try the tightening of the rotation. If the tightening is not appropriate, use M17 open-end wrench adjusts the anti-loosening nut to make the saw blade rotate properly.
The principle of tightness is to eliminate the inertia of the saw blade rotation and the impact of the grinding wheel, not too tight.
3. Saw blade thickness adjustment
In order to make the grinding of the saw teeth even up and down, the center of the grinding wheel and the thickness center of the saw blade should be in a straight line.
4. Cutting angle adjustment
Since the material to be cut by the saw blade varies greatly, the appropriate cutting angle should be selected according to the material to be cut. Cut the angle, and then tighten the clamping seat screw.
5. Tooth shape transformation
Generally, there are two types of teeth, one is triangular teeth, and the other is curved teeth. The tooth type should be determined before grinding. To change the tooth profile when the machine is running, use the L-shaped wrench to change the tooth profile change button to select the tooth profile to be ground.
Saw blade grinding machine grinding starts
1. Tooth pitch and push jaw adjustment
Before starting the machine, pay attention to keep the distance between the grinding wheel and the saw blade at least 10mm, and then start the machine. Before adjusting the push, pay attention to keep the distance between the grinding wheel and the saw blade at least 10mm, then start the machine, adjust the push jaw stroke adjustment lever, and adjust the push jaw stroke , So that the landing point of the push claw is in a suitable position
2. Setting of tooth height difference
After the machine is started, if you grind the high and low teeth, adjust the high and low tooth difference adjustment lever, the indicator needle and scale will display After the machine starts, if you grind the high and low teeth, adjust the high and low tooth difference adjustment lever, the indicator needle and scale will display zero .
3. Grinding begins
After completing the above steps, the grinding wheel feed screw can be used to move the grinding wheel head toward the saw blade. When it is about to touch the saw blade, adjust the tooth adjustment screw to align the original tooth cavity of the saw blade with the grinding wheel (adjusting the screw to Twist clockwise to move the saw teeth forward, and the tooth back will be ground more, otherwise, the cutting angle will be ground more), and then move the grinding wheel head to the saw blade. If the grinding wheel does not grind to the bottom of the tooth when it advances, it has been grind to the back of the tooth when it moves back, which means it is not deep, on the contrary, it is too deep. At this time, use the tooth depth adjustment lever to adjust the tooth depth to the grinding wheel to lightly touch the bottom and back of the tooth. . The shape of the grinding wheel will be slightly deformed during grinding. If necessary, use the grinding wheel dressing stone to dress the grinding wheel. In principle, as long as the cutting angle is lightly ground, the backlash angle will be ground more.
