Nowadays, we all know that as a special tool for circular sawing machines, alloy saw blades are not only related to the cutting cost, but also the basis for cutting the quality of the workpiece. Therefore, cemented carbide saw blades are very important to metal cutting enterprises. , How should the company effectively keep the saw blade sharp?
1. Corresponding model and equipment
Alloy saw blades have strict requirements. Different models correspond to different equipment. They cannot be matched at will. For example, a saw blade that cuts metal is used to cut wood. This is a very common mistake. Some laymen think that cutting metal It’s okay. It should be faster and sharper to cut wood! If the saw blade used on a metal circular saw is used to cut wood, the result will be tooth jamming and tooth chipping, the saw blade is consumed too much, and the cost is too high .
2. The grasp of the time to replace the saw blade
Cemented carbide saw blades are consumables and have a service life. Many companies believe that during cutting, if the service life is not reached, they will not be replaced and will not be used until they are used! It is true, this is what all companies are doing One thing, I think it is normal and reasonable, but I don’t know that this is a very lazy approach;
If a saw blade has a lifespan of 40 squares, it should be replaced when it reaches 20 squares. After a break, at least another 30 squares can be cut. People will be more energetic after resting. The product is the same!
3. Association with its equipment
The quality of metal circular sawing machine equipment will also affect the quality of the saw blade. The coordination and compatibility between them are very important. If the best saw blade is placed on very poor quality equipment, its efficiency will be at least half discounted. the above.
The equipment should not be used to cut materials beyond the range. This will not only affect the performance and stability of the equipment, but the biggest damage is the carbide saw blade. Similarly, the equipment should have a reasonable rest period, which can also drive the saw blade to adjust its breath. time.
Saw blade sharpening is a very common thing in work, but many people often don't know when to sharpen it. In fact, there is time to choose. The following editor will tell you when it is better to sharpen it.
First, judging from the wood surface after sawing, if the surface of the wood board cut by a new saw blade is smoother, there is no obvious fuzzing, up and down saw dislocation, once these problems occur and no longer disappear, they must be polished in time;
The second is to judge according to the sawing sound. Generally speaking, the sawing sound of a new saw blade is clearer, while the sound of the saw blade should be dull when the saw blade should be sharpened;
The third is to judge according to the working power of the machine. When the saw blade should be sharpened, the working current of the machine increases due to the increase in load;
The fourth is to determine how long after sawing and grinding according to management experience.
