First, how to buy the saw blade correctly?
1. Basic data: 1 machine spindle speed, 2 machined workpiece thickness and material, 3 blade saw outer diameter size and aperture (shaft diameter);
2. Selection basis: Calculated by the spindle rotation number and the outer diameter of the mating saw blade. Cutting speed: V=π×outer diameter D×number of revolutions N/60 (m/s) The reasonable cutting speed is generally 60-90 m/ second,
Specific recommendations:
Material cutting speed
Cork 60-90 (m / s)
Hardwood 50-70 (m / s)
Particleboard, plywood 60-80 (m / s)
The cutting speed is too large, the machine tool has large vibration, large noise, reduced saw blade stability, reduced processing quality, too small cutting speed, and reduced production efficiency. The same feed rate, the amount of cutting per tooth increases, affecting the quality of the machining and the life of the saw. Because the saw blade diameter D and the spindle rotational speed N are power functions, in practical applications, it is most economical to increase the rotational speed and reduce the saw blade diameter.
3, the price ratio:
As the saying goes: "It's not cheap, good goods are not cheap." It may be true for other goods, but it may not be true for tool tools; the key is matching. Many factors on the job site: such as equipment sawing objects, quality requirements, personnel quality, etc. Conduct a comprehensive assessment, rationally choose the best use of materials, just right, to save money, reduce costs, participate in industry competition. This depends on mastery of professional knowledge and understanding of similar product information.
Second, the correct use:
In order for the saw blade to perform at its best, it must be used in strict accordance with the specifications;
1. Saw blades of different specifications and uses have different cutter head angles and base forms, so try to use them according to their corresponding occasions;
2. The size and shape accuracy of the spindle and the clamp of the equipment have a great influence on the use effect. Check and adjust before installing the saw blade. In particular, the factors affecting the displacement and slippage caused by the clamping surface of the splint and the saw blade must be eliminated;
3, pay attention to the working condition of the saw blade at any time, abnormalities, such as vibration, hum, and the surface of the processing surface, must be stopped and adjusted in time, and repaired in time to maintain the peak profit;
4, the grinding saw blade must not change its original angle, to avoid partial hot flashing of the cutter head, it is best to professionally repair the grinding
5. The saw blades that are temporarily not used should be hung vertically, avoiding the flat lay for a long time, and should not be placed on the object stack. The cutter head should be protected from collision.
Precautions:
1. Carefully read the instruction manual of the cutting machine and the items on the package before use.
2. Select the type of saw blade according to the material to be cut, and check the saw blade for cracks, distortion, and tooth loss. Do not use if the saw blade is damaged.
3. When using, be sure to install the cutter blade cover protective cover and wear a mask or eye protection.
4. Before installing the saw blade, please check whether the spindle of the cutting machine is bouncing. When installing, tighten the saw blade with the flange and the nut. After installation, the center hole of the saw blade must be firmly fixed on the platform flange. When the gasket is installed, the gasket must be bought and the blade should be gently pushed by hand to confirm whether the rotation is eccentric.
5, after installing the alloy saw blade, it needs to be pre-rotated for one minute before use, and the cutting operation can be performed when the standby device enters the working state.
6, non-automatic cutting operations, you must gently cut the saw blade into the material in normal operation, it is forbidden to force hard push. It is forbidden to reverse, and it is forbidden to stop the saw blade in the middle of the object to be cut, otherwise the sawtooth will fall off and the saw body will be deformed, which is prone to danger.
7. When you hear abnormal sound during use, stop the operation and find the cause of the abnormality when you see abnormal shaking or uneven surface, and replace the saw blade in time.
8. Please wipe the anti-rust oil in time after cutting to prevent the saw blade from rusting due to not using it for a long time.
9. Hang the blade vertically on the dry tool holder to avoid the wet area. Do not place the saw blade on the ground, otherwise it will easily cause the saw blade to deform. Do not stack the multiple saw blades directly. They must be packaged at intervals to avoid collision of the serrations.
10. When the saw blade is not sharp, it should be ground again. If it is not ground in time, it will easily destroy the original angle of the sawtooth, affect the cutting precision and shorten the service life of the saw blade.
