The characteristics of the cemented carbide material itself determine the importance of the safe operation of the cemented carbide cutting machine blade. Please take protective measures before installing the blade to avoid unnecessary personal and property safety losses caused by the blade falling and hurting people.

1. Listening inspection: When installing the blade, please use your right index finger to carefully lift the blade and suspend the blade, then lightly tap the blade body with a wooden hammer, and listen to the sound from the blade body with your ears. It proves that the cutter body is often damaged by external force and there are cracks and damages. Such blades should be banned immediately. Dull cutting blades are prohibited!

2. Blade installation: Before installing the blade, please carefully clean the dust, chips and other sundries on the mounting surface of the rotating bearing of the cutting machine, and keep the bearing installation surface and the cutting machine clean.

2.1. Place the blade carefully and stably on the mounting surface of the bearing, and turn the bearing of the cutting machine by hand so that it is automatically centered and aligned with the center of the blade.

2.2. Install the pressure knife block on the blade of the cutting machine and align the bolt holes with the bolt holes on the bearing of the cutting machine.

2.3. Install the hexagon socket bolts, and tighten the screws with a hexagon wrench to securely install the blade on the bearing.

2.4. After the blade is installed, there must be no looseness or deflection.

3. Safety protection: After the blade is installed, the safety shield and other protective devices on the cutting machine must be installed in place and play a real protective role before starting the cutting machine (there should be safety baffles around the blade working room on the cutting machine , steel plate, rubber and other protective layers).

4. Running speed: The working speed of the cutting machine should be limited to below 4500 rpm. It is strictly forbidden to run the cutting machine at a speed exceeding the limit!

5. Test machine: After the blade is installed, run it empty for 5 minutes, and carefully observe and listen to the operation status of the cutting machine. Absolute looseness, vibration and other abnormal sounds are absolutely not allowed (such as the bearing of the cutting machine has obvious The axial and end runout) phenomenon exists. If any abnormal phenomenon occurs, stop the machine immediately and ask professional maintenance personnel to check the cause of the fault, and use it after confirming that the fault is completely eliminated.

6. During the cutting process, please advance the circuit board to be cut at a uniform speed, and avoid advancing the circuit board too rapidly. When the circuit board collides violently with the blade, it will cause damage to the blade (collision, cracking) and even serious safety accidents.

7. Blade storage method: It is strictly forbidden to write or mark on the blade with an electric engraving pen or other scratching methods to prevent damage to the blade body. The blade of the cutting machine blade is extremely sharp, but very brittle. In order to prevent the blade from injuring people or accidentally damaging the blade, do not touch the blade to the human body or other hard metal objects. The blades to be used should be handed over to special personnel for safekeeping and storage, and must not be shelved casually to prevent the blades from being damaged or causing accidents.

8. The premise of production efficiency is also safe operation. The cutting operator must follow the relevant requirements to make the cutting machine blade work safely on the cutting machine.
