When learning the knowledge about TCT saw blade, also known as the cemented carbide saw blade, have you heard such concept that is cemented carbide guide block and do you know its role when taking cutting works? This is the exact article about cemented carbide guide block for readers to learn it clearly.
In fact, cemented carbide guide block has played the same function as the ball bearing guide block, the only difference is that they have different appearance, the ball bearing guide block is the round ball while the cemented carbide guide block is the square shape. Similar to ball bearing guide block, there would be right gap between guide block and saw blade.
When talking about the stress from cemented carbide guide block, as usual, it would be the pressure from mechanical spring, saw blade would be kept down tightly with such tension.
No matter it is the cemented carbide guide block or the ball bearing guide block, there would be abrasion on them after a long time using, which is inevitable. If the guide block is damaged at the groove location, the saw blade is likely to contact with the side guide block, as a result, saw teeth would be damaged and abraded, which would lead to excessive vibration and saw blade’s working life would be greatly shortened under such condition. What’s more, if guide block is damaged badly, saw blade is likely to be broken because of such side guide block during cutting process, which would be dangerous for cutting workers.
Once the guide block is abraded, then it will directly abrade the back cutting edge of saw blade, gradually, there would be one closed angle on saw blade body, and its working life would be shortened due to such unusual design. You know, the closed angle part would become the stress growth points for bending. At the same time, once the guide block is got stuck, the same problem would be resulted.
It is recommended to buy right saw blade, for example, the width of saw blade should be suitable for the saw machine, however, if sometimes because of negligence, the width of saw blade is not suitable, saw teeth is likely to contact with side guide block directly, both the saw blade and guiding device would be damaged under such circumstance, in order to avoid such condition, you’d better pay attention on its label on saw blade body.
