The use of grinding tools in the production process involves many variables. If everything is not set up correctly, you may encounter some abrasive cutting disc problems.
It is difficult to figure out what the reason is. We have compiled a list of some common abrasive cutting disc problems for troubleshooting. Sometimes the solution is easier than you think!
Whether it is tremors, burns or completion problems, we have seen them. Check out some common abrasive cutting disc problems and how to fix them!
Did the abrasive cutting disc disappoint you?
You may feel frustrated as you work hard to finalize the workpiece. Grinding is an important part of every industrial production environment.
If you see or hear something weird, it is probably a common problem. There are too many subtle changes in the setting on the grinding machine, which may affect the supply of coolant lubricant on the grinding machine or cause wear.
When troubleshooting for the first time, be sure to make some minor adjustments to the machine. Most importantly, don’t forget to stay safe while working around dangerous machines.
Do you see burn marks?
Grinding burns can be one of the most common problems with grinders. Burns in the edge regions of the part will cause tiny microcracks and brittle surfaces.
Due to the high friction, the abrasive parts produce high heat. It is expected that some of the heat will enter the part, but too much heat will burn the workpiece. Combustion occurs when the feed is too high and the coolant is insufficient.
If any traces of burning are found on the workpiece, it is likely that friction is due to insufficient coolant. The coolant lubricant absorbs heat and carries it away. Sometimes a lot of coolant lubricant is used, but it still burns.
This is because there is a large amount of coolant, but it cannot reach the processing position at the proper speed at the proper position.
Is the nozzle aligned?
If your nozzles are not properly aligned, the coolant lubricant will not be properly supplied to the machine. Make sure you have considered the supply of coolant lubricant.
It is recommended to use a needle tip to supply coolant to the processing site in a targeted manner. This is important to avoid overheating and burning.
Properly aligned nozzles not only keep the coolant in the correct machining area, but also help to saturate the abrasive cutting disc. This will fill the free pore space of the abrasive cutting disc with a coolant lubricant to prevent burning on the workpiece.
Do you hear Chat?
Start to hear the terrible vibration we call trembling? This is a common problem with grinders and can be even more frustrating if you can’t find them. There are several ways to solve the chatter problem.
Check the blade to see if it is properly clamped. It may be loose during grinding. Your abrasive cutting discs may also be unbalanced, so please check them out too. If your grinding is too heavy, you should slow down the feed.
Adjusting the steering abrasive cutting disc
When performing lateral grinding, the abrasive cutting disc can be more freely cut by reducing the lateral grinding cost. This prevents extra bounce and vibration. You can also try to use softer abrasive cutting discs or make the abrasive cutting discs softer.
To make the abrasive cutting discs softer, it is recommended that you try one of the following to see what it does: increase abrasive cutting disc feed, increase work spindle, reduce abrasive cutting discspindle, reduce abrasive cutting disc diameter or reduce coolant lubricity.
Adjust your dress
You can also try to adjust the dress. This will make your abrasive cutting discs cut faster and more freely. Remember that the faster you wear, the higher the surface finish. Therefore, you may have to use it before you can use it properly.
Finally, the machine may cause some vibration on the floor. Carefully check for loose screws or loose things during installation. This includes looking at the belt to see if the belt has the correct tension and no defects.
Have you found an unstable size?
If you find that the dimensions are unstable or the workpiece is not accurate, the triangle arms on the upper and lower sliders may not be properly adjusted. Place the rails parallel to the tread.
This may also indicate that the workpiece is not properly centered or the height is incorrect. In addition, you must ensure that the abrasi ve cutting discspecifications are correct. Try using a softer ramp wheel. Balance and correct the wheels and adjustment wheels.
Coolant may work, so check the quantity and quality carefully. Finally, the size may be different because your work is not correct. This may affect the size of the future.
The completion is not good?
Some things may cause your work to be ineffective. Here, please check to see if your settings are correct. Then, check the coolant. If you have enough food, will it be dirty? Make sure it is clean.
Finally, check the surface of the abrasive cutting disc for oil. This may also affect your completion.
Resin bonding life
Use a resin bonded abrasive cutting disc? The poor result may be because the life of this abrasive cutting disc is shorter than other abrasive cutting discs. The advantage of these abrasive cutting discs is that they have the best self-sharpness. But unfortunately, they won’t last long.
Resin bonded abrasive cutting discs are highly efficient, but to extend their life, contact the factory to let them know. They will adjust the production formula to extend their service life. You can also choose a finer gravel number to extend its life.
Good luck!
