What is the difference between the leveling effect of resin grinding disc and metal grinding disc? How to choose?

Shearing has always been a difficult problem in construction, and it is very important to choose the right cut.

There are too many products, which will inevitably make it difficult for people to choose. So some customers asked me, which type of abrasive sheet is good for cutting? There are no good products in this world, only good choices. Stone care is a technical task, and in many cases it is necessary to choose products based on rich experience and adapt to local conditions.


At present, there are two types of leveling films (cut-off films) on the market: resin films and metal films.


First, resin sheet


The resin sheet uses the formula of "resin binder + abrasive", and there are large abrasive particles.


Advantage:

The price is cheaper than the metal sheet. Because of the fixed cushioning effect of the resin, it is not easy to scratch the stone when grinding, and it will not show scratches that are difficult to repair.


Disadvantages:

Although the resin cutting edge is very sharp, the grinding ability is still inferior to that of the metal edge.


In addition, the hardness of the resin is lower than that of stone after all. When encountering a large level difference, it is easy to collide with the stone cutting edge due to the high-speed operation of the machine and break.


Second, the metal sheet


The metal sheet adopts the formula of "metal + abrasive", and the abrasive is cast into the metal base.


Advantage:

Sharp, very sharp, strong cutting ability, can easily level large height differences.


Disadvantages:

If the grinding is not fine, it is easy to leave scratches that are difficult to repair. High demands are placed on subsequent abrasive discs.


Summary


Sharpness: metal leveling sheet > resin cutting sheet

Optimizing ability: resin cut-out sheet > metal leveling sheet

Price: metal leveling sheet > resin cutting sheet


Choice


For general height differences, you can choose resin cutouts; for particularly serious height differences, such as exaggerated to 1㎝, choose metal cutouts.

For soft marble and limestone, resin cutting blades are selected. Metal cutting blades have too strong grinding capabilities and are easy to over-grind.

Resin cutouts can solve most of the stone cutout problems. For particularly hard stones, you can choose metal cutouts.

Metal cutouts are recommended for terrazzo and concrete floors, and resin cutouts are not recommended.


V. Experience Sharing


Metal cutting blades are easy to slip and not open when encountering relatively smooth granite. At this time, you can use an angle grinder and a grinding wheel to polish the smooth surface of the granite and grind it.
