Checking the Slab Size

The size of a slab is one of the most important factors of quality. The blocks of absolute black come in small and big sizes. The big size blocks are expensive and small blocks are cheaper.

Big blocks are processed on multi-wire or gang-saw machines. The processing of such big machines plays an important role in the quality of granite. Material processed on big machines is more consistent in thickness. You get even thickness on big machine processing.

Small blocks are processed on vertical cutters. These are not very big machines and have an effect of vibration due to the light weight of machinery. This vibration affects the thickness of granite. The granite processed on single blade vertical cutters have thickness variation on +,- 2 mm. Getting the right thickness is also possible on these cutters, but it affects the overall production After the invention of multi-blade vertical cutters, this problem is solved, but it also needs a extra care while cutting the blocks.

Checking the Polishing

The polishing on automatic machines is always more consistent and better than polishing on single head machines. Single head machines give very good polishing but these are human handled so you may find some areas are less polished and some are more polished. The best Polishing can be achieved on Automatic machines only.

Bend in slabs.

Sometimes, while cutting the material the saw crates bent slabs. These bends can be observed by checking the sides of slabs. You can put the bundle and check the sides of slabs to observe the bend. This bend is very bad for laying the material. It may break during the laying process. If you have any doubt over the cutting, you can put a scale on the backside of material to check the bend.

Scratches

Scratches on dark materials are clearly visible. These scratches are happened due to mishandling of slabs or tiles. Tiles can be chipped in loading as well if not handled properly. It is very important to handle the loading properly. Scratches and chipping are very bad. Producers generally take extra care during the loading. If the material is not packed and loaded properly, the results may be disastrous to the clients.
