System and method for cutting granite or similar materials
View Patent ↗Improved methods including providing a frame saw system having multiple blades for cutting slabs of masonry materials. The improved methods allow for cutting masonry materials into slabs having surface small deviations. A process for cutting masonry blocks of granite, marble, rock, and the like, also includes positioning a support structure of a unifying material perpendicularly across the blade of the frame saw, wherein the support structure is adhered to at least one of the blades for keeping the blades in fixed relative positions, subjecting the block to a sawing operation using the frame saw, and at least substantially removing the support structure as the blades become submerged in the block.
1. A method for cutting a block of granite, marble, or like material, comprising:
providing a frame saw comprising a plurality of spaced apart blades;
positioning a support structure of a unifying material perpendicularly across the blade of the frame saw, wherein the support structure is adhered to at least one of the blades for keeping the blades in fixed relative positions;
subjecting the block to a sawing operation using the frame saw; and
at least substantially removing the support structure as the blades become submerged in the block.
2. The method of claim 1 , wherein the positioning comprises injecting an expandable polymeric foam mixture in between the saw blades, whereby the expansion of the foam keeps the blades in fixed relative positions.
3. The method of claim 2 , wherein the foam comprises a polyurethane foam.
4. The method of claim 1 , wherein the blades are connected on both ends to a frame by tensioning rods.
5. The method of claim 1 , further comprising applying a compressive force perpendicularly to the parallel blades.
6. The method of claim 1 , wherein the blades comprise superabrasive-containing segments.
7. The method of claim 1 , wherein the sawing operation comprises using a slurry of steel shot and lime dispersed in water.
8. The method of claim 1 , wherein the sawing operation comprises using cooling water.
9. A method for cutting a block of granite, marble, or like material, comprising:
applying a skim coat onto a surface of a block of material to form a substantially even surface that is substantially devoid of high points, low points, and drill holes:
providing a frame saw system comprising a plurality of spaced apart blades;
positioning a support structure of a unifying material perpendicularly across the blades of the frame saw, wherein the support structure is bonded to at least one of the blades for keeping the blades in fixed relative positions;
subjecting the block having a skim-coated even surface to a sawing operation using said frame saw system so as to divide the block into multiple slabs; and
at least substantially removing the support structure as the blades become submerged in the block.
10. The method of claim 9 , wherein the skim coat comprises cement and sand.
11. A method for the manufacture of slabs by sawing comprising:
providing a frame saw system for sawing a block of marble, granite, or masonry material, wherein the frame saw system comprises multiple blades connected to a frame;
positioning a support structure of a unifying material perpendicularly across the blade of the frame saw, wherein the support structure is bonded to at least one of the blades for keeping the blades in fixed relative positions;
subjecting the block to a sawing operation using the frame saw system so as to divide the block into multiple slabs; and
at least substantially removing the support structure as the blades become submerged in the block.
12. The method of claim 11 , wherein the multiple manufactured slabs have surface deviations of less than 1 mm.
13. The method of claim 11 , further comprising applying a skim coat onto a surface of the block of material before the sawing operation to form a substantially even surface on the block.
