steel grooved saw blade for granite cutting with steel grit flow
fast speed and low cost
ApplicationThe steel grooved saw blade is specially designed to be used on the new high gang-saws for producing large granite slabs, which are to work with cutting fluid mixed well by water, steel grit and lime together for cutting granite blocks.Saw Blade Characteristics And Common Specification TableWhen ordering, please clear the following information to us.A. Width B. ThicknessC. Total lengthD. Distance between the hole-centersE. Diameter of holesBasically requirement of correct application I.Correct installation(1). Blades should be parallel with the central line of the blade holder and assuring of blade vertical, otherwise, which leads to extra large sawing gap, only one side of blade to be abraded,which cause concave in middle blade and bending severity after a finish of a trolley of granite blocks. (2).Blade up to enough tension. Blade should be installed tightly between the front heads on blade holder. After checking verticality, hydraulic extension device should be equipped firstly for individual extension force to extend the blade at full, or the blade can not be of enough tension. Basically, tension force is decided by the size of new blades, for example, in total 8 tons for 100x4.5mm, 9.5 tons for 120x4.5mm. If the blade is not up to enough tension,then quivering is too severe when sawing and concave in middle of blade and bending severity after removal. II.Appropriate composition of cutting fluid.(1) In general, the size of grit is 1/4-1/5 of thickness of blade, and small grits are suitable for thin blade, opposite for the thick one. Otherwise, which may lead to slab surface rough and cutting abilities low.(2) Appropriate grit capacity and cutting fluid density. Less steel grit input will cause poor cut abilities and even are not able to saw stone. In contrary, too much accumulated grits in the gaps will lead to blade running out of order.III. Proper cutting down speed. At the beginning when blades are not going into stone, cutting speed should be lower, when the blade going into stone entirely, speed can be faster. The cutting speed is decided by the block’-s hardness. Too low speed will lead to low efficiency, however, too fast speed will cause the saw blade quivers, electric current of mainframe too large and trouble sawing happens.
