Line speed is not high , an increase in cutting efficiency , will reduce the life of the blade

feed rate , depending on the processing of the material properties of each material when the cutting depth must have a certain range of the feed rate , if the speed is too high, will accelerate the masonry drill bits  wear of diamond or even fall off , causing the blade consumption too fast , if the speed is too low , then they will make the process of self-sharpening blades can not be normal , so " blunt , skid " lost cutting capacity . Under normal circumstances , the feed speed is slower when cutting , sawing should be in uniform for the common typical materials , when the cutting depth is 20mm, recommend the following feed rate table for your reference , when the thickness changes, the cutting speed can be press the cutting area (cm2/min) to conversion .
Tip: The first feed or each piece of board should be reduced by half for the first three walks .
Common materials saw feed speed unit : mm / mi the cutting depth for medium hard stone such as marble , limestone cut through at once , for hard stone and abrasive such as large granite, sandstone should step cutting, saw cutting granite monolithic , eating knife depth is generally 10-20mm , depth of cut marble cutting 50-100mm, more than double-sided cutting hard granite , depth of cut of each 3-5mm, should be based on the turbo blades  hardness of the stone , using a saw blade and the fixed performance , efficiency recommend the following table for your reference.
Common materials cutting efficiency table Note: " 1 " indicates low power finishing ; "2" indicates a high power roughing. the blade rotation direction of the same stone as the feed direction along the cutting , contrary to reverse cutting, and reverse cutting, due to an upward vertical force component , in the form of stone off potential, therefore , is a solid stone, under the same conditions next , you should try using tct circular saw blade  smooth cutting . When using reverse cutting, cutting depth to be reduced , generally reduced to shun cutting 1/3-1/2  In summary, the basic requirements for selection cutting process are: low hardness, good stone cutting performance can be deeply walking , brisk walking contrary shallow cut , ie corresponding to the same stone and saw and saw blade should be cutting efficiency, cutting board , good quality, long life blade and matrix process parameters prevail , the four complementary and mutually dependent , must not generalize . For example, when the saw blade cutting speed can not be maintained , indicating a blunt blade , cutting depth should be reduced while increasing the cutting speed to sharpening blades.
