The sawing of granite should be paid special attention to the selection of sawing parameters with a diamond circular saw blade.
Preferably, the diamond saw blade first saws the silicate brick or the
like with a small sawing force to facilitate the cutting. The saw blade
has a peripheral speed of 25 mm-30 m/s and a feed speed of 0.4 m.
1.Om/rain, the sawing depth is 25mm~40mm. The diameter of the diamond
saw blade is 320-1250mm, the thickness of the cutter head is
3.1mm~7.0mm, and the 50/40 mesh round diamond-like synthetic diamond and
copper-nickel alloy are used for bonding. The cutter head is welded to
the granite base use for cmm machine in a high frequency furnace at a
temperature of 650 ° C by a silver soldering technique.
It should be noted that not all granite is suitable for making the base of such a high precision measuring device. Granite with a
fine-grained structure with a small linear thermal expansion coefficient
should be used.
