Shure Mfg has been improving the front end manufacturing of quartz since 1984. During this time, Shure Mfg has greatly modified and improved the horizontal slurry saws used to cut quartz. And now, Shure Mfg presents 'The Wave Machine'. This machine means higher quartz & crystal blade tolerance for your slurry saw blades. This new technology for quartz cutting is referred to as 'Shure True Cut'*. This is the use of modified traditional slurry saw blades used in cutting quartz or crystal with horizontal multi-blade slurry saws to improve slurry saw blade performance.
