High Efficiency .accurate.stable.work 24hour Continuously Precise grinding, meeting the accuracy standard Dual position synchronous grinding: Complete synchronous precision grinding of tooth top and tooth surface in one, with uniform angle standards and regular tooth shape without deviation Geometric angle replication: Accurately restoring the original cutting angle, the sharpness after grinding is comparable to that of a new saw blade, and the cutting is smooth without broken teeth or burrs Stable grinding forming: low vibration, stable positioning, eliminating serrated eccentric wear and jumping wear, and achieving high consistency in batch processing accuracy
