Double sided synchronous precision grinding: Both sides of the tooth surface are polished simultaneously, with uniform force on the left and right teeth, symmetrical and regular tooth shape, and minimal dimensional error. Precision stability and durability: The heavy-duty and stable body has low vibration during operation, and is not easily displaced during long-term processing. The batch grinding accuracy is uniform, and the consistency of the finished product is high. High sharpness and smooth cutting: precise replication of standard tooth angles, smooth blade edge after grinding, cutting without burrs, deviation, or tooth breakage, and smooth cutting surface.
