Integrated grinding with complete functions: simultaneously polish the tooth top and tooth surface, repairing the front angle, rear angle, and tooth top plane in one go without changing the machine model. The complete set of conventional saw blades can be ground in one step. Grinding standard, easy to use for cutting: the tooth top is leveled and even, the tooth surface angle is precise and uniform, the saw blade is sharp and durable after grinding, the cutting is smooth, without shaking or deviation, and the cutting surface is free of burrs. Dual use for both dry and wet, protecting the saw blade: can be ground dry or wet with water, with fast cooling and heat dissipation, preventing tooth burning, annealing, and breakage, and extending the service life of the saw blade. Easy to operate, quick to get started: simple control panel, automatic indexing and gear rotation, one click debugging, ordinary workers can quickly learn from scratch, saving labor. Stable body and long-lasting precision: The thickened cast iron body has low vibration during operation and is not easily displaced during long-term use. The grinding accuracy is stable and durable.
