MF2718B-I Universal Sharpening Machine

For industrial production (e.g., mechanical processing, tool manufacturing), industrial-grade universal knife sharpeners/drill sharpeners are recommended for high precision and multi-type tool adaptation; commercial desktop sharpeners are ideal for catering/food processing, emphasizing fast sharpening and easy hygiene maintenance; portable electric/manual sharpeners suit home use or small workshops, featuring simple operation and compact size; agricultural-specific sharpeners (e.g., harvester blade sharpeners) are recommended for agricultural and horticultural scenarios, adapting to outdoor operation needs.

Grinding precision directly determines the sharpness and service life of the tool edge: industrial-grade equipment (precision ±0.01mm) is suitable for scenarios requiring high processing accuracy (e.g., mold processing, precision tool production); commercial/home-use equipment (precision ±0.1mm) can meet routine needs such as daily cutting and trimming. Insufficient tool edge precision may cause processing jams, food waste, wood cracking, etc.

Universal knife sharpeners can adapt to various metal tools such as turning tools, milling cutters, and drills; kitchen knives (e.g., chef's knives, fruit knives) can use commercial/home desktop sharpeners; saw blades, planer knives, etc., require special sharpeners (e.g., saw blade sharpeners, woodworking planer sharpeners). Due to their special edge structure, dedicated equipment ensures uniform grinding and avoids tool damage.

① Wear protective equipment (gloves, goggles) to avoid splashing metal shavings; ② Adjust the grinding wheel speed (low speed for hard tools, medium-high speed for soft tools) and grinding angle (15-20° for kitchen knives, 20-30° for turning tools) according to the tool type; ③ Press the tool lightly during grinding, move at a constant speed, and avoid local overheating; ④ Polish the edge with a fine oilstone after grinding and clean the equipment shavings. It is recommended to watch operation videos or consult the manufacturer for guidance first.

Grinding wheels need regular replacement, and the frequency depends on usage frequency and grinding materials: industrial-grade equipment (8 hours of daily use) is recommended to be replaced every 3-6 months; commercial equipment (4-6 hours of daily use) every 6-12 months; home-use equipment (2-3 times a month) can be used for 2-3 years. If the grinding wheel has cracks, uneven wear, or significantly reduced grinding efficiency, it must be replaced immediately.
