Meiwha fully automatic knife sharpener includes two models: WM-YH20MaX (oil-grinding model) and MWS20HPro (water-grinding model).These professionally designed, field-proven machines are tailored to solve the core pain points of tool maintenance in metalworking workshops, bringing efficient, precise and stable grinding solutions to manufacturers worldwide.
Industry Challenges in Tool Maintenance
In the modern metalworking and manufacturing industry, tool performance directly determines production efficiency and product quality. Dull cutting tools, rough grinding results and inconsistent tool dimensions are long-standing problems plaguing major workshops. Traditional manual grinding not only has low efficiency and high labor costs, but also is prone to human errors, leading to increased scrap rates, prolonged production cycles and unnecessary economic losses. Many small and medium-sized manufacturing enterprises and large processing plants are in urgent need of reliable, easy-to-operate and high-precision automatic grinding equipment to optimize tool management.
Dual-model solution for various workshop applications
Meiwha's new grinder series is developed based on years of industry insights and actual production demands, focusing on practicality, precision and durability. Different from ordinary grinding equipment on the market, these models have been fully tested and verified in manufacturing sites, and can perfectly adapt to daily tool grinding needs in various metal processing scenarios, truly helping enterprises reduce costs and increase efficiency.
Both models support the sharpening of flat milling, ball end milling, round nose milling, drills, and chamfering tools, with a precise grinding diameter range of 3–20 mm, covering the majority of standard cutting tools used in CNC machining workshops.
- MWS20HPro (Water-cooled Type): Equipped with a built-in water cooling system and enclosed sheet metal design, it delivers excellent heat dissipation and chip removal, ideal for high-volume, continuous production.
- MW-YH20MaX (Oil-lubricated Type): Features an oil mist collector and advanced lubrication system, providing superior anti-rust and fine-edge performance, perfect for precision tool maintenance.
Both models are equipped with φ125×10×32 mm CBN/SDC diamond grinding wheels, which offer exceptional durability and stable grinding performance. Under normal working conditions:
- MWS20HPro: Each wheel set can maintain high precision for 1600–2000 pieces of 6mm end mills.
- MW-YH20MaX: Each wheel set can maintain high precision for 2000–2500 pieces of 6mm end mills, greatly reducing consumable replacement frequency.
