Home / Product / MYD Series Circular Knife Grinding Machine

Circular Blade Grinder Supplier

MYD Series Circular Knife Grinding Machine has a precision grinding system that can grind the edges and planes of various types of slitting circular knives. Through precise mechanical structure and advanced grinding technology, the machine can complete fine grinding of the edge in a short time, greatly improving production efficiency. At the same time, the uniformity of the grinding system ensures the uniform sharpness of each part of the edge, avoiding cutting problems caused by uneven edges.
In addition to edge grinding, the MYD Series Circular Knife Grinding Machine also has a surface grinding function. This function is of great significance in ensuring the flatness and finish of the circular blade. Surface grinding can remove tiny unevenness and defects on the blade surface, making the blade surface smoother, thereby reducing cutting resistance and improving cutting efficiency.

MYD Series Circular Knife Grinding Machine Industry knowledge

I. What is Circular Blade Grinder?​

Circular Blade Grinder is a specialized equipment designed for precision grinding and sharpening of various circular blades. Unlike general-purpose grinding machines, it focuses on optimizing the cutting edge geometry, sharpness, and dimensional accuracy of circular blades—through controlled grinding parameters (such as feed rate, grinding wheel speed, and pressure), it can restore worn blades to their original performance or enhance the precision of new blades for subsequent cutting operations.​


Jiangsu Best CNC Machinery Co., Ltd., with 35 years of experience in sharpening machine manufacturing, specializes in producing high-precision circular blade grinders, including CNC automatic models (e.g., MYD-K series) and heavy-duty grinding models. The company has established an engineering and technology research center, independently developed all products with proprietary intellectual property rights, and obtained 10 national authorized patents (including 2 invention patents), with an annual production capacity of approximately 300 units.​

II. Key Features of Circular Blade Grinder​

High Precision Performance: It can achieve ultra-high grinding accuracy, with basic accuracy up to 0.02mm and advanced models (such as ultra-precision grinders) reaching ±0.005mm/m. This ensures the circular blade maintains stable cutting accuracy, avoiding material waste caused by blade deviation.​


Strong Adaptability: It supports grinding of circular blades made of various materials, including high-speed steel, cemented carbide, ceramics, and diamond coatings. It can also handle blades of different sizes, with a common processing diameter range of φ50-φ800mm (customizable for larger sizes).​


Durable and Efficient: The core components (such as grinding spindles and servo motors) are made of high-quality materials, ensuring long-term stable operation with low failure rates. For batch processing, automatic models can complete grinding of a single blade in 5-12 minutes, significantly improving efficiency compared to manual sharpening.​


Intelligent and User-Friendly: Advanced CNC models are equipped with automatic grinding wheel dressing, wear detection, and parameter storage functions (supporting 100+ sets of processing programs). Operators only need to set parameters and load blades, reducing manual intervention and skill requirements.​


Environmental Adaptability: It can be customized with IP54 waterproof and dustproof enclosures and high-temperature resistant motors, adapting to harsh working environments such as high-humidity paper mills and dusty wood processing plants.​

III. Circular Blade Grinder Applications in Various Industries​

1. Paper and Printing Industry​
In paper slitting and printing film cutting processes, circular blades require high sharpness and flatness to avoid paper edge burrs or film tearing. Circular blade grinders can restore the blade's cutting edge to a roughness of Ra≤0.2μm, ensuring smooth material cutting. For large-diameter paper slitting blades (φ800-φ1200mm), heavy-duty grinders with reinforced cast iron beds (vibration ≤0.005mm) are used to maintain grinding stability.​

2. Food Processing Industry​
Food packaging film cutting and frozen food slicing blades have strict hygiene requirements. Circular blade grinders for this industry adopt 304 stainless steel bodies and food-grade lubricating systems to prevent contamination. The grinding process avoids high temperatures (using low-temperature grinding technology, ≤40℃) to prevent blade material deformation, ensuring compliance with food safety standards (such as FDA).​

3. Woodworking Industry​
Wood cutting blades are prone to wear due to high friction. Circular blade grinders can quickly repair worn edges, extending blade service life by 3-5 times. For wood chip blades, the grinder can customize a 60° obtuse cutting edge to enhance impact resistance, reducing blade chipping during hardwood cutting.​

4. Textile and Fiber Industry​
Textile fabric and chemical fiber cutting blades need precise edge angles (usually 30° acute angles) to avoid fiber fraying. Circular blade grinders use micro-feed systems (minimum feed 0.001mm) to accurately control the edge angle, ensuring uniform fiber cutting. The equipment's automatic parameter storage function also supports quick switching between different fabric blade specifications.​

5. Medical and Electronic Industry​
Medical infusion tube cutting and electronic film (e.g., lithium battery pole piece) cutting require ultra-high precision. Ultra-precision circular blade grinders (accuracy ±0.005mm/m) are used to grind blades, ensuring the cutting edge has no burrs (Ra≤0.1μm). The non-oil lubrication design of the equipment also prevents oil pollution of medical or electronic materials.​

6. Plastic Processing Industry​
Plastic sheet and pipe cutting blades are resistant to chemical corrosion. Circular blade grinders use diamond grinding wheels to process cemented carbide blades, enhancing the blade's wear resistance against plastic melting adhesion. The grinder's detection system (laser diameter measuring instrument, accuracy ±0.001mm) ensures the blade's circularity error ≤0.003mm, avoiding uneven plastic cutting.​
