Circular Blade Sharpening Machine Factory

Product Introduction

Shengong SG-026 Circular Blade Sharpening Machine is a professional CNC grinding machine designed for the maintenance and sharpening of large circular saw blades. It is suitable for grinding 800-2200 type alloy circular saw blades. As a high-performance wood blade sharpening machine, SG-026 helps restore blade sharpness, improve cutting accuracy, and extend blade service life.

The fourth-generation automatic saw blade sharpening machine features an optimized structure, simple operation, and precise grinding performance. It can adjust tooth cutting angles, tooth numbers, and tooth depths according to different blade requirements. The machine supports various blade materials, including HSS saw blades and manganese steel flying saw blades, as well as different tooth shapes such as left-right teeth, curved teeth, triangle teeth, and high-low teeth.

• Precision Grinding Performance: Equipped with a professional grinding system, the machine precisely sharpens each tooth to maintain consistent blade sharpness. This helps reduce cutting deviation and improves the quality of wood processing.
• Adjustable Grinding Speed: The grinding speed and processing time can be adjusted according to different blade sizes, materials, and wear conditions, allowing flexible operation for various production requirements.
• High-Quality Copper Motor: The machine uses a full copper motor that provides stable power output and reliable performance, supporting long-term continuous operation.
• High-Power Operation: The powerful drive system ensures smooth grinding performance for large circular saw blades, improving efficiency and reducing downtime.
• Low Noise and Low Loss Design: The optimized structure reduces operating noise while minimizing grinding wheel and blade wear, helping customers lower long-term operating costs.

The SG-026 Circular Blade Sharpening Machine is equipped with a complete grinding system, including a blade fixing mechanism, automatic tooth feeding mechanism, automatic blade pressing system, grinding wheel mechanism, electrical control system, and cutting fluid cooling system. Through automatic positioning and stable grinding control, the machine improves sharpening efficiency and processing accuracy, providing reliable blade maintenance solutions for wood processing companies.

Product Applications

The Circular Blade Sharpening Machine is mainly used for sharpening and maintaining circular saw blades in the wood processing industry. During raw wood processing, circular saw blades are widely used for cutting, splitting, and sizing operations. After long-term use, saw blades may become dull, reducing cutting efficiency and affecting finished wood quality.

By using the SG-026 wood blade sharpening machine, worn blades can be restored and reused for different wood processing applications:

• Raw Wood Cutting and Processing: The sharpened blades can be used for cutting raw logs into basic materials such as wooden boards and timber sections, improving cutting stability and material utilization.
• Wood Board and Timber Size Cutting: In furniture manufacturing, construction materials, and packaging wood production, precise cutting is required to achieve smooth edges and accurate dimensions. Properly sharpened blades help improve processing quality.
• Hardwood and Softwood Processing: The machine allows flexible adjustment of grinding parameters, making it suitable for different wood materials, including various hardwood and softwood applications.
• Sawing Line Blade Maintenance: For companies operating continuous wood cutting production lines, regular blade sharpening helps reduce blade replacement frequency and maintain stable production efficiency.

Through professional blade sharpening, companies can reduce cutting resistance, minimize material waste, and improve the consistency of finished wood products.
