Saw Blade Grinder | Huashun Machinery

Saw blade grinder/ sharpener repair and remachine various types of saw blades (e.g. circular saw blades, band saw blades) by machining the teeth with grinding wheels or diamond. It restores the cutting ability of the saw blade and extends its service life.

Classification of Saw Blase Grinder

Classification by use

• Circular saw blade grinder: Specially used for grinding circular saw blade teeth.
• Band saw blade grinding machine: Used for sharpening the teeth of band saw blades.
• Frame saw grinding machine: Suitable for repairing the teeth of frame saw blades.

Classified according to the degree of automation

• Manual grinding machine: Manual operation, suitable for small processing tasks.
• Semi-automatic grinding machine: part of the action is automatically completed by the machine tool, high efficiency.
• Full-automatic grinding machine: fully automated, suitable for large-volume processing tasks.

Classified by control method

• Conventional grinding machine: Mechanical control, suitable for standard tooth shapes.
• Numerical control grinding machine (CNC): Complex tooth shapes are processed and controlled with high precision by the CNC system.

Main components of saw grinding machine

• Bed: Supports the entire machine structure to ensure stability and rigidity.
• Grinding wheel spindle: drives the grinding wheel to rotate at high speed, which is the key component for grinding saw teeth.
• Working table: installs the saw blade or the saw blade, and provides the function of adjusting the angle of the saw blade.
• Clamping device: Used to fix the saw blade to ensure that the position is not shifted during the machining process.
• Tooth spacing adjustment mechanism: used to adjust the tooth spacing of the saw blade to adapt to different tooth shapes.
• Cooling system: Provide coolant to reduce the grinding heat and avoid the saw blade being deformed by heat.
• Automatic feeding system: automatically adjusts the relative position of grinding wheel and tooth shape to maintain consistent machining effect.
• Numerical control system: Provide high-precision parameter setting of tooth shape and machining path planning.

Technical Parameters

• Applicable saw blade diameter range: such as 50mm-1200mm (circular saw blade).
• Adjustable range of tooth pitch: e.g. 5mm-25mm.
• Range of tooth angle: front angle and back angle adjustable (e.g. -5° to 30°).
• Grinding wheel speed: e.g. 3000-8000 rpm.
• Feed speed: e.g. 0.5mm/sec-5mm/sec.
• Control accuracy: machining accuracy can reach ±0.01mm (CNC equipment).

Common teeth processing

• Triangular teeth are commonly used in metal cutting saw blades with simple tooth shape.
• Left and right teeth are commonly used in woodworking saw blades with high processing efficiency.
• Trapezoidal teeth are used for cutting hard materials with high wear resistance.
• Composite teeth are used for complex material cutting by combining various tooth shapes.

Maintenance and care

• Regularly clean and remove metal chips or sawdust from the surface of the machine.
• Inspect grinding wheels to ensure that they are free of cracks and wear evenly.
• Lubrication moving parts add lubricant regularly to prevent parts from wearing out.
• Coolant replacement keep the cooling system clean and replace the coolant regularly.

Advantages

• Automatic detectionMonitoring of saw blade processing status by sensors for automatic adjustment.
• Complex tooth ahape programming CNC sharpening saw supports fast programming and machining of complex tooth shapes.
• Multi-functional design supports the processing of multiple types of saw blades and improves equipment utilization.

Application areas of saw sharpening machines

• Woodworking industry: repair of woodworking circular saw blades and band saw blades to ensure processing quality.
• Metalworking: processing of HSS or carbide saw blades for metal cutting.
• Furniture manufacturing: customizing saw blades to meet specific cutting needs.
• Paper industry: resharpening saw blades for cutting cardboard.
