6. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
This machine is designed for grinding hard alloy saw blades. Follow these steps for effective grinding:
- സോ ബ്ലേഡ് ഘടിപ്പിക്കുന്നു: Securely place the saw blade onto the saw blade holder. Ensure it is centered and stable. The machine accommodates saw blade diameters from 80mm to 700mm.
- Adjusting the Positioning Pin: Use the adjustable surround type plate and positioning pin to align the saw tooth you wish to grind. This ensures each tooth is presented to the grinding wheel consistently.
- Setting Blade Diameter and Tooth Size: Adjust the machine's settings according to the specific diameter and tooth size of your saw blade. This will help achieve the best grinding position.
- Adjusting Blade Angle (Horizontal Rotary Slide): Use the horizontal rotary slide to set the desired blade angle. This mechanism allows for changes in the blade's angle or magic (relief angle).
- Adjusting Feed Angle (Rotary Table): The saw board is equipped with a rotary table. Adjust this table to set the feed angle of the cutter. The rotary table includes a slider, mandrel, and limit screw for convenient operation and to ensure grinding to the radius of the center.
- Grinding Oblique Edge Sawteeth (Head Rotary Mechanism): For saw blades with oblique edge sawteeth, utilize the head's +/-20 degree rotary mechanism. This allows for precise grinding of these specialized tooth profiles. Refer to Figure 3.3 for the grinding wheel adjustment scale and Figure 3.4 for the rotary frame angle adjustment.
- അരക്കൽ പ്രക്രിയ: Once all adjustments are made, turn on the machine. Carefully and slowly bring the saw tooth into contact with the grinding wheel. Apply gentle, consistent pressure. Grind each tooth individually, maintaining the set angles and feed.
- പൂർത്തീകരണം: After grinding all teeth, turn off the machine and disconnect it from the power supply. Carefully remove the sharpened saw blade.

9 ഉപയോക്തൃ നുറുങ്ങുകൾ
- ഗ്രൈൻഡിംഗ് വീൽ മാറ്റിസ്ഥാപിക്കൽ: If you notice a decrease in grinding efficiency or quality, it might be time to replace the grinding disc. Ensure you have spare discs on hand for continuous operation.
- Practice with Old Blades: If you are new to saw blade grinding, consider practicing on an old or scrap saw blade to get a feel for the machine's adjustments and the grinding process before working on valuable blades.
- സ്ഥിരമായ സമ്മർദ്ദം: Maintain consistent, light pressure when grinding each tooth. Excessive force can lead to overheating, damage to the blade, or premature wear of the grinding wheel.
