Significant polishing effect Features: Elastic polyurethane polishing wheel has strong wear resistance, good self-sharpening, contains silicon carbide abrasive, sharp and durable. Uniform microporous structure, with super toughness, elasticity. Ideal dry and wet polishing effects. Particles fall off directly during polishing without dust. Long service life. Significant polishing effect Product parameters: 6 inch diameter, 1/2 inch spindle, 1 inch thickness, hardness 70A-75A (shore), grit 2000. Please choose the appropriate polyurethane polishing wheel according to the diameter and speed of your machine spindle. Polyurethane polishing wheels are often used with some lubricants.It can partially replace sandpaper and scouring pad wheels Safety and precautions: The speed of the polyurethane polishing wheel is generally 1500-3000 rpm. Choose the correct speed and pressure when polishing. Start polishing slowly and with low pressure. Especially for thin-walled parts, choose a low speed for polishing. Too high a speed can easily burn the workpiece. During the polishing process, you need to move the polishing position quickly to prevent burning the workpiece and uneven polishing After-sales: Each of our products is inspected and packaged, but accidents cannot be ruled out.
