Cup grinding wheels are made from Tough Aluminum Oxide Al₂O₃ or Silicon Carbide SiC grains. Their standard diameters range from 50 to 180 millimeters. The abrasive section height is typically 40 to 80 mm. Grit sizes range from coarse P24 to fine P600 for various applications. The bond used is heat-treated phenolic resin for high strength. The recommended maximum operating speed is 2800 RPM for a 125 mm wheel. They are mounted on industrial drills or angle grinders. Primary applications include finishing concave surfaces, weld cleaning, and metal preparation.
Abrasive rolls are constructed with a polyester cloth or kraft paper backing. Standard roll widths are 50 to 1370 mm with lengths up to 50 meters. Their grit range is P40 to P800, offered with Hook & Loop or plain adhesive backing. Grain density varies in semi-open, open, and closed coat models. The backing cloth has a minimum tensile strength of 80 Newtons per centimeter. This product is used for finishing flat surfaces, orbital, and belt sanding machines. They can be custom-cut to size with scissors or a blade. High flexibility allows use on curved surfaces and sharp corners.You can order and buy abzar jahan boresh from Iran by contacting us through whatsaap and email.

Differences and Advantages of Flap Sanders and Roller Sanders
Flap sanders operate with a high-speed rotational movement. This tool enables rapid material removal. Its relatively small contact area is ideal for curved surfaces. Roller sanders function with a linear oscillating motion. This mechanism prevents gouging on the surface. It is highly suitable for finishing flat and even surfaces. The advantage of the flap sander lies in its high material removal rate and operation speed. The advantage of the roller sander is its final finish quality and absence of circular scratches. The choice between them depends on the material type and required surface quality.
