Cartridge Rolls are typically used for finishing inside surfaces and inside corners where other sorts of abrasive cannot reach. The small diameter of cartridge rolls is used on high-speed air tools to realize an appropriate surface for grinding speed. Typical speeds are 20,000 RPM and above. The various shapes are available to suit the appliance geometry. X weight alumina is the most typical material, with J weight was sometimes chosen for increased flexibility and fewer aggressive cuts.
Cartridge Rolls even have a multi-layer coiled construction and expose sharp new cutting abrasives as each layer wears. Their shape is suitable for finishing operations, irregular concaves, contours, dead-end holes, and channels. They also help with deburring, blending tool mark removal, and flash removal.
They are also designed to interrupt down during use revealing a subsequent layer of abrasive. The backing cloth is usually cotton. Because the merchandise is meant to interrupt, cartridge rolls are rarely manufactured with technical grains like zirconia or ceramic. This is often because the backing breaks down before the alumina grain is entirely dulled. Thus the self-sharpening characteristics of the technical grains aren't realized during use.
Standard abrasive cartridge rolls are excellent for sanding and finishing. The cartridge rolls are used on inside surfaces and inside corners on high-speed grinders. The aluminum oxide coating on cartridge rolls provides a flexible hand-sanding process, especially in finishing the metalwork.
On inside surfaces and inside corners where other abrasive types do not reach for flash removal and polishing, cartridge rolls are usually used. They have to be used on high-speed air machines to get a suitable surface grinding speed because of their limited diameter.
Some of the other typical applications of cartridge rolls include:
The sandpaper cartridge rolls often have a multi-layer helical structure, and as each layer wears, they reveal sharp new cutting abrasives. Their form is acceptable for finishing operations, irregular concaves, contours, dead-end holes, and channels. They also assist with deburring, removal of blending tool labels, and removal of flash.
While deburring standard abrasives, cartridge roll breaks down to expose the next abrasive layer. For extending the product life, cotton is the primary backing cloth. Few cartridge rolls are composed of abrasive resin bond fabric, which helps minimize loading for a lasting application.
Coated abrasive cartridge rolls are available in aluminum oxide as well as zirconium and ceramic oxide form. There is a variety of roll sizes available, from standard dimensions of 6 to 19 mm in diameter and 25 to 50 mm in length.
According to the application, cartridge rolls are available in both straight and tapered shapes. To fit the cartridge rolls, several stores also provide a cartridge roll mandrel.
