Description

Product Description of the Belt Calculator - 2945 / RB346 J-Flex Aluminium Oxide Abrasive Belts

• Recommended for grinding of non-ferrous metals (primarily aluminium), stainless steel & carbon/mild steel
• Highly adaptable to contours, curves and profiles
• J-weight backing - flexible, perfect for grinding profiled surfaces with "slack" of the belt, for example on curves and contours or for polishing applications

Structure
• Grain: Aluminium oxide
• Bonding: Resin
• Backing: J-flex cloth
• Coating: Closed

Benefits
• Excellent adaptability to contoured workpieces and radii
• Suitable for intricate profiles and small radii.
• The high strength bonding system prevents a premature abrasive grain shedding
• Improved abrasive life
• High stock removal rates

Applications
• Profil grinding with belts on automatic and off-hand machines with manual workpiece tranportation
• Manual processing with rolls and sheets for high-performance applications
• Suitable for grinding shapes, outlines, profiles and radii
• Grinding of brass, tool steel, zinc castings, aluminium alloys, stainless steel

Why Use Aluminium Oxide?

2945 / RB346 J-Flex Aluminium Oxide Abrasive Belts have an aluminium oxide grit, which is considered to be a good all-round or general purpose grain that works well on various applications.

In disc form (i.e. velcro-backed, fibre or flap discs) it is best suited to metalworking, such as aluminium and carbon/mild or stainless steel, and leaves a finer scratch pattern than other more aggressive products such as zirconia. This, in combination with its wide range of grades (generally between P36 - P400) means that it is often used prior to beginning some form of polishing process. There are also some benefits in woodworking, for example fibre discs are quite common in the floor sanding industry for the initial stages, with heavy stock removal requiring coarser grits.

Aluminium oxide is also quite common with abrasive belts, and can have specific features to improve performance on particular substrates. For example - when working on soft woods/metals it can often begin to transfer to the belt and quickly cause it to "clog" or dull, and so a more suitable material to use would be one with either a semi-open or open coat. With these there is less abrasive on the belt which leaves more space between the grains, the idea being that the loading would occur here rather than on the grit itself (the other effect of this is however that due to less abrasive being present the belt is in turn less aggressive.) In reverse a closed coat means that 100% of the surface of the belt is covered with the grain, so will take off more stock but is recommended only for hard woods and metals that are not prone to clogging. Aluminium oxide belts have either a paper or more durable cloth/polyester backing, with paper primarily being either a narrow or wide belt and most popular in woodworking, while cloth/polyester are more prominent in metalworking and available in a greater variety of sizes, again including narrow and wide but also file belts and portable sander belts.
