What Is Grinding Disc?

Grinding disc is a kind of resin abrasive tool with special fiber fabric as reinforcement material, contain abrasive grains and layers of fiberglass bonded into a wheel shape by another substance.The abrasive grains act as grinding tools, removing material from a workpiece to shape and refine it.and is widely used in grinding and rust removal of various metal and non-metal materials, which is fast and economical.
Several types of grinding wheels are available, so when a facility is choosing a wheel, it's essential to consider the specifications of contrasting styles and how well they can handle different environments and operational challenges. In this guide to grinding wheels, we discuss working theory of grinding disc, as well as video about how to operation and specific applications.
When using grinding disc, pay attention to wear protective measures and check for correct installation(Align flanges correctly and ensure the guard is fitted) and do not exceed the maximum speed

How It Make?

Working Theory Of Grinding Disc

Angle grinders use high-speed rotation to grind, cut, remove rust, and polish metal components. Grinding disc are suitable for Grinding/Polishing/Deburring/Chamfering/Trimming... Water should not be used during operation.

General Fabrication

In general metal fabrication, 6mm thickness are common choices.greater precision, less heat generation, and fewer burrs that will require removal before welding. The choice of grain will likely depend on the material composition of the workpiece — higher-performing grains for structural steel and difficult-to-cut metals, contaminant-free discs for stainless steel.

Pipe Fabrication

Outstanding grinding discs for angle grinder for stock removal rate and easy to use. No clogging, no chattering.It’s also advisable to choose the thinnest disc possible to minimize heat and friction and to use a type 27 disc for a deeper cut unless the application imposes a particular constraint. For larger pipe often found on the pipeline, a depressed-center disc provides added clearance when working at a constrained angle, and 6mm thickness is ideal for cutting applications in fabrication yards or on the right of way for field repairs.

Shipbuilding

When an operator is working on the confined, hard-to-access spaces of a ship, making a grinding disc last as long as possible is often a priority. For this reason, the operator will often want to choose a harder, potentially longer-lasting disc like DELUN Ceramic. However, when operators must use air tools whose hoses have stretched over long distances to access difficult areas of the ship, the tools may be underpowered. In this case, discs with a soft bond will be ideal because they make it easier to maintain a fast cut. In shipbuilding, the work material often influences the grinding disc selection. When working with aluminum, an operator may want to select a grinding disc that will not load or gum up, like DELUN Aluminum.

Welding Preparation

Preparing for welding typically involves exact metal grinding. With a basic cut-off operation, precision is not critical, but with complex work or repairs that need to preserve the initial aesthetic qualities of the material, precision can save time and money.

Railways

Modern railways use hard-to-grinding alloy steels, so a high-performance grinding disc is necessary for high-speed gas saws. A self-sharpening zirconia alumina grain that retains a high grinding performance throughout the life of the wheel offers excellent performance.

Construction

Building and construction sites feature a wide variety of metal Grinding applications. Operators often look for a disc that can do it all, structural and galvanized steel, sheet metal, structural tubing and other ferrous metals.Many times, an aluminum oxide wheel provides the right mix of versatility, performance, and price. The DELUN AO line offers depressed-center grinding wheels in various sizes for die and right angle grinders.
