Advantages and use of double-disc grinders
Grinding with a double-disc grinder is an extremely efficient grinding process that uses abrasive wheels rotating in opposite directions, removing equal amounts of material from both sides of the workpiece. The result is a flat and smooth raw surface of aluminum or stainless steel, meaning double-disc grinding services can significantly reduce your pre-machining costs.
Why grind with two wheels at the same time?
The main advantage of double-disc grinding is that metal workpieces can be processed twice as fast as with conventional methods. In addition, more precise tolerances can be achieved compared to vertical or horizontal milling. Thin and large metal workpieces often bend when ground with a single-disc grinder, which is why there is a greater need for double-disc grinding in terms of efficiency and material savings.
There are also other advantages provided by double-disc grinding services, including the reduction of internal stresses in many metals. With reduced stress, the stability of the machined workpiece is improved for further processing stages. In addition, it allows labor savings (less excess chips are produced), making it very cost-effective for the production of larger quantities of semi-finished products.
How does the double grinding process work?
Since the workpiece is ground from both sides simultaneously, double-disc grinding can remove much more material and effectively halves the grinding time. In addition, the process is highly suitable for a wide range of materials – from stainless steel, high-strength alloys, to ferrous and non-ferrous metals, bronze, copper, aluminum, and more.
In a double-disc grinding machine, the discs are mounted opposite each other on a pair of spindles. Machines are available in vertical and horizontal configurations, which refer to the position of the spindles rather than the direction of grinding the workpieces.
Machine controls also allow an experienced operator to program wheel speed, feed rate, and the amount of material to be removed. In addition, a well-designed double-disc grinding machine can measure and read the thickness of each part during the grinding process, providing immediate feedback. This allows the machine to continuously adjust grinding size regardless of wheel wear.
Better final product quality
The double-disc grinding process also provides a better surface finish than many other grinding techniques by reducing or eliminating grinding patterns after the machining process.
In this way, a wide range of metal parts can be processed for various industrial sectors. In automotive components, this process is often used in the production of brake pads, bearings, and engine parts, as double-disc grinding ensures consistent parallelism between both sides of the workpiece.
Deciding whether double-disc grinding is the optimal process for your application requires a deep understanding of your specific working parameters as well as the different options for precision metal grinding.
