For superior rigidity, our line of vertical double disc grinding machines is built on a three-block cast iron box type framing structure. This ensures our VDD machines have exceptional stiffness and robustness. We offer both conventional and super abrasive grinding wheel (CBN & diamond) options. As a result, you get reduced cycle time, …
Double-disc grinders hold remarkable standards for parallelism, flatness and size in high-volume production environments. Because the machine grinds two sides of the part at the same time, you'll save on handling costs and grind time. Double-disc grinders boast high productivity rates, with streams of parts flowing rapidly through the machines.
Double-Disc grinding ability is to extract equal parts of material from opposite sides of a workpiece that results in applying a reduced amount of internal stress to the materials. Furthermore, it enhances stability during machining operations, leading to higher accuracy and parallelism. ... This process often results in a more accurate …
"Double disc grinding is an abrasive machining process that removes material from two sides of a part simultaneously. In a typical double disc grinding machine, the grinding discs are side-mounted on a pair of opposed spindles. Because the process grinds both sides at the same time, it offers a high degree of accuracy and parallelism and ...
Simultaneously grinding two sides of the workpiece, our double disk grinding process removes equal amounts of material from both sides in one operation. This not only …
Double disc grinding has a couple of inherent advantages. Since the part is passed between two abrasive discs, the stresses on the part are equal on both sides. This leads …
Simultaneously grinding two sides of the workpiece, our double disk grinding process removes equal amounts of material from both sides in one operation. This not only ensures greater control of dimensional tolerances, flatness, and parallelism, but also relieves internal stress relief and improves part stability during secondary operations.
Double-disk grinding. Considered one of the "classic" grinding processes, double-disk grinding is performed when both sides of a workpiece must be ground so that both …
A print ad from 1959 touts a Gardner double disc grinder as the right choice when you can't get it done with a "single disc surface grinder." Some 60 years later, you'll still find much more sophisticated versions of Frederick Gardner's twentieth century invention churning out thousands of parts daily. Found in factories worldwide, double … Continue …
time to enter the new grinder market. Sensing a need for a state-of-the-art machine offered at an affordable price, GCH proudly introduces its new double disc grinder. With a combined 150+ years of grinding experience, the GCH Machinery team offers a robust double disc grinder that is precise, reliable and accurate
Advantages of Double Disc Grinding . ... We meet diverse requirements and can process virtually any material including ferrous and non-ferrous metals, plastics, composites and even rubber parts. We can maintain a thickness tolerance of .0002" while holding the surfaces parallel within .0001". Hyproplapping technology allows us to achieve ...
Abstract and Figures. Unlike most double-disc grinding processes, which use forced workpiece rotation, some double-disc processes rely on workpiece self-rotation driven by non-uniform shear forces ...
Double-disk grinding . Considered one of the "classic" grinding processes, double-disk grinding is performed when both sides of a workpiece must be ground so that both surfaces are exactly plane and parallel. The workpiece is not fixed for this process. Instead, it is loosely placed in the "nest" of the workpiece carrier. ...
Simultaneous double-disk grinding is a novel and powerful technology for silicon wafer planarization as required for the latest and upcoming future microelectronic device design rules. DDG uses two opposite grinding wheels, which simultaneously flatten both sides of the free-floating wafer between them in a single process step.
Double disk grinding is a fast, economical finishing process. Work parts are passed quickly through two rotating vertical abrasive wheels which can remove a large amount of material. Grinding is frequently used as part of a two-step process. Parts first go through a grinding process to quickly achieve approximate tolerances.
Process variations: plunge-cut, through-feed and oscillation grinding ; MACHINING PRINCIPLE: DOUBLE-DISC GRINDING Work pieces are machined on the double-disc grinding machine using a through-feed, plunge-cut or oscillation process, depending on the respective requirements. The compact and rigid machine configuration ensures the …
Double Disc grinding simultaneously grinds two sides of material using two opposing abrasive wheels. It is a very effective grinding technique for obtaining surface smoothness, flatness, and parallelism with tight tolerances in the appropriate applications. This grinding technique can remove more material, cutting the grinding time in half.
The double-disc grinding process is consolidating its position in automotive applications but is moving into other industries. Double-disc grinders are now easier to …
