"The double disc grinding development process for composite strips can be an arduous task. Prior to using the DD-7, one of the largest challenges our customers had with grinding this type of material and shape was the limitations of belt sanding machines which require multiple passes on each side, requiring operator handling and take up a lot ...
Double disc grinding is the process of grinding equal amounts of material off both sides of the part at the same time. This process works especially well for non-magnetic materials that cannot easily be blanchard or surface ground. All knife blades must be double disc ground prior to bevel grinding. The reason for this is that we need to start with an extremely flat and parallel blank.

This process works especially well for non-magnetic materials that cannot easily be blanchard or surface ground. All knife blades must be double disc ground prior to bevel grinding.
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 reduces ...
The machine's design features, in combination with the exclusive rotary plunge grinding process, provide better parallelism, flatness, size control and squareness compared to conventional double disc grinding processes. The rotary plunge process also results in improved grinding wheel and diamond dresser life.
The DD-7 is one of the most compact double disc grinding machines on the market. Designed for grinding small diameter components, it accurately controls their length and perpendicularity. The machine is capable of grinding many high-performance parts for a wide range of industries from medical and aerospace to automotive. The DD-7 can be configured in three fixturing …
relatively huge amount of power used in the disc grinding process generates heat that must be effectively dissipated. 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 to the ability to attain flatness tolerances that would ...
DOUBLE DISC GRINDING. Our service is opposed double disc grinding, which is a method of using two opposed abrasive disc wheels to remove stock simultaneously from both sides of parts, which have parallel faces. This process can combine heavy stock removal with precision finishing in the same operation to produce a high degree of flatness ...
Double-disc grinding is an extremely efficient grinding process that uses abrasive wheels that oppose one another, grinding and removing equal amounts of stock from both sides of a blank. The result is a flat aluminum or stainless steel machine-ready blank with parallel tolerances to .0005" and finishes to 16 Ra. At DIX Metals, our double-disc grinding …
Double disc grinding makes it possible to grind opposite surfaces of the part at the same time, potentially reducing overall grinding cycle time. This style of grinding also makes it much easier for a shop to maintain tight tolerances on flatness or parallelism between surfaces, as this footage from TCI Precision Metals shows.

The double-disk process grinds both sides at the same time for economical high volume production. Double-disk grinding works well with all steel alloys, but unlike blanchard grinding or conventional surface grinding, double-disk does not employ a magnetic chuck so non-ferrous materials like aluminum, copper alloys, and stainless steel can be ...
I worked at a double disc grinding job shop for 15 years, and ground a lot of problem parts. If you find that there is plenty of material to remove another thing to look at is the area to be ground. Because the wheels are typically the same spec on each side the stock removal will only be even if the surface area is the same.
Double Disk Grinding. 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. They are then …
