3M™ Flexible Diamond Sheet 6451J features micron-graded diamond particles which are metal bonded to a low-stretch backing. Three available open dot patterns are available for various stock removal and finishing requirements. Sheet 6451J is designed for use on hard-to-grind materials.
|3M ID||Backing Type||Description|
|6003J||VF||Very flexible backing; available in rolls only.|
|6450J||C||More flexible than Type G. Best construction for short belts. Suitable for slack belt operations, such as glass seaming, hot roll finishing. Weldlok splice.|
|6451J||G||Low stretch, for use with contact wheels. Suitable for roll grinding. Use for roll finishing when closer caliper splice is required. Weldlok splice.|
|6454J||V2S||Most flexible backing. Used for lighter duty applications, such as blending and finishing contours.|
|6456J||YFB||Least amount of stretch of all backings. Excellent water resistance. Very close to zero caliper splice, for centerless finishing where caliper control is important. Use in roll form for superfinishing.|
|6457J||VF||Very flexible backing with moderate stretch. Ideal for use on contoured surfaces. Weldlok splice.|
Our Open Dot Pattern: What Does it Mean?
The open dot pattern on each 3M™ Flexible Diamond abrasive product means that the diamond mineral particles are adhered to the backing in a series of small dots. This is designed to provide aggressive cutting action while also allowing consistent space for evacuation of stock particles during use, helping reduce loading and prolonging the life of the abrasive surface without sacrificing cut rates.
3M™ Flexible Diamond Belt 6451J is available in three open dot patterns for a range of uses. Pattern 18 is a small dot pattern equating to 25 pellets per inch our B2 Pattern has medium dots with 17 pellets per inch, and is designed to deliver an aggressive cutting action with improved coolant flow and increased swarf removal. Pattern 21 is offered for grades 250µ and 300µ only. It utilizes larger dots to assist in applications where high stock removal is required and loading is an issue. Generally, the smaller dot patterns will be the least aggressive and produce finer finishes, whereas the larger dot patterns will be more aggressive for stock removal.
