Applications and Product Recommendations

◆ Jewelry Applications:

Grinding Step: Belting options with Expander Wheel.  Spru and parting line removal For Gold, Silver, Platinum, Palladium, Titanium, Brass, Copper, and Tungsten Carbide.

1st Step: 3M™ Ceramic Belts 953 FA grade A160 = 120 grit or 966 F 80 grit

              3M™ Flex Diamond M74 = 220 grit or 3M 675L DMFF 74 micron =220 grit

Belting products provide fast cut rates with consistent finishes.  Always select the finest grade possible based on the removal you require, remembering that finer grades may take a few seconds longer on the initial removal, but will save you minutes on your pre-polish operations. TIP – run with a moderate water flow, if using Flex Diamond belts run at 3000 rpm.  When using 675L DMFF use moderate water flow and run at 1800 rpm

2nd Step: 3M™ XR Molded Whl 1208HA = 120/240 or 3M Molded Whl 2410 HA = 240/400  

3M™ XR Molded wheels also provide another media for removing sprues, parting lines and casting clean up for those desiring a hard wheel surface, but it also provides an excellent wheel for lapping edges and small critical flat areas. .  XR wheels provide a very fine pre-polish finish pattern with much longer life then tradition Silicon Carbide papers.  XR wheels can also replace traditional hand filing steps, while retaining all you precious metal.  TIP: Run with moderate water flow and speed between 1200 & 1800 rpm

3rd Step: Optional - 3M™7 SFN Lt. Debburing Whl = 400/600 grade finish

3M™ 7 SFN Lt. Debburing Wheels provide conformability while maintaining critical tolerances providing a pre-polished finish.   Lt deburring wheels will refine scratches from either the 3M Belts or the XR Wheels very rapidly.  You may not use this step on all operations, but you will find it as a major time saver on many operations.  TIP: Run with light water flow and speed between 1500 & 1800 rpm.

4th Step: 3M™ FX Polishing Wheels 240 grade or 320 grades – Pre-polish replacing coarse grade Tripoli compound on Buff.

3M™ FX Polishing Wheels uses a conformable resin system, which results in a wheel that can follow contours, curves and unique part geometries, while providing uniform finishes.  Unlike Tripoli Compound you can run the 3M™ FX wheel with water, reducing heat, eliminating sonic clean-up, and complete retention of precious metal. Choose either a 240 or 320 grade depending on the work piece and the products used during steps 1-2 or 3.  We have found a number of customers who use a FX 240 directly following a 3M™ 675L 74 micron DMFF belt. Consult with a 3M™ Representative if you have any questions.  TIP: Run with light water and at 1200 to 1500 rpm.

5th Step: 3M™FX Polishing Wheels 600 grade or 800 grades – Pre- polish replacing medium grade Tripoli compound on Buff.

FX 600 & 800 grades provide you with another option based on your work piece.  Remember this option is right in line with your finishing system and does not require moving to another station, just a few seconds on either of these grades will reduce you final polish step.  TIP: Run with light water and run between 1200 to 1500 rpm.

6th Step: 3M™FX Polishing wheels 1500 or 3000 – Pre-polish replacing white diamond or other fine grade Tripoli compounds.

FX 1500 & 3000 grades provide the last pre-polish finish.  Depending on the precious metal or semi-precious metal being polished you will find that this final FX wheel step will reduce your final Rouge Buff step significantly.  3M™ FX Wheels will provide the time and cost savings you are look for. TIP: Run with light water and between 1200 to 1500 rpm.

◆ Lapping Disc:

Both the MAX30 can run a 5” or 6” disc on the right side, with or without water.  You will find this convenient feature will allow you to flat lap edges on virtually any piece of jewelry or art object.   3M™ provides a large selection of lapping discs to meet your specific work piece requirements.  Refer to the 3M.com/creativearts website for these disc products.
