Cast Iron Conditioning Rings wear naturally as part of the lapping process. Replacements are available to fit most flat lapping machine models. Available as solid or serrated
Custom built diamond plated conditioning rings available in a variety of Grit sizes, including Grit 60 and Grit 120
Plastic faced and ceramic faced conditioning rings are also available. These are used for polishing rather than lapping operations.

Cleaning conditioning rings using Kemet ultrasonic cleaners
Occasionally with the conditioning rings it’s important to give them a clean especially when they start to become contaminated or blocked and if you are changing grades from a coarse grade to a fine grade.
So in between the grooves we have contamination and if a coarse grade is used it will be embedded in the surface, so we are going to show you the best way of cleaning these and getting back to a fresh clean control ring.
What we have here is a ultrasonic cleaner system. In this unit we use water with a concentrated chemical, in this instance we are using Kemet Type A, which is an alkaline detergent which is good for general use on all types of steels and ferrous materials, the concentration in the system is about 12-15% and the temperature is 50-55°C.
So put the control ring into the system with the slots facing downwards, we are going to give this a process for 10 minutes and then turn the ring over for another 10 minutes. Sometimes it is a good idea to move the basket up and down to loosen the contamination and fluid. After a short period, you will see most of the contamination has cleared, but leave in for the full 10 minutes. For a badly contaminated control ring use a brush to remove any loose contamination, and then put the control ring back in but the other side up and start the process again.
After the second process the ring should be clean, next stage is to rinse. It is important to rinse the ring after the process, what rinsing does is removing the concentrated detergent and any loose contamination and will also give you a chance to inspect it is completely clean. If you use warm water, it will help to speed up the drying process.
One important thing to check is the chamfer on the outside, this will gradually wear away, once the chamfer disappears, it is important to re-machine on roughly about 3mm by 45 degrees. You can also look at the condition of the ring width ways because that will very gradually wear down, when it gets down to the point that the grooves start to disappear, that’s the time to replace the ring because not only has it lost its effectiveness but also a lot of its weight for conditioning the plate.
