Using Diamond Suspensions for Precision Finishing

[LeonidF39263]

In fine grinding and polishing operations, especially on hard and brittle materials, choosing the right diamond suspensions can significantly impact surface finish quality, scratch control, and cycle time. Consistent particle size and a stable carrier fluid help maintain uniform cutting action and avoid embedding or gouging at the final stages.

For reference on different suspension grades and how they’re intended to be used, this overview is helpful:

For those here who integrate diamond suspensions into their workflows:

• What grit ranges and suspension concentrations give you the best balance of removal rate and surface integrity?

• Do you prefer delivering the suspension wet, misted, or via a recirculating system?

• Any pad/lap combinations that consistently improve results in high-precision applications?

Curious to hear real-world setups and parameter choices for optimal finishing performance.

Hello, this is a relevant topic for the work I did on a sample intended for analysis. I would like to point out that I am an amateur. I would appreciate corrections from professionals. I was curious about the effect of these diamond pastes that I bought from a Chinese supplier, with a grit size ranging from 1000 to 80000. At first, I used diamond-coated wheels with a gradation of 1000 to 2500, followed by a felt disc, which I covered with a little paste, starting from 3000 to 30000. Of course, I rinsed the surface of the felt wheel with warm water between changes. I am posting photos of the surface I polished.
