What are the grit-to-micron conversions?
How do I know what abrasive is best for my application?
An abrasive’s shape, hardness, and particle size really determine the effectiveness of a MicroBlasting application. Each application is unique, and abrasive selection depends on the composition of the targeted part and the application’s desired result. See our Abrasive Media Selection Guide to choose the most appropriate abrasive for your application.
Is sample parts testing available?
We welcome your sample parts for testing in our Applications Lab. Our Technical Specialists can determine the best abrasive type and size, the optimal nozzle and the necessary pressure required to efficiently process your parts.
Contact our Comco Sales Team using the form below or at 1-800-796-6626 to schedule a sample parts test. Our blog post “We Take Samples Seriously” provides an overview of the process and includes a sample test results report.
Can I reuse abrasive?
MicroBlasting is extremely efficient and precise, so it is hardly likely you will need to recycle abrasive, but it is important to know the risk involved. Unlike grit or bead blasting, a MicroBlasting system can only cycle abrasive once. Once abrasive propels through a nozzle, abrasive cannot be reclaimed and reprocessed for a second pass because:
- the blasting process causes abrasive media to break down very quickly.
- abrasive easily absorbs any moisture available in the air.
- pieces of a part’s substrate often mix in and contaminate the abrasive.
Each of these issues will bring the blasting process to a halt. Learn more in our post, “Before Recycling Abrasive…Read this.”
How do I prevent moisture contamination in the abrasive?
There are 4 key ways to keep your abrasive free of moisture:
- Store abrasive properly and always make sure bottles are tightly closed when not in use.
- Keep abrasive in a cool dry location with minimum temperature fluctuations.
- Do not leave abrasive in the blaster’s tank for extended periods of time.
- Keep the air supply dry.
