Hello, currently have both Aluminum Oxide & Silicon Carbide PSA 4" pads that we use to polish Glass Die facets. Can you advise on advantages of one type over another? We use these for optical polish after grind.

For a particular abrasive "grit" size, silicon carbide particles are harder and sharper than aluminum oxide. SC will cut a surface faster, but AO will typically provide a smoother finish.

Good morning, Is this something you are able to provide? Polishing Film – Alumina Oxide (AO) and Diamond (5.5” x 5.5” sheets) **5.0um AO Foam-Backed Film Part# 0700-2663 We are looking to purchase very large qty. Thank you Laura F&M Micro Products

We can supply these film types, but only in 5", 4", and 2" diameters for use with Krell automated polishers.

Do any of these machines have to be calibrated? If so, can you provide information on how often and who calibrates the machines. Thank you

For your application and system set-up, there is no need for routine calibration. You can confirm system alignment using the videoscope inspection system and measurement software. If polish angles deviate from your target specifications, the workholder provides the means for in-house adjustment.

We are looking for a desktop fiber polishing machine capable of polishing form about 300µm up to 2000 µm fibers. Ideally fiber advancement should not rely on gravity. Only 0° angle polish. Are there any demo units available in Germany/Europe?

Krell offers several polishing systems for bare fiber applications. Our local representative will be reaching out to you with more information and a quotation.

Hello, We currently have a Nova polishing system in our lab, but we do not have the adapters to enable bare fiber polishing. I was wondering if it's possible to purchase just the adapters for bare fiber polishing relevant to our application to adapt our current system. Thanks!

Yes, we offer bare fiber adapters for all Krell polishing machines. We will send you a quotation.
