Questions & Answers
5 questions

I have a large enough compressor but PSC-600 bogs down from time-to-time. What can I do to improve the operation?

Since you may have multiple pieces of equipment connected to the compressed airline, you may be short of air flow available from your compressor.

What is different between wet grinders on the market and the PSC-600?

Most of the wet grinders have been built with alteration of a common pneumatic high-speed angle grinder designed for dry metal applications with an exterior water feed. Even though you may find one with center water feed system, water would spray towards the outside of the blade only and water wouldn’t ever cool the other side of the blade. The PSC-600 is designed from scratch as an industrial wet cutting tool for the stone industries. With this said, the Alpha wet cutter is built with more than 30 years of experience producing wet polishers and the voices from stone fabricators.

Can I use PSC-600 for grinding application?

Yes. use either as a wet stone cutter or wet stone grinder since it has a very unique center water feed system. To use as a grinder, replace the Inner Flange designed for cutting with the one designed for grinding which will send all the water to the grinding edge, instead of dividing it onto the two sides of the grinding cup wheel. Note: Due to the spindle thread size, any grinding wheel with a pre-threaded 5/8”-11 arbor will not fit on PSC-600; so you need to use one with a 7/8” straight arbor for sanding and grinding.

Which product does Alpha recommend for sanding and grinding?

We recommends using a 5” Vexcel Rigid Disc 25 grit (VDR5025) for heavy grinding applications and a 35 grit (VDR5035) for general shaping applications. We also recommend a 5” Spike Disc 35 grit (VCS5035) for resin net removal from the back sides of stones. In both cases, you can enjoy fast material removal with much less noise and vibration as compared with sintered bond grinding wheels.

Does Alpha offer any flexible discs to complete profiling on a round over edge?

Alpha recommends a 5” VFlex Flexible Sanding Disc (VDF50xx series) to shape up the profile of round over edges or to clean up the internal oval rim of a vanity. Select from 35 grit, 50 grit or 80 grit to complete this task.
