## Questions & Answers

**Q: what is the diameter if the grinding wheel ?**
A: It is 3.5cm/1.38inch. 
Regards

**Q: How do i order the one with the  wv grinding wheel that includes the v-slot?**
A: Our machine is equipped  with 35 wv grinding wheel that includes the v-slot.  You can buy it if you want.

**Q: do it will work on 220v ?**
A: Works fine.

**Q: Does this work on usa 110v? Does it have a V slot for bevel?**
A: The model I received didn’t have a V-bevel. (Even though the listing picture shows one!) I had to contact the company about it. They offered a reduction in price so I didn’t have to ship it back to China. It’s useable for what I need in a retail optics shop when the lab sends lenses a little too big. This will work on a regular USA 110 plug-in.
