Inquiry (采购产品): Air Abrasive unit complete, etc. We are working on a design for cutting matching grooves on the outside & inside of a pair of quartz, alumina or other refractory ceramic material tubes. This will probably require right angle tip, and a long neck. Please include pricing. Can't buy if we don't know how much it's going to be! (I have used your older units in the past for similar work - loved it.) **** Hidden Message ***** Z Stersky 556 Sunnymount Ave Sunnyvale, CA 94087 USA Company: Zoltan Research Title: Director E-mail: zs@zoltan.com **** Hidden Message ***** zs@zoltan.com
