Good morning everyone, how was the weekend? See the attached picture. This is my prototype air curtain to fit around the spindle of my HAAS VF3. The intent is to create a circular curtain of air around the spindle, to contain and or help direct the dust and debris (silicon carbide grit and dust) coming off the tool during machining. A little more detail: the green section is the top, just a simple cover; the gray section is where the compressed air is connected via 1/8" NPT, and distributed; the red section is where it concentrates the air stream and exits a 0.0025" gap between the red and gray sections. The ID of the assembly is 6.825", and the OD is 7.45"; the overall height is about 1.25". I made the first prototype out of high density butter-board to prove a concept....it works....somewhat. I'm not happy with how wide the air stream is at an 8" length. The red section is tapered on the ID as well in an effort to funnel the air...I wonder if I need a straighter section?? Any suggestions?
Thanks,
Mark
