coolant/lubricant for machining acrylic?

OK, not really metal-related, but I need to machine some acrylic stock and was wondering what a good coolant or lubricant would be? I've read that 30% liquid Ivory soap-70% water works, but are there any others to consider? Thanks, Dave Dave Standard coolants work well, maybe a little weaker than usual (1-3%) or a Cold air gun. The important thing is to keep the heat out of the workpiece. Use very sharp tools. If using carbide inserts, high positive ground and polished edges are best. |
