Hi
Some bloke came into my shop the other day with a piece of vinyl flooring which he was supplying to a local bus manufacturer, asking if I could cut various shapes for placement onto the bus floors -ie disabled sign, exit, entry, etc. The idea was to cut out, remove the shape and cut an insert to fit.
Easy peasy I thought. I Put his sample on the bot, made a toolpath to cut a disabled negative and positive, and fired up the router.
As soon as the bit touched the surface, sparks started to fly. The bit ( an expensive 10mm spiral downcut) moved about 3 inches before I could hit the stop button.
I took out the bit, and saw there was a groove in it about 2mm from the tip, about 1mm deep. I looked closer at the flooring, and noticed it contained tiny specs of glittery substance I had not seen before. I assume this is carbide or something superhard to prevent wear and tear on the floor.
This is potentially a big ongoing order. Can anyone think of any way round this, or is it something I have to turn away?
