Drag Engraver

CNC Drag Engraver – Magnetically Retained

About

When drag engraving our spindle squares there was an operator error moving the diamond off the edge of the stock and back over again. This caused the diamond to break free from the tool. Of course this was also the last tip. The tips were $25 and required the entire tool to be disassembled. You had to custom order or make one of the tips from scratch. The wait time would be another week and this wasn’t acceptable. You couldn’t run down to your ace warehouse and pick up what you needed. There had to be a better way that was more economical, easier, available and worked on our smaller machines that didn’t the ability to use large collets.
