cooling | | Hi,
I am new in woodworking but I made a CNC and experimenting with it. It is cool but top of my router bit gets burned. I am woodworking pine with low router speed and velocity 250 mm/min (sorry, no inches this time) which is almost maximum speed my machine can take. Still the top burns. Before the wood got burned too but after increasing velocity it does not happen any more. Only top of the router bit gets burned. The problem is heating I believe. How to avoid it? Should I use some liquid cooler like water or...? |
