My company is looking at possibly using a CNC machine for drilling holes in an aluminum extrusion. There are multiple profiles available, but all have 0.07" wall thickness. All will use holes between 1/8" and 1/2" diameter. We know there are metal working machines out there in the $50K+ cost range, but we were wondering if there are lower cost options for just drilling? Looking for 1st hand reports of anyone using some of the cnc routers in the $15k range. Any victories or failures anyone care to share about? Specific machines tried and outcomes?
