In CNC milling can laser, in a minute, practically replace run of the mill apparatus head for milling larger items? If not what?
CNC Milling Machines need traditional heads, and cutter operation. especially for large jobs.
However, lasers are great for smaller job, and touch-up operations. As of this point, nothing is out-their to replace a normally(Traditional) CNC Head.
Lasers will not replace standard milling tools. The problem next to lasers is that they keep going until they hit something.
If your part have two pieces separated by a gap, and you needed to machine a hole surrounded by one of the pieces, a drill bit would do this easily without touching the second piece.
However, a laser would get going cutting through the first piece, and once the hole was made, it would without beating about the bush begin cutting through the second piece if the shaft was not turned off without beating about the bush. At the least, you'd get some scarring on the second piece.
