OK, its time to get a CNC router to boost production, but I need advice on how much spindle HP I will need to get good production rates without overdoing it on the cost for more HP.
I work with 1/2" thick HPDE plastic and want to be able to cut thru in one pass and not repeated passes. Basically I need to route plastic flange disks 6.5" to 9" dia with bolt holes.
I'm talking to a router manufacturer who has a machine with a 7.5 HP spindle, and 11 HP is also available as an option. He isn't familiar with cutting HDPE so he can't give me advice on this issue. Is 7.5 HP enough to route in one pass in 1/2" HDPE, or do is the 11 HP needed?
