How fast does the CNC cutting machine need to cut 12 thick plates?

The cutting speed of the sheet is not directly related to the thickness of the sheet. In fact, the cutting thickness of the sheet is related to the oxygen pressure during cutting. If the oxygen pressure is relatively small, the thick plate will be cut continuously.

General cutting thickness is 5~20mm, oxygen pressure is 0.25MPa, acetylene pressure is 0.02MPa, and cutting speed is 500~600mm/min.

I can give approximately the diameter of each cutting nozzle and the thickness of the sheet , The relationship table between oxygen pressure (but all experience values u200bu200bare for reference only)

Cutting nozzle diameter 1mm

Sheet thickness 4mm Cutting oxygen pressure 0.2 Cutting speed 450~500mm/ min

Sheet thickness 5mm Cutting oxygen pressure 0.3 Cutting speed 400~800mm/min

Sheet thickness 10mm Cutting oxygen pressure 0.35 Cutting speed 340~450mm/min

Sheet thickness 15mm, cutting oxygen pressure 0.375, cutting speed 300~375mm/min

Sheet thickness 20mm, cutting oxygen pressure 0.4, cutting speed 260~350mm/min

In short, the cutting thickness follows , Cutting oxygen pressure has the greatest relationship

Basically, flame cutting is not checked much, plasma cutting speed is relatively fast
