Which one CNC cutter can cut most range of foam materials ?
There are many types of foam used in building insulation and decoration industry in the world,they are open and closed-cell foams, cross-linked PE (polyethylene) foams, rubber foams, PVC foams, polyurethane,EPS,XPS etc.These materials need to be cut into sheet or 2D models in application.
Some are high density and some are low density.They are made by different raw materials.There are different ways to cut these materials,like hot wire,oscillating saw,cyclic saw,abrasive wire etc.
The answer is abrasive wire.Dry abrasive cutting is generally used for fast cutting where surface finish of the cut part is not critical and the workpiece dust is not explosive or hazardous.The application includes many different foam materials as blow:
Materials Application
Rigid polyurethane foam (RPUF) - PUR
Polyisocyanurate - PIR, polyiso, ISO
Foamed polypropylene - PP
Closed cell polyethylene foam - PE
Polyurethane foam - PU
Rebound foam, chip foam
Mineral wool - MW
Glass wool
Calcium silicate (eg. Skamol)
Rockwool
Flexible copolymer (expanded rubber, foam rubber) - EVA
Phenolic resin foam - PF
Melamine sponge, melamine resin foam
Expanded polystyrene - EPS*
Extruded polystyrene - XPS*
Foam glass, cellular glass (eg. Foamglass)
