Cutting (turning, milling, drilling, sawing): only traditional metalworking – or in certain cases, woodworking tools – carbon steel, rapid steel, hard metal, diamond can be used only in sharp design. Cooling is recommended, which allows high cutting rates, e. g. v = 200 –400 m/min for turning and milling, v = 50 –100 m/min for drilling. Sharp corners, slottings should be avoided, the value of minimal inlet radius and champfer is min. 1–2 mm.
Vacuum and thermoforming, adhesive boding, welding: feasible.
It offers an optimal combination of the described product characteristics, in a size selection corresponding to the traditionally widespread areas of application.
PMMA sheets coated with nano-metal particles having Esd surface. There two grades: bending and not bending versions for thermoforming.
