Plastic or rubber diaphragms are very important parts in vacuum pumps. Because the diaphragm must form a closed seal between the inner and outer chambers of the pump, an efficient pumping process is completed. The edge of the diaphragm must be flat and actinic, not rough or uneven. The laser cutting process is able to meet the requirements of the application of these materials, can provide high-quality cutting edge, improve product consistency, while reducing the edge damage may be caused by mechanical cutting diaphragm.
Laser-cut diaphragms provide good edge-cut quality while reducing the risk of damage caused by mechanical cutting.
For this application, it is required to cut a central mounting hole in a 1 mm (0.039) thick diaphragm made of stratified neoprene and Teflon. The hole diameter is 22.9 mm (0.9). (China Cutting Machine Trading Network)
The cutting process used a Synrad 80 W laser mounted on an XY platform and a 2.5-focal lens cutting head that provided a 0.1 mm (0.004) focused spot. And use CDA (clean and dry air) as an auxiliary gas, through a 0.9mm (0.0345) wide nozzle to spray at a flow rate of 100 PSI, in order to reduce the damage of the molten lens to the lens. In this way we can complete the cutting with a cutting speed of 74 mm/s (175 inches/min). The resulting cut edge is smooth and the amount of melting is small.
