|Project Summary||Project Information|
Glass cutting is a process that can be done on both large and small scales with many different cutting tools. Some examples include using a saw blade, a diamond coated wire, or a brass coated wire in the presence of an abrasive slurry. Each of these methods will differently impact the way the glass is cut. The saw blade will cause a significant amount of movement and vibration of the glass. The diamond coated wire does not need any other tools to assist in cutting, but the wire can create chips in the surface of the glass during cutting. The brass coated wire with the slurry will give a finer cut than the diamond; however, temperature needs to be monitored.
Glass Fab Inc. currently uses a brass coated wire with an abrasive slurry for both large and small volume glass blanks. It is a Meyer Burger DS glass cutter that uses a wire wrapped around two guide rollers. These guides have grooves that the wire will sit in and can be adjusted to create various thickness cuts in the glass to get a range of different blanks. It also uses a water cooling system in the bearings so the slurry, wire, and glass do not get too hot. There are sensors along the water cooling system that will monitor the temperatures and automatically shut off the machine if the temperature exceeds a certain value. There is a control panel on the front as well to monitor the sensors and adjust the feed rate of the wire.
This machine works very well for Glass Fab, especially for high volume parts. However, the current Meyer Burger machine draws more power than every other machine Glass Fab owns put together. It takes a while to start up and, because of the amount of power used, does not make sense to use for low volume parts. Glass Fab would like to look into creating a smaller machine, similar to the one that they currently have, that can be utilized only for low volume parts. There are existing smaller machines, but can only cut one blank at a time. The goal is to take elements of the bigger machine, essentially shrink it, and make a more energy efficient wire glass cutter. This DPL project looked into the feasibility of manufacturing a wire cutting machine that complies with the specifications from Glass Fab Inc. and resulted in the preparation of five separate project readiness packages.
Guide Rollers Project Readiness Package, Spooling System Project Readiness Package, Tensioning System Project Readiness Package, Coolant System Project Readiness Package, and Glass Feed System Project Readiness Package.
