With smaller parts, anything you can do to aid vacuum hold-down can help your productivity and outcomes. This is a good option if you are cutting parts that are typically 12 inches by 12 inches. Having small holes and creating vacuum in more spots under the spoilboard makes vacuum consistent all the way to the corners.Īdditional techniques for optimizing vacuumĮdge Sealing: Since vacuum can leak out from the edges of the spoilboard, you can also consider sealing the side edges of a new board with tape, paint or a special form of sprayed shellac that dries in a couple of minutes. But the vacuum created through big holes often results in vacuum variation in the corners of the table. There are machines that have fewer, larger holes for creating vacuum. With repetitive flycutting, a spoilboard typically needs to be replaced with a new one after 20 or 30 days.īuying Tip: Look for a CNC router with a phenolic table with smaller holes. This “maintenance flycutting” may need to be done twice a day, especially if you are working with small pieces. Fortunately, when you have an automated machine, it picks up the right tool for flycutting and handles the job for you quickly and easily. As they become more numerous, these grooves can compromise the table’s perfectly flat surface, and the vacuum’s ability to hold down the next run of parts.Īt this point, optimizing vacuum requires a second step: flycutting your spoilboard again. But grooves often left from 0.1mm cuts on the spoilboard can be a problem, especially when you have different runs with vastly different nesting. Programming the router to cut 0.1mm in depth is what it takes for parts to be cut and divided correctly. Note 2: Make sure the machine you choose has a pre-setter large enough to measure the flycutter (for example, 130mm) Note 1: Running the flycutter too slowly can reduce your productivity and may prematurely wear the blade insert When you are working with nesting cells, bolting the spoilboard to the table ensures that the sweeping arm that pushes the parts forward can’t displace it. This flycutting makes the board open and porous enough to accept the vacuum. The first step in optimizing vacuum is to make a 0.5mm flycut on both sides of the raw MDF. But raw MDF comes sealed, preventing vacuum from passing through it. An MDF spoilboard is instrumental in creating a table that is perfectly flat and in providing the best cutting surface. The integrity of the phenolic table is protected by a spoilboard made of MDF, typically with a 3/4-inch depth. CNC routers can have 2 to 8+ zones to help optimize and isolate vacuum. Instead of creating suction where it is wasted, the machine concentrates the full power of the vacuum pump exactly where it is needed to maximize hold-down effectiveness. So if you have a 5-foot by 10-foot table, but you are working with a 4-foot by 8-foot piece, the controller keeps the vacuum within that 4-foot by 8-foot section of the table. By accessing holes in the phenolic surface and the grooves between them, the vacuum pump under the machine can spread vacuum suction evenly around the table or through specified zones. A phenolic table’s matrix is essentially a rubber gasket that can be used to isolate the zones of the table you need to use. Optimizing vacuum starts with understanding the advantages of having a router with a phenolic table. Optimizing machine performance depends on knowing what it takes for vacuum-pumped air to permeate your machine’s table and the MDF spoilboard that protects it. Dependable hold-down capability is crucial to all jobs, but especially those that involve cutting smaller parts. Similar to a few other clipboard managers, Maccy also allows you to exclude certain apps from being recorded, so you can rest assured that it won’t record your passwords or any other sensitive information.Manufacturers that work with nesting CNC routers depend on optimal vacuum to hold down their parts firmly and consistently. Not that that, you get the ability to paste clippings (with or without formatting), pin items you’d need frequently, and clear your history at once using keyboard shortcuts, as well. Maccy uses keyboard shortcuts for most of its operations, which lets you select the clippings you want to use quickly and easily. It does the job of keeping your copy history at hand so you can select the one you want to use and paste it across different apps and services. Maccy is an open-source and lightweight Mac clipboard manager. Moreover, Anybuffer also has a powerful search feature, which lets you quickly find your saved clippings and smart shelves, allowing you to keep everything organized and access it from anywhere.
