The part of the CNC wood router which performs the actual cutting is called spindle. To classify the spindle, horse power (in English units) and watts (SI units) are used. Spindles rotate for about 8000 to 30,000 rpm or revolutions per minute. It could cut materials ranging from soft to hard materials like plastic and metals. CNC Woodworking Random Tips These days, as in all the other fields of interest, CNC woodworking still has some areas where manufacturers, woodworking professionals, hobbyists and amateurs may only have some scant knowledge of, or perhaps may not have tried them, or have only heard about them. The following are a few random tips, information bits, techniques and other aspects in CNC woodworking (routing, machining, drilling, and others) that had only been uncovered recently. Where precise-fitting assemblies (dados, rabbets, inlays, arches, bas relief carvings) used to be difficult to produce using the traditional tools, CNC technology did all of them quickly and efficiently. Templates and versions Knock-down furniture pieces are notorious for being very time-consuming in designing and getting the parts together perfectly. Dual zone machine In the nesting environment, the new ability to have a dual zone machine that can handle full sheets while providing a load/unload time of zero had drastically changed the throughput of nested-based machines. CNC machines are now flexible enough to perform nearly any machining operation because of the 4- and 5-axis capability and the proper tooling. These can include metalworking and spinning, glass working and wood turning. CNC Laser cutters Programmed through specially-designed computer files, CNC laser cutters are designed to cut materials like metals. Generally, cutting using laser is more precise and much finer than any other mechanical cutting tools. Standard manufacturing concepts stated that machines should be operating at all times for maximum efficiency. That mindset was changed when the router they purchased became operational and produced in a few hours what their employees took two days to make. Commitment and patience, and not just a leap of faith, are certainly needed for a small shop owner when trying to upgrade his business.
