Most woodworkers define the value of a woodworking machine by the speed and intricacy with which it shapes wood. In the early 1970s, the invention of computer numerically controlled (CNC) woodworking machines took these values to a new level. Unlike traditional woodworking machines, which require varying degrees of manual control, CNC machines made it possible to automate the woodworking process. Instead of controlling a machine as it performs woodwork, it could be programmed to perform the desired function. It could also produce more intricate woodwork than standard woodworking machinery, and could produce it at a faster rate.
Wood CNC machinesare best known for their remarkable cutting accuracy, which results from two factors: cutting on a Cartesian coordinate system that facilitates three-dimensional motion control, and the use of more than one cutter head. The end result is the ability to cut intricate, three-dimensional designs that would otherwise need to be carved by hand. The cutting intricacy of CNC machinery makes it appealing to hobbyist and professional woodworkers alike. But it benefits the latter in another way as well: excellent repeatability across large production runs.
Manual routers present the problem of waste pieces due to human error. Over time, this problem can lead to other problems: lost revenue due to waste pieces, and lost production time due to rework. CNC machinery eliminates the human error that results from the manual operation of woodworking machinery – a lucrative benefit for companies that produce a high volume of woodwork.
Wood CNC machinesare praised for their superb cutting accuracy. But their ability to meet increased production demand is just as impressive. Because the work they perform is computer-controlled, their economy of motion and cutting speed eliminate wasted production time. When the right size of cutting table is present, even large pieces such as stair risers can be produced expediently.
Woodworkers often remark that a CNC machine can produce as much work as multiple manually controlled machines could produce in the same period of time, which is true. When two or more standard machines are replaced with a CNC machine, workspace can increase, and the ability to decrease staff by employing fewer machine operators becomes a reality.
Buying a CNC Machine
Industrial grade CNC contraptions are not inexpensive. But the collateral benefits that they bring can make them more cost effective over time than manual machines. The cost of a new CNC machine causes many woodworkers to consider buying it used – a viable option when it is purchased from a professional seller of used woodworking machinery. In many cases, a used CNC machine costs 50% less than it did when new and still offers top performance and dependable operation for decades more.
CNCmachinery has reshaped the professional woodworking process considerably. Intricate cutting jobs that were once impossible with industrial machinery are now possible, and the ability to program large production runs that are free of human error is possible as well. To learn more about the benefits of replacing a manual woodworking machine with a CNC machine, contact a seller of new and used CNC machines.
