Make various signs on your cnc machine, wood, metal, acrylic and more.
Sign Making CNC Machines
Do you want to quickly create an extraordinary sign as opposed to printing a sketch with a plotter? Welcome to the world of CNC routers! In this universe, any design or logo you create on a computer screen will look even better when you hold the final product in your hands. And, you can count on the sign to also be exceptionally accurate to the smallest degree.
For hundreds of years, hand carved wooden signs were the only option in the sign making industry for craftsmen to achieve both precise lettering and the desired aesthetic. But within the last decade, sign foams, acrylics and aluminum composites began emerging as a cheaper alternative for sign makers. Wooden sign making had become an expensive, labor intensive time consuming process.
Today, modern CNC routers create endless opportunities for sign laser cutting with the most intricate designs.
The technology converts a one-dimensional graphic sketch into a three-dimensional model in a process that’s both fast and furiously accurate.
The CNC router machine cuts in three directions referred to as the X, Y and Z axes. The X-axis runs left-to-right while the Y-axis, usually the longest, runs front-to-back on the panel of material being processed. The Z-axis runs up and down giving depth to the final product. Manipulating cuts in these three dimensions result in extraordinary signs that surpass the intricacy of craftsmanship that can be achieved by hand.
CNC Routing includes the following four basic components:
1. Computerized Controller
The CNC machine is controlled by a computer which serves as the brains of the device. Computer numerical control (CNC) technology converts computer-assisted designs (CAD) into machine commands. In short, the computer tells the machine how to move and cut in order to execute a design by using G-code.
The high speed spindle holds the specific drill bit or cutting tool. This component does the actual cutting on the wood material selected for the sign. The spindle rotates at speeds ranging from 9,000 to 24,000 RPM. Variable speeds are important when a craftsman routers wood in order to accommodate various wood species, thicknesses, and quality.
3. Cutting Bed
The cutting bed supports and secures the piece of wood being cut. Think of it as a work table minus the rickety saw horse supports. Most wood CNC routers use either a T-slot or vacuum table cutting bed for securing the wood for panel processing. A T-slot system uses bolts and clamps to secure the wood to the bed. A vacuum table uses vacuum pumps to hold or suction the wood to a spoil board.
4. Linear Drive System
Each axis of a table CNC router is controlled by a linear drive system which actually moves the spindle. The drive system may be a motor and linear bearing system, ball screws, or rack and pinion configuration depending on the design.
CNC machines offer a wide variety of cutting options for today’s craftsman when making wood signs. For example, you can:
• Engrave letters into the wood
• Cut letters out of wood resulting in dimensional letters that can be assembled in different layouts
• Inverse cut letters so that the letters are below the surface of the sign
CNC routers cut any type of wood with equal simplicity. Depending on the grain and absorbency of the material selected, the craftsman can choose to finish the sign with stain, an oil product, or long lasting paint.
