Material Prep
The project begins with material preparation. The sign board, weighing 15 pounds, would be composed of a high-density composite, chosen for its durability, weather resistance, and smooth surface—ideal for both indoor and outdoor applications. Before cutting, carefully clamp and level the board to ensure stability during machining. Even slight movement during the milling process can lead to misalignment or inconsistent depth, which is unacceptable in professional signage.
Using a multi-axis CNC router, program the machine to follow a detailed vector path outlining the customer’s design. Speed and feed rates were optimized for both efficiency and surface finish, taking into account the material’s density and the required precision.
The Process
Throughout the process, pay close attention to chip evacuation and cooling. With heavier boards like this, heat buildup can lead to warping or tool wear, so employ a combination of vacuum hold-down and air assist to keep the material cool and debris-free. Once the machining was complete, perform a manual inspection to check tolerances, edge smoothness, and dimensional accuracy.
After machining, the sign board undergoes sanding and edge finishing, followed by optional priming depending on the client’s intended paint or graphic application. These post-process steps are critical to ensuring the final product not only looks great but also performs in the field over time.
We are equipped to handle heavier, more complex signage jobs with the same precision we bring to every project, regardless of size. Whether you’re ordering a single custom board or planning a full signage rollout, our machining team ensures every piece meets exacting standards for quality, durability, and visual impact.
