As powerful and customizable as CNC machining is, it is also a relatively simple process. Once the computer loads a CNC program, written in G-code or M-code, the manufacturing process can be fully automated.

To get to this point, the component’s designer first develops a CAD model of the desired component. CAM software reads this CAD file, checking it for errors before generating a CNC program. This program dictates the coordinates that the cutting head will traverse in crafting the physical component, as well as parameters like speed and RPM’s. CAM software also determines the most efficient orientation of the CAD design on the material block to minimize waste. The final CNC program conveys all of this information to the computer, which then controls the cutting head’s movements, so they align with the instructions.

CNC machining has many benefits over traditional manual manufacturing techniques. From a single program file, a CNC mill can produce anywhere from one component to several thousand, all of which conform to the exact specifications from the original 3D model. Additional advantages include:

• Efficiency: CNC machines can run continuously with little to no intervention from human operators. This automation drastically increases productivity compared to manual methods, decreasing labor costs and freeing employees to focus on their areas of expertise.
• Consistent Results: CNC machines can replicate their programmed design in any volume, with each iteration adhering to the same dimensions and precise tolerances. With no possibility for human error, CNC machining nearly eliminates variation between components, so it is an ideal choice for high-precision applications.
• Reduced Costs: CNC machining is often the most economical choice for higher volume production runs. The machines can run with less personnel and produce less waste, reducing expenses on multiple levels.
• Flexibility: CNC machines have flexible capabilities in that they can accommodate almost any material and geometry, but they also enable flexible production processes since they can be reprogrammed quickly and with minimal effort.
• Advanced Capabilities: CNC machining enables more intricate designs than could easily be achieved manually. Automated processes like CNC are the best choice for highly complex components, especially those with fine details.

We have experience machining an array of metals and non-metals. Popular options include the following.

HARBEC has a long history of building and maintaining high precision production tooling, and lower volume prototype tooling, to meet our customer’s needs.  Our fully equipped mold shop partnered with our engineering team can take your project from design to production, and our skilled maintenance team will keep your tools running in top condition for many years. 

Our mold making team utilizes many of the machines listed in our capabilities list to produce tooling components whether it be through CNC machining, wire EDM, sinker EDM, grinding, and polishing.  Our mold maintenance team is fully outfitted with its own CNC machine, Bridgeport, and manual lathe to perform tool repairs when needed, as well as ultrasonic cleaning and polishing equipment to keep our tools running like new.  Our in house micro laser welder also helps reduce down time on tool repairs since we can keep the work in house and turn around repairs in hours instead of days.    

HARBEC strives to be a full-service partner for our clients, so we offer a full suite of secondary services to ensure the product we ship meets all production requirements. Our secondary service offerings include:

• Assembly
• Form-in-Place gasketing (FIP)
• Gun drilling
• Broaching
• Pressing
• Plating (including nickel plating magnesium)
