- Using a handheld router may be time-consuming. Also, it may be intensive, requiring physical strength.
CNC Router
Like all CNC devices, a CNC router is a sophisticated computer-controlled device that uses a router to cut, shape, and machine various materials. Unlike the handheld device, the CNC router operates independently, using pre-programmed computer software, which directs the cutting bit along specific paths according to the design input. The designs are usually created with CAD (Computer-Aided Design) software before it is converted into machine instructions (G-code) that the CNC router executes.
Advantages of CNC Routers
The advantages of CNC routers are not far-fetched; they include the following.
- CNC routers offer unparalleled precision and accuracy. They can cut intricate designs to exact specifications with minimal margin of error.
- The device is automated, such that it can execute its operations independently after programming, requiring minimal human interference, even when machining complex structures.
- CNC routers can operate around the clock, making them efficient for bulk-volume projects. They deliver uniform results across multiple parts, which is essential for mass production or for creating identical components.
- CNC routers can handle complex designs that would be difficult or impossible to achieve with a handheld router.
Shortcomings of CNC Routers
- CNC routers are significantly more expensive than handheld routers, often requiring a substantial investment, especially for small businesses or hobbyists.
- CNC routers are large and typically require a dedicated workspace, which might be challenging in smaller shops or home workshops.
- Operating a CNC router requires knowledge of CAD software and programming, which can be less intuitive for users unfamiliar with digital tools.
Differences Comparison: Handheld Router vs CNC Router
Thus far, we have shown you that handheld routers and CNC routers have their benefits and shortcomings. The choice depends on your project, with various determining factors requiring consideration.
We have briefly discussed some of these factors. Below, we highlight them, providing more information to enhance your decision-making between a handheld and a CNC router.
Control and Operation
Handheld routers allow manual operation by the user, requiring hands-on control to guide the tool over the workpiece. In contrast, CNC routers are bulkier and more sophisticated, requiring computer codes and programs (G-code) to function. Therefore, handheld routers afford the machinist total control of the cutting operation. On the other hand, CNC routers operate with minimal human intervention after completing the machine set-up.
Cost
Handheld routers are more affordable, with lower upfront costs, making them more accessible for hobbyists and small-scale operations. However, CNC routers are expensive, requiring a significant upfront investment. Besides, this also includes excessive maintenance costs, software updating, and potentially additional training.
