Computer numerical control, or CNC metal routers carve metal blanks into parts and products automatically and repeatedly once programmed, saving you labor time and providing a higher degree of accuracy and consistency. More than just cutting, metal routers can drill, mill, turn, etch, hone, bore and even weld, using bits, water-based abrasives, even lasers.

In order to repeat their automatic functions, CNC routers for metal link up with CA computer-aided design (CAD) and computer-aided manufacturing (CAM) systems. Coupled with 3-axis to 5-axis machining capabilities, you can set up this equipment to handle any assignment from the most basic carving to complex projects for the automotive and aerospace industries When considering your own CNC router, think through three aspects of the system:

1. The heart of the system, the machine routers themselves;

2. Repair and replacement parts for industrial routers;

3. Options and accessories to expand the capabilities of your machine router.

Action Steps
The best contacts and resources to help you get it done

Contact metal router suppliers with comprehensive systems

As no two businesses are identical, your shop's customer base dictates the type of machining you do. Get in touch with a manufacturer that offers a comprehensive line with an adequate option list to choose from, or the capability to produce a made to order router.

I recommend: Warthog CNC produces a full line of routers from very basic build-your-own tables to laser cutters. Precix Advanced Cutting Technologies claims to design and manufacture the fastest 3D routing tables.

Use metal router distributors to stock the right replacement parts

Once the router is set up, keep it running consistently with top quality replacement parts, from motors to spindles and bits.

I recommend: MultiCam supplies a full line of tools for CNC routers. ez-Router offers a comprehensive list of parts and supplies, from bits and motors to controllers and probes, even the ability to add an axis.

Accessorize your industrial router to expand its capabilities

Grow your business by investing in accessories beyond cutting bits such as rivet guns, high-speed spindles, drill and tapping heads, ink marking systems, vacuum hold-downs or custom programming software.

I recommend: FlexiCAM offers seven standard router systems plus the option to configure a custom system for your workload. They offer dozens of options from adjustable and multi-angle heads to drills, bellows and welders. Techno CNC Router Systems offers a full range of accessories, from additional axes and coolant systems to laser scanners and an integrated camera.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Do you operate your CNC metal router occasionally or for lighter projects like small pieces or prototyping, or do you run a full day or even multiple shifts? Determine how hard you run your equipment before placing an order. This helps you decide whether you need a phase converter or even a separate power supply to adequately feed the router, special auto spindles to swap out router bits for you or more expensive servo motors rather than stepper electric motors to move the cutting tools over the blanks with greater precision.
