Router vs Spindle for CNC Machine

Routers are consumer-grade equipment that is good for cutting materials for short periods of operation.

On the other hand, Spindles are constructed specifically for CNC machining applications and can run for long durations without losing precision.

If your project demands are low and do not require continuous operations, a router is an affordable alternative for spindles on a CNC machine.

Routers are easy to set up and do not require a complex drive mechanism to run them. You can plug in the router to any wall socket, and you can start cutting.

Whereas, most spindles will require you to have a separate controller or drive circuit to function optimally.

However, when you choose a router, you lose the precise speed and torque control levels that a spindle offers. 

Additionally, routers are noisier than spindles and do not have water cooling options.

The runout on routers is more than that on spindles which affect the accuracy of your CNC machine.

However, for beginners, routers are much easier for getting started with CNC.

On the other hand, choosing a CNC spindle is an exercise that requires a lot more research.

If you need high precision and long hours of operation you will need to use a spindle for your CNC machine.

In conclusion, if you are a hobbyist or maker who does occasional works on your hobby CNC machine, a router might be enough for your requirements.

Factors to consider while selecting a router for CNC

Speed

Speed is one of the major criteria to be considered while selecting a router.

Different applications require different speed ranges.

When using tools with large diameters it is advised to go at slow speeds.

Additionally, using small tools requires high speeds to keep the feed rate efficient.

Woodworking typically requires speeds that are over 16,000 RPM and machining metals like aluminum requires speeds lower than 20,000 RPM.

So, choose a router that has a speed range applicable to your requirements.

Hosepower

The horsepower determines the material removal rate and also the speed at which you can cut.

A high-powered router can cut faster than a low-powered router. If you need fast project completion time you should prefer a router with a higher horsepower.

It is always advisable to have a router with at least 1hp of power. Anything lower than 1hp will be too slow for CNC applications.

Collet size

The collet size determines the size of the tool you can use for cutting.

Select a router with a collet that can accommodate all the tools that you intend to use.

Warranty

Routers are devices that are in constant motion for long periods. Hence they are prone to damage, and having a good warranty period can be an advantage.

A warranty will save you from additional costs in repairing your router, and the warranty of a device is also a testament to its build quality.

Frequently Asked Questions (F.A.Q)

Can a router be controlled via G-code or software?

You can turn a router on and off via G-code or software. You will have to create a relay circuit in order to achieve that. The relay can be controlled via the controller of your CNC machine and it will turn the router on and off. You can also use controllers provided by many manufacturers to achieve the same. For example, Carbide 3D makes BitRunner, an accessory that can turn the spindle on and off via G-code.

However, the speed cannot be controlled as the speed control in most router is through manual adjustment of the dial on the router.
