Things to Consider when Buying Best CNC Router Spindles

Are you considering purchasing the best CNC router spindle?

Then evaluate the variables to think about while purchasing the best CNC router spindle.

Spindles for Routers

There are mainly two types of spindle power: water-cooling and air-cooling spindle.

The water-cooling spindle has a low power output, ranging from 1.5 KW to roughly 2.2 KW.

These spindles work well with a variety of materials, including MDF and PVC.

They’re best for projects that include soft materials.

Water cooling routing spindles are ideal for folks who have a lot of tasks on the go.

Spindles with air cooling, on the other hand, are ideal for large projects.

These spindles can be used to cut or engrave the units.

Spindle Speed

Choose a CNC router spindle that is faster, allowing you to work with greater precision, efficiency, and speed.

Furthermore, CNC router spindles on the market allow you to adjust the speed to meet your needs.

Spindle Voltage

Select the CNC spindle, which has a higher voltage input than the total current.

As a result, there is greater output, which leads to more voltage, which is proportionate to the current.

For example, an AC voltage of moreover 200 volts is sufficient to cut solid materials and wood.

Spindle Type

CNC Router Spindles are classified into three types based on their work mode.

Cartridge spindles are the most common type of spindle used in vertical machining centers.

The fact that they provide a high-quality product makes them the finest option.

Furthermore, they do not necessitate the use of an engine or transmission.

They also include a rotating assembly.

Finally, unlike constructed spindles, such spindles are simple to make.

Fabricated spindles are the next form of a spindle, and they are difficult to deal with.

CNC router spindles are difficult to change, which makes them difficult to use.

Power Rating of CNC Spindle

A high-power cutting spindle and a fine machining spindle are the two types of CNC router spindles.

Low noise, high precision, and fast speed are all features of fine machining spindles.

Such spindles have a modest power consumption of roughly 250W.

These CNC router spindles are designed to operate on delicate items such as nameplates, badges, seals, and gifts.

Because these spindles have low cutting effectiveness, you must exercise extra caution when utilizing them.

High-power cutting spindles, on the other hand, have excellent cutting capabilities as well as a large amount of power.

Spindle Rotational Speed

Before purchasing a CNC router, make sure to check the spindle speed.

The nominal value of spindle speed is inscribed on a plate with 12000, 15000, 18000, 24000, or 40000 rpm, which indicates the number of revolutions per minute.

The inverter regulates the revolutions, but the spindle’s power is calculated by multiplying the torque value by the rotational speed, which keeps the torque while reducing the revolutions.

However, high-speed spindles are not suitable for all materials and are only manufactured at low power levels.


Choosing a CNC router spindle that lasts a long time is critical.

Choose one that is made of a heavy material rather than one that is made of a less expensive one.

Aside from that, it’s critical to select a spindle with a rust-resistant texture.

Spindle Quality

Make sure the CNC router spindle comes with high-precision bearings when you buy it.

If your spindle lacks high-precision bearings, its performance will be poor, resulting in the machine overheating after long periods of rapid rotation.

Even if you experience harmonic revolutions with uniform speed, such spindle motor performance can have detrimental impacts on the spindle motor’s service life.

The only criterion for determining the spindle’s quality is that it should be able to cut hard materials at high speeds.


The budget is the most important factor to consider first.

It’s perfect for getting the best CNC router spindle, but you must take your budget into account.

Make a reasonable budget and decide how much money you want to put into it.

The industry has a wide spectrum of machines, including low-ranged, high-ranged, and mid-ranged equipment.

Choose the CNC router spindle intelligently among the many variations available on the market.

FAQs on CNC Router Spindles

How do I choose a CNC spindle?

You can choose a CNC spindle with the RPM, power, and cooling that your material requires.

A spindle with 24,000 RPM and 1kW power is suitable for wood and aluminum.

For steel, RPMs of 15,000-18000 and a power of 5.6 kW are sufficient for tools up to 12mm in diameter.

What is an ATC spindle?

Automatic equipment change spindle motor (CNC ATC spindle) is a short name for Automatic tools change spindle motor.

It was formed to fulfill the demands of high-speed, complicated machining.

When a CNC machine or router is equipped with an ATC spindle motor, the efficiency of the machine or router can be increased by 3-5 times.

How big a spindle do I need?

For steel, you should use a lower rpm spindle (15,000 to 18,000 rpm) with cutters up to 10mm 3.3kW spindle, cutters up to 12mm 5.6kW spindle, cutters up to 16mm 7kW spindle, and cutters up to 20mm 10kW spindle.

What is a good spindle speed?

Ideal speed for spindle depends on the task one is working on.
