What are Spindles and VFD’s?
Its a great starting point, or an excellent upgrade from traditional AC Routers like the Makita RT0700 or DEWALT 2600.

Variable Frequency Drives known as VFDs or VSD are technically speaking, Inverters which operate over a wide frequency range. An inverter can change DC current into AC, but for our purpose, we are taking a single phase in (your mains power), rectifying it to DC before inverting it back into AC split over 3 phases and from 0 to 400Hz. Most simply powering and managing the speed of a 3 phase spindle all from only a single-phase input. The VFD accepts a 0-10V signal from the CNC controller to manage the speed of the spindle.

Why is this important?
Automatic CNC of a spindle provides a smoother workflow.

Lower run out on the superior ER grade collets provides a better finish and longer tool life as well as offering a wider range of collets in metric and imperial sizes at up to 13mm (for ER20 series)

3 Phase spindles are designed for constant operation and so will run for many more hours in a day, over a trim router (Makite/DeWalt).

The comparably whisper quiet operation wil be appreciated by all.

Makita, dewalt and similar wood trimming routers are single phase brushed motors, which can produce a lot of both audible and electronic noise, require the brushes replacing at intervals and is actually only designed for short use. The spindle speed is so fast that cutting material like aluminium can become tricky. They do serve a purpose and are great to get cutting at a budget, but for longer, more precise jobs, a spindle and VFD are an excellent choice.

Make The Perfect Carve

To keep things simple, we have packaged together all you need to load your CNC machine with a Spindle set up. Included is Spindle, VFD, VFD cable and wiring diagrams, collet and locking nut. You just need to decide what size spindle your machine can take, by learning more below.

Get Great Detail

Our 3DTEK spec spindle solution is grounded, safe and highly reliable. Our VFDs are high quality European designed, produced, & approved for use worldwide. This ensures you have the best quality products to produce the highest of quality projects.

Take a step towards a professional set up. By selecting one of our Spindles and VFD’s, it ensures just that.

High Quality, High Reliability

There are many inverters options on the market. We have tried them all from the ‘Cheap Chinese’ to the super expensive versions. The best we find for value and performance is the Invertek series. Crucial to its performance is the onboard EMC filtering. VFDs and Spindles are inherently electronically noisy. with this in mind, quality components, good PCB layout and stable firmware result in a quality output meaning a quality finish in your work. These purple coloured drives have it all.

Finally, pairing with a heavily shielded specialist VFD cable ensures your jobs run uninterrupted and finishes how’d you expect.

1.5 kW Ø65mm ER11 Spindle & VFD

Nimble, 65mm diameter 3kg spindle. Perfect for lightweight, ‘DIY’ and any machines susceptible to flex under load, or with Z axis steppers unable to lift heavier spindles. Move away and upgrade from a wood router for precision finish, great control and reduced noise.

The 65mm spindle body allows this spindle to fit into all 3DTEK XYZ-Carve Machines and any other machine using a 65mm clamp or bracket. This 65mm Spindle shares exactly the same diameter body as the Makita RT0700 router. The ER11 collet system utilised by this spindle accepts endmills to Ø7mm
