80mm spindle and VFD choices

Well I pulled the trigger on a 65mm 1,500 watt 110v water cooled … now I have 2 months to study and learn. The motor feels beefy, I’m not sure I want an 80mm. I think I made the right choice for me.

Rhoffart,

Where did you get your vfd and spindle do you have link?

I have the same unit but can’t find the settings for the vfd 220volt? Could you please share the settings you used? I hoping to have my 1F by mid June . It is in the week of May 16. I’m pumped.
Thank you so much

If quality is what you are seeking this is hands down the best option for you, if you don’t want to jump up to 80mm. Mechatron GmbH
They make a properly fan cooled air-cooled and water cooled spindles in 65mm and if you want to add the additional weight, they sell 80mm and 100mm as well.
Considering the quality, plug and play options they have available for VFD prewired in a cabinet.

I just ordered a complete cabinet package, and look forward to installing it once my “Woodworker” arrives in a few weeks.

I have many years experience using these spindles in a professional environment, they are designed to run in industrial manufacturing settings and keep tight tolerances.
I had terrible luck with the "no name spindles and VFDs " that plague all the inexpensive places we buy from, but rather than call them inexpensive deals , they are “cheap and dangerous”, paying a little more for something precise, and well built and safe from the start, is a good start.
My current Mechatron 100mm spindle has been perfect for nearly 5 years and ran nearly 24 hours a day for a year.

Don’t risk burning down your shop, or home, and investments on products that need to be modified highly to work safely and effectively, if the spindle and VFD have no “real UL or CE listing” and no real tech support, I would advise to just use the Makita option, make some money with it and invest, or save a bit longer and buy quality products.
As far as VFDs, I would look at Fuji, or Omron, few bucks more and huge difference in quality safety and support. These things are dealing with amperage that can kill, if they have no technical support, I’d stay clear unless you are proficient with electrical work.

If you interested, Rainer Wohlmann is very helpful and great communication with us English speakers.

Hope this information helps others, and I’ll keep you posted with the install when my Onefinity finally arrives.
Be well Everyone, and I’d be happy to share what has worked with me in the past on other machines, and what I use in a professional environment.

Would you mind describing the equipment (model #s, pricing, specs, etc) of the components in the cabinet configuration you purchased? I am curious how it compares to some other equipment I have been researching. Thank you, Tom

@Grunmaschine , I too would be interested in some more details about what you purchased. I understand they deal with direct quotes so I don’t expect you to be exact but I’d appreciate some ballpark numbers.

I got a price of about $1000 for a 2.2kw water cooled German made spindle and about $300 for a good quality (I think Hitachi) VFD. For me I would need to be using my 1F to make money to justify the cost.

Are there any 80mm routers?
.

We will not sell OR provide technical support spindles or vfds.

We will provide support for the 80mm mount HARDWARE only. If you go the spindle router and have issues with the spindle/vfd, you’ll need to rely on the community for support.

Makes total sense. You are a small and growing company. You need to manage where you allocate your resources. Much better to have them working on something a high percentage of your users will gain benefit. Most interested in an 80mm spindle have the know-how to run it themselves. For those that don’t, there are plenty of other resources available.

Liquid vs Air cooled spindle?

Many of the industrial machines use air cooled spindles, very few that I have researched use liquid cooling. This applies to large Milling machining centers as well gantry style routers.

My logic is as follows, if you are cutting mainly wood, and seldom use anything larger than a 1/4”/6mm end mill, then air cooling should be more than adequate. Even when using the larger cutters, generally the time is relatively short because those tool paths are for roughing /clearing or profiling. The tool paths that are hours long for 3D finishing cuts typically use much smaller ball end mills with very low spindle load.

There are surely some exceptions, like using 1/2” raised panel bits, but I still think air cooled would be fine. Every hand router and stationary shaper do just fine being air cooled. Maybe adding a heat sink for those corner case heavy cutting jobs.

My feeling is that water cooling just adds a lot of extra stuff that “could” go wrong…more tubes to the spindle , water reservoir or chiller etc…and always the possibility of a line breaking ruining your work piece, spoil board etc.

Anyway, would love to get other folks opinions.

Cheers

Tome the difference between air cooled and liquid is dust. A fan will suck it into the motor. A liquid cooled spindle has no limit to how slow it can turn (as far as cooling goes) where as a fan cooled spindle is limited to about 7000 rpm. Shouldn’t be too much of an issue for woodworking. A pump should also be quieter than a fan. Also shouldn’t be too much of an issue since the bit is going to make plenty of noise. Air cooled is easier to install since you don’t have to deal with the cooling lines.

Good point, the fan blows down, but will still suck in some dust and eventually require some cleaning. I noticed most of the import spindles state a minimum speed of 9k rpm, independent of air or water cooling . Agree with the noise, I must admit, I thought the cutting would be loud, but after I do a roughing pass, the small ball nose cutters are taking such small cuts that the majority of the noise is just the motor…for quiet operation, liquid cooling would be a thumbs up

Good Evening TMToronto,

Sorry for the delay, I’ve been working around the clock, and traveling for work, and just able to decompress and reply.
So I ordered the HFS-6515-24-ER11 spindle, a plug and play cabinet, with comes wired and programmed VFD, input filter, braking resistor, main power switch, circuit logic for emergency-stop and reset button, and wired so meticulously, I ordered the Pro Series spindle which is overkill, but I plan on working in aluminum and thinking of a tool changer down the road.
I opted to use an old TIG cooler rather than the unit they quoted me.
The price was about $1300, you could save some money and source the VFD , and build your own box and source your own components, but the build quality, and time saved with plug and play, is worth it for myself with my schedule and needs.
Some saving could be had with the standard series spindle, they do also make a 80mm spindle in air and liquid cooled, just like the 65mm. The quote will vary by exchange rates and what country shipped to.

Hi all
I will be purchasing a spindle/VFD when my 1F arrives, however since I’m not yet able to go down the Mechatron route has anybody got any feedback for the Huanyang brand spindle/VFD’s.
I was all set to buy before I read the safety comments regarding ‘no name’ parts in the thread. If anyone has had fires or malfunctions due to the build quality of Huanyang spindle/VFD’s I would really like to know.
Feedback appreciated.
Thanks
Lee

Thank you for taking the time to reply and provide this information. I have been in contact with a Mechatron representative, and have received a quote. I asked them for details about the manufacture location and bearings - German design/manufacture, and the ball bearings used were metal. Do you know if the Pro Series spindle you bought also uses metal ball bearings, or do they upgrade to hybrid or full ceramic? I am curious as one of the better Asian spindles I got a quote for (Jianken) use ceramic bearings. It may be a mute point given the practical uses for the 1F, as well as the quality variations/precision grade ranges found within different bearing categories.

I have been using that setup for the last few months. Works very well. Biggest hassle was wiring the VFD to the spindle

I did a lot of research before I bought the spindle and the huanyang VFD and spindle is the recommended brand, unless you want to go big bucks and get one of the German spindles. Have used it alot over the last few months and it had worked flawlessly. You will need to source the VFD to spindle wiring yourself s or does not come with it. You will need 16 or 18 Guage 4 wire shielded cable. Make sure you ground the spindle itself.
