Then maybe water cooling is a slightly more complicated but superior solution.
I'm now thinking about selling the HSD and it's VFD to get a water cooled Chinese ATC like this one. it's about the...
So, I made one and tested it.
Results are a mixed bag. I printed it (PETG, first try with ABS warped badly) It works, the shape increases the pressure, but the air flow is much lower than with the...
as you say, it's moving a lot of air. I'm going to try using an electric fan. From what I've seen, a 3A 12V 120mm server fan should do the trick.
I've designed a shroud that convert from the...
Yes, it's the cooling fan. I also have a smaller, 2.2Kw Chinese shaft driven fan spindle GDZ80-2.2, and the noise is much lower.
I expected a real HSD spindle to be a nice upgrade, quite...
Hi,
I just bought a recent second hand CNC that came with a MT1090-100-ER32 HSD spindle.
It really makes a very loud noise and I wonder if someone uses a similar spindle
and if that noise...
H1rg0n:
I now see that my title was misleading, as I imported the whole CNC milling machine and not just the (in my case small Bosch Colt) router. Here it is :...
Come back next week (or next year), and they'll have a prototype that works ...
Here is an "infinitely over unity" device based on exactly the same principle that produces torque without any...
dertsap: My post was mainly a reply to handlewanker's caricatural post.
It was just funny to see you reply as the fact that another guy was making fun of "old school" machine shop guys did not...
Hi,
As mentioned by "rowbare", 1mm precision is awful. If you invest in a CNC machine, it's to get quality results, not an automated way to make low quality stuff. On a faceplate, you will...
Keep crawling and trying :rolleyes: ... first time I used "they", it clearly referred to older close minded guys, but either you know that or you need to learn grammar, unless you believe we all...
Now it's getting funny ...
I'm a woman ? :rolleyes:
Looks like the "Older guy who like peeing in all four corners of his territory" hit close to home with you. To paraphrase your tagline, it...
I guess it's also a generation thing ... older guys consider womens venturing in "their" field as abnormal and strongly react to it. They like peeing in all four corners of their territory, they like...
Hi,
I'm from Montreal, Qc and I ordered a CNC router frame (from K2CNC) in the US. Shipping method was UPS, and the cost, as quoted by the vendor seemed reasonable. After digging a bit, I...
Is your parallel port a 3.3V model ?
if so, it can create problems with interfaces using 74HCxxx buffers or direct optocoupler interface with anodes to +5V. The reason for the problem is that 3.3V...
Thanks a lot for this information. I had seen SW4, but assumed "half current" meant 1A to 3A scale for smaller motors. I tried it today, and it works perfectly. Same torque while moving, and reduced...
I bought 3x KL23H2100-50-4B + 1x Kl23H256-21-8B, 1xKL17H247-168-4B, 4x KL8060 controller, 6 limit switches, an EStop and 2x KL350-48V power supply.
Fast service, good price, careful packaging,...
I bought 6 of them for my machine limit switches, but got straight lever types instead of the "simulated roller". It was easy to bend them into the appropriate shape, but I still wonder why they were...
Hi,
You will find it in the following file:
BoschColt3.zip
You will probably need to modify the attachment screws location as it's specific to the K2CNC Colt holder.
Please note this was a...
Thanks for your answers, from what I've seen, it seems like most formats are proprietary, and that makes it harder to exchange designs.

STEP could have been a good format,...
Hi, I'm new both in here and to CNC machining, just finished to setup a brand new KT-2514 with Keling steppers/controllers and a Bosh Colt router, then started cutting MDF for practice.
