Re: ATC leaking air help

I had to replace both on my Triac when I bought it. I bought them from https://www.airlines-pneumatics.co.uk/pneumatics/cylinders/mini-iso-cylinders/cylinders-mini-iso-parker-p1a/s030100/ although I see prices have gone up quite a bit since I bought them. I think the up/down ram is part number 10560...

Re: Hot Spindle Bearings

Too much grease can be worse than too little grease, but excess grease should work it's way out.

It sounds like you've possibly ran the spindle up too fast. I'd normally increase spindle speed in 500rpm increments every 15minutes, ensuring there's no significant heat generated before each increment.

Re: Hot Spindle Bearings

Sounds like you've overtightened the bearings. How long did you run the spindle for between speed increments? Try slackening the retaining nut slightly (probably 1/8th turn would do to start with), and running again. If the spindle is warming up after 30 minutes of running, you'll have it about righ...

Re: Phase converter

At the minimum you'll need a rotary converter, as a static converter relies on having a motor attached to generate the false phase. Off course, you can just attach a big motor to a static converter to create a rotary converter. I have been experimenting with using a 4KW boost VFD (VFD with built in ...

What is wrong with your turret?
I had a slight mishap setting up a new tool, so one off the internal planet gears is now a rather expensive jigsaw.
I'm just waiting to hear if the parts are still available, and if they are, how many limbs/organs they're going to cost :?

Re: Leader pneumatic air chuck replacement with manual chuck

What is the largest manual chuck anyone has put on the Cyclone? The spec plate says 150mm max but that seems to be a non-standard size. So I've got the choice of either 125mm or 160mm. I would prefer the 160mm but would that cause a problem? I found out that the 200mm (~8") backplate is actually an...

Re: TU150U in need of TLC

Looking good. One question, see the plate that is sandwiched between the cross-slide and turret (the one with the two grubscrews to secure the cover that moves with the X-axis), did you happen to have it off? If I can't get the bits to fix my TOE80, the smallest turret I've found is 50mm centre heig...

Re: 4th axis for mill

My advice for FWIW is to buy a reasonablby priced 4th axis direct drive or belt drive type, the worm and wheel type wear very quickly unless you pay big money for a high quality one. I have a Sherline one on a Triac and it really isn`t very good, when I get the chance/time to get back into my works...

If you want to get a rough idea how much torque will change, just run some numbers through a HP/Torque/Speed calc such as - https://ncalculators.com/electrical/horsepower-to-torque-calculator.htm Or if you want to get a bit more geeky, you could create a spreadsheet with a chart :lol: (hint - if you...

Re: Cyclone TU150U spindle power clarification

You mention that they maintain constant torque to 3kW although on my machine plate it says 2.2kW. Does your machine have a higher rating? I wonder if I would lose anything with 230V Delta as that has constant torque up to 2.2kW, the same as the rating plate on the machine? Sorry, should have said 2...

Re: Cyclone TU150U spindle power clarification

I think my Cyclone is a similar age. The motor is inverter rated, so the plate can be a bit misleading if you don't quite understand what the numbers mean. A key principle to understand, is torque is proportional to current. As motor speed increases, the voltage required to drive the current through...

From my notes, the parker SD drives were set at 2A for X and Y, with Z running at 3A. I thought I had the motor part numbers somewhere, along with the datasheets, but I can't find them.

Re: Triac Spindle stopped working

What fuse have you checked?

Depending on the exact setup, there is likely to a main power supply fuse (which should be OK as the control rack is powered), then another DIN rail mounted fuse just for the spindle, then there could be another fuse on the actual speed controller itself.

Re: Sprint 400 10v input & grounding

It depends on your BOB.

Better ones will have the 0-10V circuitry isolated, provided you use an isolated supply (usually requires 12V), which is easily done with a DC to DC isolating supply.
And some will have an isolating supply on board.

Have you got a link to the BOB you're using?

Re: Wanted - Computer/Control mounting arm for Triac/Cyclone

My Cyclone never came with one, and now that I've nearly got a new control panel made for the Triac, I'd quite like to make one for the Cyclone, rather than just have a computer sat on top.

I can make one, but I was hoping somebody would have one lying around to save me the hassle.
