    Manual machine to cnc handle feedback

    There are pulse generators which can give a torque resistance feedback by using a bldc motor. Multiple videos on YT how it works, quite cool!

    OT: Hydraulic position / stroke control / end of stroke valves

    Why not a regular electric valve and a switch?

    Belt Drive theory and basic knowledge ... for a practical example

    Perhaps a V twin might be a better option if you're out of space? 16HP twin could be found in lesser motorcycles or generators, and probably for cheaper, with better accessories and spares than a dedicated RC engine? Anyway, yes 80-90% is a good baseline for reduction efficiency in most cases...

    Belt Drive theory and basic knowledge ... for a practical example

    Would not be able to run a two stroke upside-down to get output shaft closer to the height of the prop-shaft and use a straight planetary gearbox instead?

    Ot...ship hits bridge

    Yes, there were rigorous training for all kinds of situations. I worked in the engine room and as such were part of the fire response team. We had sessions at least every other month. On top of that there were other training scenarios as well, can't really remember much of it as it became a "way...

    Ot...ship hits bridge

    I worked at sea when I was younger, only roro cargo ships and mostly spain-england-germany-sweden as destinations (car and paper freight). All ships I worked at had main engine generator, two aux. generators and an emergency generator located in a different location. Always when going in close...

    Grinder mode on 640MT

    Hi! Does anybody know how grinder mode works on an older integrex with 640MT control? The manual states M230 Grinder mode ON M231 Grinder mode speed setting When inputing M230 the mode is activated, and when running M3Sxxx the lathe spindle is rotating at set speed but the mill spindle is...

    O.T.- Can you help me with a hydraulic system mod?

    If you would go this way, make sure that you put a pressure relief valve after the flow divider. If it's a gear divider, it can also act as a pressure multiplier! Not applicable if it's a valve divider.

    O.T.- Can you help me with a hydraulic system mod?

    Flow priority valve is the way to go, they're made to solve exactly this problem.

    OT: Computer fan technology......the lost art. Plus workstation computers.

    I've been using Inventor and more or less daily open 2000-3000 part assemblys with textures since about 10 years back. I've had one desktop in the beginning of my career but laptops ever since. First laptop had an i7 Extreme 6 core desktop processor, 64 gig RAM and dual GTX 880M graphics...

    Metric button/round head socket cap screws with a deeper than normal head

    ISO 4762 is way more common here i EU than ISO 7380. 4762 heads are as tall as the metric screw size, ie. M6 have a head max 6 mm high. Though I've noticed often times they are a tad bit under.

    Best methods for many threaded holes

    Rivet nuts is a no-go? I have come to love them, bought a battery riveter for these nuts and oh boy is it fast, simple and looks proffessional! Usually stronger too.

    AutoCAD Inventor + CAM VS Solid Works + Mastercam

    Inventor CAM is dead, at most there are some bugfixes between later versions. It's easy to use though, especially coming from fusion. I've modified my posts to be able to drive my Integrex (4+1) and it works good but I would never even consider ICAM for 5 ax simultanious. To be honest I would...

    Tapping Acetal/Delrin

    If the thread is going to be repeatedly used I would recommend using an insert of some kind. One often forgets and pull the screw a little too tight which might be destructive in the long run. It's a cheap insurence. Other than that, acetal/POM is more like aluminium than most plastics in that...

    Cincinnati 500 arrow look ahead issue

    What control is on the machine? And what options? I run an Arrow 2000 with acramatic 2100 and have absolutely zero issues with high speed toolpaths from fusion/Inventor CAM. Regurlary running 1500-4500 mm/min feedrates and no jerks or stops without any smoothing. In fact I noticed it runs...

    Mazak Integrex 200SY mk 1 (Fusion 640MT) Cycle start without Y at home

    I always run with barriers off, to much high mix - short run parts for me to set them up every time. I've learnt to trust my post processor and a tape measure to stay clear of crashes so far.. :D

    Servo motor for 10 kN electric press

    Steppers should work, but I would calculate atleast 19-20 Nm.

    Servo motor for 10 kN electric press

    The answer is you need at least 19 Nm on the input shaft with 85% efficiency (std for ballscrew). If you want 50 mm/s you need 19 Nm @ 300 RPM = 0.6 kW If you want 25 mm/s you need 19 Nm @ 150 RPM = 0.3 kW The thing is, which ever you choose you will need reduction. A standard servo usually...
