@@MrPtrvazq I really don't know what to tell you about this. If your grinder has coolant, I guess it will be fine ..

@@machinistnick I think I'm going to do it a wee bit different.As knife maker I use heat to separate epoxied parts if I have to so that kind of answers my question. Thanks for the response

Those attachments (like drill stand, circular saw adapter, etc) you have, are for this type of Iskra drills with 2 bolt heads near the chuck? I have 2 drills exactly like the one in the video and I've been looking for manuals, catalogs or photos of those accessories to try recreating them with wood or 3D printers, but couldn't find any information about this on internet

@@fededemarcos1172 Hi ...how can I send u the photos of mine ?

The software is Open Source. You can use the JRE of the computer to run the app. The code is available on GitHub. Feel free to fork github.com/nsiatras/pdf-compressor

Thank you. The main "electronic" parts are 2 door electromagnets, with 280kg force and a 12V 2Amps power supply.

Hello, the red button is a gear selection switch. This drill has a high and low speed/gears. If you chuck turns freely then it must be on the higher speed. Try to change the gear to the lower speed and try the way I used to remove it. Otherwise you need to open the gearbox and find a way to "stall" the spindle shaft in order to unscrew the chuck

@@machinistnick Hi Nick, thanks for the swift reply. I tried the change of gear and it didn't help, but now I at least know what is the issue. I will sort it out. Again, thanks for the help :) Cheers mate

@@firstweekofwinter You are most welcome!

The power supply capacitors will maintain the magnetic field for 1 to 1.5 seconds. The drill will stop instantly

You get a spark and the circuit breaker goes off.

@paulsawczyc5019 i just meant wonder i you could have left a lil filler out for drill space

@@ahill7099 Oh - well you could just put a flat piece of steel on top of the magnet - maybe like 1/4 inch thick as a protector - it would still be magnetic.

Great idea )

It is an electromagnetic chuck

its a magnetic vise

@@ahill7099 No. It is a chuck. vise. noun. ˈvīs. : any of various tools with two jaws for holding work that close usually by a screw or lever

Nice build but confusing grammar. Drill chucks are devices used to hold a drill or other cutting tools on a spindle. You have made a nice clamp.

@@machinistnick that is definitely not a chuck of any kind

I already made a 20mm hole in the middle in order to avoid injuries.

It is a 2-component, clear solvent-free epoxy resin.

The collet is ER32.

The belt will hold. The problem you are going to face is that the bearings of the Milling Machine's spindle will be overheated.

Hello, I used a 12Nm Nema34 Closed Loop stepper and I also added 2 air pistons to support the head.

​@@machinistnick Ok I was planning on converting a BF 30, but had an opportunity to buy a cheaper zx7045... Unfortunately all my electronic is dimensioned for a bf30 (closed loop 8NM for x and y , and 10NM for the Z

@@machinistnick thanks

I do not own this machine anymore but I had changed the gibs with brassed gibs I built myself. The brassed gibs had much smoother motion and better surface contact.

Thanks @@machinistnick

It works for both direction changes, up-to-down and down-to-up and it also work for all axes (X,Y,Z,A etc.). All you need is to measure the backlash distance for each axis of your machine and add it to the $180 (X Axis) , $181(Y Axis), $182 (Z Axis) and $183 (A Axis) parameters of the SourceRabbit 4-Axis CNC Motherboard.

@@ifvmes6788 Are you on 64bit windows ? Did you download the Installation wizard from github.com/nsiatras/pdf-compressor/releases/tag/v1.0 ?

5000rpm is low for high speed machining. Ι mostly mill aluminum with 10mm 3flute endmills using 2650RPM at 1200mm/min. It is more torquey than speedy...

It is the Z Axis of a CNC router

The belt driven spindle has also a much smoother rotation and the finishing is a million times better than the geared one :)

@@machinistnick any link to the belt driven spindle ? did you make it yourself or was it an offshelf product

@@nullkuhlI built it myself

@@machinistnick pretty cool, could you post more details about it, i understand the gears part you built yourself, but what about the cylinder for the geared one and so

@@nullkuhl The main pulley is attached to the spindle's shaft. Take a look how I built it facebook.com/reel/586630006912055/

I use to align the tailstock to the headstock spindle bore. That way is always better.

It is not the sturdiest machine out there but... it worked... If you are asking me if I am going to do it again the answer is No. I wouldn't convert an other column mill/drill to CNC. There are better manual machines that can be converted to CNC. Check my other videos. I am currently working with a ZX7045 mill that I converted to CNC.

@@machinistnick OK that's interesting to know. I was just wondering whether without the Cnc adaption it was a good drill/Miller, I suppose at that price it will not be top notch.

@@patricksmith4424 It is actually a very good Drill. As for milling I can say it is bellow average, it is for very light use.

@@machinistnickyeh by the look of it, it seems more of a drill, good info thanks.

Yes, I actually did. 2 mounting points, one on the wall and one on the floor, always improves the performance of drill presses.

@@machinistnick thank you vor quick Response, was the reason the swinging of the Drillpress ? i have the same Problem, you can See in my Videos. best regards Thomas

@@thomasmuller6838 Exactly. The base of the drill press is a bit thin. The thin metal causes swinging. Adding a second mounting point to the wall eliminates the swinging.

@@machinistnick yes i will do ist Like you, 👍

I use a C7 DFU2505 Ballscrew

@@machinistnick do you remember how long?

@@jameslee522 About 700mm

i have the same inverter, it is fool proof. You take the 2 cables phase one, zero plug them into the inv. Earth must been plugin to. then you take the 3 cables from the 3 phase motor and plug them into the inv. the motor can be a 220V then it should be (should... check the motor wiring from the producer) in triangle wiring not STAR. It would get warm mine did, but it dint blow up. Lucky me. He did take the 2 powercables from the mainswitch. Very easy to do.
