Nozzle Adapter Samsung CP40

[Frank Herrmann]

Hello Friends, 

yesterday i got this nice nozzle adapter in my hands. It's an Samsung CP40 and i have to say, an amazing piece of work. The nozzle N045 (0.45mm) is made in plastic and the adapter in brass. 

You put the noozzle only on the left side with the rubber rings, thats all and this system are airtight. The spring is in the adapater and this make the noozles very cheap ($5).

To make a automatic change with this adapter it's very easy: https://www.youtube.com/watch?v=tfw4NG-tlaw

I guess my runout Problems with the JUKI Adapater are gone, cuz i'll use Samsung CP40 in future. I need only a delron(POM) adapter to install this on a 5mm hollow shaft.

More news coming soon, but first here the photos: https://goo.gl/photos/wbdiFHWiHwD1XmVd6

Hi Frank,

Thanks for posting this. I was just looking at these nozzles earlier today. I'm very interested in them, and in the CP45 nozzles. The ones shown in the video you linked are the CP45 Neo nozzles, I believe. Difference being that in the CP40 the spring is in the holder and on the CP45 the spring is in the nozzle.

A few questions:

1. Did you consider the CP45 nozzles? If so, why did you decide to go with the CP40 over the Cp45?

2. Have you tested the runout on these?

Jason

Jason , yes that is CP45 Neo nozzle , that is my video , but I m not so happy with that nozzle  , this CP40 look me like better solution .

[mojalovaa1]

Frank , have you some link for see price and other model of the nozzle ?

It was a price decision, cuz the nozzles are more cheaper w/o a spring load.

Not now, i dont know how can i do this without a shaft. I'll mill a adapther for a 5mm hollow shaft, 

• but first i don't have so much time now, 
• how can i remove the old JUKI robodigg adapter from my nema 8 stepper? 
  

But IMHO, that's a professionell adpater. I don't think that we run in a big runout with these guy :) 

To prepare an Adapater for a nema8 are easy, i ordered a delrin (POM) round bar and will mill a hole 4.9mm for hollow shaft and a 4.5mm for the threaded rod (i guess it's M5), the rod will cut his way in this hole and it's airtight and centered ... hopefully :)

This guy are very nice, he try to call/smd me cuz i dont wrote him which nozzle i want, i thought it's the price for 6 nozzles :) Very nice contact and after 3 weeks delivered.

Mine required quite a bit of pressure on a bench vice to install. I think that it will be very hard to remove without destroying the motor. 

But IMHO, that's a professionell adpater. I don't think that we run in a big runout with these guy :) 

Could be. I thought the same for the Juki and still get quite a bit of runout. Although with this one there are less areas for error to creep in, I think.

I'll be interested to see how it turns out. I have some concerns about using threads to center things. Very curious to hear your results.

[Michael Anton]

You are right, threads don't really center things very well.  Perhaps the intent was to center on the top of the shaft, with a tight fit bore, and then the threads are deeper into the part.

[Oz-Ron]

The second photo shows the thread leads to tapered shoulders on the adapter.  These would mate with a tapered seat giving a reasonably accurate center I should expect.  Just wonder how much play there is in the CP40 adapter due to the spring arrangement?

 

For info, I have found the RobotDigg adapters can center the nozzles OK if the screws are adjusted to achieve it.  However, the time it takes to do it is a pain.  

Ron

[Frank Herrmann]

Correct, the hole for thread are deeper and i'll use the small cylinder to center this thing in the adapter. But Ray found a stepper with a inner M5 thread, but sadly on the rear side of this stepper:

Frank I have that motor to my new machine , screw is M5 but nozzle holder for CP45Neo is M3 with fine thread .
What is dimension screw  on the CP40  nozzle holder ?

Second problem is  that hole is not on center and difference is  more then 0.1 mm  , I m make new shaft  for that .

I don't know, i'll measure this today after work. Maybe M5 but never M3 :)

I use this one on my PNP machine:

[mojalovaa1]

Have you maybe some information , how much is cost yours machine ?
Can you say me it is hard change nozzle on that  nozzle holder ?

[Михаил Юров]

I bought parts directly in China.

All components have cost me about $ 700 - 800.

The force required to remove the nozzle about 10 Newtons (1 kg)

If the lubricate sealing rings with silicone grease - the nozzle is removed much more easily.

Ok, i measured now, here the result: M5 :) 

[Anthony Webb]

Thought I would point out that the adapter can screw into the hollow shaft steppers from robotdigg:

hey Anthony, a very good Catch ... many thanks for this link!

[Juha Kuusama]

Here is a design for an holder for these: http://liteplacer.com/phpBB/viewtopic.php?f=11&t=192&start=40#p2023. CAD files and a link to a video is a few post down on that thread. A potential problem I see is that vibrations might cause the nozzles to move in the holder. And if the nozzle is not directly under the shaft when it goes down to install a nozzle, bad thing happen. this is easy to fix; place a hole and a bolt behind each slot and install a spring to hold the nozzles in place when they are not used. Here are my experiments with such a spring:

[A commercial pitch: If this is against the rules here, I'm sorry, I'm new here. Anyway, more than likely, I will be offering the holder, a set of nozzles and the head on my shop in a few months, once I get it designed and debugged, as well as an upgrade kit to my machine.]

Hello Juha,

just in time :) At the weekend i found this article and get the DXF Files, thanks god not so much work for me. The spring loads are nice but please, can u make a photo of this sprong load but installed on the holder. I can't realize, how will works this on the holder?

I don'thave a photo yet, as I don't have parts for a redesigned holder. Referring to the photo in the link, the idea is to place bolts directly behind the holder slots. The bolt keeps the spring down, and the two U shaped ends of the spring go in to the slot. The nozzle goes between the ends and when released, the spring pushes the nozzle down and back, so it aligns at the end of the slot.
