Gravograph Pantograph IM3: Part 1 Refurbishing
Вставка
- Опубліковано 1 жов 2024
- I have coveted one of these machines for a few years. Why? Because I am shocking artist yet I would love to engrave some of the things I make. These were primarily designed for sign writers and commercial engravers going back, I believe to the middle of the last century. However the mechanical principle of the pantograph means that hopefully it can be used for more creative purposes.
The manual models have been superseded by CNC and laser engraving machines however these are still available. The modern ones cost well over £1,000.
One of the only differences I can see is that mine has a max motor speed of 3600rpm and the new ones seem to go to 18,000 which quite a big jump. I got this one for £130 at auction. As you can tell it needs some love and attention so I decided to make this video in 2 parts.
Part one: The refurb of the machine
Part two: Learning to use it.

Nick, just got one of these and did the deep cleaning also - a problem is that the clamp/vise rotates on its axis without a lock - I see zero on the right at 3 o'clock but there is no way for me to tighten a screw or clamp to keep it there - what is missing ? - help . . . .
Glad I found your video, I just got one 2 days ago and have been trying to work it out. Great info and visuals thanks for posting. Now to watch part two
I had one of these in my lab in Edmonton, at AGT. I thought I had died and gone to heaven.
That's great. Thanks so much.
Great video.. Here in Netherlands are a lot of second hand machines for sale...just bought one and getting back in the hobby..😀
So glad it inspired you. Good luck and thanks so much for the comment.
What you've done it's more than refurbishing. Well done my friend!! I'm very happy for you and I'm sure that we will see very nice things coming out from this beauty. Thanks for sharing this with us!

Thank you my friend 👍👍
The Gravograph IM3 is a current model.
Although I have CNC the manual pantograph can be used for a lot of things which CNC cannot do or which are complex to achieve.
may i ask where i can buy IM3 gravograph belt
Hi, where are you located? they are available on Ebay usually but there are still official spare parts stockists.
@@Ukenick i'm from pili camarines sur Philippines , bicol province sir.
i owned one unit of IM3 gravograph machine but the belt is totally cut off.
Hello Nick, very nice video. Looking forward to the second one. Do you know if a pantograph of this size could be used to make inlays in metal? I am talking about 2 mm depth. I am looking for a way to achieve that but I don't know if something like that one will suffice or if I need a big machine
Hello Panos, I will be trying this when I film Part 2. Brass, Aluminium and Steel. The manual implies it can only etch on steel not engrave so I am guessing it will depend on what you achieve.
Amigo onde posso comprar uma dessa?
Eu acho de vez em quando sobre Ebay. O uma nova aqui www.gravotech.co.uk/products/engraving-stations-cnc-stations/im3
What is the right Diamond cutter for the im3 gravograph?
I am so sorry, but I have not used it on glass. Your best bet would be to email the manufacturers. Sorry I can't be of more help
hi i am a gravotech engineer and the cutter you need for glass on the im3 is a 90 degree diamond cutter part number 20149
just email sales and gravotech and they will send you one
