Quite an Unusual one

[Boyan Silyavski]

Hi Silyavaski

You have been busy with CAD, nice drawings, what cad package are you using?.
And great to see you have assembled the parts and drives....
How do you intend to join all the steel sections and the vertical bracing? By welding?

From memory you are going to use this machine with an impact hammer to make musical instruments.
-
Will it be an air operated hammer similar to one of these? https://www.google.com.au/search?q=a...w=1215&bih=817

I was using a small one hand one last week to break up some concrete. they cam deliver quite a blow, You can turn them down by using both a pressure and flow regulator. the settings will depend on what sort of material you are acting upon. even at a low setting the energy released is significant.

Tubular steel is very strong no doubt, however it can vibrate, particularly if the hammer is set to oscillate near the resonant frequency of the frame. Without very sophisticated FEA software it is hard to conceptualise just how a structure will behave. however you may find it advantages to consider the issues involved in advance and if vibration turns out to be a problem have a means of increasing the mass of the structure and what sort of damping measures you take to reduce the amplitude to an acceptable level.

Here is a link to an excellent paper on concrete filled steel structures used in machine design. http://www.mech.utah.edu/~bamberg/re...e%20Design.pdf

Thanks for the link.

Here is the comparison picture with the 3.2kw spindle. It weights next to nothing, compared to the spindle, which is a monster.



here i started to put the electronics together. No power cable in front, all go back shielded by the alu plate. Later all in metal box, due to the occasional plasma jobs.






The program i use is Sketchup, cause i am very fast at it. trying to learn also a proper Cad also at the same time. /NX9/.
