DID i miss this at the BBq :-[ maybe i see this setup at the next one


Show"N"Tell ( Your Machines) / Re: 1979 Shizoka retrofit project
« on: March 05, 2008, 04:55:05 PM »

I am new to this forum. I am hoping to glean information and share in the future.

I have recently purchased a 3 axis CNC. A 1979 Shizoka STN, manual tool changer. This machine has a General Numeric 5 series controller, pre-Fanuc. Pretty old stuff!! The x axis has a problem, what I don't know. I would like to remove the controller and retrofit to a PC based control. I may have to replace the servos for compatibility reasons. I have been looking around at stepper motors and drives that would be PC compatible. I have many questions. So I will ask the most important right now.

Are stepper motors the right direction for replacing the old DC servos?

I have looked at some CNC retrofit packages but the prices are just to pricey for this machine. For 8K and over I could buy a good running machine without having to rebuild it.

Any input would be great.



Tom you will have to join www.cnczone.com and have a look at this thread  comparison of several drives , develop a professional quality and performance servo drive with hobbyist level pricing. http://www.cnczone.com/forums/showthread.php?t=38465

Hi. I am a new in the forum. I have a little company, we build the custom made equipment. One of my customers has an old manual machine and asking me to make a CNC from it. I saw you are making a magic things with machines. Can somebody help me to create right control system specifically to my machine using Mach3?

Thanks for any answers.

There are plenty controllers out there , just go to index here in the links section and you can buy complete interface electronics to do you job for the conversion.

http://www.artsoftcontrols.com/forum/index.php?topic=1177.0 seems you need  to search on this website and others there is a lot of information scattered around the WWW world.

Then there is the issue of ball screws ,  linear slides , drivers , stepper motors OR  servo motors AC or DC  the list goes on

links http://machsupport.com/forum/index.php?action=links






this is just a few of the people that can help you in your cnc conversion and not to mention the mach2/3 software ;D ;D :D ;)


PS happy reading

mmmmmmmmmmmmmm do you have a website for more information on all this testing

So from your answer , Us Australian customers will miss out on the deal of the century


Do you plan to have a agent in Australia as a distrubutor in  Australia ??


ho CNCwt

I'm under the impression this mill is sold ina few different  packages

can you list prices of all the different methods your selling the cnc_mill

what would be the most cost effective way to have a complete package with four axis also to Melbourne Australia

Time frame for machine to arrive ??? once full payment has been made ??

how much for this setup ??? your best possible price ???


i found this info on this driver  , go to there website and select English version on the left of the page , then wait a few seconds and another menu pops up , then select products , and a new pages opens up with a menu of 4 selections to choose from and select " STEPPING MOTORS and DRIVES " , then another new pages opens up and it has listed all the differant drivers , select the one your after  " SDC" an a data sheet pops up on the whole product range.

Why have you chosen this driver ? , there are other drivers out there . mo prices listed on the website so it maybe expensive ??????

the website doesn't allow direct cut and paste of the a direct link to the page


SDC is the name of a series of ministep bipolar chopper drives, suitable for driving medium-low power two-phase stepping motors, with four, six or eight terminals.

SDC drives are realized in 101 x 94 x 25 mm format and are equipped with separated connectors for logic signals and for power connections. They are designed for easy mounting inside a metal electrical cabinet, by means of spacers or brackets separately supplied by R.T.A. as an option. A type drive are intended for use with low voltage supply (24 Vdc).

R.T.A. experience, together with a careful design for these specific purposes, has led to a high reliability component, in spite of its very competitive cost.

The ministep operation, connected with a further electronic resonance damping facility, ensures excellent operating smoothness and low acoustic noise.

Opto-insulated and differential input and output signals ease interfacing with the most commonly used control systems and ensure high noise immunity.

Operation at 400, 800, 1600, 3200 and 500, 1000, 2000, 4000 steps/revolution.

Motor phase current setting by means of a DIP-SWITCH up to four possible equidistant values, between the Inf min. and Inf max. values indicated below.

Automatic current reduction at motor standstill.

Opto-insulated inputs compatible with differential control.

Possibility to switch off motor current with an external logic signal.

Protection against a short circuit at motor outputs.

Protection against under-voltage and over-voltage.

Overheating protection.

Operation with a single external supply voltage.

High efficiency CHOPPER with MOSFET final stage output.

Electronic damping facility for a further acoustic noise and mechanic vibrations reduction at low and medium speed.

Hi again

www.artsoftcontrols.com has a feature  to download film clips also http://www.artsoftcontrols.com/forum/index.php?board=60.0

sorry about the double post


hi patrick71100

What are the chances of posting some film clips on www.youtube.com , would love to see the machining process in action

Yes stevie  , make me jealous big time

love the work stevie does

keep up the good work



thanks hood for that information

OK mach3 is on the agenda , have  been corresponding behind the scenes to place a order for the hamburger with the lot
lets see how i go

any other  positive or negative feedback is welcome guys

don't be shy
