General Mach Discussion / SERVO motor

« on: July 03, 2010, 02:33:20 PM »

I've decided to build a third CNC machine, but with servo motor.
i have 3 AC servo motor with Specifications :
1-Analog
2-speed control
3-about 400W  1.3N.m 3000 RPM

now i have two questions:

1-my motor are analog, and I can not use them without intermediaries( i mean :converter digital to analog) .i want use "KFLOP" .
  i see in specification  > """ 8 Channels Servo Drive Analog Outputs, Range ±10V """
  I think it is a good choice.
  Whether there is another choice?

2-Considering the fact that these motors are Speed control ,I can use them for router machine ? Whether they are suitable ?

thx Terry and Stirling
I think that this Draw type is not common.This example belongs to my customer and for this purpose complex that is less losses.
If I'm not mistaken, should polygon with take apart.
when i import this Draw to Sheetcam ,It can be confusing ,And to spread to Mark(my mean is S number). this is master problem.

Many of my customers are men selfish and want to have slight losses but I think that is not logical.
Please guide.

Show"N"Tell ( Your Machines) / different design

« on: June 30, 2010, 04:18:52 AM »

A few months ago, I bought a machine called chip mounter(image No1) and start the dissection.
I saw the pieces of aluminum that you can see it (image No2)
i decide build cnc with This machine accessories.
To do this I need your sympathy.
Y & Z axis are already complete.( for my chip mounter )
i want design X-axis for it.Similar image No3 .I think the design is strange.
can someone explain Mathematical calculations? and help me in during build this machine.
Please tell your Opinion about design so I use them for better design.
