View Full Version : Z slide length, dimensioning the linear system.

Hi fellows,

I've seen that the first MechMate has been given a Prismatic Linear Rail and respective unit, and I am particularly interested in that because it handles dust better than the DualVee wheels... For most applications of cutting sheet materials I think that the DualVee setup will work great but I have something a little different in mind, witch will create some serious dust amounts.


I'd like to ask for advice on dimensioning the linear system of the Z unit.

- I need the total travel to be 600mm;
- My spindle weights approximately 7Kg;
- The cutting forces should not exceed 15Kg, applied at the 600mm (maximum length of Z), and the maximum offset of this force is 150mm from the center of the Z Unit (Imagine the center line of the Z guide of the first mechmate). To make this more clear I intend to use a 300mm diameter disk and use it to cut/grind foam with it's face.

Would I be able to use only one Z linear unit, like the first mechmate, or should I make something more reinforced like adding another "slide unit" or even add another linear rail and have one slide for each rail?

any help appreciated
thanks,
Francis

Any help at all with dimensioning prismatic linear units?
