Bridgeport Manual to CNC conversion...

G84 is rigid tap cycle.

You should have bought one of these.




£450 landed in UK.

No computer, no monitor, no windows license, no Mach licence, No CSIO box of tricks.

Does rigid tapping, tool changer, pendant, all built in.

These are going to be a game changer in the future.

You are reading my mind, i have difficulty expressing how i feel about each one of the BOBs available now on market, or it would be expensive, or 5v,or not shielded, or will not do this or that correctly, or ...

Ouch, nice box. Didn't know about it then though, I also like the more graphical nature of Mach3, tweaks, tricks, customisations etc :)

[Davek0974]

This might be getting there, treat it as a drill, chip-break operation, full retract, set peck depth to thread depth minus the 5mm for tapping clutch, pause before retract to allow clutch to disengage then retract.

I se for a 6mm x 1mm thread so i chose 500 rpm and 500mm/min feed should match the pitch rate of 1mm/rev ??

Only issue i see here is that it rapids out as G0, will look at that.

Sorted, the guys on the Fusion360 forum edited a post-processor so it can feed in, dwell and then feed out.

Should have it sorted nicely :)

[Davek0974]

Sub-table for the engraving spindle...



Holes A are for M10 or M12 CSK socket-head screws to bolt into the Bridgeport T-Slots, holes B are two locating dowels on the rear face to sit in the middle slot on the main table, keep it all square etc :)

25mm eco-cast tooling plate.

[John S]

Dave, once setup drop a couple of shallow keyways in the plate both vertically and horizontally so you can drop a piece of key steel in to act as back and / or side stops to get parts square

[Davek0974]

Sub-table is coming along nicely, can just be seen in the bottom of the picture, just the matrix holes to drill & tap now...



The new spindle motor fitted my adaptor perfectly, got the VFD dialled in nicely, just the water cooling to sort out.

Is this going back to the old style controllers?
Are the inputs manual or autocad? Does it connect directly to servo drivers?
Thanks

Takes standard Fanuc G-code.

Plugs and sockets on the back to go direct to drivers, tool changer, VFD for spindle, encoder for threading or rigid tapping, probe and pendant.
