It's very likely Hood.   I do produce a lot of chips in my little workshop    The leadwell mill produces about 200kg a week in ally.  In fact I got a friend up here cleaning up after me!

Initially I'll probably just put a bin under it, and see how it goes.   But even on the little emco's when turning Delrin I have to empty the bugger every 10 minutes or so.   The Boxfords I want to be able to run lights out, on a few jobs I have which is ideal for them.

Here's a pic of the waste disposal chute !!   Fairly happy with the way it turned out. 

Gave me an excuse to repair the wire feed on my Mig welder which stripped all it's gears about 4 years ago!   No need to go borrowing a friends again now.

Next to make the stand which will be from 1" box section, and have a coolant tank in the bottom.

Well done Hood for at least getting it to cut something.   The old Hardinge won't be too far behind.

Watched your vid.   You running the spindle in reverse for that rear toolpost?   I'd normally run CW and use rh tools upside down.

Have you tried any real heavy cuts yet?

How are the new servo's working out?   I got one of those taiwanese AC servo's and drives here for testing, a 1kW job!

Not under estimating the Lenze motors!   I do dislike DC drives compared to modern AC drives.   It stems from the big DC spindles I seen blow up bigtime in Hardinges.

My Hardinge HXL-S (Another thread on here) had a 4kW DC drive, It's now a 3kW AC system, this is quieter and appears from initial testing to have just as much  torque.  But then it is a rather expensive Siemens affair.


The Lenze motors and the Motors fitted to the Little emco's actually make quite nice DC servo motors for the larger retrofit

Tonight I welded  the chute into the hole I cut into the bottom of the case.   Looking purposeful now!

Next week I'll have to concentrate on the Hardinge though.

Nice little vid.   Reminds me how much I hate the sounds of steppers and that DC spindle drive though!   I'm changing mine to 0.55kW 3 Phase motor and Inverter drive.   One of my TCL machines had a dead Gemini drive anyway.  I think it may have been this one I'm currently working on.

I'm quite familiar with the OmniTurns, yes Gang Tooling has it's merits on Chuckers.  I have discarded the Tailstocks on my TCL's too!

Here's a couple of pics of the Carcase of the current victim.   You can see the hole I cut in the bottom, did I say these machines were really rough LOL.   When all welding done they'll have to get grit blasted and posder coated.

Only just noticed your toolplate is a Boxford product.  I didn't know that they had thought about gang tooling.   All mine had Dickson QC toolposts on them.

We have been reviewing the collet closer design today.  I want to make it simpler than it is at the moment.  I think I have come up with a more elegant design.  But these things always need very careful testing.

I do have a collet closer solution.   Sometime ago I designed an ER32 power closer for the Emco's we run.   This I need to redesign for the Boxfords, and make a few improvements.  The emco's are shortly to be retired!

I can actually run the rapids at 7000mm/min no problem and probably higher.   But we did a little test yesterday, and the difference between 7 and 5 m/min on that test program equates to 1 second over the runtime!   So we will when time permits do more tests and find out the optimum slowest rapids and stick to that.  Anything that gives no real benefit is just worthless on such a small machine.

We are seeing it hit the 5m rapids often during that program though, even on some short moves.  but then the servo's allow much more sever acceleration.

I like your tooling plate, similar to how I intend to run mine.   How well is Mach handling the effective from and rear toolposts?  Tool offsets being used?

Any video of your machine running that part?   I'd like to see it.

They may very well get a cubloc each. depends on how much automation I eventually put on them

They should end up with magazine barfeeders, and chip conveyor, so maybe a Cubloc will be pressed into service to have that stuff.  But have to get the basic machine able to cut yet

Intended use is to put all the Delrin work I do onto these machines.  I do a LOT of delrin   Plus a couple of small mild steel jobs I do regularly.

Probably wont need screwcutting ability, but would make a useful testbed for something Brian has in mind.

Ok folks.  Here's a video of the little bugger in action.
