The illusive Boxford 260vmc

[Ricardoco]

Hi i2i, sorry ive not been around for some time ive been moving into a larger workshop and doing all the overtime i can to pay for it, the machine ran really well and was surprisingly accurate for its age, I will stick some video up of it working on a test piece, my filming skills are not as good as they could be, but it will show the machine working thanks to all the help ive had on this forum.

I'd like to know how you're holding the aluminium plate down in that video? Some sort of adhesive?

Ahh yes well spotted:naughty:, the aluminium plate has a 10mm edge profile but steps out to 18mm thick 50-100mm in from the edge, the mdf has a machined socket to accept the 8mm step and yes you are correct there is double sided sticky tape to hold it firmly in place together with a tight fit, this allows me to repeat the process without having to set things up each time.( i have several pieces of stock the same size and profile) I just slot the new material in the socket push down firmly and hit the cycle start button in mach3

Ok, so to begin with ive jotted an idea down in paint, there are no dimentions at the moment as i will have to base any measurements on the toolholder and the type of collets, im hoping you will all help me design this little addition with input such as bearing type tool holder type and collet type (not too expensive) the drawing is just a basic concept..

So chirp in if you have any input :idea:

Ok after a few PM's :whistling:Ive taken on some suggestions to the design like the addition of oil seals in front of the taper bearings and an oil gallery possibly for pumped cooling, and the addition of R8 collet dimentions, so any more input would be very usefull IE bearing type, coolant type, tool holder size and the such...:question:
