8 station ATC vs 6 station ATC - differences?

Post by andy_con » Fri 10 Jul , 2015 17:12 pm

in order to get an 8 station atc in a triac did denford position the tool changer differently on the 8 version so it fits?

I think it was just the tool holder sizes that determined the number of pots, 8 station were BT30 and the 6 station were BT35 :D

The machines we make now use the same tools but the holders on the 8 station are slightly smaller & the disc is slightly bigger.

ill just continue posting, even if there is a lack of help being offered ;)

ended up taking the atc arm out that holds the tools so I could CAD it up properly.

they are perfect many many thanks.

out of interest did denford make two different TR3_0767 as the centre of the two bearings on mine measures 47mm?

I am not sure. This is the 8 station version I think. Maybe a different part number on the 6 station one.

im going all out now!

by flipped the part that holds the bt35 tool in you can bunch them closer together and get 10 tools on a 210mm disk

Hi Denford fit a powered drawbar to the current VMC 1300.

It works much the same as the NovaMill and Triac.

I cant supply drawings for current machines but some of the parts are common and could be supplied.

It uses 44 springs in the chain and a similar power transmission to the NovaMill.

ok many thanks

making mountings and things is the easy part its getting hold of a decent powered drawbar setup that's the hard bit.

may enquire about pricing at some point
