Anybody know anything about these turret drilling machines? A friend asked me if I wanted it and although the workshop is pretty full I am tempted to make some room for it. I believe this may have been made by Metabo a Spanish machine tool company that also built clones of the Deckel FP1,and Thiel type mills. It has no 'moveable' table but could be adapted for a bolt on x-y table as long as it was low enough. It is well built and sturdy and too good to scrap out, plus it has a goodly collection of tapping heads (not the retainer plate of the one tapping head on the turret currently)

It looks like a clone of the US made Burgmaster.

It does not look rigid enough to use for milling, if that is why you are considering an xy table.
But could be handy if you had large numbers of holes to drill and tap etc. Otherwise, hard to see any great advantage over a regular drill press.
Tis pretty neat though.

Wouldn't use it for milling as I recognise there is little sideways support in what is essentially a drill, I already have an Aciera F3 and a Bridgeport for milling so no worries there! It is an interesting 'Production' set up as opposed to a 'gang' of bench drills which is the more normal approach to multi op drilling and taping. The x-y table was more to do with an attempt to get some accuracy in co-ordinate drilling of multiple holes - but on second thoughts it is probably easier to 'mark out' and pick up centre spots. I'm considering using it for crankcase drilling and tapping, which will need a minimum of 12, and upto 24 holes drilled and tapped, with corresponding clearance holes and spot facing.
One area which looks to be well thought out is the depth stop system for each individual tool station, as indexing the head turret also indexes a stop bar. The other bit of trick design seems to be that the turret head is programmable for speeds as it goes from station to station - but note that stations have explicit speed ranges.
Do you have any information on the Burgmaster that you quote John? Looked on the usual Lathes dot UK site but neither the Manamas nor the Burgmaster are listed.

I have seen one before, but cannot remember where, one of the frustrations of getting old.

Ah. Sounds ideal for your crankcase drilling if you have the space for it in your workshop. You can always sell it off if you get sick of tripping over it. ( LOL I have half a shedful of those machines.)

Burgmaster went under in 1986. There is a history of the company on line if you do a bit of light Googling. Not seen a Spanish copy before, though the online history says that Burgmaster did a licencing arrangement with Yamasaki (Mazak) that seemed to hasten their demise.
There was a UK importer / agent. I can't recall the company name, but did work with them around 1983/84, when my previous employer worked with them to make one into a CNC drilling machine. They did the mechanical mods (ballscrew to replace the star handle feed & an X-Y table, all mounted on a fabricated base. We supplied the electrics & a Heidenhain TNC131 point-to-point control. The machine went to a pneumatic valve manufacturer in southern Scotland. IIRC there was talk of doing another, but it didn't come to anything. On the original machine the turret index was achieved by driving the head assembly upwards until a fixed bar on the frame depressed a lever on the head. This diverted the motor power to an index mechanism to rotate the head one station. On the CNC version the head was retracted to theZ axis reference position & an M-code controlled solenoid pressed the index device on the head. There was no turret position feedback, so the programmer had to keep track of where the turret was & add a number of M-code calls at the end of the program to skip through un-used stations to return the first tool to position.

Yep! I know the feeling, I suffer from the same all the time - usually it is 'where have I left my glasses?'
Thanks for the information - this machine was originally supplied by - DEC (Coventry) Ltd, of Manor Road, Atherstone. I do not know if they were the importers or just agents of the importers. I did find a couple of references to Masanas on the 'tinterweb' which showed a similar machine for sale in Spain (apparently it's a model TR1). They look to have been building these at least as the late 1990's. This one dates from 1987. On the Youtube site there is a Burgmaster which has been adapted onto, what looks like, a Bridgeport base (replacing the turret head of the milling machine) to provide it with a very adaptable x - y co-ordinate table facility. It is shown drilling the end plate of a steam tube boiler assembly!
The more I look at it the more I fancy 'that it will come in useful one day' - now where have I heard that before??
