Re: Proxxon TBM115 on it's way
|
I have a Proxxon TBM115? and it has served me well on drilling hundreds of PC boards at my fabrication shop.
There are definitely better drill press setups available. But prices do get high.
I would recommend buying the drill bits for PCB drilling. These are the ones with the colored collars on them that you see on ebay and amazon and so on...
Check the belt tension also, and monitor how hot the spindle area gets, the belt does not have to be super tight, my spindle gets pretty warm after a 20 or so boards of continuous drilling.
Some light synthetic oil or sewing machine oil keeps everything lubed up in the spindle area. A good light shining on the board helps a lot !!
Also, at the junk store I found a respirator pump (?) it's like a little air pump in a plastic case, blows a constant stream of air onto my drilling area to keep the area clear of dust.
The big thing is not to let the board jiggle or rise up as the bit makes contact with the board, that generally breaks the bit (in my case) as it puts a bunch of force against the side of the bit.
Have Fun !
