Show"N"Tell ( Your Machines) / Re: Z Axis Counter Weight
« on: December 05, 2011, 10:25:28 AM »Troy,That was my thinking when looking at anchoring closer to the spindle, as the Bridgeport type head and spindle is about 75lbs. As for the linear blocks and rails, when i got them i checked THK website and iam pushin the specs:) Thats the biggest reason iam putting a counter weight on. Take some unneeded stress off of them.
The correct way would be figuring the centre of gravity of the head and anchor it there, I think.
Regarding vibration dampening, this should not be a factor to be considered as the chain cannot transfer any substantial vibrations. The vibrations will be dampened by the head mass and also transferred to the column and base via the linear slides and thus it's important to have well preloaded linear blocks.

I think i will design counter weight to be "adjustable" , so if needed i can change anchor location. Just dont like Re - Work
Thanks,
