What are folks using to balance the delivery of way oil to each dovetail? I noticed I am getting much more oil flow on the side that is closest to the inlet where my automatic lube is plumbed in. Anyone make cheap miniature flow meters for 4mm diameter tubing?

Affordably they all come from Hong Kong on Ebay. Sometimes you can find them in the states but for 2-3 times the price.

check bijur metering devices. available ebay and else where. i have one on every lube point and seems to work well. they have compression fittings for 4mm or 5/32 tubing.

I got all of mine from Arc Euro Trade.

Even after paypals high currency exchange rate, it was still half the price of trying to get anything here in the states.



All of mine was name brand, Bijur

Attachment 267644 I'm using one of these with a microcontroller and small "rattle" type automotive fuel pump. the microcontroller meters oil one tube at a time and each for a user specified pulse-width. Ultimately the plan is to monitor the accumulated distance on each axis and oil periodically to the ways and ball-nuts. I have one similar to the picture that I picked up for under $60.00 on ebay. It uses 6mm lines to the ways and an 8mm line to the source. The machine is undergoing the CNC conversion and unfinished right now so I cant yet provide any performance results.

I'd really like to know more of the details around this solution. It sounds very interesting!!

Hopefully I am not derailing the OP thread by expressing an interest.

Personally, I am planning on using something like this

109 , that is a nice metering valve. Or the price is.

[Nigel Tufnel]

Thanks for all the great options.

Anyone ever use valves like this?

They work great, I have several on my mill.

Those work great on the air cylinders too. As they were intended.
