I made a gravity-fed cutting fluid feeder. I used plumbing parts as much as possible to make it easy.


I used 1.8 litre PRT bottle. The bottom was cut out and became as a tank cap.


I installed a valve to the cap of the PET bottle. Arrowed part was hose connector. It would prevent chips from flowing out.


I made an aluminium bracket to install the tank to the mill.


The bracket was screwed on to top of the column.


I silver-soldered a couple of M6 nut onto an elbow to increase freedom of installation.


The elbow was installed a magnetic base that was redundant. Hose and nozzle were screwed on it.


This shows overall arrangement. I use emulsion type cutting fluid.


Overflown cutting fluid is led to a PET bottle taped on one of bench legs. The collected fluid simply moved to the top bottle and the fluid can be recycled.


The feeder is used in this way. Not so much fluid flow is necessary and the fluid in the tank can last reasonable time.


Result of the cutting with fluid.

  • Better cutting surface, I think
  • Much easier cutting. Cutting resistance reduced.
  • Sprinkling of cutting chips dramatically reduced. Especially fine chips.

The result was quite satisfactory. I would use this always for ferrous material cutting.


  • 切削面は綺麗になると思います。
  • 送りの抵抗が減っているのがわかります。切削がとても楽になります。
  • 切子の飛散が減ります。(特に細かいやつ)


I made power feeder for my mill. So I transferred this gravity feeder to the lathe. Cutting fluid may not be used so much on lathe and gravity feeding would be enough.


I applied silicone sealant around mounting feet of the lathe to prevent the ingress of cutting fluid to the bench. The fluid would be caught by the plastic container placed below the chuck, but not so much recovered.
