Mist Coolant Project

[johnsattuk]

A peristaltic pump with a stepper gives you positive and predictable fluid delivery, no pressurised containers with pressure settings, needle valves, fluid viscosity and so on to upset the balance of perfect lube volume delivery. :D

Couldn't have put it better myself

We really need a "Like" button! :D

A couple of years ago I started a thread about printing my own peristaltic pump. The intention was to follow through with a controller for coolant and air. The project was shelved through illness and now I am better I am picking up on unfinished projects.

I have all the kit I need to make a step programmer that at each step delivers air, coolant or both. I thought about 16 steps at first, but that is way OTT so 8 channels.

I will carry on with it one day, but I have other projects to clear first.

The reservation I have is that peristaltic pumps need a soft silicone tube. I have been informed that silicone tube is not oil resistant _ any advice please !

Cheers

I'll let you know about Oil and the Silicone Tube.

On oil introduction, the oil is introduced into a sleeve concentric around the air tube, the oil sleeve is shorter than the air tube and it's position can be adjusted to tune oil delivery but essentially the oil is always introduced after the air leaves the nozzle.
