View Full Version : Need Help! Clogged coolant between turret housing and turret

How difficult is it to remove the turret and clean the line then reinstall the turret? Will I run into alignment problems?

Very easy on a HIT-18S, only machine I've done. remove 4 screws that hold on cap in center of turret and remove. UNCLAMP turret, remove round slotted nut, pull off turret. I remove all tooling first to make it lighter. Note which tool is in cutting position and put it back on that way. Do not loosen any other bolts.

BNR_Randy Thanks for the come back. I started by taking the turret off (10 cap bolts). It seems that the coolant channels for each position were open (some what). Next layer down (a steel plate 1" thick) is a brass nozzle that is spring loaded against the turret for the coolant to flow through to mate up with the holes for each position. The brass nozzle didn't move but was clear. Where the problem was the back side of the steel plate (really gunk up). There is a 6mm by 4mm deep grove that runs around the back side of the plate pack with metal fines (this is the coolant channel from the turret housing that leads to the spring loaded brass nozzle).

At this point need to order a bunch of O-rings and seals (I'm there why not).

The question is there any (inexpensive) inline filter units that can filter these fines out of the coolant?

I don't know if this will help you or not, but on my Haas I use a product called Chip-Trap (http://chiptrap.com/page2.html) that uses a very effective element.
You can take one of these filters and build a dam around your pump intake.
After the present job in my HiT 18S I plan to pull the chip conveyor and coolant tank for maintenance and may address the filter issue on my machine.
