Upgraded Coolant Offerings

by: Greg Jackson

Both the PCNC 770 and PCNC 1100 have been offered with some very basic flood coolant options since they were first available on Tormach.com. About a year back we added the Fog Buster option, a nice atomizing spray coolant system with little fogging and small air consumption when compared to the unhealthy environment in shops using Siphon feed mist coolant systems.  That’s the coolant system we’re using in much of the video below:

We’ve heard feedback from so many customers who have worked to upgrade their coolant system, sometimes with variable success, that it seemed time to extend our product range and add more support for variations in coolant solutions that we know work well.

Documentation

We’ve started out with improved documentation on cooling, including a new four page technical document on the best way to keep the cutting process cool (here’s the download hyperlink).  To those familiar with coolant systems, we’ll look forward to additional suggestions, but please be gentle. The subject of coolant has certain parallels to religion, sports, and politics. Everybody has their own opinion and lots of very smart people don’t seem to agree on the subject. Our treatise is just a basic introduction to the subject.

Plumbing

In the past the machines have included a blue/orange flex hose that looks like the classic coolant hose solution, but wasn’t quite the same.  In order to make the system expandable the future machines will come with a blue/orange flex hose that is interchangeable with Loc-Line, the defacto industry standard.  We’re offering a replacement hose with the adapter attachment so machines can be switched over to the standard.

We’re also offering all the bits and pieces that will allow you to build a complex multiple nozzle system, sort of a plumbing version of Lego’s. Go crazy and make a blue/orange machine version of the Trevi Fountain if you like. Send us photos.

Pump

With all that flow, you might want a more powerful pump. We now have a very nice dual voltage (115 or 230) pump available for improved flow and pressure.

With the increased flow, please remember to prevent reflected coolant flow from splashing up and onto the control console on the electrical cabinet. The new pump has a very nice fit on the original coolant tank and has a draw tube which runs deeper into the tank. The deeper draw tube allows better use of the volume of coolant.

Control

Mixing flood and mist coolant is easier when there is a two way switch to redirect AC power.  In addition, pumps larger than 125W need a higher power control circuit. We have options for both of these, summarized in another recent post (Control Options).  Control options will be extended even further this year, starting with an input/output extension that will allow multiple devices to be controlled via G codes. Stay tuned in for more.

    Hi Greg.

    Very cool new video. One thing that I noticed was how quickly your PCNC1100 switches between forward and reverse while tapping. I was wondering if you could shed some light on that as when I do a tapping operation right now using a floating head, the machine seems to stall or wait for several seconds when switching direction from reverse back to forward.

    Thank you!

    PCNC Series 2 and Series 3 machines should both be similar in their ability to switch direction to what you see in the video. Our first original series 1 machines used a different spindle drive technology that was much more sluggish with respect to spindle reversals. That might explain the differences you are seeing, but I would need a SN of your machine to know further.
