PCNC 1100 Series 3 Upgrade Kits now available

Series 3 Upgrades are here!

Series 3 Upgrade kits for PCNC 1100 mills are now available for sale.  The kits include 3 polyphase  motors, 3 Leadshine microstepping drivers, machine control card, and busboard.  Make sure to select the correct kit for your serial number -machines numbered 1-999 require additional mounting brackets. and should choose PN 32010.  If your mill has serial number 1000 or greater, choose PN31999.  We’ve also made the motors and drives available as a separate kit for those who want to integrate with other equipment, although those kits don’t qualify for the same pricing as the upgrade kits.

And another new product…

Sprung 5C Collets

Sprung 5C collets open up just a bit beyond nominal ID when uncompressed.  Why?  Because it can be really hard to load/unload bar stock when the uncompressed  collet IDs are size-on, especially if your trying to use them with automatic collet closers, etc.  Trouble is, its really hard to find affordable 5C collets that are also sprung – if you need one, you’re only options are premium choices with premium prices.

Not anymore.  We now have sprung 5C collets available for sale that don’t cost an arm an a leg.  Not premium, but good quality collets that are appropriate for the majority of home and small job shop lathe work.

    Will you be offering a Series 3 upgrade kit that includes the VFD spindle drive?

    Good question… The only advantage I see is so you could avoid the core return on two control boards, but that’s certainly an advantage. For now, I think we will handle this on as needed basis if you order both at the same time.

    Andy, Just to say that I completed yesterday the series 3 upgrade and I am very pleased with the result. The process was straight forward with the instructions being clear and comprehensive enough.I took your advice and decided at the same time to set the Gibs on all three axis so the total time spent was aproximately 1 day.

    The difference with speed and quietness from the steppers was really very marked.Initial cuts appear to be more accurate as well. So thumbs up for a good upgrade offering.

    My regards Simon
