I use Mobil Vactra #2 way oil on my 1100 since 2007. I always lubricate the Z-axis ball screws and ways by hand by lowering the z-axis all the way to the mill table.

I cut holes for 4-40 screws in spring tempered 301 SS using a Hi Roc solid carbide 135* split point carbide drill bit and Mobilmet Omega cutting fluid....
I use a left hand boring bar in a boring head on my 1100 . On a hole the size of 1/2" diameter I drill first then bore undersize with the boring head then using a floating reamer holder ream to size....
On my 1100 after roughing a round hole out by trepanning using a 1/2" endmill, I finish by boring using a single point tool. The roundness is then determined by spindle runnout. I have done this for...

BUMP the main point was that for precision holes I don't rely on drilling but use the boring head and single point bore the hole.
Don
For locating pin holes I first drill then single point bore and then using this floating reamer holder I built using a 3/8" TTS holder ream to size.

Looks like a Kurt D688 vise. I added a subplate underneath the D688 and freed up an inch of Y-axis travel from using vise keys on the middle slot with only the vise. Also I machined two removable...
Set the WAYBAC to the 1980's when Westec was held every year in DTLA at the convention center with the gigantic night sky star map inlaid on the ground floor. Tap Magic had a demo where one could...
Exactly. That's what I just did tapping a 4-40 hole in a SS part. Had plenty of head room this time but since this is a one off part and difficult SS material I used the Fisher micro tap guide in a...
I do it all the time with my Procunier tapping head with the 1100. I have tapped 10s of thousands of blind 4-40 holes really fast with the Procunier tapping head on the 1100 and lots of 2-56 blind...
Yep I thread mill on threads greater than 1/4 or M6. For aluminum and smaller threads like 4-40 I find Balax form tap in a Procunier tapping head works extremely well for me. Not only are the...
Tapped a single 6-32UN hole. The real issue was how to hold a large odd shaped part and locate, drill hole, and tap the 6-32 hole. My solution was to use the same fixture made to hold the part...
Fusion makes you put your work on the cloud. No Thanks. Also I own SprutCAM software not borrow the software like Fusion and are at the whim of Autodesk.

Well I don't use FORTRAN IV on 80 column punch cards anymore like I did back in 1971 nor DOS though. However Gcode hasn't advanced that far from it's paper tape beginnings ;-)

I am still using SprutCam 7 bought back in 2007 along with the Tormach. Also own Solidworks 2010. I also don't like subscription software or software that has you put your stuff up on the cloud. I...
Before I got the PDB I had purchased the 31217 Spindle Door Latch Upgrade which for me has always been sketchy....
While I normally trepan nowadays on the Tormach using an end mill I recently trepanned old school on my manual lathe. Trepanned a 6.25" diameter plug from 10" x 1" 6061-T6 round on the lathe using a...
I also use the Bison 5in 3 jaw with reversible jaws with DIY adjusta-chuck on my lathe with the 5C closer. BTW I use soft jaws I make in the Tormach on my cheap chicom 6" 3 jaw.

I have a vintage Buck adjust Tru for my lathe.

One has to touch the Mitutoyo 950-111 with a hardened tool to work? The thing I like about my tool #1 Z-height tool is that I measure the height of this tool offline on the surface plate in a Tormach...
This part used every inch of Y travel so there was really no room on the 1100 for more than one of this part at a time. I don't like using a corner of the fixture as I use an edge finder that is...
All the links on Tormach's web page to SprutCAM tutorials are broken.

Yep a by roll tap I mean forming tap. Thread Forming vs Cutting | Balax | Forming Taps, Cutting Taps, Thread Gages
One still has the problem with either a form tap or cutting tap in tapping in...
I use a combination of MDI and the jog shuttle controller.
Don
I owned a set of Tormach T/C tapping heads and found that compared to the Procunier head in tapping BLIND holes with the Tormach the T/C heads are way too slow. I sold that set of T/C heads. It would...
The jog shuttle works as well as hand wheels for me on my 1100.

This week I tapped about 800 blind 4-40 holes 0.25" deep in 6061-T6 using a Balax roll tap in a Procunier 1E tapper on my Tormach 1100. Spindle running at 1200 RPM, I feed the Procunier at 100%: ...
Used to have a Blake type center finder. I don't like the idea of sweeping the probe under power so I built my own center finder using a Daedal ball bearing positioner with an Interapid Vertical TDI...
