I have attached a link to a little item that I make for Radio Control Model Engines on my HAAS TM-1P.

Enjoy!


YouTube - Universal Crankshaft Locking Tool

Great video! Thanks for posting!! Always nice to see the mills in action; I appreciated the complete walkthrough of the part from start to finish.

I'm curious - when you put the fixture in the Kurt vice, it did not look like you had a fixture stop or any other means of accurately placing the fixture in the same position. Was I missing something?

Hi,

Thanks for the favorable comments on the video.

I have a Renishaw Wireless Probing system that I utilized to do the original setup to get the X,Y & Z. The Y axis was probed for alignment with the left edge of the rear vise jaw. When I installed the fixture in the vise I made sure the left edge of the fixture was in alignment with the edge of the rear vise jaw. I could have easily put a stop of the left edge of the vise jaw but found it unnecessary in this application.

Each end of the tool is used independently and the alignment of each end of the tool as they relate to each other is not critical.

I see. I just saw your Renishaw tutorial videos - those are great! Nifty system - although for $5k it should be!

I'm surprised that aligning the left edge of the fixture by hand/eye gives you sufficient alignment, especially since the other half of the cylinder has already been machined. Keep up the videos!

Hi,

Only one end of the tool is used at a time for a specific engine and only that end of the tool is inserted into the engine so there are no alignment issues. I have attached a picture so you can see how the tool is used.

If that were an issue the probe has the ability to repeat with tenths if needed. Like I said in the video the Renishaw Wireless Probe system was the best and most used option I got on my machine. I love it. Yes, the 5K hurt when I wrote the check but all is well now. Ha Ha

I just purchased a new Canon HF100 HD Camcorder so I will be making additional videos as time goes on.

Hey John, thanks for the videos! They answer a few questions I had about various things.

I'm curious about what you think about the quick code and if you feel it was worth the money? How often do you use it? Some of the more seasoned veterans here feel it's not worth the money, I would love to have your take on it.

If I remember correctly you also use ONECNC for CAD/CAM.

If you order the probe, you get quick code.

I also have a Haas and use OneCNC, the only thing I use the quick code for is Probing and tool setting!!

Do you feel the price of the probe is worth the investment? I always thought (prior to joing this forum) that it would be a must, I know how H.J. feels, what about you? :)

Like he said it's the best investment to make with a machine.

If you bought the same rig from Renishaw direct I thin you are close to the 10K range. If you talk to them direct they will tell you that even in volume they can't touch the Haas price for the system. Plus if you bought it from REnishaw you wouldnt get the fancy quick code interface either.

No more adding subtracting .1 for an edge finder tool offsets are easy to check.

I consider it a must have, unless you are a garage hobbyist who only runs the machine 2-3 hours a week.

Thanks, I'm sold on it. (again)

Hi HelicopterJohn

Great Video what speeds feeds & cutters are you using it looks like its going quite fast & thanks again for a great video

Hi mactec54,


I was machining Delrin. O.D cut was made in 2 passes with a .0005 final finish pass. RPM was 4800, 80 IPM Feed Rate with a .375 4 flute end mill. The depth of cut each pass was set at .450 with a total depth of .891.

I could have easily taken the entire depth on one pass as the load meter was hardly moving. Also I could have increased the Feed to 100 or 120 easily as the mill was not straining at all.

The chamfer cuts were at 6000 RPM at 144 IPM Feed rate.

Delrin cuts like butter.

John

......Delrin cuts like butter.

John

This is so true!

We do Delrin at 10000 rpm with 3/8" and 1/2" two flute cutters and a feed of 120 ipm; we do find flood coolant is necessary otherwise you can get melting.

One thing to watch is that you don't pull the part out of the vise or fixture, Delrin is a bit slippery.

Hi Geof,

I also cut some of the same parts with a Garr .375 diameter 3 flute high helix end mill and had excellent results. When I get a chance I will try a 2 flute. Currently I am getting a pretty nice surface finish.

I agree on the fixturing/work holding.

The fixture in the video was my first. Every time I use my machine I come up with new ideas on how to hold parts. Not being a machinist by trade listening to professionals like you is always a big help. Just an ole retired guy having a ton of fun with my CNC mill.

Thanks for your valued input.

John

Is this a machine like yours? What do these typically go for?

Hey! I have one of those black HAAS t-shirts. It was about the only thing HAAS gave out for free to my employer for buying a $150,000. lathe.

You need to run your salesman out of town. I got all kind of goodies. Guess it depends on your particular HFO.
