We currently are using a few Haas mini mills and are looking for a better way to touch off our tools. We currently use the old fashion piece of paper touch off method. Enco sells a tool setter from Fowler (http://www.use-enco.com/CGI/INSRIT?P...&PARTPG=INSRHI ) I didn’t know if anyone has used the Fowler tool setter. I have seen tool setters from $75 to thousands of dollars. Can someone recommend a good tool setter for a CNC Mill that is cost effective and durable? We will either buy 4 tool setters or use one for all four of our centers depending on cost and flexibility.

Thanks,

I have found no tool setter to be more accurate or less expensive than a stack of Post-It (TM) notes. I buy the generic ones from the local office supply store about once a year. I think it costs somewhere around $5, and there's no maintenance to worry about.

You can make your own with a Dial Indicator.

Mine costs $90. Federal Indicator .0001 resolution (bought at pawn shop 10 years ago), Material and Hardware.

A stack of Post-It notes is certainly an interesting method I'll have to try that now. Just out of curiosity, what does a stack of 'notes measure?

BTW, before I bought my Starret I used a basic 1-2-3 block to set heights. I don't know what they run nowadays but it worked well for 7-8 years. I would start with the tool below the top of the block and job up 0.001 at a time until the block slid (gently) underneath. For greater precision I would record the Z then make a negative approach to the block (down) 0.0001 at a time until the block would not slide in.

I much prefer the Starret

That's pretty slick Toby

There is something similar to what Toby shows on the Industrial hobbies website.
The other way is via some electrical/electronic means.

I purchased a probe from Wildhorse innovations and it comes with a tool length setting top.
IMserv also sells one.
For Mach3 users there is a great write up about how to use it and custom screens .

My BTC-1 has a 24 position tool changer which will be integrated this winter. I will be testing out the probe for edge finding and for tool setting. At about $100 each if I like it I will buy a second one so the tool length setter can be permanently installed on the table.

I am not sure if you Haas supports this type of probe and tool setter but to automate the process makes a ton of sense especially in a production environment.

Mike, I am thinking of purchasing the same thing from Wildhorse Innovations. How do you like it and what size is the ball on the end? Hard to tell from the picture on his website and no spec's. I am going to use with a IM Service 12x24 router system so hoping the stereo plug works without rewiring. BG

I made this at home because the shop I was working at was using a lot of CBN Miniature End Mills from Harvey Tool. They cost $221.00 for a .6mm to $235.00 for a 2mm. The other guys were chipping the tools on touch off with paper and plastic shim, so I made this to eliminate the chipping.

The Body is 17-4PH, the Foot is Brass 360 Half Hard, and the Calibration Dial on the bottom is 17-4 PH as well. It was fun to make.

It is pretty slick, but not totally my idea, it was modified from someone else's design.

Considering that you can touch tools within .0001 it is great for when you have to blend pocket floors and hold Tight Tolerances.

I can't take all the credit for this, but thanks.

Well... As soon as my router support surface block/tool setter to do automatic length correction, it would be stupid not to use such convenient function... I'm using one made by myself for more than half of year and am happy with it. You can find it on Ebay item #160387750380 as well.

It gives resolution below 0.004mm which is more than enough for my applications ;-)

For reference:

1 Post-It (TM) note is about 0.002" thick measured with Made in USA digital micrometer.

It gets close enough for most of my work.

Toby, I have seen a similar product to what you built, but I think I like yours better. Nice work.

Thanks for the compliment

Nice stuff

Anyone have any idea how to rig up something with a dial gauge that is 0.125 thick?

This is what I have used the last 10 years. It has set my Z within .0005 every time. I've seen it for $99 in some of the sale fliers. the best investment I've ever made for setup tools at least. I have never bought anything from wttool so I couldn't say how there service is. I believe I got mine from TSI. DO NOT BUY THE FOWLER ONE!!! another guy I work with got one and it is a piece of crap. The one I have is spring loaded so if you come down a little to much or to fast no harm (the fowler is not!). you will have tool marks within a month of use and soon you will be searching for a spt that isn't all mahrd up. I guess that is why they make the contact surface so large.
