Angle Dresser

Angle Dresser
While working on a new tool to be posted in the forum I came to a point and discovered I didn’t have a way to do my next step, so that put the brakes on that project for a few days, I want get into details about the tool I was making just about the tool I have to make to complete that tool.

95% of all the tools I make are finished on the surface grinder, surface grinders leave a beautiful finish and you can work with in a gnats asz, I’ve always been able to setup my work for grinding on a magnetic chuck, parallels, blocks, tool makers vice, or a fixture of some kind, well this time I couldn’t set the part up at a 45° angle on the grinder due to its size, so the only way to grind the 45° angle I needed was to make a tool that would dress the side of the surface grinder wheel at 45°, shops I worked in over my years had an angle and radius dressers, those things can cost you an arm and a leg, I don’t need the radius dressing capability just the angle dressing feature, so over the weekend I came up with this design.

I wanted to make this tool simple and easy to use; this angle dresser does not have pins set at a certain center distance like a sine bar or a sine plate that require the use of gage blocks (which I have), all Iuse is a simple 45° angle plate to set my angle and lock it, most common angles can be readily set using any angle plate.

I make most all of my tools from 4140 steel and heat treat prior to grinding, I didn’t have a couple of sizes of 4140 that I needed so I made the entire unit from 1018, I was in a hurry so I just made it from mild steel which will work just fine, it has been ground all over and looks good and functions as intended.

The diamond is guided by a tongue milled on the upper part of the dressers body while the lower body has a slot, making it have sort of like square ways or just plain old tongue and groove, there is an adjustable friction plate mounted underneath the lower body which secures the two body parts from separating yet letting it slide smoothly with just a very slight drag, the diamond is advanced by means of a left hand threaded screw, same as the cross slide on a lathe, I’ll be posting the project that this tool was made to help complete in my next post.

Below you will find some photos of the completed tool along with some photos of the machining process and a video of the tool dressing a 45° angle on the edge of a surface grinding wheel.

As always thanks for looking
And happy machining
Doug

Nice job Doug, very useful tool to extent the range of your grinder ( a surface grinder is the one machine I really miss having use of).
Thats an expensive diamond you are using there, and I noticed a permanent magnetic chuck for which I assume you have a demagnitiser in the shop.
I made one from a microwave transformer which works well.
Thanks for posting.

Doug,

Wow, very nice tool. You are an amazing toolmaker with your finishing work on the surface grinder.

Paul

Thank You Paul
Your pretty amazing yourself, I like your work as well

Very nice job Doug. This was tool of the week for me....
Brendon

Thanks Brendon,
That was very nice of you to say

awesome tool you made doug

Thanks for the compliment Dan
Yea I have a demag, but now you have me intrigued about the one you made from a microwave transformer, I would like to see it and understand its functionality if you don't mind sharing

Thank You ragsflh

Thanks Doug, I will give it a go at posting the demag but this is not my area of expertise.
I think I picked up the idea on the web somewhere and copied it monkey see monkey do fashion without fully understanding why it works.
No doubt after posting someone will explain the theory.

Olderdan

Sounds good Dan
I'll be looking forward to it

I used to make Fluidmotion Wheel Dressers at J&S Tool Co. You should get one of those someday. I could even tell you how to rebuild an old tired one, I think? It's been quite a while since I've done it, but I remember the broad strokes still. Enough of the process that you could probably figure out the rest. There is one odd piece of equipment you need to do a rebuild though. You need a rotary air table. You use that to resurface the base. But most of the rest we just did on a plain old surface grinder. Well, there is one critical part of the process that I don't know offhand. I don't know the diameter of the test ball we used. I mean I just used the things we had laying around. But thinking about it now I bet the size is pretty important. I suppose if you understood the geometry the size could be calculated? OK there's two odd items you need to do the build. Because I honestly don't know where you'd get one of those test balls even if you know what size it was. It was a carbide ball mounted on a stud that a diamond is usually mounted on. That's how we inspected the units. We'd mount the ball in place of a diamond and indicate the surface of the ball. If we could sweep the unit through its range of motion without moving the needle it was good. Neat huh?

Sounds interesting pfredX1
I bet those things were very consistent in movement and highly accurate as well, but the one I made will work fine enough for what I do, just setting it with an angle plate will be close enough for what I'm doing, I make all my angle plates with the aid of a sine bar and gage blocks and I can get them down to the nitty gritty pretty darn good,

Would be an interesting tool to see though

Thanks Doug

Congratulations rossbotics - your Angle Dresser is the Homemade Tool of the Week!

Congratulations Rossbotics. You beat off a strong field to win this week
but like I said previously, your angle dresser was tool of the week for me....
Keep up the good work.
Brendon

Thanks Brendon, Much appreciated
You know how sometimes you feel pretty confident about something? well this win I didn't feel that, to be honest I thought for sure your sled was going to win, that's where I had my money, of course the other guys had nice projects to but I was betting on you, you keep up the good work yourself as well

Doug

Well deserved. Congratulations.

Hey! Doug,
I too, thought my sled might have had a chance, particularly given the link to my blog and the detailed post I did on calibration etc.
We always live in hope I suppose.
But you know, I got beat. That's the way it goes. There was stiff competition this week for sure.
You're a damned fine machinist Doug, there is no doubting that. Well done and enjoy the moment.
Brendon

Well deserved Doug, I could see this coming even if you didn't.

Thanks Dan, your right I didn't see it coming

Doug

Are there plans for this dresser available to buy?

Just uploaded the plans, there located at the bottom of my post beneath the video

Thanks much.

I am amazed how all your tools look so beautifull. I know that you are very experienced. But still. 😊

Thank You Very Much Tuomas
Many Years
