Hello Steve, the head angle on the T&C should be 1.5 to 3 degrees higher then the helix of the tool. That will generate a parabola curve which will create the rake face. The radius tangent point on the side of the wheel will be the point of rake generation. The core radius is impart created by the parabola sweep of the wheel radius so the radius dressed on the wheel should be roughly .06 times the diameter of the tool you are grinding. The wheel position should be offset from the center of the tool by taking the SIN of the rake angle desired times the radius of the tool diameter. Most HSS roughers have a helix angle of 30 to 35 degrees for steel cutting and 36 to 45 degrees for non-ferrous materials. Rake angles for cutting steel are 8 to 12 degrees and 14 to 18 degrees for non-ferrous. You should also be using a 1V1 style grinding wheel with a steep angle for flute clearance. I still need to put a package of tools together for you and I have a few of the 1V1 wheels I can send you. I'll try and get that out to you soon. Was great to see you at the Bash and keep up the great work. Dennis
I was waiting on you to comment Dennis😁 That all makes sense. Huge thanks for taking the time to explain what needs to go on. It's not the easiest info to find if you dont know where to start looking. If I would have thought I should have just contacted you to begin with. I just messed around till I had something that worked the way I thought it should and looked ok😉. I'll be saving your response for reference. None of the books I have cover grinding roughers. Thanks again and take your time on the endmills, I know your a busy guy.👍 I took a screenshot of you comment. Do you have a grinding book you could recommend?
I've been a tool & cutter grinder for 27 years. Years ago I found a VHS tape of a machine for roughers. I used that to come up with my own setup with what I had. I use an old Pratt & Whitney R6 radius grinder, which has multiple axis, with a Weldon air bearing on the table. I use a adjustable tooth rest on the back of the tooth, which can feed in as another axis. I use a 4" x .140 CBN 1FF1 wheel. I swivel the base to about 1° more than the helix angle. I use the different axis to generate the profile of the factory flute. It takes a bit of practice to learn how to move to achieve the profile you want. I've done a few thousand over the years with no complaints. cuttingtooldesigner is giving you all the exact specs for how it all works. I am giving you just what my simple setup worked for me. You did a great job with what you had to work with.
I remember bringing in the garden each year growing up. The freezing and canning would go on for days. Back home, everyone had a basement or something similar where we stocked canned food up and potatoes
Steve I have sharpened hundreds of those ,I used a Weldon air bearing fixture it worked great.i got printed lit from the company that makes the em,they Showed using a 6 inch dish wheel with the head turned a little more than the helix angle and you match the grind on the em and grind till the wear land is gone.i sharpened all sizes and never had a complaint. Mike
Hand- eye coordination with simple fixturing can go a long way towards success. I sharpen Carbide tipped saw blades mounted on my radial arm saw with nothing more than a cheap diamond disk chucked in a Dremel and mounted on a board and just kiss the tooth face, no measuring or stops, 10 minutes later I'm smoke- free cutting again. ☺
Good job Steve... boy that roughing mill worked smooth... You were taking a ton of material and it just plowed on through smoothly... Thanks for sharing
Love your videos Steve. Love your vegetable garden. As far as sweet corn goes. My favorite is Silver Queen. To experience the true sweetness of this sweet corn. Grow it yourself. Have a pot of plain water boiling before you pick some ears. Right after you pick it. Shuck it and get it into right into the boiling water. After 10 minutes. It’s ready to eat. You will be experience by far the Best FRESH Sweet Corn ever. Besides being extremely sweet, it also actually tastes like Corn.
I wish you aswell as 98% of my favourite RUclips channels creator's would not apologise for living there lives especially on a video that is still on time and appreciated even if it was a week late. Your as human as my understanding of life's difficulties and I don't have a family or a demanding job or channel to with more subscribers than is comfortable to count in any given day. So Steve I'll put my neck out and say for everyone that watch you that we just want you to be comfortable with your workload and make sure you put your family, and work first, we understand even a few clips sewn together that is 3mins long is OK. Although it's amazing of you to care and say but hope you take this on board a little to help you from stressing out in future if it's completely impossible to upload on weekend. respects Alex
Wow that thing hogs! Looks like you have another skill in the arsenal. Looking at where your shop and skills are today vs just a few yrs ago it's quite remarkable how much your capabilities have increased. Keep going!
Morning Steve great content I don't know how many times I've done what your dad had you do with the wood shaper cutter, for me it was a time saver to cut one than to grind one up, the profile was always consistent omg man that takes me back to 1985 in my architectural cabinetry and trim days
Nice episode Steve! As always, I really enjoy the machining content and also the outdoor activities. Corn harvest turned out great this year! Cheers bud!
Steve, I like the way you approach and figure things out as you go. I ground those cutters for years.... Good job! In the future try and use a 15v9 dish wheel... And if you ever try a Norton SG wheel you'll never go back to regular white aluminum oxide wheels. I used to hand sharpen on a Harig air bearing fixture... Freehand with a Norton .007" wheel.... You won't believe this wheel!!! I tried the finger as a guide several times but the free hand is much faster and with a keen eye you can get flute depth really close. I always figured it's a rougher that will be followed by a finishing end mill anyway so it didn't have to be absolutely perfect. I never had a rougher come back. Please be careful with your hands so close to that wheel... One mis cue and that wheel could zip that end mill in really fast and grind a gouge out of you in a hurry... I've done it. Great video... I can hook you up with plenty of grinding stuff if you're interested.... I will never do this again so it's just wasting away in my garage.
Steve - you did extremely well without an air spindle. The fact you were able to do that without one, is laudable. The last shop I worked at, only two of us would do this type of grind - air spindle with no finger! I like the test cut you did. I owe you some diamond wheels, don't give up on me, I will get them to you eventually. Do you have plenty of 1-1/2' shank cob mills? I have buckets of them....... nice work on the K.O. Lee.
Another great video Steve! I am especially interested in your grinding videos because I have a small grinder that I have not used much and haven't found a lot of good basic information like you show. Thanks!
Nice grind Steve. The proof is in the chips eh. That puppy really did pile them up. No complaints from the mill either. Great post on everything from you today.
Steve, I would enjoy seeing a video on the relationship between you and your dad. You give him some cameo time, but I would be interested in how and what you learned from your dad and what you are still learning from him. Is he a wood worker hobbiest or was he a career wood worker?
Hey Steve good video....I started my machinist career working in the dry grind department of the Brubaker Tool Co. sharpening milling cutters , and still have friends that work there, my one friend after working 30+ years just told me a few weeks back he thought that the air bearing fixtures were junk... and I think they said they don't use them anymore...just passing that to you ...
Hi Nice view of the oil filter. You might consider a finer filtration method. and adding a magnet to collect what passes through the OEM filter which in my mind is a screen. Abrasive particles will pass through the filter. Thanks
Yeah Brian, same deal with spiral flute taps. It turned out good for a 1st go. It was the same thing when I tried to sharpen regular endmills in the beginning. Fumble my way around till I get the proper method figured out. Hope all is well over your way.
It is possible to grind a rougher with a hand grinder. The worn tooth has to be taken back so the wear area is removed. If you study the worn cutter first, you will see the gullet between the teeth doesn't contact your work, only the tip of the tooth. It does take some time and ability but you can do it without an expensive setup. Another bonus is that the tooth length can be uneven and have very little effect on the cut. I usually cut with the lowest part of the cutter, sharpening as necessary and using a cutoff wheel to remove that section after it is used up. A good analogy is sharpening a chainsaw tooth, take it back to remove the wear and provide an angle to allow it to curl your chip. Also, use flood coolant if at all possible to remove the heat, the chips should always look like this video, never discolored.
I can name three guys right off that could keep you busy for a couple of years. Adam, Bryan, and Keith, right? (They don't sharpen - just collect.... ) 🤣🤣 Good video.
Good job on grinding the rougher. I just noticed that in your first sequence, you seem to grind on the way "out" of the helix, but on the second segment where you explained your setup you seem to grind on the way in and then raising the wheel. Does it work both ways?
You can save LOTS of money buying broken and dull end mills and other kinds of cutters on eBay. You can sometimes get $100+ bits for under $5. With your skill you could make them like new.
Did you have to debur the flutes? How did you determine the helix angle? Trial and error? I got a delta toolmaster grinder with a bunch of accessories so I am watching your progress with great interest.
I was just doing that yesterday with a dremel. I don't have my tool grinder up online yet. Nor do I have the accessories as well to do it. So I tried with a dremel, sized the stone for the groove. Haven't tried it, noticed that I had to turn the dremel toward the shank to avoid it wanting to roll over toward the outside cutting edge, so now it pulled toward the inside... Probably failed as it's a hand held job.. we'll see.
I imagine that it's extremely tough to get that indexing finger to engage in the exact same spot every time. I think that a much smaller grinding wheel would have allowed for easier clearances along that helix. Something along the lines of 2" diameter. That cutter grinder is an awesome little machine, but the setups probably require the patience of Job. It's like a 3d jigsaw puzzle to imagine the angles and clearances.
I found that using a serrated knife works better for cutting corn off the cob.. I place the cob vertically in a big pot and push the knife down.. It gets everything there is to get...Mike in Louisiana
Hi Steve What oil did you end up using in the gearbox of the K&T? I am almost ready to replace my gearbox after a recondition and want to use what is best Thanks in advance. W
Your're lucky not to be cursed with 'rusty fingers', perspiration can be highly corrosive, and the degree of corrosiveness varies from person to person. Great video, BTW, when y'all gonna make a nice drop o' 'shine from some of that corn? Best Wishes from Somerset UK.
Heat bluing is easy and a heck of a lot cheaper than using tool black that is for sure.. A quart of tool black is going toward 100 bucks lately.. Mike in Louisiana
I learn to graind end mill a long time ago the first shop i started in had the machine no one knew how to use it i had learn how in school so I would sharpen the emill in shop trued to buy the machine when the shop close
Grinding cutters we like this work. Happy Saturday and a wonderful 3 day weekend it is Labor Day weekend. now lets sit back and enjoy the video. Thank you for the close up we see you ground the cutter well, it is sure must be nice to be able to do your won grinding especially on those larger roughing end-mills. 8:30 is a good understanding Steve. Heat bluing came out really nice. Lance & Patrick.
I just got Jones & Shipman 310 cutter & grinder (looks like 1950s or 1960s no picture on the net seems to show one just like mine) but I don't have fancy motorized nor even sensitive work head - just end mill grinding attachment (air bearing) and sine vise and lathe bit attachment. Not sure whatever anyone here has extra accessories they could part with. I was thinking of using a rotary table vertically with a center as my work head for plain horizontal mill cutters where clearance angles are not to difficult.
A one gallon jug of the Koolmist goes a really long way. The air blast does most of the cooling, the liquid lubricates and cools. Most guys that I see using them, use entirely to much air. I setup a mini pressure regulator on mine, I can run it with as little as 45 psi to reduce the compressor cycle time and the amount of coolant required to do the job.
Steve, "The Kutter Grinder King". It appears you use windshield washer fluid with your mister which is a "cool" idea. Rust does not show up well on darker finishes so the heat blueing is a good idea. Out of sight, out of mind. :-) "Oh fudge!" The complete lack of Ave language puts Steve in the same gentleman category with Jim Bollinger, Keith Rucker, Jody Collier, Joe Pieczynski, Brian Block, Steve Saunders and other highly respected RUclips creators.
@@SteveSummers You are not planning on painting it in that dull machine gray color, that's on the handle are you? Its always sunny in the shop, and La Cem have pimped their lathes out in style. It´s essential to come up with a spectacular signature Steve Summers color, to set it apart from the rest of the youtubers. :)
@@SteveSummers I have similar horizontal mill - do you think painting it with old paint on and filling in holes and uneven paint with Bondo would look nice or is just waste of time? Dissembling it all and cleaning mountains of paint is too scary for me.
You'll do a lot better with cutting oil in your K&T...I have three with oil in them.. All three had soluble before I got them.. Seized coolant pumps, garbage in the sump, etc. Oil is plug and play.. You go away for six months and when you get back to your machine you have oil not some form of dead decayed stuff in your sump.. Cheers! Mike in Louisiana
at 5:46 if you are NOT using the ear plugs PLEASE take them off, around the spinning mill cutter it is dangerous, can suck you in and take an eye or other part of your body perminently out of commission.
drop a neodymium magnet into the KT filter pocket.. that will catch all the metallic debris and keep it out of the bearings.. i put 4 or 5 stacked most rear ends and the oil does not change color even.. the magnets get covered but it keeps it out from between the bearing rollers.. i.imgur.com/9O0M4JN.jpg?1 like that..
Excellent grind on that big hogging end-mill! (By the way, did you see High Speed Steve move across the screen whilst you were testing that end-mill? ;) )

You learned all this yourself ? You did good . I was a tool and cutter grinder for 31 years
Thank you. Always wanted to know how that was done.
Nice! Helluva way to save potentially hundreds of bucks🤑.
Nicely done sir!
I guess a similar method is used for sharpening taps right? You got it to cut and not burn up so I would say you did good! :-)
Yeah Brian, same deal with spiral flute taps. It turned out good for a 1st go. It was the same thing when I tried to sharpen regular endmills in the beginning. Fumble my way around till I get the proper method figured out. Hope all is well over your way.

You can save LOTS of money buying broken and dull end mills and other kinds of cutters on eBay. You can sometimes get $100+ bits for under $5. With your skill you could make them like new.
Did you have to debur the flutes? How did you determine the helix angle? Trial and error? I got a delta toolmaster grinder with a bunch of accessories so I am watching your progress with great interest.
I was just doing that yesterday with a dremel. I don't have my tool grinder up online yet. Nor do I have the accessories as well to do it. So I tried with a dremel, sized the stone for the groove.

I imagine that it's extremely tough to get that indexing finger to engage in the exact same spot every time.

The clue is it's a roughing end mill, as long as it cuts it is doing its job. So don't dismiss your failure, it doesn't need to be pretty, just cut.

Hey Steve, bought myself a mini cool recently, got me wondering what sort of coolant do you use with your mini cool? Thanks Glenn
I use Koolmist coolant in mine. I believe you can use any safe water based coolant

@@SteveSummers I have similar horizontal mill - do you think painting it with old paint on and filling in holes and uneven paint with Bondo would look nice or is just waste of time? Dissembling it all and cleaning mountains of paint is too scary for me.
hi bro
in the end mill of carbide the process is the same
i´m form mexico
You'll do a lot better with cutting oil in your K&T...I have three with oil in them.. All three had soluble before I got them.. Seized coolant pumps, garbage in the sump, etc. Oil is plug and play.. You go away for six months and when you get back to your machine you have oil not some form of dead decayed stuff in your sump.. Cheers! Mike in Louisiana
at 5:46 if you are NOT using the ear plugs PLEASE take them off, around the spinning mill cutter it is dangerous, can suck you in and take an eye or other part of your body perminently out of commission.
I wish you would have showed the end of the metal stock you cut with it. Also did you sharpen the end of the cutter? P.S your wife is Beautiful.
Ask ur dad if he heard..

In my My dreams I make those hog cuts
Your a machinist, build a automatic corn cutter.
He's already got one, he calls her Elizabeth. ☺
drop a neodymium magnet into the KT filter pocket.. that will catch all the metallic debris and keep it out of the bearings.. i put 4 or 5 stacked most rear ends and the oil does not change color even.. the magnets get covered but it keeps it out from between the bearing rollers.. i.imgur.com/9O0M4JN.jpg?1 like that..
well now you need to check out keith rucker's channel or him himself
I prefer voice over to extemporaneous speaking, especially on technical videos.
Excellent grind on that big hogging end-mill! (By the way, did you see High Speed Steve move across the screen whilst you were testing that end-mill? ;) )
That's a well sharpen metal corn.
