Parting on the Lathe

Parting is one of the most misunderstood machining operations on the lathe. This video covers how to properly grind the tool, how to set the tool so it is rigid and properly aligned, and lubrication. Following these basic guidelines can greatly reduce the amount of heartburn associated with the parting operation.

[@fsj197811]

Who knew it was that simple to sharpen a parting tool? WAY easier than shaping a square piece of tool steel. Thanks for sharing. And yes, I'm still learning. 🙂

[@ColinMill1]

One handy tip I was taught at Tech. college about 50 years ago was to set the tool height using a small diameter ground rod held in the chuck and then trap a 6 inch steel rule between the tool and the rod. If the tool isn't spot on for height the rule won't be vertical (viewed from the tailstock end) and from the way it's leaning it's easy to see whether it's high or low.

[@johnpattinson1961]

Looked at lots of these instructions over the years and this is the best and complete parting video I've seen

[@oxtoolco]

Hi Tom, Very nice video. I'm sure there are a bunch of folks that will breathe easier and be more confident parting in the lathe. All the best, Tom

[@TomsTechniques]

Thanks Tom. I don't know if you ever breathe easy while parting, but hopefully this will increase the confidence level a bit. Tom

[@keldsor]

Nice instructive video - as always -thx ! The grinding ... I like to grind mine with a little "twist" so the parted off peace loosens before the center is reached on the left part - that's even better, I think, if there is a hole bored - no burr is left on the parted off peace ... on the other hand ... maybe I'm wrong ?

[@TomsTechniques]

Keld Sørensen A hole through the center always helps, but be careful with the angled blade. That will cause the blade to creep sideways and bind. You can get away with it on small parts with little overhang, but larger parts will be a problem. Tom

[@keldsor]

Tom's Techniques Yeah, ONLY small part with holes, you'r just right.

[@Sketch1994]

@@TomsTechniques Used to part off tiny brass parts at 1600rpm with the auto feed engaged. Parting tool always set on center, parallel to the travel with the correct inserts for the application. Even though it worked flawlessly again and again I was always holding my breath for this part...

Hey Tom, Thank You Sir!! This video is going on 6 years old and its just as relevant today as it was the day you made it. NO distracting music! Thank you for you that! You spoke in a clear voice that even my deaf ears could understand perfectly. You didn't use a lot of Big Fancy $10 words, you spelled everything out in plain simple english that even a nimrod such as myself could easily follow. Looking for more of your video's as soon as I post my reply. Again, Thank You Sir!!! JohnArcher

One very well done video. And the process was explained very well also. A true professional

[@rob12449]

Excellent tutorial! I acquired my first lathe, a dirty old sheldon 11, and ordered a hss parting tool. I realized this is a controversial topic but now I'm sure doing it the right way should succeed!

[@woodbrassandglass]

Thank you for your info! I have been trying parting for 10 years and it never worked well. I did exactly what you showed, twice and the cut parts came out PERFECT!! Thank you so much! This video will now help me so much in all the years to come! Thank you!!

[@TomsTechniques]

That's good to hear. The set-up for parting is pretty critical and there is a lot of things that need to be right for it to be successful. Glad it worked out for you. Tom

[@ingDemurtas]

I saw this video several years ago, had problems parting, came back to watch this video -> found the solution to my problem

[@Mike-kd1ok]

I have the same exact Hardinge lathe. It has seriously prejudiced me against other engine lathes... so awesome to see another guy using that awesome machine.

[@TomsTechniques]

I would have to agree, although my opinion is somewhat prejudiced. :)

[@AddictedtoProjects]

Awesome video Tom. Thank you for making it. I spent a good 2 hours today fighting with 2 different HSS parting tools, because as it turns out, I had them slightly below centre. I thought that's where they needed to be located, until I saw your video! =) Confidence has been rebuilt. Thank you Tom!

[@orwad7916]

My one-to-go video when it comes to parting. Clarifies and pretty much sorts out the frustration in the most comforting way possible.

[@TomsTechniques]

Parting can still be scary, but less so with a bit of knowledge.

[@tommy-katana3615]

Thank you so much for this video! parting has been the bain of my life and was easily fixed thanks to this quick lesson I was one of those individuals grinding that hook on the end After changing the tip profile it worked perfect! Thanks Again!!!

[@rayrenzi4860]

I damaged 4 parting tool tips yesterday afternoon..... I wish I had come across this vid earlier! I see all my mistakes now. Great vid. Thanks.

[@peterclancy3653]

Good on you mate. Just solved my problems. I have a round bed Drummond lathe and I think the ridgidity and the speed are my main issues. Thanks

[@mguuu813]

Ive never had much success parting, this video is great, clear and precise, I will try again now ive watched this, many thanks .

[@EVguru]

Very nicely presented! When I had a Boxford, I milled a flat area at the back of the cross-slide and made a rear toolpost. Combined with flood coolant I could part off with confidence. When I got my Harrison L5, I was for a while parting off under power with an HSS blade holder in a Dickson QC. Then I went through a whole load of shattered blades and ruined parts and almost gave up parting off. Now I have a Dorrian BXA toolpost and use an inserted blade holder mounted upside down so the swarf falls out of the cut. It also allows you to easily see the finish in cut, so you can spot any problems, a chipped edge, or buildup etc. and do something about it before a disaster. I keep my topslide gibs very tight for rigidity which helps a lot. I can always slack them off if I have to get a smooth finish on a short taper.

[@TomsTechniques]

Good tips Paul! Thanks for watching. Tom

[@marcmckenzie5110]

Tom, this was a great video. I've been planning my shop and machines for a very long time, read and watched a bunch. Tonight with my wife watching, I did the first lathe work of my life (and enjoyed it so immensely it must not be legal!). My huge project was to take some 7/8" aluminum round stock, cut off a chunk, true it out, face it, cut through the dull finish, knurl it, chamfer the edge and then part it out. Everything went like clockwork until parting it out - then I realized I have not been paying enough attention to these details! In the end, I parted it with a vice and a hacksaw, and my wife fell asleep before I could drill and press an existing cap-head screw to turn it into an easy access knob to the gear housing. So 80% there. But along the way, I noticed a pile of things I need to address in my process and tool prep. You have a new subscriber! Grazie!!

[@TomsTechniques]

It's always great to hear from an enthusiastic novice. Parting is one of the most difficult machining processes, so don't get discouraged. Once you learn the ins and outs of your particular lathe, it will get easier. Have fun! Tom

[@gb_engineer]

thanks Tom, i had no luck before i watched your video, but now have managed to part off without breakage! very pleased

[@TheEmporiumOutdoors]

Great video, I'm really enjoying the beginners guides, learning lots. One thing I do in addition is lock the carriage once i'm ready to part off. Really helps on my lathe with rigidity.

[@TomsTechniques]

That's a good tip. Thanks for sharing it. Tom

[@RyanWeishalla]

Nice, simple to understand video on parting. One of the things I've learned as a beginner/hobby was also understanding that similar to limiting the overhang of the tool is the overhang of the work piece being parted off, especially on smaller pieces.

[@TomsTechniques]

Yes, minimum overhang should be considered for everything from the tool to the work, even the compound.

[@louisnoel3170]

You are awesome ! Went to School along time ago for auto mechanics and still do that . Always wanted to do machine work too . Finally got A mill , Lathe and other metal tools so these vids are great !

[@Captain_Nemo-y7q]

When I was an apprentice scientific instrument maker, I was taught to never stand in front of a grinding wheel when it was running up to speed, because as it was running up it would pass through resonance frequencies related to any slight imbalance there might be in the wheel, and that is when the wheel could shatter. A grinding wheel shattering in your face could be horribly injurious and possibly fatal. I have enormous respect for your skills, so it was something of a surprise to me that you stood in front of the wheel when starting it.

[@TomsTechniques]

That is a good rule to follow, but it is more applicable to a newly mounted wheel on a surface grinder, than one that has been in service on a bench grinder. Surface grinder wheels are much more friable than those used on a bench grinder and, since they are often removed and replaced, are much more susceptible to damage. It never hurts to stand to the side of any wheel, but the chances of a wheel failing on a regularly used bench grinder are slim to none.

[@paulgreenlee190]

[@Stridercrazy]

Thank you very much for this, just tried your method and it worked flawlessly.

[@TomsTechniques]

Excellent. Thanks for watching! Tom

[@NOSLEEPATALL]

Pretty much reminded me of what I should have done in the first place as I have my compound rest hanging out about 3”. Pulled it back in over the cross slide and BOOM cut 4 pieces without issue as compared to the first one that popped the tool out of the holder.

[@kgee2111]

Thanks Tom! Half the time, I’ve been staring with the parting tool and finishing with a hack saw because my tool always grabbed and broke etc. I’ll try it again your way!

[@TomsTechniques]

Nothing wrong with finishing up with a saw. I've bandsawed larger pieces myself after reaching as far as I could with the parting tool.

[@6milesup]

Thanks Tom! I purchased a 10-22 Precicision Matthews lathe a little while ago and have been trying to figure out this parting operation. Your tips were very useful. I need less speed, more oil and to make sure the cutter is straight. Scared the crap out of myself a couple times when the cutter bound up. Yikes!

[@TomsTechniques]

+6milesup Yup, that really gets your attention. Glad the video helped. Tom

[@RJGMWR]

I have used the squaring up against the chuck method and never thought to use the indicator to square it up,makes perfect sense.

[@TomsTechniques]

The indicator takes a bit longer, but it ensures that the tool is dead square, which is the most important part of the set-up. Tom

[@ronslaughterandalice1018]

My funniest experience parting was in the Navy. On my ship there were life jacket cabinets all down the side of the decks with brass knurled knobs that held them closed. The guys would take those knobs and throw them at sea gulls so I was continuously making new ones ( several buckets full per week.)

Thanks Tom, I've just bought a lathe & that was awesome

[@LarsBerntzon]

Thanks Tom, nice video. On my china lathe i learned that when i move the compund to almost parallel to the cross slide and move the compound far back I get much better regidity.

[@TomsTechniques]

Lars, Whatever it takes to reduce overhang will help. It's great that you experiment with your machine because they are all different. Tom

Good advice, I would just add one more thought. On my older South Bend 9 I find it helps alot if I snug up the gibs to ensure a tight setup with NO play. Usually just tighten up one screw on the cross slide and lock the carriage. Parting has always been a white knuckle adventure in my shop !!

[@TomsTechniques]

Absolutely. I've done plenty of parting on South Bend lathes. Anything you can do to increase rigidity will help. Thanks for watching. Tom

[@hakimmic]

Hi Tom, Thank you for another helpful video. The new tool post made a big difference over the lantern type. George

[@TomsTechniques]

Thanks for watching George. You got a new tool post already? Tom

[@PaulAndMuttley]

Another good video on a sometimes tricky subject. I had a small cheap parting tool made for a mini-lathe that had a thin T-blade as you show, but it did not hold the blade very well. It worked OK on Delrin but when I tried it on steel it seemed to grab and jump as I tried to keep a steady feed. What was actually happening was the blade was being pushed back into the holder, and as I neared the center the holder hit the work and snapped. I also have a cheap carbide tipped tool from HF that I touched up with a diamond file and it worked OK on mild steel, but it did not seem to want to work on a galvanized steel pipe fitting (probably more like cast iron). But it's also tricky to part pipe, as the bore may not be exactly concentric and the tool will catch where it cuts through. I used a hacksaw and then faced it on the lathe. Thanks for the tips. BTW, I think it is better to err on having the tool below center, as the rotation will push the tool tip down and away from the work. If it's above, the downward motion will push the tip into the work and grab or chatter. YMMV..

[@TomsTechniques]

For best results, the tool tip should on dead center, NEVER above or below. If it's above center, the tool will drag under the cutting edge and if it's below, it will pull in as you near then center of the part.

[@escargod]

What causes chatter/vibration? I don't see it when I use the power feed!

[@Ujeb08]

Hi Tom, this was well presented. Alot of my machinist buddies are afraid of parting tools. But as you said - if you're set up right, there shouldn't be a problem. I just recently purchased an Iscar blade and block type parting tool that uses carbide inserts. I have parted off 4" diameter 6061 aluminum using a 5/32" wide blade many times with no problems. Of course if there's enough material I would normally tell my students to use the cutoff saw. But they sometimes get themselves boxed into a corner and I part the bigger stuff off for them so they don't break my expensive tool. Thanks.

[@TomsTechniques]

Ujeb08 Thanks. On larger parts, I'll sometimes part them off part way through and finish up with the saw. That gives you a guide for the saw and saves a bit of time. Tom

[@PickingDude]

Awesome. Thanks for another great video. And yes it actually was a big mystery until now as it's one thing that I have and I haven't bothered using it because I didn't know anything about it. Looks pretty easy now.

[@TomsTechniques]

Don't get over confident. Parting is one of those operations that will jump up and bite you when least expected. Tom

[@PickingDude]

Tom's Techniques Oh great. LOL. I'll be careful when I try it and make sure the safety glasses are on. Thanks for the warning.

[@douglasthompson2740]

Hello Tom, Check, check, check, and check. Do all those things on my 12x36 Grizzly G4000G. I have used 'T' blades, beveled blades, carbide inserts of all kinds on my QCTP. Dead center and within a molecule of square. Been playing with it for more than ten years of home shopping and eight out of ten times it seems to go well almost always when I am parting a tube or hole in the center workpiece. When it comes to parting of solid stock the tool(s) seems to do very well until they get to the small diameter and then the tool pressure increases dramatically and comes to a stall. If I power feed same thing. I have shattered carbide, destroyed blade holders in parting tools, broken grooving bits and holders, pushed HSS blades back even with the wedge holder clamped very very securely. I use lots (steady drip) of cutting fluid to no avail. The last time this happened I was parting a two and a half inch solid aluminum rod!!! Broke the insert and tool holder as well as rotated the QCTP (yes it was cranked down). The only thing I haven't tried with my track record I am reluctant to boost rpm above the six hundred mark as things happen pretty quickly at those rpms. I have tried everything from 600 rpm on down though. Any thoughts on why the tool pressure elevates so much as it approaches center? I am totally stumped. I get success enough to keep trying but these crashes are making me gun shy for sure. I have sharpened and honed both the HSS and the carbide (honed). Present practice has me grooving the piece and finishing on the bandsaw. I have watched countless videos and tutorials without seeing a solution. Needless to say this is a very good subject and thanks for the video. Take care. Doug

[@TomsTechniques]

Two things will cause the resistance to increase as the tool approaches center, either the tool is set too high, or there is increased friction on the sides of the tool. You mention using cutting fluid. I prefer a good old fashioned sulfur based cutting oil for parting. That may help with the latter. Tom

[@n9viw]

4:20 "If you're using a lantern-type toolpost... good luck. They're not known for their rigidity, and your chances of successfully parting are GREATLY REDUCED using a lantern-type or rocker-type toolpost." Truer words were never spoken! Last weekend I needed to make a gib screw for my '42 SB 10R, and used a 1-1/4x4" bolt for stock. I decided to part the head off... there's an hour I'll never get back. I should have used a hacksaw, I'd have been done sooner! 😂 Next payday: a parting tool holder for my turret toolpost...

[@Just1GuyMetalworks]

Thanks for the vids Tom. Your tool sharpening video was super helpful. I have a lantern style tool post at the moment and have yet to successfully part steel. I have however successfully jammed my lathe lol.

[@TomsTechniques]

Lantern tool posts lack the rigidity necessary for reliable parting. Plus, they tip the tool back, increasing the chance that the tool will grab the work. Glad the video helped.

Tom - nice video and it is great for someone who is well equipped like yourself. I suspect for the guy who has your setup doesn't need too much assistance for this basic function. I have (like a lot of guys who are having trouble) have the lantern style. We need help with the best technique for this style. Granted we should probably bite the bullet and buy a new holder but the lantern style has been used for a century. There has to be an optimum way. Your video is sort of like teaching someone to cut a board with a Powermatic table saw when all he has is a hand saw. Norm Abrams loves to show off his tools but never shows the average guy how to do it with a hand tool. Please consider another video for the 100 year old lathe guys. Thanks for considering..

[@TomsTechniques]

Mark, The tips that I demonstrate in this video apply to any lathe (even the 100 year old ones) and any tool holder. There is no magic bullet for less rigid machines, You just need to make the setup as square as possible, use LOTS of cutting oil and use one of the T shaped blades like I demonstrated in the video because they are much less apt to bind up in the groove.

[@jiml9944]

Those with light duty lathes like the Craftsman 12" might be helped by these: Worth a try. 1.Use the tail center. A dead one works better for me than a live one. More rigid. Yes, you cannot cut off but you can get close. 2. Run the lathe in back gear, but not at a ridiculously low speed. Evidently removing the sloppy connection between the big spindle pulley and the adjacent gear helps. I note the spindle is also driven at its opposite end. Why this helps me is unknown to me. Note: Thick sticky oil also keeps the chips together, not a good thing. To each his own. Jim in Clarkston Mich. An' old timer.'

Thanks you saved my time

[@georgefarmer3696]

I use a mini lathe and this what has given me the most problems. One of the things I found was that i needed to re- adjust the cross slide as there was some up\down movement. that led to re-setting all the gibs as well. Only just done this not had a chance to see if this improves my cutting off. One thing you didn't mention was to lock the carriage to the bed.

[@airgunningyup]

part off close to the chuck , and use the variable speed if you have it , so your rpms are increased as you approach the center thus keeping the fpm the same

[@airgunningyup]

also, on the mini lathes its tough to have a smooth feeding compound and a rigid tool rest all in one.. I always use to overtighten the center gib screw just a 1/4 turn for parting , then back it out after for normal use.

[@steveclark..]

Great tip on the gib screw, these mini lathes are just not rigid enough out of the box, I've snapped a parting off tool, it's not a T profile one though, will look for those next time.

[@airgunningyup]

Steve Clark yes, when parting i have to say my bigger machine , although not huge ( grizzly g4000) is a lot more forgiving .. I can screw up and not always snap a blade or crash the work.. i still use the gib screw trick though above 1 inch diameter aluminum

[@canuckfixit7722]

Great job. Made it look so easy. Couple of questions: 1 - What is "lantern-style" tool holder and 2 - Did you cut machine grade steel? How about plain carbon steel? Just as easy?

[@TomsTechniques]

A lantern style tool holder can be found on light lathes, such as the Atlas and South Bend. It's basically a cylinder with a slot in it to accept right hand, left hand, and straight tool holders. As long as everything is set up properly, the steel type doesn't make much difference.

[@francislambert5189]

I will have to consider doing this type of cutting from now on. Thank you. Peace :)

[@Iceman-kr6df]

Another note about chip breakers and a reason why I don’t like them: I find they increase the tendency for the tool to get sucked in, and in deep grooves they can, in my experience, cause chip evacuation problems. The chips end up curling up on top of the tool like green onions, then binding up instead of getting out of the way like the would on a flat topped tool

[@Trenz0]

I'm just starting to work on a lathe and I noticed that as well. It almost feels like the angle causes the tool to want to "slide down the ramp" it makes but that could just be my inexperience and inconsistent feed rate

[@Iceman-kr6df]

@@Trenz0 if you’ve got chip breakers try grinding them less aggressively. I’ve found that longer/shallower chip breakers cause me fewer problems

Thanks once again, Tom. I like how you explain stuff, I learn a lot from you and I'm grateful for that. :) Looking forward for your next videos! :)

Thanks. I think I have one more to post on the basic lathe work and then I'm going to take break for a while and put together the next project tutorial, a micrometer carriage stop for the lathe. I hope to post the drawings for it on my website (tomstechniques.com) this evening. Tom
