Tony, just wanted to drop by and say thanks. I'd consider myself a fairly experienced hobby machinist, but after watching this video on carbide tips, I went into the shop and raised my spindle speeds and cut depths considerably. Holy heck. I can't believe the results. Now running 3 x faster and taking cuts 4 x deeper. Instead of swarf, I'm now covered in 1" long chips. I'm now taking 40 thou at 1250 rpm. You Sir are a legend.

Your depth of cut should normally be a minimum the same as your nose radius, and a true bare minimum of 2/3 your nose radius. So if you were using a "08" nose (1/32") then 40 thousandths is good, and a typical minimum of .032" depth. Hopefully if you were only taking .010" cuts before you were using an 04 (1/64) nose, since the absolutely minimum of that is a 10 thou cut. Those are just the general rules for proper chipping and surface finish, but also require a proper feed rate and RPM top go with them. The maximum depth depends on the insert type, how much HP the machine has, and how rigid the machine is. A CNMG type has the largest depth of cut (.667 * length of insert edge), next is a TNMG and DNMG (.5 * edge length). WNMG is usually the smallest maximum depth of cut insert type (.25 * length to the middle point of the edge), but the tradeoff is it can be used for both turning and facing and has 6 cutting sides per insert.

1 Carbon Steels Carbon steels have been used since the 1880s for cutting tools. However carbon steels start to soften at a temperature of about 180oC. This limitation means that such tools are rarely used for metal cutting operations. Plain carbon steel tools, containing about 0.9% carbon and about 1% manganese, hardened to about 62 Rc, are widely used for woodworking and they can be used in a router to machine aluminium sheet up to about 3mm thick. 2 High Speed Steel (HSS) HSS tools are so named because they were developed to cut at higher speeds. Developed around 1900 HSS are the most highly alloyed tool steels. The tungsten (T series) were developed first and typically contain 12 - 18% tungsten, plus about 4% chromium and 1 - 5% vanadium. Most grades contain about 0.5% molybdenum and most grades contain 4 - 12% cobalt. It was soon discovered that molybdenum (smaller proportions)could be substituted for most of the tungsten resulting in a more economical formulation which had better abrasion resistance than the T series and undergoes less distortion during heat treatment. Consequently about 95% of all HSS tools are made from M series grades. These contain 5 - 10% molybdenum, 1.5 - 10% tungsten, 1 - 4% vanadium, 4% Chromium and many grades contain 5 - 10% cobalt. HSS tools are tough and suitable for interrupted cutting and are used to manufacture tools of complex shape such as drills, reamers, taps, dies and gear cutters. Tools may also be coated to improve wear resistance. HSS accounts for the largest tonnage of tool materials currently used. Typical cutting speeds: 10 - 60 m/min. 3 Cast Cobalt Alloys Introduced in early 1900s these alloys have compositions of about 40 - 55% cobalt, 30% chromium and 10 - 20% tungsten and are not heat treatable. Maximum hardness values of 55 - 64 Rc. They have good wear resistance but are not as tough as HSS but can be used at somewhat higher speeds than HSS. Now only in limited use. 4 Carbides Also known as cemented carbides or sintered carbides were introduced in the 1930s and have high hardness over a wide range of temperatures, high thermal conductivity, high Young's modulus making them effective tool and die materials for a range of applications. The two groups used for machining are tungsten carbide and titanium carbide, both types may be coated or uncoated. Tungsten carbide particles (1 to 5 micro-m) are are bonded together in a cobalt matrix using powder metallurgy. The powder is pressed and sintered to the required insert shape. titanium and niobium carbides may also be included to impart special properties. A wide range of grades are available for different applications. Sintered carbide tips are the dominant type of material used in metal cutting. The proportion of cobalt (the usual matrix material) present has a significant effect on the properties of carbide tools. 3 - 6% matrix of cobalt gives greater hardness while 6 - 15% matrix of cobalt gives a greater toughness while decreasing the hardness, wear resistance and strength. Tungsten carbide tools are commonly used for machining steels, cast irons and abrasive non-ferrous materials. Titanium carbide has a higher wear resistance than tungsten but is not as tough. With a nickel-molybdenum alloy as the matrix, TiC is suitable for machining at higher speeds than those which can be used for tungsten carbide. Typical cutting speeds are: 30 - 150 m/min or 100 - 250 when coated. 5 Coatings Coatings are frequently applied to carbide tool tips to improve tool life or to enable higher cutting speeds. Coated tips typically have lives 10 times greater than uncoated tips. Common coating materials include titanium nitride, titanium carbide and aluminium oxide, usually 2 - 15 micro-m thick. Often several different layers may be applied, one on top of another, depending upon the intended application of the tip. The techniques used for applying coatings include chemical vapour deposition (CVD) plasma assisted CVD and physical vapour deposition (PVD). Diamond coatings are also in use and being further developed. 6 Cermets Developed in the 1960s, these typically contain 70% aluminium oxide and 30% titanium carbide. Some formulation contain molybdenum carbide, niobium carbide and tantalum carbide. Their performance is between those of carbides and ceramics and coatings seem to offer few benefits. Typical cutting speeds: 150 - 350 m/min. 7 Ceramics - Alumina Introduced in the early 1950s, two classes are used for cutting tools: fine grained high purity aluminium oxide (Al2O3) and silicon nitride (Si3N4) are pressed into insert tip shapes and sintered at high temperatures. Additions of titanium carbide and zirconium oxide (ZrO2) may be made to improve properties. But while ZrO2 improves the fracture toughness, it reduces the hardness and thermal conductivity. Silicon carbide (SiC) whiskers may be added to give better toughness and improved thermal shock resistance. The tips have high abrasion resistance and hot hardness and their superior chemical stability compared to HSS and carbides means they are less likely to adhere to the metals during cutting and consequently have a lower tendency to form a built up edge. Their main weakness is low toughness and negative rake angles are often used to avoid chipping due to their low tensile strengths. Stiff machine tools and work set ups should be used when machining with ceramic tips as otherwise vibration is likely to lead to premature failure of the tip. Typical cutting speeds: 150 - 650 m/min. Silicon Nitride In the 1970s a tool material based on silicon nitride was developed, these may also contain aluminium oxide, yttrium oxide and titanium carbide. SiN has an affinity for iron and is not suitable for machining steels. A specific type is 'Sialon', containing the elements: silicon, aluminium, oxygen and nitrogen. This has higher thermal shock resistance than silicon nitride and is recommended for machining cast irons and nickel based superalloys at intermediate cutting speeds. 8 Cubic Boron Nitride (cBN) Introduced in the early 1960s, this is the second hardest material available after diamond. cBN tools may be used either in the form of small solid tips or or as a 0.5 to 1 mm thick layer of of polycrystalline boron nitride sintered onto a carbide substrate under pressure. In the latter case the carbide provides shock resistance and the cBN layer provides very high wear resistance and cutting edge strength. Cubic boron nitride is the standard choice for machining alloy and tool steels with a hardness of 50 Rc or higher. Typical cutting speeds: 30 - 310 m/min. 9 Diamond The hardest known substance is diamond. Although single crystal diamond has been used as a tool, they are brittle and need to be mounted at the correct crystal orientation to obtain optimal tool life. Single crystal diamond tools have been mainly replaced by polycrystalline diamond (PCD). This consists of very small synthetic crystals fused by a high temperature high pressure process to a thickness of between 0.5 and 1mm and bonded to a carbide substrate. The result is similar to cBN tools. The random orientation of the diamond crystals prevents the propagation of cracks, improving toughness. Because of its reactivity, PCD is not suitable for machining plain carbon steels or nickel, titanium and cobalt based alloys. PCD is most suited to light uninterrupted finishing cuts at almost any speed and is mainly used for very high speed machining of aluminium - silicon alloys, composites and other non - metallic materials. Typical cutting speeds: 200 - 2000 m/min. 10 Other Materials To improve the toughness of tools, developments are being carried out with whisker reinforcement, such as silicon nitride reinforced with silicon carbide whiskers.

I used to sell carbide tooling. Worked for Seco Carbide. The number one tip for carbide mill cutting (apart from not feeding too slow) is to not use an external water source. Rather cut dry. Water is only beneficial if you have a fancy through-coolant system. An intermittent source of water causes carbide tips to crack and wear quicker. Another tool we sold was a high feed milling cutter. That thing was amazing. It could not take deep cuts by design, but the speed you ran it at meant the job went ridiculously fast. But you need a CNC mill and plenty of RPMs. One thing I've learnt from that cutter was the methodology behind milling and turning. I was taught as toolmaker to cut along the X or Y axis (on a mill) for heavy material removal. For heavy material removal, you can't beat dropping a cutter down the Z axis. It takes a lot of load off of your machine's X and Y and it removes material super quick. Generally keeps the job cooler too. It's the same for lathe work. When you have plenty of material to remove, drop the tool into the job on the X axis. You'll need an S-type or T-type insert with the correct holder. Finally, for parting on a lathe, you can't beat carbide.

The quality of your videos is just amazing Tony, your channel really is one of the gems of yt!

Tony fantastic job again! I did want to add that the coating in the inserts I sent you is PVD rather than the TICN coating you have been running . The coating as amazing , it is what provides the cutting surface. I like to think of it as a layer of magic. This provides a very sharp cutting edge and why your part was cool when you where done. I have seen a significant drop in power needed to use the newer PVD tooling. Again love what you are doing for the Hobby people, keep up the great work!

I have found that Seco has worked the best for us here. The speeds are amazing for the new carbide. The new tools will allow for 1700 - 1900 FPM . We can't run that fast on most of the parts we make but in testing DNMG tooling with a nice sharp tip and a low feed chip breaker have allowed us to make some amazing parts on small lathes. We where doing Tops at cabin Fever in PA. The people asked me how I polished them, I had to cut one to show we where not doing anything. I don't know the formula of the coating but I can tell you that it works and it is scale able down to a 500W spindle.

Fabulous presentation - especially for those like myself still harbouring a myriad of questions - many of which you answered. A serious expression of my sincere gratitude is hence forth given!

Another great video Tony! One thing that keeps coming up on hobby forums for people with smaller lathes is they always say they can not remove much material on them because they are not heavy enough and/or don't have enough horse power. I have an old Craftsman 12" lathe, and find that for the most part, if you use it like it was designed, using a lantern tool holder, HSS and the proper high positive rake, you can peel off much larger amounts than using a quick change toolpost and insert tooling. Now I will say I also do not use the lantern very often, and use insert tooling, but because of the higher speeds and feeds required, as you pointed out, I typically use HSS inserts from Arthur R. Warner in my holders. They cut much better at lower speeds, and you can keep them sharp with honing. Keep up the great work, love watching and learning!

I totally love carbide endmills. Carbide tools on the mill don't bend as much and also last long, even in the home shop.... that is unless you use carbide on a lathe like mine, the one that stops as the belt slips, welding the fractured carbide bits to the work. Oh, the joys.

I have a very old South Bend lathe with a flat belt drive. I replaced the old leather belt with a more modern stronger and tougher one but it slipped more, making it harder (read slower) to get any work done. What I eventually did was buy some 3M Scotch rubber electrical tape (3/4" wide) and I wrapped two layers on each pulley on the drive and the lathe head...so six surfaces in all and PRESTO!!I can now take bigger cuts and the lathe is quieter, no click click as the belt goes around. I have to change the rubber about once a year....the tape is not crazy expensive and the roll lasts me a few years. Try it, it works great. NOTE: I do not mean the typical black vinyl electrical tape.....you have to get the rubber stuff....it sticks to itself but is not "sticky" per se.

TOT: you are a brave soul to tackle carbide tooling as a topic, there are sooooooooooooooooooooo many variables, not the least of which is many home shop lathes are of a vintage and or style not really meant to take advantage of the benefits of carbide which in turn (ha, ha?) means increasing those variables at least several exponential levels.

Hi Tony, this is Old Bob. excellent and very useful presentation. camera work equally great with machining. I like carbide inserts and the fact that their edge finishing has a bit more tangential aproach to the work as HSS has. Sometimes I feel that as HSS ground it's only scraping off material instead of "peeling" it off. Being from old school I used to the tangent type of "grinding tools". It could also be mentioned that carbide tools cannot take vibrations, a specially on cheap mini mills.

Tony, like most of the comments affirm I too, tend to stop what ever I'm doing when a new video hits (usually at work), develop an emergency blader issue, and bail out of sight for twenty or so minutes. I personally enjoy your longer videos. Keep it up man.. tho old, crotchety kats like me that are out there need you to remind us why we chose this method of meditation I the first place!!

This is quickly becoming my favorite channel! Awesome work on the videos

Slightly off topic but I'd like to mention that the Chinese haven't yet found a way to mix the lead/butter mixture into carbide endmills like they have with their pot metal... I mean "steel"

04-03-02, or more commonly 432, is hands down the most popular (ie easiest and cheapest to find used) size, so that 848 is just silly big. Hobbyists should be in the 332 size area really, especially if buying new (20% costs savings over 432). The W and S are popular, but the C shape rules, since the 80 degree diamond gives you 4 cutting corners. Don't bother buying new anything not rocking that N for zero relief, since you double your cutting surfaces and besides your tool holder gets you the relief. Buying used, try sticking to the 432 if costs are a big issue. Or just go silly with the variety if the prices are good, and you're just curious.

There will never be a time when this channel doesn't put a smile on my face. Plus it's useful and inspired me to learn machining

Great review of the first 5 weeks of my welding 103 class, thank you!

So, where do you get your nails done? I have subscribed in anticipation.

Having just ordered my first set of carbide-insert cutting tools (the cheap ones off Ebay) for my new mini-lathe, this video was exactly what I needed to understand what I'm getting into. When I worked at a machine shop back in the 80's, we had HSS and brazed carbide - no inserts for us. As a hobbyist who doesn't have a grinder yet, the inserts are a great option to have.

Grinding hss is nutritious for toolroom penny. Once you get to see the result of eyeballing radii yo kinda get to feel what your machine is able to do. Dont avoid learning the craft, because it will come back to bite you.

Im not into this thing, i don't do nothing with steel, carbide or any of it. But somehow i enjoy and love your videos. You making stuff and talking about things is calming and relieves stress for me. Thank you

Fantastic video, I am envious of your machining + video making. I will have to rewatch a couple of times to pick up all the info - I am overstimmed right now. Thank you.

THANK YOU for the explanation. Got a new to me old lathe with these kinds of tools and I had no idea where to start. I've run my Rockwell 14" 3hp since I was 8 (26years) with nearly all of the other tooling, now I am getting ready to turn my American Pacemaker 16"x54" on for the first time and have a better understanding of these 'weird' tools.

Carbide is a sintered product. Manufactured using high temperatures and pressures. It is generally unaffected by exposure to high temperatures. And can with stand high pressures as long as it isn't applied as a shock.

Or as long as the shock doesn't dynamically exceed it's integrity.

Very informative! Thanks, Old Tony :D Why is it that carbide likes to be run fast?

@robmckennie4203

7 жыл бұрын

I believe it's because it's not as sharp as hss, and therefore needs a higher surface speed to give a good finish. As for why higher surface speed gives a better surface finish, i have no idea, but i'd like to know if someone else does.

@DrKnow65

7 жыл бұрын

It burnishes the surface (melts it a bit) because the carbide is not super sharp at the cutting edge. HSS shears the metal away so the sharper it gets the less tearing and the better the finish.

It doesn't require high speeds. It simply has the capability to run much faster than hss. The higher cutting speeds are to take advantage of its high temperature hardness

Oh I was just about to drive over to my shop an now im watching a video on carbide. Thanks Tony

"Turning raw materials into scrap metal".. I don't own a lathe and I'm liking this video. Such a good teacher. Thank you in 2020,Tony.

BTW, don't you think for one second that I can't compete with you on broken endmill prroduction. I 'm very impressive.

I go to yard sales and markets and buy old and broken files. Its the cheapest way to get tool steel for making lathe tools

@k4kfh

4 жыл бұрын

Yes, that works to get cheap tool steel, but this is not high speed steel. It will anneal and soften at a relatively low temperature. Also, lots of files are case hardened, so you may get an unevenly hardened tool unless you anneal/reharden the tool after you've ground it.

Tony, if you had been a school teacher, I may have gone on to get a doctorate or two. Very informative and as usual, well presented. Your time, much appreciated.

Finally a decent video on this subject. Thank you. Now I know HSS is still the right thing for me at this time. Your channel rocks!

I'd say it is actually pretty apt. When you're talking about something as in-depth as machining, 30 minutes spent talking about something as general as carbide tools, that is a pretty brief chat. I bet Tony, or any machinist, could spend hours talking more at-length about even just one type of carbide tool.

@zombieresponder

I'm a machinist by profession. I didn't watch the entire video. 30 minutes IS a "brief chat" on the subject of carbide cutting tools. If you don't have 30 minutes to spend learning about it, then you probably don't need to be anywhere near a machine tool either.

Lol so that's how he gets his moving shots

It's hard not to pick up a lot of great insights here, thanks for sharing and making these great videos.

problem I got with these chip break tests people keep doing is that the diameter keeps changing but speed and depth of cut remains the same. it is the material removal rate that dictates the chips. all insert tooling guys include that spec on their inserts, then you just calculate proper feed and speed for the diameter of the cut you are doing, using maths somehow.

pontusieg, what you're referring to is surface speed. In order to maintain a specific surface speed, as the diameter decreases, the rpm needs to increase. Depending on the grade of insert and the material to be machined, I use the formula: 315 (pi) × cutting speed in m/min ÷ diameter in mm= rpm. So... 315×180=56700, then 56700÷200=283.5 rpm. 180m/min being a conservative, continuous cutting speed in 4140 steels. its a bit late, but i hope this helps.

I almost spit out my chocolate chip cookie while watching

Im in my vocational training as a Mechatronic right now here in germany and before it started, and i watched your videos like 2 years bevore it started. Now im just sitting at home watching those Videos in my freetime, realising how much i love metalwork 😁💕😊😊

I have a 6" Craftsman Atlas lathe on my sailboat. Getting geared up to cruise the world and came here with tons of questions about what type cutting tools I should be taking with me. All of my questions were just answered! Thanks!!!

Nice video as always! One thing though. My (old) teacher would completely shoot you for picking up chips/coils by hand. Aluminum isn't sharp enough to cut you (well....), but next time it's stainless steel or so, and just out of habit it pick it up with your bare hands again. Long story short, my teacher couldn't bend one of his fingers anymore.

It depends a lot on how tough the skin on your hands is. If you work every day in a shop you can pic the stuff up no trouble. Go on holliday and come back 4 weeks later and youll slice yourself to the bone.

As usual, an excellently detailed and informative video. Many thanks Tony.

Not owning a lathe, nor a milling machine, I had no practical reason to watch this. However, it caught my attention and it was fascinating. Really nice style, Tony, and I learned a lot. Thanks.

A very interesting video personally I enjoy the mathematics of HSS but when I feel lazy I use carbide.
