Thanks for including the metric values as well. It's very helpful to me being a CNC operator in Norway. It's very helpful and provides me the extra knowledge that I need every day. I hope to see more of that in the future. Love your series on how to machine those extra hard alloys. Keep it up. Boom!
Excellent! It's more about understanding tooling feeds and speeds and tool pressure just like you said. I've been doing my best to teach this to people for ages. I did an .400 depth adaptive tool path with a 1/8 end mill in 17-4 and it worked perfectly. Everyone thought I was nuts.
Thumbs UP for metric. Please explain more about cutting pressures and vibrations and stuff, not only feeds and speeds, but why they are like this. Thanks
Basically by pressure he’s saying a smaller stepover/ radial depth of cut, keep a deep axial depth of cut and just walk the tool slowly. If you can image a bigger radial depth of cut, the machine is literally pushing the tool sideways into the material harder. So a smaller stepover is less “pressure”
Thanks Titan. Having both, Metric and Imperial units is very helpful. Good to see that you cover Tormach as well as Haas and DMG. I also appreciate that you develop and appreciate your team.
i know nothing about cnc machining , but i always watch your videos, such a strong team , titan you are the kind of boss i would like to work with, always positive & helping all
Absolutely awesome! Thank you Titan and company for promoting the industry (and hobby) learning! Please, if you could, work with your suppliers to get them to accommodate hobby machinists. It’s very difficult to purchase from the bigger companies as they often don’t offer an online web shop and don’t want to deal with small orders. I haven’t tried too many, but Helical is one example of a company I’d like to order from but find it’s almost impossible to place a small order.
Now we've got all the application videos on milling, and drilling difficult materials, it'd be good to see the same done for turning. OD turning, ID turning, face grooving, radial grooving, and parting. Maybe seeing some adaptive turning with button inserts, or prime turning if you use it?
I've always thought that the adaptive tool paths should have an option to increase feed rate or step over as the depth of cut is reduced to keep that chatter/vibration down as the tool pressure is reduced. Also, it would increase productivity.
I will say this, as a mechanical engineer, that tool pressure is a term that I have found to be misunderstood industry-wide. The definition of pressure is force per unit area, i.e. P=F/A. Think of a hydraulic cylinder being extended by a hydraulic pump exerting 3000 psi. A larger cylinder will exert greater force even though the PRESSURE is exactly the same. The reason is that the piston in the cylinder has a greater surface area, and therefore according to that equation rearranged for force, F=P*A, the force increases. In this same manner, when you use a smaller tool, it is not the tool pressure that is changing... it is the force exerted on it that is changing.
Back in the day of gear driven, low rpm, high torque machines it was far more important to watch your backlash. As the hydraulically driven, high rpm, low torque machines came about backlash was much les of a problem. its also a guide for using big multi carbide cutters. One keller shop I worked in burned up the gearboxes of 6 Kellers
Yoo titan I was working on haas machines in the past in some local small company and what we used was vacuum tables in the machines. So u dont need large clamps to hold it together and its way faster setup! Take look in to that!
@@TITANSofCNC I mean they are not really for titanium and hard materials, but for something soft like plastic or aluminium with no so much of a tolerance is turning out really good!
I can't find anyone who wants to learn. I've even provided employees laptops and given them my cell number to ask questions about running the software and none ask me anything. None even try to learn. It's incredible to me. I always wanted to learn design and cnc programming and taught myself.
i am so addicted to you're videos. well. about this tormach 770. wanted to buy one. but got bad feed back on play on the y axes that causes shatter and tool vibrating. can you please check play on the bed and quality before i spend money on some thing not worth while. thanks a lot for all the work you guys do and things that you guys teaches people.
I have A LOT of issues with my 770 in scenarios like this with high pitch chatter when cutting stainless. I can hear a little of that high pitch noise in the video around 5:55 in the video. Any suggestions on this?
Dear Titan cnc team, I’m a young individual in the trade looking to better myself as well as others. If you could consider making a video about inspiring and motivating your workforce I would greatly appreciate it. Derrick
For 7 years my 1100s have been machining stainless steel, hardened steel, 8620, 4140, tractor flywheels, Ampco 18, tool steel, HSS, doing farm/construction repair part machining, try machining a diesel engine wrist pin now that is hard.
Really interested in the Tormach machines, I can’t afford a big 3 phase machine plus I don’t have 3 phase at my home, but I could learn about machining with one of these
I know this is old, maybe someone can help me though. Where does Hastelloy fit in the hardness/toughness (I can never remember which is which) like is it harder/softer than Stainless steel? 4140? Mild steel?
I cut 6al4v in my 770 Series 3 constantly (I wish I had the more powerful spindle motor in your swanky new 770M). Is it absolutely ideal? Hell no. Does it make me money with nothing more than a 110v wall plug? Hell yes! Small cutters with steep angle of entry (1/8, 3/16, 1/4, max 5/16).
Do you re sharpen your Harvi III 's? If so, ones with chip breaker too? Send them back to Kennematel or where? Jusy got my shop to change tool paths and running the Harvi III. Love it! But need to know about resharpening please. Thank you
Will the zombie cutter cut high speed steel or tool steel as well as inkanal and moanal. I don’t have a cnc but thinking I could cut forming tools in the mill for my lathe?
That small cut reminded me of a whoops moment , i had a couple day ago . Feed around 1000 my hand was on override , but otherwise it was on rapid . 17.5mm drill low cutting speed . I was glad the part and the bit was still ok 😅
Hey titan when are you going to review the main milling machines makers and buy a new cnc bridgeport with heidenhain see if they still make them as good as they was back in the 30s
The new Bridgeports are made in Hardinge's operated plant in Taiwan. They are very nice machines. Owning older Bridgeport CNC's I can tell you that the new machines are more rigid and accurate. Hardinge controls all the QC and manufacturing in that plant. Only their high end lathes are still made in Elmira, NY.
Titan, you should get a new Hardinge H51 or a Conquest. I run 90's and early 2000's Hardinge lathes. Still Super Precision. If I was in your shoes, I would hook up with them! USA....BOOM!
Hey Titan. I know youre using a loot of Haas machines... do u ever have a problem with a holders in a revolver after 3-4 year old machines? Usually on the clamps that hold big tools?
Hi Guys, how about doing a more in depth film to help academy members specify their Tormach. What do we need as a minimum, what you would recommend for us to get from Tormach to help us follow through the academy program. You already have kits with Kennametal tools maybe its time for Tormach to produce a Titans Academy kit.
Come on guys, Lets get some more Tormach videos going! I have an 1100 in my garage I use on a product made out of 7075 T6. Show us how to push feeds and speeds with a 1.5HP machine that can only go 110IPS. Can I get a "Boom!"
@@TITANSofCNC Does it work to set the top height below the top, say, halfway down on the adaptive, then run a second adaptive with the bottom height the top of the first, at a faster feed-rate?
Alright Titan, out with the 'surprise' video.... Already spilled some beans may as we spill em all. How would you compare your tormach against a Haas TM2?
In my experience, Hastelloy was never that hard to mill. Its small diameter drilling and tapping that makes it a pain in the ass to work with... It mills pretty well though.
@@TITANSofCNC O ya, not knocking the machine at all! Drilling and tapping hastelloy isn't terrible on machines either. Its more of a tooling nightmare problem. Actually could you recommend any drill or tap brands you like to run in the high nickle materials??? Thanks for the reply!
More video with another harder metal cut please, i’m still not buying that tormach can cut stainless, steel, titanium like butter ? Maybe this new model 770M ? I wonder what’s the different than the old model 770 ( without “M” ) ?
You can find the spec sheets for both the 770m and the p770 and that will give you the difference. Tormach is getting ready to roll out the MX line which will have a new spindle for better holders, servos (instead of stepper motors), updated path pilot, and more.
Josh Miller when they made the part out of 4140 they said it measured really close. Also the MX and M+ line is coming with servos which may be a little better for the accuracy then the motors they currently ship with.
Modern software does wonders. Sadly most people who buy a tormach will not use the three required components. A modern toolpath - 100% climb cutting and constant step over. Good tools - variable pitch and the proper geometry for the material. Decent fixturing and minimum tool stick out. Software cost is the main issue - 30K for a seat that will produce this 3D modern toolpath.
Alvaro Gil not really true anymore, autodesk now give fusion 360 out for free to people who are small business or home shop. And the titan academy teaches fusion. I have and do still use it from time to time but you do lose a little control when compared to mastercam 2018. However fusion has a very good adaptive tool path AI.
