MASTERCLASS | Top 3 Grinding Techniques Used On The STUDER S41

[@mohammedalbattal77]

I just finished watching this video. I can only say one thing... Mr. Chris, you have taken the education level to a whole other level... Most of us as a milling machine operators don't know much about these super machines.... Thank you and I hope to see more of these videos here... to be Honest despite my poor English... I can always understand your very clear explanation... and i know the secret is because you are so sincere in your love for spreading knowledge.... Thank you are all TITANS OF CNC BOOM 💥

[@christophervillalpando5865]

Thanks for the support! The easiest people to teach are those that are willing to learn! Greetings from Texas!

[@barrysetzer]

Great video Chris, i love simple explanations of complex processes

[@simpleallrounder2115]

Greetings from germany 🤘 Very good demonstration and explanation. My profession is called: Schneidwerkzeugmechaniker Schwerpunkt Schneidwerkzeug- und Schleiftechnik (Cutting Tools Mechanic - Main Focus - Cutting Tool & Grinding Technology) I've learned manual, nc and cnc grinding for milling & turning tools (and a lot more) of metal, wood and plastic. It's nice to see same techniques at the same quality on the other side of the ocean 😁 Keep going 🤘

[@trevorgoforth8963]

Nice job Chris! I can imagine a video like this is invaluable for someone looking to enter into the world of grinding!

[@TylerTITANSofCNCTippit]

Great job Chris! This video is jam packed with information. I love the addition of marking the part so we can visualize the grind!

[@travisjarrett2355]

Great video Chris. That taper adjustment in the software is nice!

[@benjaminordonez779]

Chris, Your always on point with your grinding information. Thank you!

[@z0phi3l]

Great video Only suggestion, and not a popular one, but switch to metric, numbers will make a bit more sense and also be better for international viewers, we need to get on the metric standard like yesterday

[@AChicken-sh1gc]

a little more ? i have tried to learn imperial for 4 months now and its just as confusing as it was 4 mo ago

[@Sara-TOC]

You are an excellent teacher Chris! I appreciate you explaining what's happening with the machine throughout operation.

[@christophervillalpando5865]

Thanks Sara!

[@jacobadkins5164]

I run these and I there’s a legend of a man who’s like the king of them, he’s 65 and has been grinding for 47. Studer has offered him jobs. Amazing because he grinds way different that any video I’ve seen

[@shaniegust1225]

Nice video Chris, keep up the great work! The Grinding Academy looks amazing 👍

[@NOBOX7]

Titan is so awesome he has to pay other people to be amazing for him because he has to many other jaw dropping things to do

[@SinumerikcncvmcRAJASTHAN]

Wow excellent 👍

[@Zeuspwns]

Love my S31s and S21s, interesting how slow your feeds are considering it is between centres, still good to see Chris

[@michaelarnold1576]

I'm a centerless grinder Cincinnati grinder machines the spark out form is the same form I use when I'm holding the handle down pretty neat good stuff I like the video

[@erubielbanda3525]

great video...what is the oil based coolant you are using? Do you have heat issues on certain materials?

[@IVIasterify]

You could do a video of top 5/10 things you would want Mechanical Engineers to know about CNC parts. I am a Mech.Engineer and designed many CNC parts but I have never visited a Machine Shop 😅

[@TITANSofCNC]

Great suggestion! Thank you for your support 🤙

[@Nuck-Chorris]

I worked many years on a Studer S33 (now Danobat Overbeck) and I can say there is no advantage by multi plunge grinding. Pedulum grinding is more efficient and a lot faster when you calculate the correct settings for dressing, feedrate, rpm,…

[@storyofmurugan3524]

Can share gear grinding video like gleson pfatuer, hofler machine

[@bookwurm99]

Why do you have coolant going on the head stock center? Doesn't need it since it is live. If the center was dead itd make sense. Have an S41 at work next to my grinder.

[@jmowreader9555]

Chris, two questions: Question 1: Can you explain, perhaps in a video, how it's decided when to re-dress the wheel? Question 2: Does your Studer have automatic wheel wear compensation?

[@christophervillalpando5865]

Question 1. Welcome to grinding sometimes a dress is needed after a few thousandths and sometimes it works better to let the wheel load up (The finish tends to get better after a few grinds). The biggest reason I use it for is to compensate for shoulder breakdown (to hold lengths), Radius breakdowns, and of course when the wheel is producing a bad finish, burning the part, or not grinding away what I adjusted for. Question 2: It does, it has its own wheel technology page that can give you all the information you need. Hope this helps! thanks for watching!

[@Resnor]

Hey buddy! I am gonna talk in metric right now. You should re dress your wheel 0.03mm from size. This will reduce flecking and give you a better finish. But! if you want a better finish do the same in cycle dress but leave another 0.03 on the part. Finish the part with an oscillation of 0.3 at 30 with a dwell time of around 10 seconds. Very nice finish! wheel wear compensation? Dressing compensation yes on studers. If you wheel is wearing during grinding and a dress is not sorting this out then your wheel,speeds feeds,coolant need a look at.

[@christophervillalpando5865]

@@Resnor Great info you shared there! I see you in some other comments its cool to get some positive feedback and other tips. This is the platform to learn and teach on! I don't like to dress that close to size depending on the material and wheel it can easily cause the wheel to take off to much on the final approach because the wheel is sharp. But that's my own experience I've had better luck with dressing after the roughing, letting the wheel load up from the semi finish and then finish the part. Hope to see you around!

[@avorock]

It would be interesting to know the roughness of the surface finish after the grinding (Ra in micron). GG guys!

[@christophervillalpando5865]

Sorry we did not show that this time around but I had it checked after and it was a 7.8 Ra. Off camera I played with the dress and got it down to a 1.8RA for fun. Brushing the wheel and applying some preload to the wheel!

[@Resnor]

If you are wondering about a micron conversion its roughly 0.2 and 0.05 the later being a super finish.

[@avorock]

@@Resnor Thank you for the conversion :) What's the original measurement? Sorry for the ignorance but I work only with micron in Italy.

[@avorock]

@@christophervillalpando5865 Wow, pretty good finish straght from the grinding, excellent work.

[@Resnor]

@@avorock hi buddy. so Chris checked the surface finish at 7.8 micro inches. This converts to 0.198 um. This is the finish out of the machine. Like he said for fun they got it down to 1.8 micro inches or 0.045 um but thats not really a repeatable finish over many parts. 8u in or 0.2 um is considered a good grinding finish. Below that you are in super finishing territory.

[@rednecktech9485]

What is the purpose of sparkout?

[@christophervillalpando5865]

It allows the wheel to dwell on the part and cleanup the grind. As it sparks out the pressure/deflection is released before it kicks the wheel out. Great question!

[@fmgee1959]

It’s a good way to control geometry and size. If there’s pressure between the wheel and the workpiece, making adjustments can be like chasing a rabbit. The spark out allows predictable adjustments because the pressure between the surface was reduced as much as possible, eliminating a variable in the process. We were working on a tight tolerance taper and I’d have the grinder adjust his table to take a tenth of the front, a tenth off the back, two tenths off the back and on and on. I suggested taking five park out passes and it got the machine dialed in because the cutting pressure was throwing out the position of the part.

[@rednecktech9485]

@@fmgee1959 Thank you for the excellent reply :)!

[@MrJugsstein]

Ok I get the corrections but why the taper in the first place ? Can you expand Thanks 👍

[@christophervillalpando5865]

Taper happens for a number of reasons. You can grind one part straight change the setup and you might be close but not perfect on the next setup. Wheel breakdown can also cause a taper and that cant be fixed using the micro adjustments but in the dressing. Grinding is high precision and sometimes as tight as .0002 or tighter and grinding over a long width there's not much room for a variation. Hopefully this helps clear up the question you had. Great question!

[@AlexLancashirePersonalView]

Does the machine have overload protection in case you misprogram your fast feed?

[@christophervillalpando5865]

It has a sensitron that picks up the actual grinding of the part. This is why its important to monitor the grinding and watch for burning or excessive feeds

[@marcoprimo4042]

Is there any modern text books or manual on grinding??

[@TITANSofCNC]

Great question! Check out www.grindingacademy.com/

[@kleini3]

In german it’s called „vademecum des Schleifens“ from the publisher Hanser Verlag. I really like it. Many examples and even some depp dives in the physical and mathematics of grinding but great for a overview too !

[@whatcher8151]

at first you brought the word OD in relation to the length correctly as proposed then at 10:15 you we have 5 inch OD. here you didn't specify a 5 inch taper length with the proposed taper. I knew what you meant, others may question or get confused, rightfully so.

so this grinder uses dead centers instead of live? interesting, i would not have guessed

[@christophervillalpando5865]

Yes we use dead centers on the S41 we haven't done friction drive grinding yet.

[@lexluther1323]

This machine seems pointless

[@5eZa]

how would you propose to do OD grinding then

[@toddprater14]

With a old Parker majestic universal grinder or a Warner and swayze… this machine seems a waste , I’m sure it works in way more complicated parts , but titan just wants everything new and cnc …you can do all this on older Detroit built grinders just as efficient..

[@andrewavelarful]

Have you ever see an error on set up? Code $1902

[@christophervillalpando5865]

According to the manual for the S41 its for an Error while updating the wheel. I haven't seen this code before but Id recommend redoing the setup of the wheel from the very beginning, If you can.
