Have you ever heard of Okamoto's Grind-BIX accessory that is supposed to cause a coanda effect? It's supposed to increase coolant permeability by a lot.
Sir needs your support I India for application in grinding process
I don't like is real. They own everything and we are their slaves.
hi do youu need air knife?
I am I new one here?
What is the feed rate you recommend in terms of feed rate per work piece revolution? I am running a 3m CUBITRON 80H at .0007 per rev typically at 65 SFPM work piece speed and 8750 wheel SFPM. I shut the feed rate finish down to .00015 per rev for the last .002-.003 and cut workpiece speed in half to achieve an 8-10 micro inch finish. But this doesn’t seem like anything close to 600mm/min. What am I not understanding? Usually grinding shafts with three to six different diameters on a KELLENBEREGER 100. Dressing .0003 once each part. At .0007 per rev I am throwing flames, part stays cool, Wheel horse power meter shows virtually no load, maybe 3-5% over idle wheel. I have been grinding 45 years, this is my first experience with ceramics. Seems like your 600mm/min is off by several orders of magnitude. What am I missing? My math comes up with 21 mm/min.

this is so cool!!
Sir Can you tell me RPM and Feed Use for material SS316L in 4mm Cobalt drill and depth 90 mm Use in VMC 3-Axis Machine This machine is not through coolant machine Drill Details 4mm Cobalt drill dia. and 120 length (HSS-E PFX Extra Length Dril) 2RG4369627 Bright Finish DORMER DIN 1869/1
Guys this video is gold. Hats off to whoever chose and composed the music. Visuals are spectacular. And thank you for 'subtitles' For those that can read it means no annoying and laconic voice over.
Is this about skateboard trucks?
What is this steel? Is it possible for hard steel?
Good morning Dr. Badger. In your opinion, the roughing wheel width must be higher than the radial DOC? Eg. Grinding a diam 20mm down to diam 4mm (radial DOC of 8mm) is feasible with a standard roughing wheel of 6mm width? Thanks Alessandro
Is it hazardous to your hearing? What decibel level is produced?
Finally i met you hancock i dare not call u an a$$hole
What's the solution in the tank?
I'm a student at Bahir Dar university, Ethiopia doing a research. Could anyone help me get an ultrasonic transducer and horn (vibrator) with a variable frequency. The item shall have control and display units.
Hello. IS there any tutorial about how to replace a tool when the tool life alarm pops up? thank you
How if to clean liquid like milk or jus ?
Great vid! Would you have any idea why on my CNC lathe I get chatter when facing? My part is not sticking out more than 1x D....I can't get faster than 2000 rpm on this lathe. Seems to happen alot when facing. The machine is about 7 years old. We mostly do Stainless.
Wow😮
9 year-old presentation wtih limited views; yet good advice. My application is also in sharpening of chain saw cutters. The mid range of quality machine I use came with the stupic pink ceramic bonded AlO type wheels. Even with care to clean chains, it required constant cleaning and reshaping of the disc. The CBN wheels I substituted are far superior in that they retain their profile shape, cut with less pressure and time which adds to their inherant cool cutting properties. The CBN gets dirty way less often (remember, I clean my chains first) and when darkened with chain crud an art gum eraser.
great dishwasher
Kiwi?
I tried this one at work the other day and the results did not match my expectations. We had three lobes (our normal is two). Wheel speed 1500 rpm work speed 500. So I changed to 533 rough and 55x for finish speed. Made sure both numbers were irrational. But the lobes still appeared. What did I do wrong. We were doing a OD roundness lab check, and this change did allow us to pass the check, but the lobes were still present, if fuzzier. I was under the impression they would be mostly eliminated or much less pronounced. For context, I perform plunge OD grinding for cones. The workpiece and the grinding wheel sit at angles to one another (different angle for different products it changes frequently). So perhaps the various work speed relative to the diameter at any given point has something to do with this?
I have found the holy grail of channels! Thank you!
Hiring operators with big tits doesn't hurt either
really fascinating
Might need to give the machine rotator cuff surgery.
This is so cool!
approx how much are these??
550-750k
👍💯👏
Awesome
I am so disappointed that I have not found one video One video that uses this to actually clean a pan full of carbon. Can someone please make this
Physics yessir
What happens if air is trapped inside a part?
its like magic. dentist use this technology to clean tartar on teeth.
what kind of liquid is best to use for such mujek? does it react with aluminum?
Part 3 ?
wow this is so cool! :)
عمل رائع
@2:03 Why is the cut deeper when workpiece RPM is slower? Plunge speed is the same, then the cut deep is the same, and slower RPM makes the chip smaller?
Because the depth of the plunge will be more per each rotation of the work piece since it is moving slower.
its a brain bender... try and picture it as gears. if the grindstone is spinning faster than the work, its drawing an arc through the work. vice versa, if the work is turning faster, its the work drawing the arc through the grindstone. only when two gears are the right size and pitch do they contact at the ideal pitch line... obviously the stone is spinning much faster than the work. the difference in arc length is minute but its there.
very. helpful.
thank you so much
❤️❤️❤️❤️
Thanks for sharing
Cool stuff...
Where can a student get dedicated training and experience with micro machining?
Amazing video helped me to teach how actually and accurately these ultrasonic waves work in a fluid to clean machine parts
Please tell us how to offset and operate
