Engaging Presenter, It’s refreshing to learn from someone who genuinely loves the subject matter.
I love how the video incorporates real-world examples, helping to apply the concepts in practical scenarios. Thank you sir!
Your lathe machine tutorials are fantastic, Prof. Johnny! They're so easy to follow, and I've learned a lot from them
Glad you like them! Thank you, John.
Thank you, Prof Johnny for the detailed step by step procedure and the information about the two method which is the chasing dial method and the forwad reverse method.
By watching this video, it helps me to learn a lot about the capability of the lathe machine. Looking forward to have more videos like this!
Marami akong natutunan, napakadali ng kanyang step by step procedure na tinuturo at madaling intindihin. Maraming salamat po!
It gives me more knowledge on how to do the threadings! Thank you sir for making it much easier to learn for us students!
Your tutorial videos are excellent! I learned a lot! From Bentabal, BSME 1-C.
This video is exactly what we need for our project. Thank you sir, this is very useful☺️

Good day. I want to learn how to operate a lathe machine. Where and what school is that. Thank you.
Hi Jose, GOODWILL TRAINING AND ASSESSMENT CENTER INC. blk 48 lot 14 Justice St., Goodwill Homes 1 San Bartolome, Novaliches, Quezon City. Thank you and God Bless!
Sir thanks po sa additional knowledges, tanong ko lang po may chart din po ba para sa inch compound rest settings. Thanks po.
Hi Miguel, meron din sa inch kung ang tinatanong mo ay para sa threading.kung kelangan mo ay pwede ko send sa u. thank you for watching my tutorial videos continuously. keep safe!
Kung okay lang po sir, thanks po in advance 👍.
@@miguelsaguid1319 Hi Miguel, san ko pwede isend yong request mong chart?
Pls can you give a video lesson for compound rest setting for threading of 50 degree Graduation . Bcz till how many ships i sailed i found a lathe in 50 graduation.
Kindly take a picture of the compound rest of your lathe machine and send it to me so i can give you a better advice. Thank you.
Dear sir, good day. Here I can't attach a photo of the my lathe compound rest slide Graduation. Plz may i have another alternative way that i may communicate with YOU. It will be a great help for me.
Dear sir good day. In your video, seen you set the compound rest in degree. Why you did? How YOU set the degree in compound rest plz explain. For inch how many degree we set if compound rest have only 50 degrees in left and right.
Hi Mitu! when you are going to cut 60° thread, you may set the compound rest half the included angle of the thread or 29 to 30 degrees to right for a right hand thread, and to the left for a left hand thread. But the reading in the compound rest of the lathe is 59 or 60 graduations. But since your lathe machine has only 50 graduations on its compound rest, you may need to use some aided device such as steel protractor to set the compound rest to the required angle. Thank you for subscribing and for your question. I hope i answered it clearly.
@@profjohnny8624 this 29 will be calculation by 90-29=61 degrees? For bsw thread (55') how much will we set for compound rest? Pls can you give a video lesson for compound rest setting for threading of 50 degree Graduation . Bcz till how many ships i sailed i found a lathe in 50 graduation.
Hello sir please drill cutting edge grinding prepare agale
Prof. Sa machining po ba tinuturo din ung cnc machine operator
Hi Aquila. Sa aking training center ay conventional machining lang. Thank you and God bless!
Hi Prof. Johny, thanks for videos, a great series of machinery. 8 go a question, which of two methods cause more wear in split nit , chasing dial or forward reverse method? Or both of them cause the same wear. (You say that part in your own language 😉 I cannot realize)
Hi Mr. Mehdi, firstly, thank you so much for watching and subscribing to my youtube channel and asking such question. The forward and reverse method in thread cutting could easily wear out both the split nut and lead screw since they are engaged all the time during threading operation.
@@profjohnny8624 yes, you're right, it's engaged at least twice the other method. I doubted because when the carriage is return omg to right side of worpiece , since the cutter is not cutting and there is almost no load on the split nit and screw.
Sir saan po ang training center nyo
Goodmorning thom! dito lang sa blk48 lot14 justice St. Goodwill homes 1 San Bartolome Novaliches Quezon City, or pwede mo rin gamitan ng waze (Goodwill training and assessment center inc.) Thank you for subscribing.
Prof,pinapalitan din po ba un worm gear sa dial?
Yes John Ray, kung ano ang required na worm gear para sa gagawing thread ay un ang itatapat sa lead screw. makikita un sa label o plate na nasa harap ng dial. thank you for watching and subscribing. keep safe and God bless!

Magandang araw sir. Paano mag thread sa Cosmo ace mitsuhata LMD-2000 lathe machine?
Hi Justo, kung CNC lathe yan ay gawin mo muna ang program ng para sa thread. Pero kung conventional lathe ay gayahin mo lang yong tutorial video ko tungkol sa Setting Up the Lathe for Threading at How to Cut V-shape thread in the Lathe Machine. Thank you for watching and subscribing.

Sir tanung kulang po bakit po 1.85mm depth of sa compound rest e ang actual ay 1.63mm lang aning pong reason sir? Gusto kulang malaman kasi ngayun kulang nakita ang ganyan idea. Salamat pagsagot
Hi Anthony! 1.85mm dahil nakaset ang compound rest sa 29°. natural lang na hahaba ang distance mula sa zero degree na set up na may distance o lalim na 1.62mm. kung paano nakuha ang 1.85 ay kelangan gamitan ng Pythagorean theorem. C=1.62/Cos29°
Sir tanung kulang po bakit po ba naka set yung compound rest as 29degrees pwede po ba kahit sa 90degs. Ang set up makakuha parin po ba yung thread ng tama?
San banda training center nyu sir

Sir paano nyo nakuha yong 1.62 na thread depth nya.. Ano ba formula nyo.. Salamat po
Hi Enrique, the formula is on the last part of the video, please go over the video again. thank you for subscribing.
Hi sir paano po yung starting point gap ng workiece bago mo sya ingaged
Hi Allen! pakireword mo nga yong tanong mo para masagot ko ng tama. Yon ba layo ng toolbit sa workpiece bago iengage ang split nut lever? or lalim ng pakain (depth of cut)?
@@profjohnny8624 hi sir thanks..i mean sir yung distance ng toolbit from live center to work pice po..hindi po kya mabura yung thread nya pg hinde nakuha yung distance nya TIA sir
Gamit ko kasi sir na formula which is TD= 0.613 X Pitch Correct me sir if im mistake. Thanx po Halimbawa: M24X30 Td=0.613x30 = 1.839
Yan ang luma nating formula Enrique, nong lumabas ang new ISO metric thread ay naging .54127 x pitch na.
Hello sir paano po ang pag set up ng lathe threading for 11G 5/8" hindi ko kasi makita sa machine chart
Hi Ernito, sa inches threads mo tingnan ung 11tpi, kung wala talaga nakasulat sa thread chart ay yan ang kulang ng lathe machine mo, may mga lathe kc na hindi kumpleto ang pitches ng threads, thank you for subscribing. God Bless!
Noted thank you sir
Saan po pwede school niyo?

Boss walang revers
Sir johny diba 60degre yung tread bakit po 1.87 naka lagay naguguluhan po ako sir maraming salamat po sana ma pansin nyuo po
Hi Ramil, saan ba nakalagay ang sinasabi mong 1.87? wala ako makita sa video, baka ung 1.85 ang sinasabi mo which is the DEPTH SETTING of the compound rest set at 29° when cutting 60° external thread. Gamitan mo lang ng Pythagorean theorem. Ang actual na depth of the teeth of thread is 1.62mm. kung sinet mo ang compound rest sa 30° ay magiging 1.87 ang depth setting ng compound rest. Malinaw na ba Ramil? Thank you watching and subscribing.
Good day sir prof. Johnny, do I need ba? To enroll in TESDA - before going to Goodwill Training place.tks
@@josellanera6082 Hi Jose, sorry for my late response. No need to enroll in TESDA, you may proceed directly to Goodwill Training and Assessment Center Inc. Thak you and God bless!
Sir bakit pumapatong twing uulit ako Ng pakain...
Hi Pogz, maraming dahilan kung bakit pumapatong ang pakain. Una, baka metric ang lead screw ng lathe mo at ang thread mo naman ay inches. Pangalawa, baka ung nakaengaged ng worm gear ng chaising dial ay sa lead screw ay hindi tama ang number of teeth. Tingnan mo sa plate na nasa harap ng chasing dial kung anong number of teeth ang worm gear para sa picth ng thread na gagawin mo. Pangatlo, Baka mali ang LETTER or NUMBER twing iniengaged ang chasing lever sa tapat ng reference line. Makabubuting panuorin mo uli ang aking tutorial video tungkol sa THREADING OPERATION (external). Maraming salamat sa panunuod at pagsubscribe. God Bless!
