ну тогда учи понятие "база", что к чему должно быть привязано, в видео об этом забыли

Если учился,то учти, что фрезеровать " под зуб"( попутное фрезерование) чревато " подрывом" на выходе фрезы.

По этому ролику лучше не учиться. Он показывает как делать нельзя.

@@user-cf4lh3yf8q - В одном из планов из-за синхронизации похоже что фреза вращается в попутном направлении, но если перевести глаза на шпиндель - ясно что во встречном. Всё правильно.

Esse método não é correto, somente 1 passe com fresa, sem utilizar ângulo deixa a engrenagem sem contato em todos os dentes, irá quebrar novamente .

@@darkshow3966 não entendo disso mais no título ele diz MÉTODO ANTIGO

@@brenox1974 Sim, antigo porem incorreto, para se fazer engrenagens conicas de dentes retos sem duvida alguma complexo. Assista o video abaixo como funciona da forma correta. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--fxmdNlFnJ4.html&ab_channel=CleitonAbreu

@@darkshow3966 como pode ser feito usando outro método numa Fresadora Comum?

Та шестерня калилась, а металл этой?

@@valeravorotnyuk9283 не понял вопроса, причем здесь закалка? Кали не кали, зацепление будет хер чего, сожрет зубья быстро.

Виктор, смотри до конца, китаец потом зубья довёл как заводские, а то, что точил с обыкновенного кругляка , я заказывал у ремонтников Водоканала пальцы, маленькие валы, он не калится!

@@valeravorotnyuk9283 "как заводские"? Это и есть заводские :) . Он не на балконе работает, а в цеху. А шестерня и правда дерьмо. Тут кали не кали...хлам.

Все верно. Такая шестерня долго не проработает. Коническое колесо при помощи модульной фрезы правильно не изготовить. Нужен совершенно другой станок. А такие шестерни мы у себя тоже делали, от отсутствия станков

Very true ....but it is the "why" all this happened that is far more interesting. I was involved in machine tool sales at a young age ...in Western Canada. NOT a manufacturing center. Just maintenance machining. The last place companies wanted to spend any money was on "maintenance". The very old, heavy maintenance machines, when parts needed replacing, they bought Chinese ...cheap, cheap, cheap. Then when these machines broke down, and parts were not available, they went Taiwanese ...far better machines, but still on the level of "cheap". I absolutely hated being in this business and got out. But what WAS interesting was the evolutions of the machine tool manufacturers globally. The Quality Europeans builders, who really knew their stuff, could not and would not compete "price-wise"....and that's all the company I worked for wanted to sell ...in Western Canada. I watched the many Asian companies flourish. The top Quality, mid quality, and cheap Quality, ....all had their place. But if a customer wanted "cheap" ....which was usually the case ....I had NOTHING to offer. I hated this industry/job so bad ....when management/family were do clueless of the industry needs. There is only a limited need for Lamborghinis and Rolls Royces. Love machinery ....but hate the industry. I have to add, this Hitachi mill has seen its day, and when an arbor gets damaged as this one is, it is very telling of what this machine has been through. .

@@taxicamel The biggest strength of Chinese companies is two fold. One, they are extremely "adaptable". You want an electric relay and ready to pay $2,000? No problem, we'll make it for you and make it well. Oh, you only have $100 for the same device? NO problem, we'll still make it. And the fact is it can work for 2 hours or two centuries, it's a lottery. And second strength kind of stems from the first. They don't care about their company's "reputation" or even brand name. You don't want to buy from Chang Ming Ying because they sold you crap? No problem. We'll just form the "world leading" Ying Ming Chang and you will buy from us without even knowing it's us. As an example, King Long bus company is also the Higer bus company. Ask any sales person and he or she will deny they are even related. What's really missing on the market is "the next best thing", machines and goods of, say, 70% of German quality (which btw plummetted A LOT recently) and the price of 50%. As an example, you can buy an LG washing machine for $500 and it'll give you 5,000 cycles (if you're lucky). OR you can buy a Miele for $1,999 and it'll give you 30,000 cycles. But there is NOTHING in-between. The country/company that manages to conquer the middle of the market will win BIGLY. Oh boy, did this turn into a rant :-)))

@taxicamel- you and the guy following you just made my day. Didn't have to look long for the know it all essay.

Thank you for your comments and support. I'm surprised you did this work in the 80's. You must be old?

@@thdVn I am. Lol. Mid fifties. Keep up the good work. There will always be a place for a manual machinists. And Rember Knowing how to use the right materials and the right way to harden and temper and when to and when not to, is all part of making good reliable part's.👍

@@thdVn I did this in the early 70,s More manual then

Не вал, а оправка!

- А вы не на оправку или вставки смотрите - а на то бьёт или не бьёт сама фреза.

- Сказал же что будет закалка, вруби субтитры.
