Как правило, это доп.опция на современных станках с высокой точностью синхронизации вращения шпинделя и стола

@@alexklgn1002 как правило такие станки стоят от 50млн руб. исходя из текущий цен на 06.07.2021 и если рассматривать серийное производство то дешевле делать зубофрезерным, чем покупать станок за 50млн.

Ну... Быть пятиосевым, как минимум... Чтобы можно было подвести инструмент под определённым углом. И, насколько понимаю, иметь хорошую синхронизацию между шпинделем и приводным инструментом.

Проще и дешевле

I was thinking the same thing. You would never use CK45 for a component that large. Of course, it is easier to machine.

Why would one not use CK45 for large parts?

​@@impactodelsurenterprise2440 Yes you would, these guys dont know what theyre talking about, it all comes down to the application type, CK45 conforms to the AISI 1045 composition. It's used for most transmission and motor parts of medium strength. Case hardened parts such as camshafts, gears, rocking levers etc. Simple hand tools and various types of fasteners and fixtures, machinery parts and components with medium stress. Surface hardness of 57~62 HRC can be achieved with case hardening to a depth of approximately 1mm.

@@miguelcontreras5782 Exactly. I have seen a drawing calling out for through heat treatable carbon steel for what is essentially just a non load bearing bracket. Another even calls for non existential material size. And these are coming from large MNCs. Makes one wonder...

they they would have a hard time showing anything as its drenched in cutting fluid.

Well... Maybe, there's a gear grinding process in further operations, so no need in a good surface finish. In our workshop, gears are being made with allowance for further gear grinding, as they are going through carburizing, hardening, shot blasting, some machining inbetween, and at the end there's a gear grinding.

Fack, you work in aerospace?...try some real world mechanics, fit is what matters
