- Hello everyone FRIENDS! You are watching the channel Cheerful engineer.
And today is a vertical drill. And by the way, this is my 100th anniversary issue on the channel. Countersinking cannot but be considered by me. Indeed, in mechanical engineering there are types of countersinks that you may not have used, and you probably didn’t know about some. Perhaps you are a student who on the exam heard a question, name the types of countersinks and could not answer this ticket, then this video lesson is for you. When the types of countersinks for metal were designed, then I think that they tried to take into account all the nuances of machining. You can often find on sale a set of countersinks of various diameters and it is very convenient for a turner or a worker in garage communities. If you have a kit, then you will have no difficulties how to choose the diameter of the core drill that is needed. But I’ll tell you for sure that hole countersinking is necessary to improve their quality. But to say that drilling countersinking holes is a normal process. If you are accustomed to drilling a hole without additional processing, the coredrilling tool you need, because the coredrilling does not require much effort on your part. But if you are developing a technological process, then the countersinking operation should go right after drilling. Indeed, the main purpose of countersinking is to improve the quality of the surface in terms of size and surface finish to 6-7. If you need to choose an allowance for countersinking, then it is given in this video tutorial, I think this information will be in demand. And so before proceeding with the countersinking process, do not forget that before that you need to drill a hole for the countersink of the required diameter and you already know how to do this, unless of course you carefully watched my videos.
