I usually present you a video lesson on the education of engineers and just

00:00:12

production workers today we have such a fascinating topic

00:00:17

The countersink design of the purpose of the countersink is different from the countersink because

00:00:25

many questions than life inquire is still different from a countersink

00:00:29

close values are so similar and how are they similar or different today

00:00:36

all this we will consider by the way do not forget to look and GOST 12 489 service 71 is 1

00:00:45

71 years old, which concerns a vertical drill and so is a vertical drill what exactly is a vertical drill yes yes guys

00:00:54

you were not mistaken this is not a drill before you it is

00:00:57

countersink although if you look at this part that goes to the shank calibrating

00:01:04

part of it seems that this drill at first sight

00:01:07

but when you look at the cutting part you understand that

00:01:11

and where is she actually this is the cutting part and so the countersink is a special

00:01:18

metal cutting tool

00:01:20

with several blades, namely with several blades, in principle, as for

00:01:25

many axial cutting tools from here from this view we can more

00:01:32

consider that the cutting part is not here such a western cone which

00:01:40

can work, so to speak, on virgin soil for metal which before

00:01:47

processed well in terms of not just not processed but

00:01:51

was not drilled, that is, it was integral with such a tool into this metal is not

00:01:57

drill do not pierce it about run zinka and so the purpose of a vertical drill is half

00:02:03

finishing of holes in pre-drilled parts and workpieces with

00:02:08

the purpose of adjusting the diameters to the desired value and improving the quality of

00:02:14

surface precisely improving the quality of the resulting surface

00:02:19

the main objective of this cutting tool is also countersinking

00:02:25

similar to drilling a rotation of a tool around its axis with translational

00:02:30

motion of course yes in most cases the rotation happens exactly

00:02:36

the most vertical drill but you should not exclude such

00:02:40

options such as using on lathes in such cases or

00:02:47

turning turret such cases the tool is stationary

00:02:51

state and the part rotates the feed, respectively, the tool goes and he

00:02:58

enters the part along the axis and so the Zenkin design we take here what we are now

00:03:07

saw a vertical drill this is a classic yes denker further we will consider

00:03:13

several types of such a tool unless of course this video picks up enough

00:03:18

likes so don’t forget to slap right now this like under the video

00:03:27

the same design, note that in principle the part that serves

00:03:34

the base part to the shank this is the foot they are no different from the drill

00:03:40

with a tapered shank there is also a so-called neck

00:03:46

jumper between the working part and the base

00:03:53

further we see that since we have already begun with this part, going further goes after the neck

00:04:00

there is a calibrating part that flows into the cutting part

00:04:05

part of the cutting but because there are cutting edges, namely three

00:04:09

cutting edges on this countersink here to see this view and that is, in the morning we

00:04:16

from here we get just such a picture of a ripper, in principle, it’s all calibrating

00:04:23

the cutting part is called the working part there are a total of these two parts

00:04:27

as you can see, the same is in the geometrical parameters of the core drill that

00:04:35

the corners here are more like that but more untwisted, turning more like this

00:04:40

twisted yes it turns out that the chip goes to the countersink chip removal much

00:04:49

easier than turn it over but not at startup it is worth considering that under

00:04:53

drilling allowance is equal to half the diameter that we drill and in

00:05:00

the vertical drill remains an allowance of just a few tenths of a millimeter like this

00:05:08

here is a drawing of Zenkin, and if you want to develop good drawings, not only

00:05:14

2 grandfather but also in 3d format follow the link in the description and select the course

00:05:20

which one you like most drove the destination countersinking operation

00:05:28

countersink operation countersinking consider goes the first thing that I tell you

00:05:35

already said a hole is drilled then in most of it she’ll drill faces but

00:05:43

this is not necessarily well done so to speak for

00:05:48

an increase in tool life immediately drill for large diameters is not quite

00:05:52

practical and long so it’s easier to do two drilling and reaming operations

00:05:57

and then it’s for reaming for ending with such a drill here

00:06:04

the entire length of the hole thereby increases slightly as I already

00:06:10

spoke at a few tenths of a millimeter the diameter itself but significantly improving

00:06:17

purity of processing and geometrical what is important parameters of internal

00:06:23

holes and so the purpose of the vertical drill we consider such we are already with you common

00:06:30

you have considered the appointment and now, in a little more detail, this increase

00:06:34

accuracy and quality improvement as I said them surface treatment

00:06:39

holes before threading and deployment deployment this is already

00:06:44

the next operation after countersinking goes the same is aimed to improve

00:06:50

surface quality by the way improving accuracy is achieved in well practically

00:06:58

if I take de classes for classes of 9 degrees, I apologize for degrees 9 degrees for sure

00:07:05

glass roughness and then consider the second one is pre-calibration

00:07:10

drilled holes for bolt pins and other types of fasteners

00:07:14

that is, for such holes that are designed for studs and bolts and

00:07:19

other fasteners the countersink can become a finishing tool after

00:07:25

which you don’t need any machining

00:07:31

carry out countersinking at what machining operations

00:07:36

carry out countersinking to do on what operations on drilling machines of all

00:07:41

types of natural drilling machines is a very popular tool no less

00:07:46

he is also popular on lathes well why not less popular because

00:07:52

in principle, this is a good and quick way, well, most likely on a turning

00:07:57

uneasy turning universal and she turning lathes

00:08:02

very often used Zencor to improve the class of cleanliness and degree

00:08:09

accuracy of the resulting hole but universal probably prevail

00:08:13

still boring, although with small diameters it is better

00:08:16

use land on boring machines well naturally boring can

00:08:23

used on machine units as an operation in an automatic line

00:08:26

there are automatic lines where, for example, there are some drilling heads where

00:08:32

is there 1020 with holes and 20 drills respectively they are light for 25 she

00:08:39

the next machining operation this part moves and

00:08:44

20 holes are improved immediately with 20 gum ditches the next one can

00:08:51

to be deployment or maybe it is finishing if these holes

00:08:56

for bolts and other fasteners for horizontal and vertical milling

00:09:02

well, in principle, also a vertical milling machine

00:09:06

it also has a rotation have a table move and you can use a countersink if

00:09:12

there to fix some kind of body part so the main question that I

00:09:19

ask my subscribers my readers of my blog channel who are watching people than

00:09:28

differs the countersink from the countersink that's interesting yes here is the countersink let's obviously

00:09:33

I’ll show you everything will become clear here countersink that's what actually

00:09:38

occurs in the process of cutting Zenkin exactly passes through the holes what we

00:09:44

previously considered but the countersink that we went through in the previous video

00:09:49

00:09:53

forget to sign up if you haven't signed up yet this one

00:09:58

countersink and countersink as you will see the countersink in its processing does not pass

00:10:05

through the hole it makes a chamfer it is made it is a blunting of the edge in

00:10:11

hole in some cases and some types of countersink that we are with you

00:10:15

already passed they can take some kind of pad under the fastener

00:10:19

but they in no case do not go through the holes they do not improve its quality

00:10:25

and do not increase its diameter roughness class after zombie class

00:10:32

roughness after a call uring a little touch on a little bit of this topic

00:10:36

here is such a label of purity classes as it is called purity class

00:10:42

countersinks they are also rough and fair but we do not consider rough

00:10:47

in principle, a roughing is interesting for us because it is

00:10:52

an operation that is rarely used in a dream, it’s such help since

00:10:58

sounding that is somewhere that seeks

00:11:02

we owe class six on average gives us a vertical drill in normal conditions on ordinary

00:11:08

equipment ordinary so to speak with our hands in some cases very

00:11:14

joking jokes are shorter here look 6 accuracy class roughness we can achieve

00:11:21

Grades 3 and 2 7 are already 16 well, in principle, I will not say so I have not met one of 6

00:11:29

such a vertical drill but we don’t apply such and even in principle it’s already

00:11:34

more equal closer to the sweep to 16 to get it probably a sweep

00:11:40

it is difficult to obtain such a roughness with a vertical drill only if, of course, the vertical drill is not

00:11:44

some you have imported super mega high-quality and I have all the guys

00:11:50

subscribe to the channel like start necessarily

Вы смотрите канал Веселый инженер. Сегодня зенкер будет в нашем видео уроке, а именно зенкер по металлу. Этот инструмент достаточно популярный и заслуживает нашего внимания. Если вы хотите посмотреть размеры данного инструмента, а именно Зенкер ГОСТ вам в помощь. Если вам по вашему техпроцессу необходимо улучшить отверстие, то это обработка зенкером. Конструкция зенкера отличается от сверла совсем малыми конструктивными особенностями. Когда впервые увидел зенкер чертеж его меня не впечатлил, но я отметил для себя, что он весьма похож на сверло. Очень важный вопрос это зенкер и зеньковка, а именно чем они отличаются. Обработка отверстий зенкером производится практически с применение таких же режимов резания. Существует такое понятие как зенкер под сверло оно говорит о том, что под определенное сверло существует свой ГОСТовский зенкер. В моем видео вы увидите зенкер фото его работы и многое другое. Если говорить о конструкции, то части зенкера весьма похожи с его собратом сверлом. А элементы зенкера отличаются от сверла только режущей частью и винтом стружкоотводящих канавок. Отвечу в данном видео на главный вопрос моих подписчиков зенкер и зенковка отличие. Ну что тут скажешь зенкер инструмент который значительно повышает класс чистоты и снижает шероховатость. Такой режущий инструмент как зенкер должен быть в каждом производстве и предприятии нашей бескрайней родины.
