Tutorial on sharpening computer engraving knife:
1. When the engraving knife of the precision engraving machine is placed at a smaller angle than the actual angle on the sharpening machine, for example, when grinding it at 10 degrees The knife should be placed at an angle smaller than 10 degrees on the knife sharpener, and then the half-opened surface in the first step is perpendicular to the grinding wheel, and then tilted about 10 degrees on a vertical basis, that is, it is 100 degrees from the grinding wheel. (Note: The larger this angle is, the sharper the knife will be. If you are making steel, this angle is not suitable for being too large). Just make sure that the grinding wheel surface is parallel to the angle of the tool (it doesn't matter if there is a slight error).
2. If it seems to be far off, adjust the angle between the open half surface of the tool and the grinding wheel surface appropriately until it is parallel, and then slowly feed the tool on the grinder until the grinding wheel surface is in contact with the tool. The angles overlap. Only when they overlap can the angles grinded out be accurate.
3. To make the tip of the knife, you need a slope in several directions for pin rowing. The slope here is 2 to 5 degrees. When carving steel parts, make it smaller and make soft materials (such as copper, aluminum, etc.), the larger the angle, the sharper it will be.
4. Avoid the air. Be careful not to sharpen the tip of the knife when avoiding the air. If you have good knife sharpening experience, you can manually avoid the air. When measuring the tip of the knife, measure it before the gap. If you want to sharpen a 0.2mm knife, when measuring with a caliper, it cannot be exactly at the 0.2mm position. It should be slightly smaller by a few wires. This value depends on the angle when sharpening the knife edge ( That is the 100-degree angle mentioned above). The larger the angle, the smaller it is, because there are more secluded spaces on the right
Beginners learning to use computers should first learn typing. The eight basic keys of the keyboard are: A, S, D, F (left hand) J, K, L, (right hand) Space (thumbs of both hands). How to practice typing:
1, each finger of typing has a correct division of labor;
2, practice more in daily computer work. Put your fingers on these reference keys and divide the labor to type, which can improve typing speed.
Introduction to computers for beginners, typed manuscripts, typed manuscripts, no specific manuscript is needed, just an article is enough. With long-term training and typing practice, you will become a master of computer typing over time.
1. Understand the startup and shutdown operations.
Start up: Press the power button of the computer host to turn on the computer.
Shut down: Click the "Start" menu on the desktop, find the "Shutdown" function in "Power" and click it to shut down.
2. Understand mouse operations.
The mouse has two left and right buttons: one left-click to select the target, and two quick clicks to open the application. Right-click to open the application's function menu.
3. Learn pinyin typing.
Click on the text input box on the interface and type in pinyin by tapping on the keyboard.
Learn to use search engines.
4. Open the browser and enter what we want to find in the search box to achieve self-study of all knowledge.
The first thing is to become proficient in using the mouse. Practice dragging, copying, pasting, moving, etc. Then I started learning to type letters, pinyin, and Chinese characters on the keyboard.
Then you need to learn how to write articles, draw tables, make graphs, make slides, etc. in office software.
We often use computers in our daily lives. When we use computers, they are very helpful to our work and life, and in daily life, we can also use this Computers are used for some entertainment activities, such as watching TV, playing games, etc. So what basic knowledge do people who are just starting to learn computers need to master? Let’s take a look.
1. First of all, we need to understand some basic components of this computer. There are several basic components of the computer. One is the chassis. There are many important parts in the chassis. It can be said to be the core of the computer.
2. Then, there is the monitor, which can be used to show some pictures of the computer, just like a TV. We can use it to see some pictures, and then perform normal operations like this, We all did it while looking at the monitor.
3.再来的就是这个键盘，键盘上有很多的这个按键，我们那平时打字啊，还有一些基本的操作呢，都是靠这个键盘上的按键进行的，所以键盘一般打字都是用它来着。
4.然后呢，就是鼠标鼠标上分左键和右键还有一个，右键是用来点击这个进入页面，左键是菜单可以用来编辑，滚动的那个圈滚动轮儿可以用来这个不拿一下页面上下，当然了，如果是笔记本电脑的话就是一体的了。
5.这些呢，都是电脑的外在组件，还有呢，就是电脑的主要配件就是它的核心的一些这个组成，一个电脑的好坏，就要看他的这个内在的配件的搭配了，不管从这个什么方面来说，这个配置都是比较重要的。
6.我们可以在这个属性里边看他的这个配件这个配置，这个配置这里边最主要的是CPU，因为他呢，是这个电脑的大脑主要的控制电脑的一系列操作，目前呢，最好的CPU就算是英特尔的，然后像这个显卡呀，这个内存，硬盘呀，这些的一些配件，我们可以选择好一点儿的，如果你想要玩儿好一点儿的游戏的话，就得搭配一下，如果是平时的上上网浏览一下页面儿的话，基本上一般的都可以带的动。
