Mille-Pin is often used in the work. Along the rotation axis or a back of a snail distance.
Consequently, a small distance that moves along the direction of the axis can be represented by reading numbers over the circular period. So, how does he do such a specific instrument, what do you know about his use skills?
Today, I will give you a summary of knowledge!
First of all, let’s take a look at the most common countryside thousands of feet.

The names of each piece and the name of the main components are illustrated in the figure below:
尺 The principle of the principle of measurement of the standard machine
The distance from the heart shaft runs P (p = 0.5 mm) and is divided into 50 divisions (scale) to be divided into 50, in order to obtain the number of reading from 1 scale to 0.01 mm.

The basic structure is represented in the figure below.

The resolution is 0.001 mm and the distance from the heart shaft is divided into 500 points through the sensor (rotor, stator), 0.5 mm ÷ 500 = 0.001 mm.
The principle of measuring thousands of feet
In addition to the two thousand meters current above, there is also one of the outside diameter of the next countdown account.
Thousands of feet measurement devices
The system for measuring the force of a thousand meters is also one of the most important components.
Note: This graph comes from the introduction of the measuring device to three thousand thousand.
Precautions for the use of a thousand meter products
Now that the basic structure and the method of reading thousands of feet are introduced, the more Xiaobian WeChat yuki7557 obtains tutorials 10g CNC, the most important thing is the precautions and maintenance and maintenance of thousands of feet when the ‘Use of a thousand feet products.
1. Carefully check the type, measurement range, precision and other specifications and select the appropriate model for your goal.
2. Before the measurement, the thousand feet and the parts are placed at room temperature for a long time to balance the temperature.
3. Read the reference line when you read the micro-division cylinder. If you look at the ladder line from a certain angle, the correct position of the line will not be read because the visual error will be read.
4. Adjust the starting point (zero) before the measurement and use the paper which cannot afford the hair to wipe the measurement surface of the IVillery and the microphone screw.
5. As part of daily maintenance, wipe out any dust, debris and other fragments around the environment and the measurement surface. In addition, wipe the stains and fingerprints with a dry cloth.
6. Use the measurement force device correctly to measure under the correct measurement force.
7. When installing a thousand feet in a tablet with a thousand feet, the tables must be fixed at the center of the thousand points frame. But don’t pinch too much.
8. Be careful not to fall or collide with thousands of feet. Do not over-protect the microcotial screw with thousands of feet. If the accidental accidental operation leads to damage the thousand feet, check its precision more before use.
9. After storage for a long time or a movie of protective oil, gently wipe thousands of feet in soaked fabric in corrosive oil.
10. Precautions: Avoid direct sunlight during storage. Store in places with good ventilation and low humidity. Add Xiaobian WeChat Yuki7557 to obtain a CNC 10G tutorial and store in a dustless place. If it is stored in a box or other container, the box or the container cannot be placed on the ground. During storage, there should be a space between 0.1 mm and 1 mm between the measurement surfaces. Do not store a thousand feet in a tightening state.
Maintenance of the use of the product thousand movies
First of all: carefully wipe the dirt and the fingerprints stained in all the parts.
If it is kept and dried for a long time, wipe the thin layer of oil with a cloth with anti-grinding oil, do it, do it, this will guarantee that your thousand feet performance is durable.
Finally, when the storage of thousands of feet, you should pay attention to the following points.
1. Pay attention to storage in full sun, less humidity, good ventilation and less dust.
2. Do not forget to store it in the storage box, do not place it directly on the ground.
3. The most important point: open about 0.1 to 1 mm between the two measurement plans and do not locate the device closely to prevent failure during the storage process.
Daguang focuses on providing solutions such as precision CNC machining services (3-axis, 4-axis, 5-axis machining), CNC milling, 3D printing and rapid prototyping services.
