Marble square is mainly used for the inspection of the verticality of some workshop equipment and mechanical devices. The use of marble square can help us to further determine the stability and accuracy of these mechanical devices, so that when the operation is used, it can also be more accurately produced a variety of components to facilitate the worker's operation of the mechanical equipment. , to tell you about what is a marble square and how to check the accuracy of the marble square .
One, what is a marble square
The main minerals of the marble square are the escaping stone, plagioclase, a small amount of olivine, biotite and trace magnetite, black color, and structural precision code. After aging for hundreds of millions of years, the texture is uniform, the stability is good, and the strength is high. High hardness, can maintain high precision under heavy load. Marble squares are suitable for industrial production and laboratory measurements. They can also be used for inspection, measurement, marking, equipment installation, and industrial engineering. Is a professional measuring tool, referred to as a square, also known as the ruler in some occasions, is used to detect the verticality of the workpiece and the verticality of the workpiece relative to the material position, and sometimes also used for marking.
After long-term natural aging, uniform structure, linear expansion coefficient is very small, internal stress completely disappears, no deformation, so high precision, not afraid of acid, helium liquid material erosion, will not rust, do not have oil, not sticky dust, maintenance Convenient and easy to maintain, the straightness standard of marble square ruler GB6092-85, vertical standard GB6092-85. Weight reduction holes are added to reduce weight and facilitate processing. The lateral tolerance is 0.02. Applicable to vertical inspection of machine tools, mechanical equipment and parts, installation and processing positioning, marking, etc. are important measuring tools in the mechanical industry. Its features are high precision, good stability and easy maintenance.
Marble Square - Product Application
1. The marble square is suitable for the detection of verticality. The plane accuracy standard GB6092-85, the vertical standard GB6092-85. Weight reduction holes are added to reduce weight and facilitate processing. The lateral tolerance is 0.02.
2. The marble square is used for testing, measuring, marking, equipment installation and industrial engineering. It is a kind of professional measuring tool and is called square for short. It is also called the ruler in some occasions. It is used to detect the verticality and workpiece of the workpiece. The perpendicularity of the relative position is also sometimes used for scribing.
3, marble square is suitable for vertical inspection of machine tools, mechanical equipment and parts, installation and processing positioning, marking, etc. are important measurement tools in the machinery industry, its characteristics are high precision, good stability, easy maintenance.
4. The main minerals of marble squares are pyroxene, plagioclase, a small amount of olivine, biotite and trace magnetite, black color, precise structure, aging after hundreds of millions of years, uniform texture, good stability, and high strength. , high hardness, can maintain high precision under heavy load. Suitable for industrial production and laboratory measurements.
Marble Square - Product Features
1. The rock has long-term natural aging, uniform organization structure, minimal linear expansion coefficient, internal stress completely disappeared, no deformation, and therefore high precision.
2, good rigidity, high hardness, strong wear resistance.
3, not afraid of acid, liquid material erosion, will not rust, do not have to oil, easy to stick dust, maintenance, easy maintenance, long service life.
4, no scratches, not subject to constant temperature conditions, at room temperature can also maintain the accuracy of temperature measurement.
5, no magnetization, smooth movement can be measured, no sense of stagnation, not affected by the humidity, the plane is set well.
Marble Square - Note
Often due to improper use caused by premature damage or accuracy error, so we must pay attention to the correct use of the marble square, to extend the life of marble flat feet. When using a marble square, hold it lightly and put it gently. When testing the workpiece, force the square of the marble against the measuring surface of the workpiece. The marble square is generally used in a constant temperature room. After use, wipe it with a soft cloth and apply a special layer of oil to the box.

Marble square material
The main minerals are pyroxene, plagioclase, a small amount of olivine, biotite and trace magnetite, black color, precise structure, aging after hundreds of millions of years, uniform texture, good stability, high strength, high hardness, energy Maintain high accuracy under heavy loads. Suitable for industrial production and laboratory measurements.
Second, how to check the marble square
1. When verifying the accuracy of the marble square, firstly fix the marble square firmly on the marble plate to keep the working surface horizontal, and select the appropriate bridge according to the length of the square (usually according to 8~ 10 steps, span between 50 and 500mm); then place the bridge on one end of the marble square to fix the level on the bridge.
2. The bridge plate is gradually moved from one end of the square to the other along the span, and the difference between the maximum value and the minimum value of the position reading is read from an electronic level with a graduation of 0.001 mm/m. It is the straightness error of the marble square ruler face. Any 200mm straightness error on the working surface, choose 50mm or 100mm bridge, according to the above method in any 200mm inspection and determination.
3. When verifying the squareness of the two working faces of the marble square, place the flat rule on the precision marble plate first, and then use the standard round bar on the table with the graduation index of 0.001mm, on the standard marble square box. To zero. Then, in the same way, the table seat is held against the other face of the marble square, and the reading of the dial gauge is the verticality error of the side. The squareness of the marble square is taken as the maximum error.
The inspection of the accuracy of marble square should pay attention to every step. Whether it is for the fixing of marble squares or the calibration of marble squares, we need a more comprehensive understanding of marble squares. This will be more rapid and accurate in the actual operation process, the use of marble square is more extensive.
Editor's summary: The relevant information about what is a marble square and how to test the marble square is introduced here. I hope this article will help everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.
