How to inspect the accuracy of a marble and granite right angle ruler
When inspecting the verticality of some workshop equipment and mechanical devices, a Marble and Granite right-angle ruler is required. The use of a Marble and Granite right-angle ruler can help further determine the stability and accuracy of these mechanical devices, so that various components can be manufactured more accurately during operation, facilitating workers' operation of mechanical equipment. Below is an introduction to how to inspect the accuracy of a Marble and Granite right-angle ruler.
I. Product Introduction of Marble and Granite Right-Angle Ruler
- The main mineral components of the granite angle ruler are feldspar, plagioclase, a small amount of olivine, biotite, and trace magnetite, with a black color and a precise structural code. After hundreds of millions of years of aging, it has a uniform texture, good stability, high strength, and high hardness, and can maintain high precision under heavy loads. The Marble and Granite right-angle ruler is suitable for measurement work in industrial production and laboratories.
- A Marble and Granite right-angle ruler is a professional measuring tool, simply called an angle ruler, and is also known as a straightedge in some occasions. It is used to detect the verticality of workpieces and the verticality of the relative positions of workpieces, and is sometimes used for marking.
II. What is a Marble and Granite Right-Angle Ruler?
The main mineral components of the Marble and Granite right-angle ruler are feldspar, plagioclase, a small amount of olivine, biotite, and trace magnetite, with a black color and a precise structural code. After hundreds of millions of years of aging, it has a uniform texture, good stability, high strength, and high hardness, and can maintain high precision under heavy loads. The Marble and Granite right-angle ruler is suitable for measurement work in industrial production and laboratories, and can also be used for detection, measurement, marking, equipment installation, and industrial engineering construction. As a professional measuring tool, it is simply called an angle ruler or a straightedge in some occasions. It is used to detect the verticality of workpieces and the verticality of the relative positions of workpiece materials, and is sometimes used for marking.
After long-term natural aging, the organizational structure is uniform, the linear expansion coefficient is extremely small, the internal stress is completely eliminated, and it does not deform, so it has high accuracy. It is not afraid of erosion by acid and alkali liquids, does not rust, does not need to be oiled, is not easy to stick to dust, and is convenient and simple to maintain. The straightness standard of the Marble and Granite right-angle ruler is GB6092-85, and the verticality standard is GB6092-85. Weight reduction holes are added to reduce weight and facilitate processing. The tolerance of the side is 0.02. It is suitable for the verticality inspection of machine tools, mechanical equipment, and components, installation and processing positioning, marking, etc., and is an important measuring tool in the mechanical industry. It is characterized by high accuracy, good stability, and convenient maintenance.
III. How to Inspect the Accuracy of a Marble and Granite Right-Angle Ruler?
- When inspecting the accuracy of the Marble and Granite right-angle ruler, first fix the Marble and Granite right-angle ruler stably on the Marble and Granite plate to keep its working surface horizontal. Select an appropriate detection bridge plate according to the length of the right-angle ruler's working surface (generally 8-10 steps, with a span of 50-500mm); then place the bridge plate at one end of the Marble and Granite right-angle ruler and fix the level on the bridge plate.
- Move the bridge plate gradually from one end of the right-angle ruler to the other end according to the span. For each span moved, read the value at that position from an electronic level with a graduation value of 0.001mm/m. The difference between the maximum and minimum values is the straightness error of the working surface of the Marble and Granite right-angle ruler. The straightness error of any 200mm of the working surface can be inspected and determined by selecting a bridge plate of 50mm or 100mm and following the above method within any 200mm.
- When inspecting the verticality of the two working surfaces of the Marble and Granite right-angle ruler, first place the straightedge on the precision Marble and Granite plate, and zero the dial indicator seat with a dial indicator of 0.001mm graduation value through a standard round bar on the standard Marble and Granite square box. Then, in the same way, make the dial indicator seat lean against the other working surface of the Marble and Granite right-angle ruler. At this time, the reading of the dial indicator is the verticality error of the side. The verticality of the Marble and Granite right-angle ruler is taken as the maximum error value.
When inspecting the accuracy of the Marble and Granite right-angle ruler, it is necessary to grasp every step. Whether it is the fixing of the Marble and Granite right-angle ruler or the calibration of the Marble and Granite right-angle ruler, it requires a comprehensive understanding of the Marble and Granite right-angle ruler, so that the actual operation can be more efficient and accurate. The application of the Marble and Granite right-angle ruler is quite extensive.
