Precautions in designing marble mechanical components

New details

The working surface of marble mechanical components is easy to maintain in use, and the material is stable, which can be determined that it will not deform for a long time. Marble mechanical components can slide smoothly without stagnation in measurement. The measurement of the working face is accurate, and the general scratch does not affect the measurement accuracy

there are many matters needing attention in the design of marble mechanical components. Let me introduce them to you in detail:

I. bearing capacity and load properties

II. Whether screws are needed on the straight rail and whether grooves can be used instead

III. surface roughness and flatness

IV. whether the foundation parts are supported by steel frame or vibration isolation system

v. whether the side of granite is visible

VI. whether there is air bearing surface

VII. Temperature change, humidity, vibration, dust, etc. of the use environment

VIII. Insert size, hole position accuracy and insert transmission torque

in the past, marble mechanical component products were mainly used in mechanical manufacturing industry. It mainly existed as an instrument and measuring tool. Therefore, for a long time, its market demand has remained within a specific range without great expansion. However, in recent years, due to the improvement of people's living standards, marble mechanical components have been widely used in people's family life. Marble mechanical component products are a symbol of quality and taste, especially in line with the aesthetics of modern people. Therefore, this is also the reason for the development of the domestic market of marble mechanical component products in recent years. Marble mechanical components are suitable for the on-site working environment, and are highly permanent. They maintain the accuracy characteristics of the product itself for a long time. The more they can determine the accuracy of processing and testing in the working environment and the quality of working products, especially for measurement. The specific advantages of marble mechanical components are as follows:

first, the granite platform has dense organizational structure, smooth surface and small roughness value

II. After long-term natural aging, the internal stress of granite disappears completely, the material is stable and will not deform

III. it will not be affected by moisture and rust, and it is convenient to use and maintain

IV. small linear expansion coefficient and little influence by temperature

v. after the working face is collided or scratched, it will only produce pits, no convex lines and burrs, and have no impact on the measurement accuracy

VI. the greater the thermal stress, the easier it is to produce cracks than arc welding, and the greater the tendency of linear shrinkage to produce cracks. As the crack tendency is affected by factors such as spray welding time and spray layer thickness, the size of defects is limited accordingly, and the defects repaired by welding need to be cleaned up. Due to the good proportion of Fe content in spray powder

VII. The color of the formed spray layer is closer to that of the base metal than that of arc welding. However, due to the corresponding amount of Ni, it cannot be closer to the color of the base metal, and machining can be carried out after welding repair. The conservative spray welding and arc welding process is easy to produce cracks after welding repair, and the workpiece is easy to be heated and deformed

based on the original granite platform, marble mechanical components are drilled, grooved, found parallelism and flatness according to the actual needs of customers. The overall technical requirements are much stricter than ordinary granite platforms. Marble mechanical components are mostly used for tooling in the machinery industry, so they are called marble mechanical components or granite components. Abrasion resistance, high temperature, physical stability, meticulous organization, the impact grains fall off, and the surface does not have burrs, which does not affect the plane accuracy of the granite measuring plate. The working surface is easy to maintain in use, with stable material, small linear expansion coefficient, good mechanical accuracy, no deformation, good hardness and strong durability. It is suitable for the on-site working environment. It can slide smoothly without stagnation during measurement. The measurement of the working face is accurate, and the general scratch does not affect the measurement accuracy. Granite components are made of stone and have the characteristics of no rust and good service life
