Detailed Product Description: | Design and technical requirements granite slab design requirements are generally based on "The People's Republic of China Machinery Industry Standard" JB / T 7974-2000 Design. Also need to specify the actual granite slab design and production of technical requirements. National standards in the granite slab, granite slab corporate standards and requirements for use, it is possible according to the actual demand for granite slab design and production technology request. Design and production of granite slab must be based on the lowest cost to make the best product for the principle. Granite slab in the production process, will produce some errors in the theoretical weight, it should be noted that the production of flat granite effect error is the normal use of flat granite. General granite slab should be designed to take into account the error of machining and casting errors, granite slab weight error is generally not more than 10%, more than 10%, we want to re-do the quality granite slab further identification and testing to determine the granite slab is not possible to properly put into use. Granite slab during the production processes may be some defects in the product, as long as the correct way to make up for process maintenance. The following is a granite tablet into production in the Technical Notes: ⒈ flat granite work surface may not have seriously affect the appearance and performance of the sand holes, shrinkage, scratches, bumps, holes, cracks, slag rust, etc. defects. ⒉ granite slab non-working surface depressions or off angle to allow repair. ⒊ granite slab on the side face of the vertical tolerance and tablet two adjacent sides of the vertical tolerances specified according GB/T1184 12. ⒋ granite slab face the central area of ??concentrated load, the applied load and allowable deflection values ??in Table 3 requirements. ⒌ 000-level and 00 flat panel does not recommend setting the carrying handle. ⒍ if 0 and a flat surface of threaded holes (or grooves), the site should not be higher than face. ⒎ granite slab should be fine grain, dense structure gabbro, diabase and granite (biotite should be less than 5%, modulus of elasticity should be greater than 0.6 × 10-4kg/cm2, water absorption should be less than 0.25%) and other materials, and its face hardness should be greater than 70HS. ⒏ granite slab surface roughness Ra face the maximum allowable value of 0.32 ~ 0.63um, the side of 10um. ⒐ granite slab face flatness tolerance ⒑ right diagonal method or the grid method using flat working surface flatness inspection, should examine the amount of air plane fluctuations, fluctuations in the amount of face plane |
