Granite lined flat plate

Introduction to Granite Marking Plank: Marble slabs and platforms are made from underground rock layers. After billions of years of natural aging, their shape is extremely stable, and there is no need to worry about deformation due to conventional temperature differences. After rigorous physical testing and selection, the granite material has fine crystallization, hard texture, compressive strength, and a hardness of 6-7 Mohs hardness. Extremely acid and alkali resistant, with high resistance and will not rust. Due to its non-metallic nature, marble exhibits magnetic reactivity and does not undergo plastic deformation. Its hardness is 2-3 times higher than cast iron (equivalent to HRC& gt;51)， Therefore, the accuracy retention is good. Even if rock tools are hit by heavy objects during use, they will only drop a few pieces of gravel at most, and will not damage accuracy due to deformation like metal tools. It is superior to measuring reference parts made of cast iron and steel, and can achieve high and stable accuracy.

Characteristics and advantages of granite marking flat plate

After long-term aging, the rock has a uniform organizational structure, low coefficient of linear expansion, disappearance of internal stress, and no deformation, therefore.

Good rigidity,.

Not afraid of acid and alkali erosion, will not rust, does not need to be oiled, is not easy to stick to dust, easy to maintain, and has a long service life.

No scratches, not hindered by constant temperature conditions, and able to maintain temperature measurement accuracy at room temperature.

Non magnetized, able to move smoothly during measurement, without any sluggishness, not affected by moisture, and the plane is properly weighed.

Marble slabs are usually equipped with brackets, which are usually customized according to the specifications of the marble slab, and can be made according to customer requirements. The bracket is generally welded with square steel, and the height is determined according to the thickness of the marble slab. Generally, the height of the working surface above the ground after placing the marble slab on the bracket is designed to be 800mm.

There are five support points under the bracket that touch the ground, three of which are fixed and the other two are adjustment support points used for rough leveling. There are also five adjustable support points above the bracket that touch the marble tablet, all of which are used for fine leveling. It should be noted that the five support points that touch the tablet also need to be adjusted at three points, that is, the surface of a triangle, and the other two are used for auxiliary fine adjustment.
