The carving machine base produced by Botou Maixin Machinery Casting Co., Ltd. is a precision reference measuring tool made of stone material. It is an ideal reference surface for the inspection of instruments, precision tools, and mechanical parts, especially for high-precision measurement. Granite is made from underground rock layers and has undergone billions of years of natural aging, resulting in an extremely stable shape without worrying about deformation due to conventional temperature differences. The granite material selected through rigorous physical testing is finely crystallized and has a hard texture. Due to the non-metallic nature of granite, it exhibits magnetic reactivity.

The carving machine base produced by Botou Maixin Machinery Casting Co., Ltd. also has no plastic deformation. Its hardness is high, therefore it has good accuracy retention. Even if rock tools are hit by heavy objects during use, at most a few pieces of gravel will fall off. It is superior to precision measurement reference parts made of cast iron and steel, and can achieve high and stable accuracy. The 1000 × 630mm '00' grade granite slab produced by our factory can still maintain its original accuracy after being stored for one year.

The characteristics and advantages of the carving machine base produced by Botou Maixin Machinery Casting Co., Ltd.:

1、 The base rock of the precision carving machine has undergone long-term aging, with uniform organizational structure, linear expansion coefficient, disappearance of internal stress, and no deformation, resulting in high accuracy.

2、 Good rigidity, high hardness, and strength.

3、 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.

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

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