1 point The selected point is to map the design of the point of implementation to the field, and modify according to the specific circumstances. Select the corner network in good visibility, accessibility, foundation stability and long-term preservation of the place. Sight to avoid obstacles. For long-term preservation, far away from the construction area to take into account the graphics structure and easy to encrypt. The control points that are directly used for construction lofting should be convenient for setting out. 2 build a standard 1 Buried ground standard stone is a well-embedded embedded metal center mark standard stone pouring buried in the ground, the process is: dig foundation pit bottom of the pit to be flat compaction, and then filled with sand tamping, pouring the bottom of the concrete tree Stone and pouring concrete. 2 on the rock or hard concrete road surface, you can direct drilling, engraved with the center of the anchor bolt bolted into the hole. 3 standard stone buried to stabilize at least 15 days to start the observation.
SGI provides 5 axis machining services that achieve an angular tolerance of +/- 0.005mm. We specialize in true 5 axis machining, manufacturing 5-axis machining components with ease. It takes more than just excellent machining and programming skills to preform true 5 axis work. With 5 axis machining, complex parts that may have to be milled from a solid piece of material. For prototypes and short runs, this is quicker and cheaper. Micro drilling applications that require many holes with different angles are performed more efficiently on a 5 axis machine.
