Granite surface plate is a natural stone material made of precision reference measurement tools, for the instrumentation, precision tools, mechanical castings inspection, are the ideal datum.
Granite is considered the best material for surface plates because its properties (e.g., surface hardness, low thermal expansion, no rust or corrosion, little warping, longer wear life) result in very accurate, stable, and precise surfaces
Of them, carbon steel is the widely used material for making a welding table. Carbon steel is an alloy of iron and carbon. Next, the best option is a Stainless Steel welding table. It has chromium content which provides corrosion resistance to the table.
A cast production table is made primarily of cast iron or other similar durable materials. These tables are often engineered for high-precision industrial applications, making them a tempting option for welders
Granite is a superior material for surface plates because it is durable, precise, and low maintenance. Granite is resistant to rust and corrosion, and it's almost impossible for it to warp.
These slots allow for secure fastening of workpieces using nuts and bolts, and clamping bolts can be affixed within the slots on the top surface. The bottom side can be securely attached to the machine table, serving to fasten, support, and facilitate workpiece marking and machining.
