What is a granite surface table.

A surface plate is a solid flat plate used as the main horizontal reference plane for precision inspection marking out and tooling setup. There are two types of granite commonly favored in surface plate construction. Their high degree of flatness overall quality and workmanship also make them ideal bases for mounting sophisticated mechanical electronic and optical gauging systems. Surface plates come in grades of a aa b and ht200 for different applications.

The surface plate is often used as the baseline for all measurements to a workpiece therefore one primary surface is finished extremely flat with tolerances below 11 5 μm or 0 0115 mm per 2960 mm for a grade 0 plate. 3 08 g cm3 hardness. The following are the representative properties of our granites. Pink granite this type of granite is more durable due to the amount of quartz in the stone.

Use grade aa laboratory plates for precision operations in constant temperature gaging rooms and metrology departments. Metallic objects like manufactured components jobs can easily slide on their surface. A granite surface plate is an essential investment for laboratories and test facilities. Surface plates are a common tool in the manufacturing industry and are often fitted with mounting points so that it can be an integrated.

Granite as a material is superb for the production of surface tables. Surface plates can be made from a variety of materials including cast iron glass steel and granite. For reliable and consistent measurement results a granite surface plate is crucial. Excellent wear resistance low coefficient of expansion and great load bearing characteristics are all amongst the great benefits.

Granite surface plate have more rigidity for the same depth with the absence of corrosion. The ability to hand lap the table at site if and when it becomes necessary makes the service support of the product an excellent economic choice.

In such granite the minerals are evenly distributed resulting in a homogenous appearance. They provide a high modulus of rigidity and are moisture free. Surface plates standridge granite surface plates provide an accurate reference plane for work inspection and for work layout. During world war ii when metal was necessary for military production using granite for surface plates came into common use.

Solid granite surface plate and angle plates are used for precision layout inspection and tooling setup. The stands provide a working height of 34 0 86m with five adjustable points for levelling. Cast iron surface plate is 2285 iso 8512 1 glass plate is 14900 granite surface plate. A surface plate of 600 x 600 mm can be mounted on a support stand.
