Cast iron surface plate is 2285 iso 8512 1 glass plate is 14900 granite surface plate.

What is a granite surface table.

Surface plates standridge granite surface plates provide an accurate reference plane for work inspection and for work layout. 3 08 g cm3 hardness. Surface plates can be made from a variety of materials including cast iron glass steel and granite. During world war ii when metal was necessary for military production using granite for surface plates came into common use.

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. Solid granite surface plate and angle plates are used for precision layout inspection and tooling setup. Fine specific gravity. Granite as a material is superb for the production of surface tables.

Metallic objects like manufactured components jobs can easily slide on their surface. Their high degree of flatness overall quality and workmanship also make them ideal bases for mounting sophisticated mechanical electronic and optical gauging systems. The stands provide a working height of 34 0 86m with five adjustable points for levelling. 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. Why are certain types of granite used in surface plates. Surface plates come in grades of a aa b and ht200 for different applications. Excellent wear resistance low coefficient of expansion and great load bearing characteristics are all amongst the great benefits.

Use grade aa laboratory plates for precision operations in constant temperature gaging rooms and metrology departments. A surface plate is a solid flat plate used as the main horizontal reference plane for precision inspection marking out and tooling setup. Mhc 641 0047 granite surface table 1200 x 800 x 150mm grade 1 accuracy to din 876 stand not included in price. For reliable and consistent measurement results a granite surface plate is crucial.

Pink granite this type of granite is more durable due to the amount of quartz in the stone. The following are the representative properties of our granites. A surface plate of 600 x 600 mm can be mounted on a support stand. There are two types of granite commonly favored in surface plate construction.

They provide a high modulus of rigidity and are moisture free. Mhc 64s 1020 stand for granite plate 24 x 36. Mhc 642 0025 granite surface plate 630 x 630 x 130mm grade 1 granite plate to din876. Granite surface plates are made from select granite with uniform distribution of light and dark constituents.
