Double groove ground rail, also known as double groove ground beam, double groove platform, or double groove iron. Double groove ground rail material: HT200-300，QT400-600，ZG20-45#。  The gap between the double groove ground rails (padded with wooden strips) is 5mm; The allowable deviation of non parallelism of the ground rail in the horizontal plane is 0.10/1000, with a total length of 0.5mm. The allowable deviation of unevenness in the vertical plane of each double groove ground rail is 0.10/1000, with a total length of 0.5mm.

The gap between the double groove ground rails (padded with wooden strips) is 5mm; The allowable deviation of non parallelism of the ground rail in the horizontal plane is 0.10/1000, with a total length of 0.5mm. The allowable deviation of unevenness in the vertical plane of each double groove ground rail is 0.10/1000, with a total length of 0.5mm. Double groove ground rails are used for various inspection work, such as reference planes for measurement, inspection and measurement of various machine tools and machinery, checking the dimensional accuracy and line deviation of parts, and making lines. Ground rails are products of more than 20 industries such as machine tools, mechanical manufacturing, and electronic production. The ground rail is an indispensable workbench for marking, measuring, riveting, and tooling processes, and can also be used as a mechanical testing platform, etc.

Other Description

The purpose of the ground rail is to design and assemble a casting beam platform based on the fixed points of the equipment, mainly used for the assembly, testing, welding, and inspection of large equipment. 

Advantages of ground rail: This eliminates the need for a large platform, saving material costs and occupying minimal space, making it highly cost-effective. 

The material of the ground rail is cast iron HT200-300, with a working face hardness of HB170-240. After two manual treatments (manual annealing at 600-700 degrees or natural aging for 2-3 years), the accuracy of the product is stabilized. 

Specification of ground rail: Specific specifications can be made according to the buyer's drawings or agreed upon by both parties for production and processing

Common modeling method for ground rails: sand mold. 

Ground rail molding materials: molding sand, clay sand, core sand, resin sand.
