The cast iron coordinate alignment surface plate provides a precise reference plane for measurement and various inspection applications. It is used to verify the dimensional accuracy of mechanical components and has become an essential tool in the machinery manufacturing industry.

Size
Standard measuring plates are available in sizes ranging from 100mm × 100mm to 2000mm × 4000mm. Custom sizes can also be produced based on customer drawings or mutual consultation.

Precision
Our surface plates are manufactured in compliance with national metrological verification standards, and are available in four accuracy grades: Grade 0, Grade 1, Grade 2, and Grade 3.

• Grade 0 & Grade 1: Minimum of 25 support points per 25mm²

• Grade 2: Minimum of 20 support points per 25mm²

• Grade 3: Minimum of 12 support points per 25mm²

Materials

• High-strength cast iron HT200–300
