What Is a Stone Surface Plate?
A stone surface plate is a platform used as a reference plane for precise dimensional measurement and inspection of materials and parts in processing. These plates are typically rectangular and come in various sizes to suit different objects.
They must possess high flatness accuracy and rigidity, to maintain precision even under heavy loads. Both accuracy and size standards are defined by JIS, which also allows for customization like holes and ribs for part fixation.
While JIS specifies both cast iron and stone as materials, the standards for each are quite similar.
Uses of Stone Surface Plate
Stone surface plates ensure a flat surface for activities like marking, machining, or measuring. They provide a reference plane, enabling precise machining and measurement. Their primary attributes include wear resistance and resistance to environmental factors.
Principle of Stone Surface Plate
As a benchmark for flatness (graded according to JIS B 7513), these plates must be rigid to avoid deformation under heavy loads, affecting measurement accuracy. Handling precautions include installation in a controlled environment, away from direct sunlight and sudden air currents.
Characteristics of Stone Surface Plate
Stone surface plates, compared to cast iron, exhibit less aging, higher abrasion and environmental resistance, and are non-magnetic. They require periodic polishing to maintain flatness. Their low aging and high wear resistance extend the time between regrindings, reducing maintenance costs.
Additionally, these plates resist damage from accidental impacts, safeguarding both the plate and equipment. Despite their advantages, the main drawback is the higher cost, attributed to the harder material and longer processing time required for flattening.
Other Information on Stone Surface Plate
1. Grades of Stone Surface Plate
JIS classifies these plates into grades 0, 1, and 2, with grade 0 being the most precise. Flatness tolerance is calculated using constants C1, C2, and the plate's diagonal length. The cost varies by grade, necessitating selection based on required flatness and size.
2. Care of Stone Surface Plate
Maintenance is crucial for ensuring ongoing accuracy. Regular cleaning prevents surface deterioration and measurement errors. Special cleaners are used, followed by wiping with water and drying with a cloth. Regular flatness checks and protective covering after use are also important.
With proper care, stone surface plates can last semi-permanently without significant changes over time.
