Granite Surface Plate
Granite surface plate
Granite Surface Plate is widely used in basic metrology. It is used as the Zero face for height measurements, flatness measurements, …
Introduction
The MAP table, also known as the Standard Check Table, is a device commonly used for the work of checking the coplanarity in measurement, checking the standard surface with high accuracies such as altimeter, flatness measurement, and other tests other.
The MAP table has a very high flatness, with roughness from a few micros to a few tens of micrometers, so it is considered a standard plane to check the product’s coplanarity.
Common applications in factories, factories, workshops, or laboratories, …
In addition, the MAP table made from Granite also possesses the following advantages:
- Granite size is almost unchanged when the temperature changes
- Less damage to the measuring materials placed on the table
- Natural Granite is extremely safe to use, no difficulty working with magnetic materials.
Types of Granite Surface Plate
MAP table with material from Granite
- Granite has a very high carbon content that is mined from nature in Granite quarries
- High plane accuracy
- High wear resistance
- Good durability
- No distortion over time
Dimensions produced according to customer requirements:
2000 x 500 x 250 mm

MAP table with material from cast iron
- Cast from solid cast iron
- The surface is smoothed to the required roughness
- Then take it to surface treatment
- Mainly used with magnetic test instruments so that it can be fastened to the tabletop
