Wrap-resistant Abrasive Resistant Granite Surface Plate
Granite surface plate the hardness and stability allow accuracies within millionths of an inch. Along with the high accuracies, granite surface plate is rust-proof, non-magnetic, abrasive resistant, non wedging, wrap-resistant and easily cleaned. The granite used for surface plates has an excellent distribution of hard quartz which provides a smooth, long-wearing working surface.
Granite surface plates meet or exceed Federal Specifications DIN/876. Final inspection and calibration of every surface plate is accomplished by use of the Auto-Collimeter
granite surface plate's The standard sizes, absolute flatness tolerances (in thousandths of mm) and reference codes are present in the table on the catalogue. We can supply as per the needs of the customer, glued threaded inserts, as per drawing with holes, clearing grooves, T-slots and with rubber feet for smaller sizes.
Our granite surface plate refers to the advanced standards of the leading countries, and its flatness tolerance is in accordance with the JB/T 7975-1999 Surface Plate:
Grade 000 =1x(1+d/1000)/μm
Grade 00 =2x(1+d/1000)/μm
Grade 0 =4x(1+d/1000)/μm
Grade 1 =8x(1+d/1000)/μm
(d is the length of the diagonal)
