1200 x 800 mm Black Flat Granite Lapping Plate

High precision granite surface plates can provide an accurate reference plane for work inspection and for work layout. The high degree of flatness, quality and workmanship also make them ideal bases for mounting sophisticated mechanical, electronic and optical gauging systems.

 
feature

1. Alkali and acid resistant, smooth surface
2. No ridges, burrs,
3. Wear resistance, anti-magnetization

Repeatability:

• Grade "B" Toolroom ± 100 Millionths
• Grade "A" Inspection ± 50 Millionths

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)
