SERIES 311

• The High Precision Square is a gage used for inspecting the travel straightness and axial perpendicularity of moving elements on equipment such as machine tools, CMMs, form measuring machines and semiconductor-related equipment
• For precision-lapped reference surface are provided
• Better than 1μm/300mm straightness and perpendicularity of each (four) reference surface. In addition, front and back faces are accurate to better than 5μm/300mm
