• Built for automatic loading on ANCA, Walter Helitronic, Saacke, Schütte and Vollmer CNC grinders.
• Repeatable concentricity ≤ 0.005 mm (5 µm), fine runout alignment down to 1 µm, and 9.6 kN clamping force.
• Through-jaw coolant along tool flutes and active sealing air protection against carbide grinding sludge.
