• Additional height adjustment on the internal grinding slide by approx. 150 mm
• Digital display of grinding wheel speeds
• Grinding wheel dressing devices mounted on the grinding column, or can be manually swung in
• Separate hydraulic unit * Separate control cabinet *
• Magnetic face plate with infinitely variable holding force adjustment, various small parts
