Serdi 4.5 Power

Key Features

• Triple Air-Cushion Centering System — This patented system uses three air-float stages (including a spherical-cushion “live pilot”) so the machine automatically aligns to each valve guide, even if the guide or head is slightly misaligned or angled — delivering excellent concentricity and seat alignment.
• Wide Seat Diameter Capacity: 16 mm – 120 mm (0.6″ – 4.72″) — Compatible with small automotive valve seats up to large industrial or diesel engine valves — offering broad versatility.
• Powerful 2.2 kW Built-In Spindle Motor — Provides the torque and stability needed for cutting both small and large valve seats, including hardened seats and heavy-duty applications.
• Smooth Variable Spindle Speed (80–840 rpm) — Allows precise control over cutting speed for different seat profiles or materials.
• Heavy-Duty Cast-Iron Construction & Rigid Frame — Provides stability and minimal vibration even when machining large heads or performing heavy seat cuts.
• Large Table & Clamping Capacity — Air-floated table supports heavy and large cylinder heads; clamping system accommodates vertical or inclined valve-guide heads — suitable for automotive, diesel, marine, stationary-engine, and industrial heads.
• Digital Depth Control (0.01 mm / 0.0004″ resolution) — Ensures precise seat depth control and consistency across multiple valves or heads.
• Optional Vacuum Tester and Seat-Seal Check — Some configurations allow checking valve seat sealing before removing the head — useful for heavy-duty or performance work where sealing integrity is critical.
