Why the Technology is the best in the market?The dual air-float automatic SERDI centering system was the first in the world made with the patented process Why the SERDI Technology is the best in the market?The dual air-float automatic centering system was the first in the world made with the patented process developed by the SERDI Company. This unique method uses a solid carbide straight shank pilot. When inserted into the valve guide, it simulates the real valve stem during the centering process. This guaranteed the valve seat is finished within the closest tolerance for a perfect valve to seat match. The new design SERDI workhead greatly reduces the number of parts free-floating during the centering sequence. The built-in spindle motor eliminates all pulleys, belts and transmission shafts. This results in minimal workhead inertia and maximum flotation for unmatched sensitivity and accuracy during the centering process. From Import & Domestic Engines, to High Performance Racing Engines, to Motorcycle Engines, to Marine Engines, to Trucks Public Transport Engines, to Locomotive Engines, to Small Engines, to Stationary Engines, SERDI is the one!SERDI is the Worldwide Leader.
