for valve seatsverticalconventional

Description
Serdi srl - Italy. EVO PLUS is a valve seat and valve guide machine with an automatic centering system based on crossed spherical and flat air-float cushions. Electronic motor control with variable speed and digital counter (inverter). High-speed silenced spindle bearings. Designed for machining multi-valve aluminium cylinder heads with a maximum distance of 600 mm between the first and last guide valve. Allows guide machining from 3.5 mm and seat diameters from 14 - 60 mm. Modular steel bed and lower table on air cushion with high-capacity vacuum clamping. Lower table with "no limit" travel 600 x 200 mm. Two air cushions: spindle spherical 360° and lower clamping fixture 2-axis. Universal tilting clamping fixture with accessories for various cylinder head types. Integrated lighting with two lamps on the workhead.
