Serdi 2.0 ES Valve Guide and Seat Cutting Machine
Machining process form tool Operating Manual Power 2.2 kW
Centering technology -Double air cushion
Valve seat capacity 28 to 120 mm / 1.1" to 4.72" Spindle speed 80 to 840 rpm
Automotive Heavy duty
Best budget machine designed on the working principle of the double air-float centering system, with a built-in motor spindle delivering powerful torque, a very high rigidity machining head and frame, being able to carry any conventional heads.
2.2 KW BUILT-IN MOTOR SPINDLE
A 2.2 KW built-in motor-spindle with maximum torque from 40 to 385 rpm and a maximum speed of 840 rpm. Stator cooled by heat sink Rigid heavy duty motorspindle of 3.15 in (80 mm) diameter for machining without chatter. Get the best machining accuracy thanks to a high precision tooth rack and a whole spindle assembly rigid and concentric to the valve guide.
DOUBLE AIR CUSHION CENTERING
The centering is made by association of a spindle floating on a spherical air cushion and a rigid light weight aluminium head plate floating on a plane air cushion. It does automatically align each valve guide regardless of any misalignment or angular deflection thanks to live pilot technology.
Spindle control buttons located just behind the handwheel to change with ease the spindle speed rotation, switch spindle direction or reset the depth control measurement. Digital depth control accurate until 0.0004 in (0.01 mm). Displayed in inch or millimeter Two switch buttons to fastly activate both sphere and cylinder cushions, or lock them. Large handwheel for a better control of machining depth.
The machine is supplied with a universal clamping system allowing to setup and clamp cylinder heads with both vertical and inclined valve guides. Cylinder heads can rest straightly on parallels or stand in the tilting cradles. Several types of spacers or clamping bars are supplied to adapt the most common cylinder heads. The cradle can tilt from +42° to -15° from vertical.
The machine frame is equiped with LED lightning for an increased light ratio and a better energy saving.
INTEGRATED VACUUM TESTER
Graduated vacuum tester from 0 to -1 bar, linked to a vacuum generator on one end and to a foam pad on the other, in order to make a fast valve sealing check with the valve mounted on the valve seat, before disassembling the cylinder head from the machine.
CONTINUOUS SPINDLE SPEED VARIATION
This function allows the spindle speed a permanent oscillation around the nominal speed, in order to snap machining shattering when the cutting profile is too large.
