SERDI S 100 ES L Basic Machine

SERDI S 100 ES L Basic Machine

Machine designed on the working principle of the double air-float patented centering system, with a built-in motor spindle delivering massive torque, a very high rigidity machining head and frame, being able to carry very heavy cylinder heads.

3 KW BUILT-IN MOTOR SPINDLE

A massive 3 KW (4 HP) built-in motor-spindle with maximum torque from 40 to 385 rpm and a maximum speed of 840 rpm. Stator cooled by heat sink and fan. Rigid heavy duty motor-spindle of 4.5’’ (116 mm) diameter welcoming a motor coupled to a planetary gearbox for a powerful 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.

BEAM EXTENSION

This extra length on the beam is available to ease the mounting and unmounting of large and heavy cylinder heads on the table and extend the machining head stroke.

CONTROL PANELS

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.

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.

FIXTURE TABLE

The support table is mounted on two guiding rails. It can stands a weight up to 850 kgs back and forth. The table is then firmly tighten on the rails thanks to four pneumatic clamps.

LED LIGHTNING

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.
