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.
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.
Air floating tables, cylinder heads up to 350 kgs can be moved back and forth without any effort and then locked by two powerful pneumatic jacks.
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.
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.
The machine frame is equiped with LED lightning for an increased light ratio and a better energy saving.
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.
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.
