The constant cutting speed lathe head, melted in special stabilized Meehanite cast-iron, gets the motion by an A.C. brushless motor that enables, through the references of the optical ruler of the X axis and a simple digital readout, to change the spindle rpm according to the diameter of the piece in working. So we get a constant cutting speed, modifiable in every time utilizing a potentiometer with instantaneous regulation. The surface finishing, especially in facing operations, is very nice.
The speed gear range (2 ranges with continuos change) is mechanical, the spindle hole is very wide (111 mm).
The bed is covered on the whole length and has sturdy structure with stiffening ribs that assure an absolute undeformability. It is melted in special cast-iron Meehanite, it is distensioned in bracket, and its slide guides are largely sized, induction hardened and carefully ground in such a way as to maintain an absolute precision to the surface. Very useful is the natural gap allowing to work very large pieces typical of bigger machines which are less maneageble.
