Ram and head
• The ram is made of pearlitic grey cast iron, quality EN-GJL-300 (UNE-EN 1561 standard), with a hardness of 190-220 HB, and is dimensioned and robustly reinforced with inner ribs to absorb the cutting and weight forces, and studied by finite elements.
• The ram has two size-45 rolling linear guide ways with recirculation rolls carriages, closed and protected against contamination.
• Mechanical compensation to get perpendicularly of main axis with the table
• Main motor with 2 speed reduction gearbox
• Automatic universal milling head 2,5° x 2,5°
• Both bodies of spindle head are made of spheroidal graphite cast iron, quality EN-GJS-HB155 (UNE-EN 1563 standard), with a hardness of 130-180 HB.
• The Spindle head is made up of two parts joined at 45º, which rotates around each other and are joined to the front part of the ram.
 Hardened and ground Klingerlberg-type epicyclical taper gears.
 Hardened and ground spindle shaft DIN 5480 (gear type).
