ACCESSORIES DETAILS

16 HEADSTOCK STANDARD HEADSTOCK Rugged, powerful, precise. The headstock is made from cast iron GGG60 and is equipped with a digitally-controlled servomotor turning the spindle, continuously regulating its rpm. Spindle travel W axis of 800 mm, driven by a servo- motor and ball screw. Clamping spindle taper SK50 150, BT, or CAT . Torque transferred to the spindle through a two- speed planetary gearbox. Gears change auto- matically according to the programmed rpm. Standard spindle support sleeve of 250 mm.

RAM EXECUTION OPTIONAL The headstock moves up to 700 mm towards the RAM EXECUTION workpiece. Combined reach of spindle travel and ram stroke maximum 1430 mm optionally 1500 mm . Ram stroke drives deep into the heart of the work- piece while maintaining the highest rigidity and ac- curacy. Ram stroke is controlled by servomotor with gear- box and ball-screw. All deflections compensated through geometric fea- tures of ram and headstock. COLUMN AND BEDS Rigid, tough, precise, designed to absorb vibra- tions during machining. Column frame, beds, slides, base, are made of rein- forced cast iron GG30. BEDS Maximum rigidity and firmness of column and bed achieved through annealing; guideways and box ways hardened 56 HRC . Servomotors and ball screws 80 mm in diameter drive the CNC rotary table along X axis, headstock on Y axis, and column along Z axis. Y axis servomotor is equipped with mechanical brake. Separate servo drives on all axes, controlled digital- ly, provide the means for linear, circular, and helical interpolation. CNC ROTARY TABLE AND CLAMPING PLATES Thanks to the simple design and excellent com- ponents, FERMAT CNC rotary tables require CNC ROTARY TABLE minimum maintenance and adjustments during their lifetime. The CNC rotary table consists of three main parts - bed, slide, and rotary clamping plate. The clamping plate is fit to a cross roller bearing that secures high load capacity, no stick slip, minimum friction. Slides and clamping plate are castings. 2 servomotors with pinions provide the rotary movement on B axis, master/slave, no backlash. The rotary positioning of the table uses an absolute angle encoder increment of ; the table is set in position, and held in place by hydraulic brakes. Clamping plates can be used for machining parts.
