Table Load kg for more options see page Table Size mm A large number of accessories are available. ACCESSORIES DETAILS 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 mm, driven by a servomotor and ball screw. Clamping spindle taper SK50, BT, or CAT. Torque transferred to the spindle through a two-speed planetary gearbox. Gears change automatically according to the programmed rpm. Standard spindle support sleeve of mm. HEADSTOCK CARRIAGE Headstock carriage in a cast iron casting, provides LIGHTING OF THE WORKING AREA movement of headstock in axis Y controlled by ball screw and along box guideways. Guideways are lubricated by oil. COLUMN AND BEDS Rigid, tough, precise, designed to absorb vibrations during machining. The main framework of the machine, the longitudinal and cross-wise beds, slides, and the column base are made of cast iron GG30 with the addition of Cr and Cu; the functional surfaces of all the ways of the box guides are hardened HRC and ground. Servomotors and ball screws drive the CNC rotary table along X axis, headstock on Y axis, and column along Z axis. Ball-screw on axis Y is equipped with an electric BEDS brake at the bottom. Separate servo drives on all axes, controlled digitally, provide the means for linear, circular, and helical interpolation. X, Y, and Z axis are moving on hardened box guide- ways or wide linear guideways. CNC ROTARY TABLE Thanks to the simple design and excellent components, FERMAT CNC rotary tables require minimum maintenance and adjustments during their lifetime. Maximum load is up to tons. 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 MASTER - SLAVE SYSTEM 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.
