Tacchella Elektra

    Universal grinding machines for round, non-round and polygonal workpieces

    Tacchella Elektra universal grinding machines are the ideal solution for a wide range of requirements, such as grinding shafts, tool holders, workpieces for general precision mechanics, punches or pump gears – as individual pieces, in small or large quantities. Machining of different diameters or interpolations is also possible without any difficulties. These universal grinding machines can be used to clamp round, non-round and polygonal workpieces weighing up to 350 kg between the centers and grind at lengths up to 1,640 mm and heights up to 260 mm.

    ADVANTAGES

    HOW TO BENEFIT FROM TACCHELLA ELEKTRA UNIVERSAL GRINDING MACHINES

    Enhanced performance

    The monobloc machine bed on Tacchella Elektra grinding machines is made of stabilized and heavily ribbed cast iron and intercepts the thermal changes and vibrations that arise during grinding to ensure outstanding quality of the ground workpieces.

    Top precision

    The grinding wheel carriage (X-axis) slides on hardened guides with preloaded roller shoes. Movement is generated by means of a high-precision recirculating ball spindle, which is coupled directly to the digital AC BRUSHLESS motor. Motion control is performed using an optical absolute measuring system. The table (Z-axis) moves on flat/ prismatic guides with an intermediate layer of low-resistance material with improved properties to prevent stick-slip phenomena.

    Maximum flexibility

    The potential for combination of different sizes, versions, and center heights means that 27 versions of Tacchella Elektra universal grinding machines are available. The tailstock is manually operated, but it can also be automatically controlled by pressing a button and via pedal controls.

    Ideal ergonomics

    The workpiece headstock uses a swiveling base with a micrometric adjustment device. Clamping onto the table is performed using a self leveling system, which facilitates repositioning in the longitudinal direction. A pneumatic system for weight reduction makes it easier to move the tailstock on the table.
