External cylindrical grinding machine TACCHELLA CROSSFLEX series

for gearsfor shaftworkpiece

Tacchella Crossflex external cylindrical grinding machines combine the highest yield rates and flexibility in one machine. Crossflex external cylindrical grinding machines are equipped with a conventional grinding wheel (Ø 610 mm) or a CBN grinding wheel for high-speed cuts (Ø 500 mm). The workpiece headstock with built-in motor (C-axis) and the hydraulic tailstock for weights up to 150 kg between the centers allow the grinding of round, non-round and polygonal workpieces up to 1,600 mm long and 180 mm high (optional 250). ADVANTAGES HOW TO BENEFIT FROM TACCHELLA CROSSFLEX EXTERNAL CYLINDRICAL GRINDING MACHINES ENHANCED PERFORMANCE The bed of the Crossflex external cylindrical grinding machine offers a monolithic structure made of stabilized cast iron. It is extensively ribbed and has peripheral channels to collect the coolant. The machine bed dampens the temperature fluctuations and the vibrations in the grinding process and guarantees an excellent dimensional quality of the milled workpieces. MAXIMUM PRECISION The universal workpiece holder head has a swiveling base and a device for micrometric configuration, so it is perfect for smooth grinding and grinding between the centers using fixed and rotating spindles. Precision bearings ensure minimum tolerances of less than 0.001 mm of roundness. GREATEST FLEXIBILITY Comprehensive accessories and grinding wheels on which profiles can be created enable copy-machining on strips up to 150 mm. The machine thus meets all requirements, including those in the machining of electric motors, molds, shafts and gear pumps. In small and large quantities, for multi-diameter machining or interpolations.
