High productivity tool The new IMT Tacchella Crossflex AS grinding machine is the best solution for all grinders focusing on high productivity and flexibility. Crossflex AS is equipped with a Ø 500 mm high cutting speed CBN grinding wheel and three different systems for positioning the wheel holder unit, including a motor B axis for automatic positioning, programmable at will through the SIEMENS 840D sl or Fanuc32i CNC (opt.). Thanks to the wide set of accessories and modular options available, this is the perfect solution for any production and machining requirement over crankshafts, pump gears, general precision engineering, spindles, etc., for both small and large batches, including multidiameter machining or interpolations. In addition, the brand new workhead driven by a built-in motor (C-axis) and the new hydraulic tailstock allow this machine to grind round, non round and polygonal workpieces weighing up to 150 Kg between centers. The range can be used for a grinding lengths of 1100 and 1600 mm with center heights of 180 mm (opt. 250). From Cross-flex success, the evolution of the species The Crossflex range is founded on the success of the Cross-flex, from which it inherits its configurability and flexibility, preserving its concept and adding sophisticated innovations to it, such as the system to monitor maintenance (it signals any maintenance that needs to be performed) or the ENERGY SAVING system to lower electrical energy consumption: all by just simply pressing a button. Crossflex is perfect for the sectors of general precision engineering, automotive, electric motors, etc. Thanks to its broad range of accessories, it allows users to identify the best manufacturing modes, ensuring satisfaction of even the most demanding customers. Multi-brand synergies Designed with the most modern technology, the new IMT Tacchella Crossflex AS combines an incredibly short cycle time with a fast re-tooling process, which is the fruit of upgrades introduced in the new and intuitive software. The new Crossflex uses a technological platform born out of the team work of engineers of the entire IMT Group and which is shared in common by its marketed brands, ensuring an ideal price: quality ratio and brief delivery times. Success guaranteed Improved surfaces, improved dimensional tolerances, improved repeatability. With the new X and Z axis grinding wheel carriage made of stabilized iron castings and sliding movement on high precision prismatic-plane guides with interposed anti-friction material, mechanism which ensures greater stiffness and better slide. With direct drive transmission thanks to preloaded, high precision recirculating ball screws built-in to the Brushless engine (which lowers the need for extraordinary maintenance operations while making them easier). With control via absolute optical linear encoders. Minimized set-ups The new interactive operator interface “Tool Operator Package” installed to the machine control system, simplifies the part-program creation process, making any adjustments that need to be made easier and more accessible. Moreover, all the accessories of the series (post-process, vibration sensors, self-centering rests, automation) are directly managed by the interface. The new Crossflex series To limit consumptions means to achieve eco-sustainability or, simply put, to safeguard the environment. With the ENERGY SAVING system to lower electrical energy consumptions, all you have to do is “press a button”. But replacing a filter at the right moment is also important, and with the Maintenance Operator Package, it’s easier. This is the new driving concept behind the Crossflex series. MACHINE BED The new Crossflex AS features a single structure in stabilized iron casting, widely ribbed, and fitted with peripheral channels for collecting the coolant. Designed relying on cutting-edge 3D technology for parametric solid modeling, verified through FEM analysis, this structure perfectly dampens temperature fluctuations and vibrations resulting from the grinding process, ensuring excellent dimensional quality of ground pieces. “X” AND “Z” AXIS WHEEL HOLDER The Crossflex AS new grinding wheel carriage slides on high precision prismaticplane guides with interposed anti-friction material preventing stick-slip and offering a high dynamic efficiency of the grinding machine. The cross guides, a transversal “X” axis and a longitudinal “Z” axis, allow to minimize the overall floor space and to rationalize the layout of the hydraulic and electric systems. The guides slide thanks to high precision recirculating ball screws connected directly to the AC brushless motor with digital adjustment. The wheel holder head for external grinding can be positioned from -5° to +26°34’ in the manual and automatic modes or through the B Axis. Axis positions are constantly monitored by an absolute linear measurement system, fitted with a pressurization unit, with a double guide protection: bellows and telescopic type. The model Crossflex AS tops off the product range with a version dedicated to the high cutting speed technology using a CBN grinding wheel, with peripheral speed of up to 120 m/s. WORKHEAD The universal workhead of the new Crossflex AS is perfect for overhung grinding and between centers, with fixed and rotary spindle. The new workhead is made of high precision bearings ensuring top precision with roundness error below 0.001 mm, and lies on a swiveling base, with a micrometric adjustment device. The continuous speed variation is controlled by a digital adjustment AC Brushless motor, while a pneumatic system eases the movements during machine set-up. It is as well possible to fit a workhead featuring a C Axis for machining threads and non-round parts, such as cams, eccentrics, regular polygons, and customized shapes. TAILSTOCK The tailstock of the new Crossflex AS is driven hydraulically. It is equipped with a safety device controlling clamping between centers and axial load adjustment. It also features a device for workpiece cylindricity micrometric adjustment, which is built in the tailstock, together with a pneumatic system, which helps tailstock movement on machine set-up. As an option, at the working table can be abbed a W Axis module with variable length, which allows for the fast adjustment of the length of the part to be ground, thus minimizing set-up times. GENERAL PRECISION ENGINEERING The new Crossflex AS, designed to grant high productivity and flexibility is used for machining batches of high precision parts in the general engineering field. The new Crossflex AS grinds with absolute precision the external cylindrical diameters of various mechanical parts in the general precision engineering field. SHAFTS The new Crossflex AS, designed to respond to the ever evolving innovations in the automotive field, is suited for completely grinding drive transmission mechanical shafts. The new Crossflex AS grinds with absolute precision the external cylindrical diameters of crankshafts and gearbox shafts. PUMP GEARS The new C rossflex AS, designed and manufactured relying on the experience and synergy of all the engineers of the IMT group, is suited for machining high-precision mechanical products such as pump gears used by most of the industrial fields (automotive, food, plastic, petrochemicals, etc.). The new Crossflex AS grinds the external cylindrical diameters of pump gears with absolute precision. SPINDLES The new Crossflex AS, produced according to cutting-edge technologies aimed at improving the quality of grinding and at reducing the impact on the environment, is perfect for machining high precision mechanical parts of machine tools, such as spindles. The new Crossflex AS grinds with absolute precision the external cylindrical diameters spindles of machine tools.
