Robotized Machining: a dynamic high-speed paradigm for large metal frame and structural components
Robot-like flexibility meets machine tool stiffness and accuracy
Comau innovation puts the power of high-speed robotic machining in your hands with its new XMini carbon-fiber Machine Tool Robot. Strong enough to drill holes in aluminum, titanium and composite materials, XMini performs dry machining at a rate of 90 meter/minute with a 3g acceleration, thus reducing cycle times by up to 50% compared to standard machine tools.
XMini is the first robotized machine tool designed for high-speed, burr free, dry machining of large metal frames and structural components. With its modular and reconfigurable design, XMini can be easily integrated into existing automation lines, helping lower operational costs and protect CAPEX. Its 5-micron repeatability also grants optimal quality, productivity and Overall Equipment Efficiency. And because XMini was designed to handle bulky and complex parts, including battery boxes and components, it’s the perfect solution for the automotive, aerospace, energy and electrification markets.rated in just a few hours.
