Emco’s Maxxturn 65 G2 Designed for Versatile Machining

Emco’s Maxxturn 65 G2 

Emco’s Maxxturn 65 G2 has been redesigned to offer more high-precision, dynamic machining. With a modular design, the machine offers a range of options for specific customer requirements. The high drive power of the main and counter spindles, combined with optimum torque characteristics, are designed to ensure economic efficiency in the machining of steel as well as in the high-speed machining of aluminum. There are 12 driven tools and a Y-axis to ensure quality results in complex milling and drilling operations. With numerous automation solutions and the optional Emconnect digital process assistant, the Maxxturn 65 G2 enables low-manpower production in operation.

The core of the machine is the 40-degree inclined bed, which is designed with a rigid and compact welded steel construction, making it the basis for a robust, precise lathe. Reinforcements provide additional rigidity in zones exposed to higher stress. The machine features optimized integration of the chip conveyor to ensure compact dimensions. Instead of belt drives, spindle motors are used on the main and counter spindles to ensure a wide speed range of up to 5,000 rpm and good concentricity properties, the company says. Three main spindle sizes are available, depending on customer requirements, with the following diameters: Standard 65 mm, BigBore 77 mm and SuperBigBore 95 mm. A symmetrically designed headstock, together with temperature sensors at the bearing points and liquid cooling, also work to ensure high thermal stability.

The C-axis is part of the basic machine equipment and enables the positioning of the spindle within a resolution of 0.001 degree. Due to the directly flanged encoder, the C-axis is well suited for contour-precise milling. An optional hydraulic holding brake can be additionally activated. The Y-axis is also integrated in the basic machine structure and set at 90 degrees to the X-axis. The company says that extremely short projection lengths form the basis for solid turning and drilling operations as well as contour-free milling operations.
