EMCO Redesigns Maxxturn 65 G2 for High-Precision, Dynamic Machining

The Maxxturn 65 G2 has been redesigned. With its modular design, the machine offers a wide range of options for specific customer requirements.

Posted: July 17, 2021

With the Maxxturn 65 G2, the high drive power of the main and counter spindles combine with optimum torque characteristics to ensure economic efficiency in the machining of steel and in the high-speed machining of aluminum.

Twelve driven tools and a Y-axis ensure highly accurate results in complex milling and drilling operations. With numerous automation solutions and the EMConnect digital process assistant, the 65 G2 is state of the art and enables low manpower
production in operation.

Machine Structure

The core of the machine is the 40-degree inclined bed. Designed as an extremely rigid and compact welded steel construction, it is the basis for a robust and precise lathe. Reinforcements provide additional rigidity in zones exposed to higher stress.

As a further development of the Maxxturn 65 G1, the machine impresses with its modern and innovative design. The optimized integration of the chip conveyor ensures compact dimensions. Instead of belt drives, spindle motors are used on the main and counter spindles, which ensures a particularly wide speed range of up to 5,000 rpm and extremely good concentricity properties. Three main spindle sizes are available depending on customer requirements: Standard Ø 65 mm/BigBore Ø 77 mm/SuperBigBore Ø 95 mm. A symmetrically designed headstock, temperature sensors at the bearing points, and liquid cooling ensure high thermal stability.

The C-axis is part of the basic machine equipment and allows the positioning of the spindle within a resolution of 0.001 degrees. Due to the directly flanged encoder, the C-axis is well suited for contour-precise milling; a hydraulic holding brake (option) can be additionally activated. The Y axis is also integrated in the basic machine structure and set at 90 degrees to the X axis. Extremely short projection lengths form the basis for solid turning and drilling operations and for contour-free milling operations. Absolute measuring systems are installed in all linear axes – position dispersion as per VDI3441 in X/Y/Z: 0.0035/0.0035/0.004 μm as
standard/0.002/0.002/0.002 μm as an option, with glass scales and laser measurement.

Machine Configurations

The Maxxturn 65 G2 has numerous modular options and is available in different versions:

  • MT65 G2 M: including tool drive, C-axis and tailstock
  • MT65 G2 MY: including tool drive, C-axis, Y-axis and tailstock
  • MT65-G2 SM: including counter spindle, tool drive and C-axis
  • MT65-G2 SMY: including counter spindle, tool drive, C-axis and Y-axis

On the MT65M-G2 with tailstock, the tailstock is mounted on the roller guide track and can be moved automatically over a length of 500 mm. A drag steady rest with Ø 8-101 mm is available as an option. This ensures even more flexible use of the machine, e.g. for shaft machining.

On the MT65S-G2 with counter spindle, the counter spindle head is seated on its own roller guide track and can be moved automatically over a length of 580 mm. The spindle is driven by an integrated spindle motor with liquid cooling. A stroke-monitored parts ejector, flooded with coolant, ensures safe removal of the finished parts. In addition, a 12-station VDI30 turret (optional VDI 40) with single-motor technology is available. A servo motor powers the driven tools or the swivel movement. No lift-off and indexing with directional logic are the result. Each station can accommodate driven toolholders; alternatively, a 12-station BMT55 turret with direct drive up to 12,000 rpm or even a 16-station BMT45 turret can be integrated.


The customer can choose between the SINUMERIK ONE or the FANUC 31i-B control system. The control panel on the MAXXTURN 65 G2 is height-adjustable on the right and can be swivelled, which ensures the best ergonomics. 22″ multi-touch screens improve the view of individual control functions.

The optional digital process assistant EMConnect stands for connectivity and networking of the production environment and helps with the comprehensive integration of customer- and system-specific applications around the machine control and the production process.

EMConnect can be updated and configured, and the selection of available apps is constantly being expanded. For example, the Shopfloor Management app serves as an option for machine and production data acquisition, enabling monitoring of all machines and organization of processes in the production area. Apps for minimizing downtimes are also available with EMConnect.


The EMCO SL1200, IRCO ILS-MUK 7012 or 10012, FMB Turbo 5-65 or 8-75 and Top Automazioni Xfiles bar feeders are available for efficient production. The EMCO gantry loader ensures fully automatic loading and unloading of the workpieces and seamless interaction between the machine tool and the loading device. If required, flexible robot automation can also be offered.
