Thanks to the large working area of the machine, it is possible to optionally add a partition for pendulum operation, a second integrated rotary table or NC axis with counter bearing. This reduces the setup time for tool changes and increases the quality of the workpiece. RF or laser touch probes are optionally available for this purpose. Touch probes allow automatic measurement of tools and workpieces.

All guides and screw drives are permanently grease-lubricated via a central lubrication system, while oil films are kept from forming in the coolant system. The machining centre can be equipped with numerous options, such as coolant filter systems with high pressure pumps with up to 60 bar through the spindle, which permit the use of high-performance tools with internal cooling. The compact machine bed of the moving column machining centre is a heat-treated, welded steel structure that provides a torsion-resistant and stable base for all components and machining operations. Alternatively, for 4- and 5-axis machines, tool magazines with 40, 60 or 120 pockets can be mounted on the travelling column. In addition to a stationary tool magazine with 40 pockets (optionally up to 60 pockets) on the left side of the machine, up to a further 60 tool pockets can also be installed on the right. This allows axis accelerations of up to 4 m/s 2 and rapid traverses of up to 50 m/min to be achieved. On the MMV 3200, ball screws, which are directly connected to the motors via backlash-free couplings, transmit the forces and movements in the X, Y and Z axes. Likewise, a 40-, 60- or 120-pocket alongside column tool magazine is optionally available for the 4- and 5-axis variants. The drum magazine of the MMV 3200 has 40 tool pockets as standard this can be enlarged on request and supplemented by an additional magazine with a further 40 or 60 tool pockets. The two large work area doors ensure easy loading and unloading of workpieces and fixtures, even when using a crane. Noteworthy customer benefits are their workshop-oriented programming. Besides Siemens and Fanuc, Heidenhain controls are operated in boring and milling machines by many companies. UnionChemnitz will offer the new Heidenhain TNC 640 as an option for all machine types in the future. Both spindle variants are permanently grease-lubricated. New TNC 640: comprehensive integration of turning technology. These powerful features allow users to handle large and heavy workpieces of up to 5000 kg. The travelling-column machining center MMV 3200 from Emco is equipped with a motor spindle with 46 kW spindle power, a torque of up to 170 Nm and a spindle speed of up to 15.000 rpm (18 000 rpm HSK-A63).
