New MC's Offer Complete Machining of Large and Heavy Parts in One Clamping

With the MMV 4200 / 5200 / 6200 models, EMCO introduces an extension to its MMV series, featuring enlarged travel paths (X= 4200 / 5200 / 6200) in response to increased demand in the travelling column machine segment.

The machines with 3, 4 and 5 axes can be used for complete machining of very large and heavy parts in one clamping.

The proven technology of the MMV 3200 has been kept in the new models: a high-performance motor spindle with 0 -- 15,000 rpm speed range, 46 kW spindle power and up to 170 Nm torque. 40 tool pockets are available as standard, optionally expandable up to 120 pockets.

Thanks to the new modular system, customers do not have to choose between a smaller machine or one that is too large; variable sizes are possible up to 6,200 mm. The main difference between the MMV 4200 / 5200 and 6200 and the previous model is the X-axis drive, which uses a rack-and-pinion system instead of ball screws. This ensures dynamic, fast and precise feed during machining. The demand for these high-performance machines comes mainly from the petroleum industry, railroad industry and intralogistics.


The extremely compact machine bed of the travelling column machining centers is a heat-treated, welded steel structure that provides a torsion-resistant and stable base for all components and machining operations. The production of large and heavy workpieces up to 8,000 kg is enabled by a powerful 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).

Both spindle versions are grease lubricated. The new versions of the previous model support complete machining of very long and heavy workpieces without re-clamping. A new modular system ensures a variable choice of workpiece sizes up to 6,200 mm during machining. The large work area doors ensure easy loading and unloading of workpieces and fixtures, even when using a crane.

With this system, rapid traverses of up to 60 m/min can be achieved.

The machine versions with swivel head (B-axis) and rotary table (C-axis) are ideally suited for 5-axis simultaneous machining. Both the swivel head and the rotary table are driven by dynamic torque motors.

State-of-the-art digital control systems from Heidenhain (TNC 640 -- 24" monitor*) or Siemens (840D sl -- 22" monitor) ensure user-friendly machine operation.

The ergonomic design of the MMV series with its movable control panel creates ideal working conditions for the operator, who can swivel and rotate the control panel in the working area as well as move it along the longitudinal axis without interrupting the machining process, while keeping the workpiece in view at all times.


The machining centers can be equipped with numerous options such as coolant filtering systems with high pressure pumps with up to 60 bar through the spindle, which permit the use of high-performance tools with internal cooling. All guides and rack drives are permanently grease lubricated via a central lubrication system, while oil films are kept from forming in the coolant system.

State-of-the-art touch probes allow automatic measurement of tools and workpieces. RF or laser touch probes are optionally available for this purpose. This reduces the setup time for tool changes and increases the quality of the workpiece.

Thanks to the large working areas of the MMV series machines, it is possible to optionally add a partition wall for pendulum operation, a second integrated rotary table or and NC axis with counter bearing.

Features such as the automatic door operation or thermal compensation of the milling spindle make the machining centers even more efficient.


EMCO's MMV 3200 travelling column machining center is designed for heavy chip removal and precision cutting. The MMV 3200 is available in 3- or 4-axis versions with a B-axis. For 5-axis simultaneous machining an integrated torque rotary table is added as a 5th axis.

The machine is suited to the requirements of the automotive or aerospace industry as well as to those of machine manufacturers or job shops.
