Burkhardt + Weber (B+W) has incorporated the stiffness and power of its heavy-duty MCX horizontal machining centres into a new smaller model — the MCC 630.

In so doing, the company says it has created one of the most rigid and powerful machines in its class for producing prismatic components weighing up to 1.5 tonnes (including the fixture).

In the UK and Ireland, the machine is available from the Gosport-based sole agent, Geo Kingsbury Machine Tools Ltd (www.geokingsbury.com).

The four-axis machine (including C-axis rotary table) has twin 630mm (optionally 630 x 800mm) pallets and a nominal 1m3 working envelope. The external dimensions are 8 x 3.3 x 3.5m.

The MCC 630 can deliver 1,300Nm of torque continuously, if the 41kW gear-driven spindle is chosen instead of a 30kW/300Nm motor spindle (there is a further alternative of a new +45/-110deg tilting spindle of identical power, which adds a fifth CNC axis).

Standard spindle speed is up to 6,000rev/min (optionally 10,000rev/min), while an ISO50 tool interface can be specified instead of the standard HSK-A100. The tool magazine has 64 pockets as standard, although this number can be doubled.

Large-diameter table and spindle bearings, widely spaced (size 65) linear roller guideways and twin ballscrew drives for the Y axis contribute to the machine’s stiffness, as does the ribbed FEM-optimised cast-iron structure.

Component accuracy is said to be maintained even when taking heavy cuts in steel or titanium, for example.

High levels of productivity are provided by a cutting-feed force of 17.5kN and 7m/sec2 acceleration to 60m/min rapids in the linear axes, which are fitted with linear scales for feeding positional data back to the Siemens Sinumerik 840D sl control.

B+W says it integrates a high level of Industry 4.0 monitoring and networking capability into its machines, offering data acquisition and communication for efficient production, process safety and timely maintenance.
