Burkhardt+Weber MCX 800

The Burkhardt+Weber MCX 800 is a large horizontal machining and boring center designed for high-precision machining of heavy, complex workpieces in aerospace, energy, and general heavy engineering. Burkhardt+Weber, headquartered in Reutlingen, Germany, has specialized in large-format precision boring and milling machines since 1923, and the MCX 800 represents the company's core expertise: rigid, thermally stable machine structures capable of maintaining micron-level accuracy over multi-hour cycles on workpieces that can weigh several tonnes.

The MCX designation stands for Machining Center with a cross-rail design, and the 800 designation refers to the 800 mm spindle head travel range. The machine uses a floor-plate (floor-type) configuration with a traveling column and a cross-rail spindle head, allowing the machining of extremely large workpieces that cannot be accommodated by a conventional rotary-table horizontal machining center. The spindle — typically an 80 mm or 100 mm boring bar spindle — delivers the torque and rigidity needed for large-diameter boring operations in steel, cast iron, and titanium alloys.

The MCX 800 is built on a heavily ribbed cast iron or welded steel base with high-force ballscrews and precision linear guideways on all axes. The thermal symmetry of the machine design minimizes thermal growth errors during long machining cycles — a critical attribute when boring large housings, gearboxes, or structural aerospace frames to tolerances measured in single-digit microns. Burkhardt+Weber integrates Siemens Sinumerik 840D sl as the standard control, providing full five-axis interpolation capability for complex contour work.

Typical applications for the MCX 800 include energy sector work such as turbine casings, compressor housings, and large pump bodies; aerospace structural components such as wing spars, bulkheads, and landing gear housings; and general heavy engineering including marine diesel engine blocks and large industrial gearbox housings. The machine is frequently equipped with a rotary table for indexed four-sided machining and an automatic head changer for switching between right-angle milling heads and boring heads without operator intervention.

In the large-format horizontal boring mill market, the MCX 800 competes with offerings from TOS Varnsdorf, Parpas, Juaristi, and WFL Millturn Technologies. Burkhardt+Weber differentiates through German manufacturing quality, close integration with the Siemens control ecosystem, and a service network centered in Central Europe with representation in North America and Asia. The MCX 800 is a machine for buyers prioritizing long-term accuracy retention and application engineering support over lowest acquisition cost.
