Avia MCV 1680

The Avia MCV 1680 is a large-format CNC vertical machining center built by Czech manufacturer Avia for heavy-duty 3-axis machining of oversized structural, mold, and tooling components. With a 1,680 mm X-axis stroke, it addresses applications where the MCV 1260 falls short — long beam parts, large die sets, aerospace brackets, and energy-sector components that demand a wide table and substantial spindle power in a vertically configured machine.

Avia's MCV 1680 follows the brand's established design philosophy of heavy cast iron construction throughout the bed, column, and saddle. The box guideway system on the linear axes provides high rigidity under interrupted cuts and heavy face milling loads, making the machine well suited for roughing hard materials like tool steel, nodular cast iron, and titanium alloy. The wide stance of the column base enhances structural loop stiffness and minimizes deflection when machining at full table extension.

The spindle on the MCV 1680 is designed for high torque at low-to-mid RPM, befitting the machine's large-part focus. A geared two-speed head or direct-drive spindle with output in the range of 22–30 kW ensures the machine can take aggressive cuts in ferrous materials without stalling. While the standard maximum spindle speed of 6,000–8,000 RPM is moderate compared to high-speed machining centers, this is appropriate for the large-diameter tooling and heavy chip loads the machine is designed to handle. An optional higher-speed spindle is available for facilities that also need to finish aluminum or non-ferrous parts on the same platform.

The MCV 1680 accommodates Siemens Sinumerik 840D sl or 828D controls, giving operators access to advanced features including CYCLE800 for 3+2 positioning if the optional tilting rotary table is fitted. The machine's control architecture supports DNC integration, shop floor networking, and modern CAM post-processor connectivity. A high-capacity coolant system with through-spindle coolant option supports deep cavity machining and extended-reach tool applications.

For European job shops, toolmakers, and tier-1 automotive suppliers requiring a large-table VMC with predictable EU-origin quality and service support, the MCV 1680 represents a compelling alternative to importing comparable machines from Taiwan or purchasing from premium European OEMs at significantly higher cost. Avia's factory in the Czech Republic and its established distributor network across Central and Western Europe provide accessible technical support and spare parts supply chains.
