All the main components of the machine are made of cast steel and workpieces of up to 1,000 mm can be machined with speed and precision. When developing this series, the key issues were to ensure excellent technical performance and availability, while designing machines that were easy to use.

The VMC 850B machine type offers a table clamping surface measuring 1,000 x 500 mm, while the table’s maximum load capacity is 600 kg. It also has the exceptional axis travels measuring 850 mm for the X axis, 560 mm for the Y axis, and 650 mm for the Z axis. 24 different tools are available for the BT/SK 40 spindle, which can be operated with a maximum speed of 8,000 to 15,000 rpm. The tool magazine is positioned directly on the stand and provides the required tool quickly and precisely by means of the automatic tool changer.

The machining center is able to complete even difficult machining with a high torque both reliably and with minimal vibrations, thanks to high-precision linear guides, cast iron guides for the Z axis, and a strong ball screw drive. The motor has been positioned directly on the spindle to ensure a powerful drive system, reducing start-up and braking times, as well as enhancing accuracy and offering shorter machining times.

The sturdy linear guides enable high rapid traverse rates of up to 32 m/min and keep cost-intensive non-productive times to a minimum. Coolant nozzles and a chain-type chip conveyor reliably transport chips away. Meanwhile, a Fanuc control system and a 90 deg swivel operating panel make the equipment easy and convenient to operate.

The machine is also equipped with a swiveling NC rotary table made by Tsudakoma, tools made by ISCAR, and a workpiece measuring system made by Renishaw.

Product Description

• Rigid frame
  Main components incorporate cast iron with vibration dampening and thermal characteristics for high rigidity and accuracy.
• Rapid speed
  The rapid speeds for X/Y/Z are 32/32/30 meters/minute. Linear guideways minimize non-cutting time, thus improving machining efficiency.
• Easy-to-use control panel
  The Fanuc 0i-MD CNC system is easy to use, and the control panel (which swings 90 degrees) provides effortless, intuitive operation.
• Large Machining Envelope
  The Z axis travel of 650 mm. makes the work-piece envelope much larger than other machines of the same table size can provide.
