FVM-104160DC series has an extra wide column distance (110").
Chevalier's FVM double column VMC has a rigid and stable structure base on oversized columns, extra-wide spacing of box ways on a slanted Y-axis and close symmetrical design of the Z-axis. All models feature 30 HP spindle motors with two-speed gearbox and INA precision roller bearings.
"The series is perfect for lean, repeatable mass production of large and heavy workpieces for aerospace, power generation, wind turbine, oil exploration, heavy machinery, die-mold industry and heavy construction," said Chevalier's Chipcutting Sales Manager Herbert Hou. FVM series double column VMCs have large-capacity table size, starting at 86.6" x 70.8" and up to 240" x 135", with a table load of up to 44,000 lbs.
The rigid one-piece structure combined with an advanced control system is intended to provide flexible machining capabilities. The slanted Y and Z axes increase the slideway surface and distribute the load in the area. The oversize wide box ways are coated with Turcite-B and then cross-scraped by hand to help ensure adequate lubrication, smooth movement, reduced drag and optimum wear resistance. The four heavy-duty linear roller ways of the X-axis support the table and boost moving speed, reducing stick-slip problems caused from box way machines and increasing positioning accuracy. The machine net weight ranges from 70,400 lbs. to 160,600 lbs.
All axes feature Class 3 high-precision, double-nut, pre-tensioned ball screws. Optional oil circulation in the 80 mm large ball screws helps eliminate thermal buildup and ball screw deformation and maintain positioning accuracy and repeatability. The 50-taper, cartridge-type, air-purge, 6,000 RPM with 30 HP (35 HP optional) spindle is driven by a two-speed gearbox with low speed for extra-high torque output during heavy cutting. It generates a maximum torque of 449 ft-lbs. The tool set capacity is a 40-arm type with an optional 60-arm type.
A German INA two-directional roller bearing supports the axes and minimizes backlash. This enables stronger bearing support compared to the single ball type thrust bearing, according to Chevalier.
The chip channel, one on each side of X-axis table, is one piece with the casting and comes with individual chip augers. A high-volume, flood coolant wash down recirculates from a high-capacity coolant tank.
"After assembling, all Chevalier machines are measured and calibrated by state-of-the-art laser calibration and ball bar test equipment," said a company spokesperson. "This ensures precise verification and compensation of the machines, resulting in increase accuracy and repeatability."
