Mighty USA introduces its Viper PG5 five-axis gantry machine, which is a high-wall, gantry-style, simultaneous five-axis double-column VMC designed for large-size and heavy workpieces.

The machine has a built-in 60-hp, 15,000-rpm, HSK A100 spindle and a maximum table load of 115,000 lbs. Table sizes are available as large as 137" × 236", and German INA roller linear guideways on all three linear axes are designed to provide high rigidity and fast feed rates, the company says.

The machine uses Hiwin C3-class ballscrews. The X and Z axes use dual ballscrews, and all linear axes use ballscrews with cooling systems to avoid heat generation caused by ballscrew movement. According to the company, ballscrew cooling promotes dynamic three-axes performance by maintaining a constant temperature.
