Datron Dynamics' MLCube high-speed milling machine is the second machine in the Cube series designed for improved speed, accuracy, flexibility and durability. The machine features high spindle speeds and a large, 60" × 45" work area suited to nested or batch milling of many small parts from sheets of metal or engineered plastic, as well as long aluminum extrusions. Typical applications include work in the defense, aerospace, electronics, energy, medical part prototyping and production industries. When working with sheet material, the machine can integrate the company's line of vacuum tables for quick setup and workholding during the milling process.
Brushless, direct drives on all axes provide fast acceleration and shorter cycle times with feed rates ranging to 866 ipm. The machine can be configured with various high-speed spindles including a 1.8-kW, 48,000-rpm spindle; a 2-kW, 60,000-rpm, liquid-chilled spindle; and a 3-kW, 40,000-rpm, liquid-chilled spindle. The latter offers greater horsepower for heavier machining, as well as the flexibility to mill a wider range of hard materials. HSK-E 25 tool holders, available with the 1.8- and 3.0-kW spindles, provide additional precision and less than 1 micron of runout, the company says. Palletized workholding and advanced probing are available for reduced setup time and increased part quality and uniformity.
