On-The-Fly WYE-DELTA Switching High-Capacity Cartridge Spindle (above)

Many Haas VMCs use the Haas Dual-Drivesystem: a dual-winding motor – Wye and Delta – with an electronic switch to change between the windings. Selecting the best winding for low-rpm or high-rpm cutting yields higher torque over a wider rpm range. The Haas Dual-Drive system also uses on-the-fly winding change to provide the wide power range necessary for constant surface speed cuts. The advanced design of our spindles provides high axial-thrust capability, while generating minimal heat. The front and rear bores and the OD of the spindle are finished in one operation. This guarantees perfect alignment between the bores and ODs, thus reducing bearing heat.To ensure long life, the spindle is pressurized to preventcoolant contamination, and an air/oil mixture is injected at preset intervals to ensure precise lubrication and long bearing life.
