High-Capacity Cartridge Spindle

The advanced design of our spindles provides high axial-thrust capability, yet generates minimal heat. The front and rear bores of the housing and the OD of the spindle are finished in one operation. This guarantees per- fect alignment between the bores and ODs, thus reducing bearing heat.Pre-loaded angular contact bearings are used through-out, with the two forward bearings separated by a large spacer to enhance radial stability – enabling heavy cuts in steel. To ensure long life, the spindle is pressurized with air to prevent coolant contamination, and an air/oil mixture is injected automatically at preset intervals to ensure precise lubrication and long bearing life.

On-The-Fly WYE-DELTA Switching

Many Haas HMCs feature the Haas Dual-Drive system, which consists of a dual-winding motor – Wye and Delta – and an electronic switch to change between the two windings. Selecting the best wind- ing for low-rpm cutting and the best winding for high-rpm cutting yields higher torque over a much wider rpm range. The shift-on-the-fly capability maximizes acceleration/deceleration rates for more chip making and less waiting.
