Haas uses hardened-steel bearing packs rolling on hardened-steel ways. Built using the same precision grinding technology utilized in bearing manufacturing, they feature zero clearance and full load-carrying capacity in all directions.
Haas uses only premium-quality ballscrews and guides that meet the highest quality standards in the industry. Haas ballscrews are anchored at both ends and pre-tensioned, then inspected for 100% parallelism to the axis guides.
• Through-spindle coolant:
The Haas through-spindle coolant options improve tool life and allow higher speeds, deep hole drilling and blind pocket milling. The result is high productivity and reduced cycle times. Haas engineers have designed a special seal which disengages when the system is not in use. This exclusive design feature extends the life of the system. The standard TSC option provides 300 psi (20 bar) at a flow rate of 1.5 gallons (5.7 L) per minute, and 250 psi (17 bar) at 4 gpm (15 Lpm). The 1000 psi option has a max flow rate of 6 gpm (23 Lpm), and requires separate (customer-supplied) 3-phase power. In both systems, actual pressure will vary with the diameter of the coolant passages in the tool.
