HMC Cuts Large Aerospace Parts
IMTS 2018: The FZH HMC from Zimmermann is designed for parts as large as 630" × 122" × 39".
The FZH HMC from Zimmermann is designed for parts as large as 630" × 122" × 39". Minimum part size in the X axis is 161".
Said to be well-suited for the aerospace industry, the machine features an updated pallet handling system and traveling column. The traveling column is water-cooled and avoids deviation increases as the slide extends. Rather, as the guide carriage distance increases, rigidity increases as well. The stepped drive guide contributes to constant geometry along the Z axis, as well as rigidity in sensitive areas of the workpiece.
Speed changes the rules. To maximize metal removal rate with a high speed spindle, follow some fundamental tooling considerations and mill at just the right rpm.
Cryogenic machining achieves dramatic tool life gains not by flooding the cut, but by refrigerating the tool.
The recipe for best results is simple: Start with a rigid machine, add a high pressure through-the-spindle coolant system, then combine these with the right drill geometry plus the right speeds and feeds.
