A Literal “New Spin” on Hybrid Milling/Grinding Machines

Mitsui Seiki’s Vertex hybrid machine borrows a jig grinder’s motion to complement high precision five-axis milling.

“The concept is to emulate jig grinding equipment,” says Robb Hudson, CEO of Mitsui Seiki USA, when describing a new family of Vertex five-axis hybrid vertical machining/grinding centers in booth 338519. Hudson explains that this concept is literally a “new spin” on milling/grinding hybrids, because the machines can apply a part spinning process that produces tangential planetary work spindle alignment, much like the U-axis motion of jig grinding equipment. Combine this with high speed 3+2 or full five-axis milling that is capable of 0.0003-inch (5.5 µm) precision, and the result is a machine that can carry out critical applications such as lights-out machining of die/mold, optical and tooling components, Hudson says.

The Vertex Hybrid G 55-5X machine on display has two larger siblings in the family, the 75-5X and the 100-5X. The show machine is demonstrating its capabilities with a combination of milling and grinding operations on a D2 steel plate, hardened and heat-treated to 60 to 62 HRC. A form milling tool is roughing and pre-finishing corner relief, followed by a form-grinding wheel for finishing. After a rounded triangular pocket is milled in the part’s center, a variety of grinding wheels form critical step features.

“We are claiming it has CMM-level precision because the engineered accuracy and rigidity meet volumetric calibration according to ISO10320-2 using the latest FANUC 3D volumetric compensation features, while enabling us to apply in-process 3D measuring capability traceable to the National Institute of Standards and Technology,” Hudson says. He adds that the machine’s structure, which features hand-scraped guideways, is configured to attain positioning accuracy in the X, Y, and Z-axes of 0.000040 inch (0.001 mm), ±6 arc seconds in the A axis, and ±4 arc seconds in the C axis.

“But the grinding aspect of this machine is the cool part,” Hudson says. “It’s not tacked-on. We have automatic, in-process grinding wheel dressing, size measurement and wheel calibration, plus an advanced thermal compensation system to enssure size consistency”

Hudson invites attendees to check out the machine for themselves. “They can see that this is not just a spin we put on the story.”

The Biden Administration Releases its Trade Policy Agenda

Meanwhile, another cabinet secretary with a big role to play in economic policy is confirmed.

Meanwhile, another cabinet secretary with a big role to play in economic policy is confirmed.

On Monday the Biden administration’s Office of the United States Trade Representative (USTR) released the 2021 Trade Policy Agenda and 2020 Annual Report, a product mandated by the Trade Act of 1974. In it, USTR lays out the current standing of trade agreements with dozens of countries; reviews recent trade enforcement activities, and lists its priorities on topics like labor rights, intellectual property protection, digital trade, trade of manufactured goods, and agricultural trade. There’s also a chapter that reviews U.S. participant activity at the World Trade Organization.

The whole thing is like 300 pages long, with no action scenes, like the big truck chase from 1980’s The Road Warrior, which is a great movie, possibly the greatest, full stop. Anyway, the accompanying fact sheet – which is basically a rewording of the report’s introduction – is a little more digestible.

This is an important document because, boiled down, it’s a big values statement. What’s included in it reflects political priorities, and the way that arguments are made in it reflect corresponding policy positions. For example, Todd Tucker of the Roosevelt Institute noted this on Twitter:

the whole thread is worth a read

President Biden has vowed to be a pro-worker president, and the rhetoric is showing up in his administration’s trade policy papers.


Putting all of this rhetoric into action will depend on the people he puts in charge to do it. That includes Gina Raimondo, the governor of Rhode Island who today was confirmed as the U.S. Secretary of Commerce in a 84-15 Senate vote. Raimondo worked in venture capital before getting elected to public office in 2010, and has earned support from manufacturers in her state for her work on stuff like small-business R&D grants and apprenticeship programs.

As the new Commerce secretary, Raimondo will inherit issues like the maintenance of a technology export ban list on which Trump’s Commerce Department placed Chinese companies like Huawei and Hikvision. And the Washington Post notes she also “must resolve questions about the future of Trump administration regulations restricting U.S. companies’ reliance on Chinese suppliers of telecommunications hardware and software.” This will tie in directly with the Biden administration’s stated goals of building domestic manufacturing supply chains for industries it’s deemed critical, like semiconductor chip fabrication.

She’s also going to be responsible for the maintenance of the broad steel import tariffs that were raised in 2018. The Biden administration has said it’s reviewing them. The Alliance for American Manufacturing thinks they should not be lowered unilaterally, damaging an industry on shaky footing in a pandemic economy.

Secretary Raimondo at the Commerce Department will have a large role to play in the economic recovery the administration hopes to accomplish with its Build Back Better plan. Another important figure is Katherine Tai, who’s expected to be confirmed as the USTR in a vote on Wednesday. Read more about her here.
