Tight Tolerances Where Soft Materials Fight Back

Plenty of shops say they machine aluminum, stainless steel, and plastic. Far fewer can hold tight tolerances and thin features in them, because soft materials deform, burr, and distort in ways that harder metals do not. That is the work this facility is built for.

The approach is disciplined. This is a nominal shop that uses as little tolerance as possible, machining to 0.001 inch, even when the allowable tolerance is plus or minus 0.005 inch, so customers never have to worry about tolerance stack-ups when mating these parts with others.

For more than 50 years, the team has done this for makers of some of the world’s most sophisticated measurement and diagnostic devices, where nothing less than exceptional accuracy will do.

Minneapolis Milling for Complex Geometries

Multi-axis milling is where complex parts take shape. A new 5-axis machine handles intricate geometries in a single setup, with table sizes up to 20 by 40 inches for larger work.

Depth of equipment keeps it moving, with more than 20 horizontal and vertical milling centers on the floor. On site that includes fifteen three-axis vertical mills, one four-axis vertical, one five-axis vertical, and four three-axis horizontal mills, enough range to meet the most complex milling requirements without queueing behind other jobs.

Precision Turning for Twin Cities Manufacturers

Turned parts get the same precision. The facility runs eight CNC lathes that machine parts up to 8 inches in diameter, and every one is equipped with sub-spindles, live tooling, a Y-axis, and bar feeders.

That setup lets the team turn and mill a part in the same operation, which cuts handling and holds accuracy on complex components. On site, the turning capacity includes one two-axis lathe and seven three-axis lathes with live tooling.

The Discipline Behind Our Precision

The Minneapolis operation is led by Robert Berg, who runs Ham Lake with a focus on precision, process discipline, and continuous improvement.

With a strong engineering foundation and deep expertise in lean manufacturing, Robert has built a team that consistently delivers tight tolerances, thin-wall geometries, and high-quality surface finishes in the metals and plastics where deformation and burrs are common pitfalls. Customers rely on him when parts cannot fail, when complex parts must hold tolerance, and when cosmetic finishes matter as much as function.

Common Questions About CNC Machining in Minneapolis

Q.
What CNC machining services are available at the Minneapolis-area facility?

A.

The facility offers high-precision CNC milling and turning, including multi-axis and 5-axis milling, live-tooling lathe work, and full tight-tolerance quality control. It specializes in short-to-medium production runs of metal and plastics.

Q.
What materials do you specialize in machining?

A.

The facility specializes in aluminum, stainless steel, brass and plastics, including PEEK, Delrin, and PTFE. These materials are prone to deformation and burrs, which is exactly where the team’s expertise makes the difference.

Q.
How tight are the tolerances you can hold?

A.

The facility is a nominal shop, which means it machines to as little tolerance as possible. For a tolerance of plus or minus 0.005 inch, the team machines to 0.001-0.002 inch, so parts mate cleanly without tolerance stack-ups.

Q.
Do you offer Just-in-Time, Kanban, or stocking programs?

A.

Yes. The facility runs short-to-medium production on a Just-in-Time or Kanban basis and offers stocking programs on request, backed by 100% on-time delivery maintained for over 25 years.

Q.

Q.
What makes Dahlquist by Fathom different from other CNC machining shops?

A.

Two things set it apart. First, it is a nominal shop, so it holds tight tolerances and thin features in materials that deform, burr, and distort where other shops struggle. Second, it backs that precision with a delivery record few can claim, 100% on-time for over 25 years, plus Just-in-Time and stocking programs.
