The Aerospace industry demands highly complex machined parts and relies on Little Lakes to deliver custom built components such as horn antennas for microwave communications satellites.

Our Work

Aerospace: Microwave Communication Components

A Little Lakes’ customer required a very demanding component with 1.0 mm wall thickness and internal features with ultra-smooth surfaces. The initial destructive analysis identified tool chatter marks within the deep recesses of the part that would not be acceptable. By relocating certain setscrews we carefully frequency-tuned the cutting tool, removing internal harmonics and creating a chatter-free toolpath. Creative problem solving combined with deep experience and a dedication to customer satisfaction is one of Little Lakes‘ hallmarks.



Automotive part companies have turned to Little Lakes for more than 50 years to deliver exact tooling used in high volume parts manufacturing.

Our Work

Automotive: Powder Metal Tooling

Near perfect vertical surfaces were required on a tool feature for a Little Lakes’ automotive customer. We designed the toolpath so that hand polishing was not required, and then used the identical toolpath on all other similar features on the tool. It takes the right tools, and the knowledge of how to use them, to make the perfect tooling surface.


Our Work

Automotive: Flow Forming Tooling

Sometimes bigger is better, especially when milling features with tight radii into hardened materials like D2 or DC53. On our big Makino horizontal mill, the spindle and the parts holding are super stable, eliminating any vibration that could mar the quality of the final tool. Our customers’ flow forming tools are the product of this perfect alignment of equipment and know-how.


Alternative Energy

Alternative energy companies count on Little Lakes to deliver custom built tooling used in the production of solid oxide fuel cells.

Our Work

Energy: Powder Metal Tooling

A highly accurate surface across the entire tool, time and time again, was specified by an energy sector customer. To achieve this, the surface features of the tool were first milled into copper and then carefully EDM burnt into the tool’s active surface. Our dedicated 3D optical micro CMM provides the reassurance and proof that what we deliver on our promises.
