 Reverse Engineering Questions

Can you reproduce a part without original drawings?

Yes. Reverse engineering is our specialty. We carefully measure existing parts, determine materials, and create new documentation that allows us to machine accurate replacements.

Why is reverse engineering important?

Reverse engineering is critical when OEM parts are obsolete, drawings are unavailable, or lead times are too long. It allows businesses to get equipment back up and running quickly with custom replacement parts.

Do reverse-engineered parts perform as well as the original?

Yes. Our reverse-engineered components are manufactured with the same—or in many cases, improved—materials and machining accuracy as the original.

Precision Machining Questions

What sizes of parts can you machine?

We can machine parts up to 200 inches in length on our boring bar and produce intricate features as small as one-half inch on our vertical machining center.

What tolerances can you hold?

We specialize in tight-tolerance machining for both prototypes and production runs, ensuring parts fit and function as required.

What materials do you machine?

We are proficient with aluminum, mild steel, high-carbon steels, stainless steel, brass, bronze, nylon, and plastics of all types.

Do you provide grinding services?

Yes. We offer OD grinding, surface grinding, and Blanchard grinding to achieve smooth finishes and precise tolerances.

 Can you weld as part of your machining services?

Absolutely. We provide MIG and TIG welding for steel, stainless steel, and aluminum.

Prototype Questions

Do you offer prototype machining?

Yes. We create CNC prototypes to test fit, function, and performance before moving to production machining.

Can prototypes be made in production-grade materials?

Yes. Prototypes are often produced in the same materials as the final part, so testing results are accurate.

How do prototypes transition to production?

Once a prototype is approved, we use the same setups, tooling, and documentation to move seamlessly into production runs.

Production Machining Questions

Do you handle small production runs?

Yes. We offer flexible production machining, from short runs to large-scale batches.

Can you maintain consistency in high-volume runs?

Yes. Our processes and fixtures ensure repeatability and accuracy across hundreds or thousands of parts.

Do you refurbish production parts?

Yes. In addition to machining new parts, we also refurbish worn or damaged components to extend their service life.

Shipping, Delivery, and Service Questions

Do you serve customers outside of Wisconsin?

Yes. While we are located in Kaukauna, WI, we ship parts nationwide and serve customers across the U.S.

What is your typical turnaround time?

Turnaround depends on the complexity of the job and production volume, but we are committed to clear communication and on-time delivery.

Do you provide quotes before starting a project?

Yes. We provide clear, competitive quotes based on your specifications, materials, and delivery requirements.

Can I visit your shop in person?

Yes. Customers are welcome to visit our Kaukauna facility during business hours to discuss projects in detail.
