Frequently Asked Questions

What are the advantages of CNC Machining?

CNC machining provides designers and engineers with a cost-effective method to producing high precision metal and plastic parts. CNC machining biggest advantage is its versatility. It is an effective process at both low and high quantities, across a wide range of materials, and varying complexities.

What if I am not familiar with machining. Can I still work with you?

Yes, absolutely. Our team will work with you to make sure your design is machinable. If we identify any major issues, we will provide you with design for manufacturing feedback so you can make the necessary revisions to get your parts built.

What is Swiss CNC Machining?

Swiss CNC machining can produce small and complex geometries at tight tolerances and rapid cycle times. What separates these machines from other turning machines is the use of a sliding headstock and guide bushing. The sliding headstock feeds the bar stock through the bushing and cutting occurs very close to this point of support maximizing stability. This approach makes Swiss machining extremely effective for turning long, slender parts.

What inspection options are available?

When you start a project with us, we will make sure we understand your inspection needs. In our default inspection, QC will inspect against your drawing but no documentation will be provided. If you need a dimensional report or First Article Inspection report, we can accommodate that in our custom inspection offering.

Can you support expedited lead times?

Yes, Senturi has expedite options with both our domestic and international partners so you have multiple options for your budget. The timeline is dependent on the complexity of the parts and the quantity. Typically, we can deliver expedited parts to you in 5 days if built domestically and 10-12 days if built overseas.
