Question 1

What is the typical lead time for precision turned parts?

Accepted Answer

Our standard production lead time is 10–15 business days. For urgent validation, we offer an expedited 'Rapid Turning' service that can deliver functional prototypes in 3–5 days depending on material availability.

Question 2

What axial tolerances can PREMSA achieve?

Accepted Answer

We maintain a standard diameter tolerance of ±0.005". For critical fits, our multi-axis centers can reliably hold ±0.001" (0.025mm) with verified concentricity and cylindricity through CMM metrology. Use our ***interactive ISO 2768 chart***(/resources/charts/iso-2768-tolerance-chart), ***tap drill calculator***(/resources/tools/drill-tap-chart), and ***drill bit size chart***(/resources/charts/drill-bit-size-chart) when specifying holes and threads.

Question 3

Do you support 'Bar Work' for high-volume production?

Accepted Answer

Yes. Our facility is equipped with automated bar feeders supporting up to 3" (75mm) diameter for continuous 24/7 production, ensuring maximum throughput and competitive unit pricing for thousands of units.

Question 4

What are the benefits of Live Tooling on a lathe?

Accepted Answer

Live tooling allows us to perform milling, drilling, and tapping operations on the lathe. This 'done-in-one' approach eliminates secondary setups, reducing positional errors and significantly lowering the total cost-per-part.

Question 5

Can you machine complex threads and internal bores?

Accepted Answer

Absolutely. We specialize in precision ID work, including deep-hole boring and internal threading to ASME and ISO standards. We recommend providing a 2D print for any thread class or fit requirement.

Question 6

Is material traceability included in the quote?

Accepted Answer

Standard quotes include our basic CoC. Full material traceability (MTRs) and detailed dimensional inspection reports (including FAI) are available upon request during the RFQ stage.

Question 7

What is the maximum swing and length for turning?

Accepted Answer

Our standard work envelope supports parts up to Ø 12" (300mm) swing over bed and up to 24" (600mm) in length. For oversized or extra-long shafts, please contact our engineering team for a custom capability review.
