How Fine Machine Works delivered turn-mill machined mandrels in a corrosion-resistant alloy, on a time-sensitive schedule, with full material traceability.
Sample structure only. The project, customer type, specifications and results are placeholders; Si supplies the real details and approves whether the customer can be named. Each case study stays at about 400–500 words.
An oilfield service company needed mandrels for a downhole tool used in completions. The parts would operate under high pressure, extreme temperature, and corrosive conditions, and required tight concentricity between turned diameters and milled features.
Add the timing pressure, e.g. tools needed for a scheduled job or a fleet repair.
Drawings, material specification, and delivery requirements were reviewed before the order was accepted.
Mandrels were completed on a turn-mill system in a single setup, protecting the relationship between turned and milled features.
Critical features were verified with the Hexagon CMM and Micro-Trac / Gagemaker systems.
Coating or heat treatment, if any, was completed through approved sub-contractors, and parts shipped with material certs and a Certificate of Conformance.
