Background

This project was the first work undertaken by Nautic Engineering Ltd for this marine engineering sector customer. We got involved as they had struggled to find a supplier willing to take on small quantity but high-quality machining work.

The Project

The project specifically involved the machining of bespoke hose tails, bungs and adaptors for a safety critical application in the marine engineering sector. A high surface finish of 0.8Ra was required due to the intended application, and this project involved tight tolerances on corner radii and the hose barbs, that required the use of precision tooling.

Materials varied from Super Duplex Stainless Steel to Aluminium Bronze. Nautic Engineering Ltd machine shop staff are highly experienced in machining heat-resistant super alloys (HRSA) and other exotic alloys, which allowed us to provide a competitive solution.

Initially, the work was programmed offline to test machine tool paths prior to the cutting of metal. The machined components were then CNC machined on our XYZ Machine Tools RLX 425 lathe and our RMX 5000 mill.

Following machining, a 100% inspection was conducted on all machined components, using first principal methods. Casting resins were also required to inspect some component features such as sealing grooves. The cast impressions were then sectioned and inspected on our optical projector. All threads were inspected to calibrated plug and ring gauges.

Finally, all parts were degreased in an ultrasonic bath prior being despatched to the customer.
