Four propeller blades for a newly built commercial tugboat required high precision machining prior to installation. Our team finish machined the bores per OEM dimensions and within the expedited timeline.
Project:
- Part: Propeller Blades (4x)
- Details: 90″ dia.
- Customer: Marine Engine Parts and Service Provider
Challenges:
- Critical timeline – fast turnaround time required.
- High-precision machining required to correct the bore dimensions. Existing tapered bore was incorrect and had to be re-machined to match the shaft taper. Very little machining stock was available so precision set up and machine work was required.
Engineered Solutions:
- Set up the blades in VTL.
- Adjust VTL ram to match bore taper.
- Machine existing bore to the finished dimension per OEM specifications and print.
- Install bore plug which must have 80% contact with ID surface.
- Record all final dimensions and taper.
- Quality inspection with documentation photos before shipping.
- Prep for shipping.
- Transportation to and from drydock site.
Results:
- All technical specifications were achieved.
- Propeller blades (4x) were completed and delivered within the installation schedule.
