Alpha Precision Group (APG) has achieved massive weight reduction in workholding fixtures by leveraging 3D printing technology. APG successfully reduced the weight of chuck jaws used in turning operations by a remarkable 77%. The transition from conventionally machined jaws to 3D printed ones not only lightened the load but also optimized clamping pressure, addressing challenges of part deformation during machining.
The journey began with APG’s adoption of metal 3D printing in 2018, primarily for part iteration and creating durable fixtures for CNC machining. The company’s exploration led to the development of chuck jaw assemblies for turning cam gears, a solution now patented and available for external customers. By utilizing bound metal deposition (BMD) technology, APG engineered lattice structures and optimized geometries, achieving substantial weight reduction without compromising functionality.
Further enhancements came with the acquisition of a Moldjet 3D printer from Tritone Technologies. This proprietary process enabled APG to produce chuck jaws with even greater intricacy and efficiency. The Moldjet-produced jaws weighed merely 492 grams, demonstrating a remarkable 77% reduction compared to their machined counterparts. This not only saved material but also improved productivity by enabling faster spindle speeds during machining operations.
The impact extends beyond weight reduction; the redesigned chuck jaws facilitate higher sustained spindle speeds without compromising clamping force, promising increased efficiency for machining operations. APG’s success story highlights the transformative potential of 3D printing in optimizing industrial processes, paving the way for enhanced performance and productivity in manufacturing applications.
