Guided TA Tool Overcomes Cross-Hole Drilling Hurdles in Moldmaking
Allied Machine & Engineering’s Guided TA drill for moldmaking applications is used for producing water lines.
Allied Machine & Engineering’s Guided TA drill for moldmaking applications is designed to overcome two primary hurdles associated with cutting waterlines in large molds: tool failure in deep cross holes, and chip evacuation. Intersecting channels often connect off-center or at non-perpendicular angles. The interrupted cuts can cause premature tool failure if cutting forces are imbalanced. In addition, deep holes can present issues with proper chip formation and removal.
To ensure stability, the Guided TA drill features minimal clearance between the holder and blade. It also incorporates guided wear pads for straightness and stability and two adjustable Torx Plus screw pins for total indicator runout reduction via simple diameter adjustment. These features are said to enable the tool to drill to an 84" depth of cut while producing balanced cutting forces and small chips for optimal evacuation.
This shop finds stable milling speeds quickly using a systematic pattern of test cuts.
By systemizing die making into repeatable steps, Dies Plus, a division of Otto Engineering, is using its machinists to effectively make dies. This solution relies on a paperless color-coding system to convey the tolerances machinists need to hit in order for tool and die makers to do the final fitting.
While aluminum molds are commonly used to create prototypes or to serve as stopgap bridge tooling, they are starting to receive greater attention for production work. This shop’s approach to creating aluminum molds in one day to three weeks is the same for each of these situations.
