Custom Brazed PCD Boring Tools for Internal Machining
Overview
Custom Brazed PCD Boring Tools are engineered for ultra-precision internal machining of non-ferrous materials, including aluminum alloys, magnesium alloys, composites, and engineered plastics. At Aoshiji® Custom Tool, we design and manufacture brazed PCD boring bars that deliver exceptional rigidity, long service life, and superior surface finish. Compared to indexable insert boring tools, brazed PCD tools provide maximum stability and accuracy, making them ideal for deep-hole boring, fine-tolerance reaming, and precision internal turning applications.
Applications
Aerospace components with deep bores and tight tolerance requirements
Automotive engine blocks, cylinder heads, and transmission housings
Precision machining of hydraulic and pneumatic components
High-speed CNC boring of non-ferrous alloys, composites, and die-cast housings
Internal turning, fine reaming, and custom bore profiles requiring diamond tooling
Key Features
Brazed PCD cutting edges – Superior wear resistance and long tool life in non-ferrous machining
High rigidity design – Stable cutting performance with minimal deflection in deep-hole operations
Precision boring capability – Maintains microns-level accuracy in bore roundness and straightness
Custom geometries available – Tailored designs for reaming, internal turning, and complex bore shapes
Smooth surface finishing – Achieves Ra ≤ 0.2 µm in aluminum and composite machining
