Non-standard Custom PCD Forming Reamers

High-Precision Custom PCD Forming Reamers for Advanced Materials & Complex Holes

Engineered for demanding applications requiring exceptional hole accuracy and specific geometric features, ZY SUPER HARD’s non-standard custom PCD Forming Reamers provide superior finishing solutions. Tailored specifically for industries like Automotive, Aerospace, and Electronics, these tools excel in machining challenging non-ferrous metals (especially high-silicon aluminum and copper alloys) and abrasive composites (CFRP/GFRP), delivering significantly extended tool life and impeccable surface quality where conventional reamers struggle.

Key Design Features and Performance Benefits:

• Customizable Forming Geometry: Go beyond simple hole sizing. These reamers are custom-designed to not only achieve tight diametrical tolerances (e.g., capable of H6/H7) and excellent roundness, but also simultaneously create precise forms such as chamfers, radii, lead-in tapers, or specific profiles at the entrance, exit, or even within the hole itself. This consolidates operations, ensures perfect feature relationships, and reduces cycle times.
• Premium PCD Cutting Edges: Utilizing high-quality Polycrystalline Diamond, selected for the specific workpiece material, the cutting edges offer extreme hardness and unparalleled abrasion resistance. This translates directly to significantly longer tool life compared to carbide reamers, especially in abrasive materials like high-Si Al or composites. This longevity maintains consistent hole size and finish over thousands of parts, drastically reducing tool change frequency and associated downtime.
• Solid Carbide Shank Construction: The high-rigidity solid carbide shank provides maximum stability, minimizing deflection and vibration, even during complex forming cuts or at higher speeds. This rigidity is essential for achieving superior hole geometry (roundness, straightness) and overall dimensional accuracy.
• Optimized for Challenging Materials: Specifically engineered cutting geometries and PCD grades excel in producing high surface finish quality (often reducing or eliminating the need for secondary finishing like honing or burnishing) when machining aluminum alloys, copper alloys, metal matrix composites (MMC), carbon/glass fiber composites, green ceramics, and other materials known for causing rapid wear on conventional tooling.
• Reliable & Efficient Performance: The robust combination of durable materials, precision manufacturing, and stable cutting action ensures reliable, consistent performance, boosting productivity and ultimately lowering the cost per finished, high-quality hole in demanding manufacturing environments.

Application Focus:

Ideal for complex hole-making applications requiring both precise sizing and specific form generation, such as:

• Automotive: Precision finishing and chamfering/radiusing of bores in aluminum valve bodies, transmission components, ABS manifolds, suspension parts.
• Aerospace: Creating accurate and formed holes (e.g., with specific lead-ins or countersinks) in aluminum alloy or composite structural parts, hydraulic/actuator components.
• Electronics: Machining precise mounting holes with chamfers or other features in aluminum housings, heat sinks, or potentially composite circuit boards.
