PCD Reamer for Precision Holes
For manufacturing operations demanding ultimate accuracy and surface finish in non-ferrous and abrasive composite materials, the PCD Reamer stands as the definitive solution. Crafted from Polycrystalline Diamond, the hardest cutting tool material commercially available, this tool delivers exceptional performance where traditional carbide or high-speed steel reamers rapidly degrade. Its primary advantage lies in achieving and maintaining tight tolerances and micron-level surface finishes over exceptionally long production runs. This makes it the go-to tool for high-volume, precision-dependent industries such as aerospace, automotive engine manufacturing, and electronics.
Our Wear-resistant PCD Reamer is engineered to withstand the abrasive wear encountered in materials like carbon fiber composites, silicon-aluminum alloys, and green ceramics, dramatically reducing tool change frequency and machine downtime. For optimal chip evacuation in through-hole applications, our Straight Flute PCD Reamer offers superior performance. When processing blind holes or interrupted cuts, the Spiral Flute PCD Reamer provides smoother cutting action and improved finish. Regardless of the flute geometry, every tool in our lineup is a High-precision PCD Reamer, manufactured under stringent quality controls to ensure consistent, reliable results that meet the most demanding specifications.
The <产品名字> is built upon a robust carbide body, onto which a precisely lapped PCD cutting edge is brazed. This construction combines the extreme hardness and wear resistance of diamond with the structural integrity of carbide. The PCD tip is meticulously ground and polished to achieve a cutting edge with near-zero runout and a razor-sharp finish, which is critical for producing holes with minimal burnishing, no tearing, and a true cylindrical form. Its exceptional thermal conductivity also helps dissipate heat from the cutting zone, further protecting the workpiece material from thermal damage and preserving the metallurgical properties of aerospace-grade alloys.
Below are the detailed technical specifications and standard parameter options for our PCD Reamers. These configurations are designed to cover a wide range of standard and specialized applications.
- Body Material: Micro-grain carbide substrate for maximum rigidity.
- Cutting Edge Material: High-grade Polycrystalline Diamond (PCD) blank.
- Primary Applications: Non-ferrous metals (Aluminum, Copper, Brass), Abrasive Composites (CFRP, GFRP, MMC), Sintered Metals, and Ceramics.
- Standard Coating: Uncoated (PCD edge), with optional AlTiN coating on the carbide body for non-cutting surfaces.
- Quality Standard: 100% inspected for critical dimensions, cutting edge sharpness, and concentricity.
| Diameter (mm) | Flute Length (mm) | Overall Length (mm) | Shank Type | Flute Type | Tolerance (h6) |
|---|---|---|---|---|---|
| 3.00 - 6.00 | 10 - 20 | 60 - 80 | Straight Shank | Straight / Spiral | ±0.004 |
| 6.01 - 12.00 | 20 - 40 | 80 - 100 | Straight Shank | Straight / Spiral | ±0.005 |
| 12.01 - 20.00 | 30 - 50 | 100 - 120 | Straight Shank / Weldon | Straight / Spiral | ±0.006 |
| 20.01 - 30.00 | 40 - 70 | 120 - 150 | Weldon Shank | Spiral | ±0.008 |
For optimal performance, we recommend using our reamers with a high-pressure coolant system to ensure efficient chip removal. Machining parameters such as speed and feed should be adjusted based on the specific workpiece material, with typical cutting speeds ranging from 150 to 300 m/min for aluminum alloys. A proper, concentric setup with minimal tool overhang is crucial to achieve the stated tolerances and tool life.
