Kennametal has introduced a new line of PCD round tools for aluminum machining that delivers up to 10 times higher productivity than carbide tooling. The new line of drills, reamers, and end mills provides exceptional tool life and wear resistance even in very abrasive aluminum alloys and are available with very short lead times.
Kennametal’s new polycrystalline diamond round tools are available with short lead times that enable high-efficiency aluminum machining.
“Our new PCD round tools line enables our customers to machine aluminum significantly faster, for greater productivity on the shop floor,” says Michael Hacker, Product Manager, Kennametal. “In drilling and reaming operations, these tools consistently perform at cutting speeds of up to 900 m/min (3,000 SFM). Milling operations can be performed at an incredible 6.000 m/min (20,000 SFM) — far higher than non-PCD tooling”
With through-the-tool coolant capabilities and an MQL-ready interface, these PCD round tools are ideal for both rough and finish machining. Extremely sharp cutting edges and low-friction rake surfaces eliminate concerns over built-up.
The low-friction machining also produces superior surfaces in finishing operations, such as reaming. Surface roughness of Ra 0,1–0,8 μm (0.0025–0.02 μ-in) is achievable – far superior to conventional carbide tooling. PCD grade KD1410 assures extended tool life and is particularly beneficial in the high silicon content aluminum used to make automotive parts like engine blocks or cylinder heads.
The line of PCD end mills features:
- Six to 50 mm diameter tools
- Cutting depths up to 50 mm
- Center-cutting, roughing, and finishing geometries
- Various rake angles.
The PCD drill offering features:
- Six to 20 mm diameter in 0.5 mm increments
- Up to 5 x D
- Inch and metric sizes
The PCD reaming portfolio offers:
- Six to 20 millimeter in diameter in 1 mm increments
- Through and blind hole versions
- For larger diameters up to 42 mm, the PCD modular reaming system with KST coupling is available
“Many of these PCD round tools can also be requested as custom solutions to fit specific customer needs while still maintaining short lead times,” says Hacker. “Kennametal is leveraging its decades of experience with PCD tooling in the automotive industry to make this technology readily available to any manufacturer looking for a cost-competitive and highly productive solution for aluminum machining.”
