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.
Michael Hacker, Product Manager, Kennametal said: “Our new PCD round tools line enables our customers to machine aluminum significantly faster, for greater productivity on the shop floor. 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.”
High productivity with an extended product life
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-edge. Low friction machining also produces superior surfaces, in finishing operations, such as reaming. The 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.
Hacker added: “Many of these PCD round tools can also be requested, as custom solutions to fit specific customer needs while still maintaining short lead times. 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.”
