High-speed and high feed milling is increasingly prominent with the ever improving performance of the modern machine tool. Adding to its already extensive milling product portfolio, Tungaloy UK has now introduced its new TungForceFeed small diameter high feed milling cutter.
With a tool diameter range from 8 to 16mm, the new TungForceFeed caters for a diameter range smaller than the existing DoFeed Series. Perfect for the mould and die industry and general machining applications, the new TungForceFeed is available with both a high-feed insert and an R2 insert line that can be applied to machining a diverse range of materials from alloy steel, stainless and hardened steels through to cast iron, titanium alloys and heat resistant alloys such as Inconel and Hastelloy.
The high-feed insert is suitable for general high-feed milling applications and subcontract machine shops whilst the R2 insert designation is ideal for full profiling and semi-roughing to semi-finishing processes. The R2 insert has a free cutting geometry that eliminates chatter and improves surface finishes whilst the built-in wiper reduces burr formation. Applying the latest PremiumTec coatings, the inserts are offered in Tungaloy’s AH3225 and AH8015 grades. The AH3225 incorporates a Nano multi-layered coating that optimises cutting edge integrity and increases wear, fracture and oxidation resistance. Similarly, the AH8015 grade has a hard coating layer that improves performance on difficult to machine materials.
Particularly prominent in high-feed machining applications is the design of the toolholder and Tungaloy once again impresses with its innovative new design that is perfect for shoulder milling, slotting, and ramping, plunging and helical feed drilling.
The toolholder pockets are designed with a positive inclination that works in synergy with the thick corner inserts. Supporting this, the toolholders have a particularly robust M2 screw that reduces screw neck shearing that can be commonplace during high cutting force applications. Furthermore, the screws improve operator handling, clamping and precision when combined with a precise seat location. The positive insert inclination also improves swarf evacuation, which is critical for high-feed machining applications. The inclination reduces chip adhesion and the likelihood of premature insert failure – a systematic symptom of poor chip evacuation and adhesion.
The tool body line-up is available with a short shank, long neck shank, undercut shank and a modular interchangeable head configuration. The EXLS toolholder and the modular screw-on TungFlex are both available from 8 to 16mm diameter with the option of 2, 3 or 5 insert seats with a tool shank length from 75 to 120mm.
