Hard material does not automatically mean hard to cut

Innovation with traditional simple square inserts

In addition, radial insert clamping enables the inclusion of a chip gullet with a generous volume that answers the requirements of free chip flow when milling at high metal removal rates (MRR). Also, the tools of more popular diameters have internal channels, which are specially designed for machining with a high-pressure coolant (HPC) supply. Even these “simple” square inserts are characterised by a progressive cutting geometry that provide effective titanium milling.

Hence, if Helitang H490 and Millshred P290 are intended for productive roughing, and Helitang Fin for qualitative semi-finishing of titanium workpieces, the new Heliquad (real Heliquad) extended flute shell mills from an application point of view and provides high-efficiency milling with resulting surface conditions close to semi-finish conditions.

Iscar has been introducing a myriad of new products, each one aiming for the 3 P's: higher Productivity, Profitability and Performance:

New grades and coatings to enable cutting tools to machine faster, run cooler, resist built-up edge and last longer.

New geometries to reduce cutting forces, save energy, improve chip control and provide more edges per insert.

More versatile multifunction tools to support the "complete machining" trend on CNC mill-turn centers.

Stronger self-clamping designs on stationary tools, enabling them to withstand heavy duty interrupted cuts.

Turbo booster: powerful resistance to vibration

Iscar recently introduced the Ti-Turbo family of solid carbide endmills in a diameter range of 6 to 20 mm. The new family was designed for finishing operations and also for high-speed machining (HSM) of mainly slots, with the use of the trochoidal technique. Trochoidal milling features a small width and significant depth of cut, combined with a tool path dictated by a trochoid curve. Under such conditions, the tool “slices” metal up at a high rate. An engagement angle here is small and produced chips are very thin. This results in dramatically decreasing the thermal load on the tool.

Ti-Turbo endmills, of unique patent design, have seven or nine variable flutes with variable angular pitch (similar to the beneficial Chatterfree solid carbide tools) that ensures powerful resistance to vibration. That is why the new family is regarded as a true turbo booster in titanium milling.

Iscar’s Multi-Master versatile line of assembled tools with replaceable solid carbide cutting heads has been recently enhanced by the introduction of new, six-flute, fast-feed milling heads with central coolant holes. The ultra-fine grain carbide substrate of the heads, protected by the advanced AL-TEC coating technology, provides outstanding wear resistance and toughness. The heads are used in productive high-feed milling (HFM), resulting in significant reductions in the cycle times of roughing operations.

Manufacturers of titanium parts are constantly placing new demands on the producers of cutting tools. In order to meet these challenges, cutting tool producers like Iscar are forced to think outside the box on a regular basis. Iscar’s prolific R&D team continues to co-operate with many of the world’s leading manufacturers of titanium parts to ensure that the company retains its lead within this challenging sector.
