A current trend in turning tools is to continue to develop high-speed and large-cut cutting tools.
Kennametal's KB9640 is an integral CBN turning tool with a CVD aluminum alloy multi-layer coating on its surface. It is said that the CVD aluminum alloy multi-layer coating has good resistance to cracking and good resistance to chemical wear and crater wear of diffusion and oxidation, and the tough CBN underlayer is more suitable for large depth of cut. High reliability and efficient processing. Therefore, its main purpose is to carry out high-power roughing and finishing of pearlite gray cast iron materials and roughing of hardened steel, chilled cast iron and hard-plated materials. The company has also developed several new carbide tools for high-volume processing of aerospace, medical device and food manufacturing materials. Among them, KC5510 and KC5525 are characterized by nano-grain, high-power cutting and surface coating with high-performance TiAlN coating, and can extend tool life at high cutting speed, plus micro-geometry of chip breaker. Designed to ensure very high cutting stability and excellent workpiece surface roughness.
High-speed machining of cast iron can use the newly developed CA4010 hard gold-containing tool from Kyocera Ceramics. A major feature of the tool is its multi-layer composite coated surface. The outermost layer is a TiN coating resistant to oxidation; the middle is a thicker fine-grained Al2O3 film to further prevent oxidation of the tool surface at high cutting speeds; the bottom layer is a TiCN coating that resists tool breakage and microcracking. The tool is also designed with a new ZS-type chipbreaker geometry, which is said to improve the cutting stability and cutting edge strength of the insert, reduce vibration during machining, and is suitable for intermittent and heavy-duty cutting.
The patented Xcel tool is produced by Sandvik and its main structural feature is the use of 80° inserts for machining. It is said to provide high-speed machining, and is more suitable for semi-roughing superalloys and titanium alloys than diamond-shaped inserts. It is said that in machining, the 80° insert can be machined with a 45° plunging angle, just like a square insert, with the advantage of easy programming and reduced tool wear. The tool also features corners that can machine complex shaped parts, excellent accessibility in limited spaces, and the ability to machine in both directions. Compared with the circular blade, it has the characteristics of reducing the radial force and keeping the chip thickness constant.
In addition, Sandvik has introduced the new CoroTure XS small turning tool for turning the inner groove and small threads (such as threads with a hole diameter of f1mm). When used on a CNC machine in Switzerland, the blade is loaded into the mast bore, a coolant supply is required to improve chip evacuation and effectively cool the cutting edge. The aluminum rods are supplied in diameters ranging from f10 to f25.4 mm.
Sometimes, the dimensional changes of the part itself, not the machined material, cause problems in the machining process. Seco-Carboloy's newly developed TP3000 is used for part turning with large dimensional changes. It is said to be capable of interrupting cutting and high feed rate machining of large parts or small batches of large parts.
For high-productivity turning, the main feature of the newly developed HeliTurn system from Iscar is the ability to clamp the helical cutting edge insert in the tangential direction. When cutting steel, it can reach a depth of 8mm and a large amount of cutting (about 1.2mm / r). The four helical cutting edges of the insert ensure a positive radial rake angle, resulting in less cutting forces and improved tool life and high stability of the cutting edge. The system is equipped with a tool holder for clamping 25 or 32 mm square.
