“Where Innovation Never Stops!” is the slogan that appears on the walls of the production facilities at Iscar headquarters and has been synonymous with the company for several decades. The COVID-19 pandemic did not interrupt the innovation process, and between 2020-2021 Iscar introduced the NeoLogIQ marketing campaign comprised of advanced cutting tools and tooling solutions for modern metalworking. The significant changes in manufacturing, such as intensive digitizing, the shift to electric drive in the automotive industry, and growing precise workpiece fabrication, have emerged new demands for cutting tools. Notwithstanding, the accelerated pace of changes sharpens the demands and requires more Iscar NeoLogIQ products that answer to modern age machining. “Machining with No Boundaries” is the NeoLogIQ mindset.
CHAM-IQ-DRILL, the family of assembled drills that mount exchangeable carbide heads, is now upgraded with new heads in the diameter range of 33-40 mm. These heads can be mounted on any drill possessing the appropriate pocket size. The main feature of the new heads is a multifunctional cutting geometry, which enables effective drilling of various engineering materials such as steel, stainless steel, heat-resistant special alloys, and titanium (ISO P, M, and S groups of application) assuring hole precision within IT10-IT9 accuracy grades. Iscar’s customers will benefit from using the new heads which guarantee to maintain less stock of tools for machining diverse materials.
The Iscar LOGIQ-3-CHAM (shown in top photo) is also based on the concept of exchangeable carbide heads with three flutes for improved productivity and is now supplemented by new carbide heads for achieving a nearly flat bottom hole. Flat bottom holes are necessary for screw head sockets, spring seats, washer ports, etc. The heads ensure drilling up to an eight-hole depth-to-diameter ratio without a pre-hole. The new design facilitates generating holes with a nearly flat bottom by use of a single pass. The heads are mounted on existing LOGIQ-3-CHAM tools that significantly expand the application range of the family and reduce inventory costs.
So how do you increase the drilling depth? Use a longer drill?
MODUDRILL is a family of modular drills with replaceable carbide heads that carry indexable inserts and provide an alternative solution. Mounting an exchangeable extension holder on a drill body increases the drilling depth by an additional 200 mm when machining holes in a diameter range of 33-40 mm.
In high-speed reaming, a combination of a carbide reaming head with a rolling device in one single tool results in a short operational time for achieving accurate hole diameter along with a mirror-like surface finish.
Key aspects in turning
A modular tool concept is the way to reach high versatility. NEOSWISS (Fig. 2), a new tool system with quick-change heads, follows this concept. There are different types of heads for indexable inserts. The system is suitable for turning, parting, grooving, and threading applications. By use of a unique high-clamping-force mechanism, the heads are mounted on a toolholder. The mechanism provides an accurate cutting edge position each time and utilizes high position repeatability. The system intended mainly for Swiss-type machines enables removing heads and replacing inserts within the tight confines of CNC machining centers.
Iscar has developed a new lever dual lock securing mechanism for improved clamping rigidity intended for ISO turning inserts. The new design, referred to as the COMBI-D-LOCK family, combines the advantages of two conventional clamping methods by the use of a lever and a top clamp. An insert is locked in two directions from the top and the bottom. This provides better stability and rigidity, and in comparison, to the conventional lever improves tool life and increases productivity.
LOGIQ-F-GRIP features a new highly advanced tool family for parting solutions. The central component of the family is a robust tool block that mounts a four-pocket adapter. There are cases when the rib, a reinforcement element of the block, interferes and prevents clamping the block on typical turret positions. NeoLogIQ overcomes this problem by providing additional blocks with the rib placed on the alternative side of the block. The revolutionary LOGIQ-F-GRIP parting system was designed to achieve extra stability and vibration-resistant high productivity parting and grooving operations. The highly engineered LOGIQFGRIP is an assembled tool block that comprises a unique durable holder and a high-stiffness quad blade with pockets for mounting inserts.
Innovations in milling
NEODO S890 (Fig. 3) is a family of 90° indexable face mills for rough and semi-finishing operations. The mills mount durable square double-sided inserts with 8 cutting edges. NEODO S890 facilitates face and square shoulder milling while providing an additional option for milling close to shoulders where there are workpiece or work holding fixture constraints. Iscar customers have requested additional corner radii and tool diameters, therefore, this tool family was expanded with additional pressed-to-size inserts with a 0.8 mm corner radius and cutters in diameters 32 and 25 mm including endmill design configurations.
A durable double-sided round insert is now available. The combination of an innovative pocket design and a special peripheral shape of the insert provides reliable insert clamping and fail-proof insert indexing. Depending on the depth of cut, there are up to six insert indexes on each side (up to 12 indexes total). When indexing, there is no need to remove the insert clamping screw. The main application of the new cutters is for rough and semi-finish milling complex surfaces, especially in die and mold, power generation, and aerospace parts.
The range of solid carbide endmills has been expanded by adding new tool diameters and corner radii.
Iscar Spinjet (Fig. 4), a family of coolant-driven high-speed compact spindles for small diameter tools, intended to upgrade existing machines to high-speed performers, is now supplemented with Micro 90 intended for miniature rotating tools in milling, drilling, countersinking, thread milling, engraving, chamfering and deburring operations. Micro 90, made of a solid titanium shell and assembled from only six parts, enables rotating velocities that range from 35000 to 53000 rpm while the main machine spindle remains idle.
The chuck thickness is a factor that limits the working space of a tool. This factor often causes increasing the tool overhang to reach a machined surface. A novelty in X-STREAM, a family of thermal shrink toolholders, is a series of slim design chucks to eliminate such a restriction. The new chucks follow Iscar’s coolant jet channel technology providing direct coolant supply to the tool cutting edge.
Changes in metalworking technology place new demands on cutting tools. To meet these demands, cutting tool manufacturers develop new products to assure increased performance. The industries’ response to the products sprouts new requirements.
Iscar’s NeoLogIQ campaign is based on new tools that were developed in accordance with customers’ input. You can expect more NeoLogIQ sequels to assure advanced machining in the new era of metalworking.
