Sandvik Coromant showcasing new paths to success in Stuttgart
At this year’s AMB exhibition (Stuttgart, 18-22 September), Sandvik Coromant intends to show how customers and partners can achieve significantly higher productivity levels, more flexible machining processes and more sustainable production under the strapline ‘Shaping the future together’. For instance, the global specialist in cutting tools and tooling systems will be revealing how it is revolutionizing the world of turning, improving the entire manufacturing process with digital connectivity solutions and offering fascinating possibilities for the automotive and aerospace industries .
On Stand E50 in Hall 1, Sandvik Coromant will present digital solutions designed for smarter machining and greater manufacturing efficiency. These innovations will include CoroPlus® ToolGuide, which provides fast and precise tool recommendations for the specific operation and material type, as well as CoroPlus® ToolLibrary, which enables users to integrate tool assemblies directly into their digital machining environment. Along with software that helps improve design and production planning, the company will showcase networked tool and process-control solutions.
Trade visitors can also discover the latest technologies in the fields of turning, milling and drilling at the 375 m2 stand. Included will be turning solutions such as CoroCut®QD for cutting with the Y axis. CoroCut ® QD uses the potential of modern turning centres and multi-tasking machines to guide the tool in the Y direction, positioning the upper side of the indexable insert parallel to the end of the blade. This capability enables faster feed speeds and the machining of longer overhangs without loss of stability.
Also being promoted at the show will be the PrimeTurning™ process for turning in all directions. Manufacturers in the automotive and aerospace industries, in particular, can benefit since PrimeTurning™ is extremely versatile. Indeed, the process is suitable for turning short, compact components, for longitudinal turning, and for machining contours and front-end geometries.
"We are looking forward to another great AMB because this trade show always offers an excellent opportunity to meet customers and partners personally in order to optimize future co-operation,” says Josse Coudré, General Manager Sales Area Central Europe at Sandvik Coromant. “We are proud to present our high-end solutions in Stuttgart, all of which are designed to help manufacturers become more efficient, productive and profitable."
Thanks to numerous co-operations with machine manufacturers, including being a co-exhibitor on the DMG Mori stand, solutions from Sandvik Coromant will be on display in many places around the exhibition. Sandvik Coromant is also one of the sponsors and speakers at the special two-day AMB show ‘Digital Way 2018 – Digital Paths in Production’.
The Sandvik Coromant service team will again support and advise customers before and during AMB. A five-man technical crew will be available one week before the start of the trade fair in Hall 5, Room 5.3.
PrimeTurning™ now accessible on multi-task machines and VTLs
Cutting tool and tooling system specialist Sandvik Coromant has unveiled a new range of CoroTurn® Prime multi-task and axial type tool holders to help machine shops implement the new PrimeTurning™ methodology, which enables turning in all directions. The introductions allow users to maximise the benefits of PrimeTurningon multi-task turn-mill centres and vertical turning lathes (VTLs). Complementing the company’s existing radial tool holders, Sandvik Coromant now has a complete offer for PrimeTurning operations.
One of the highlights of the range is the CoroTurn Prime Twin tool holder for multi-task machines. Both CoroTurn Prime A- and B-type inserts can be mounted together on Twin tool holders, allowing manufacturers to undertake roughing with a B-type insert before switching to finishing with an A-type insert, for example.
”Modern multi-task machines are intended for the complete machining of components but typically have a slow tool changing time, often around 15-20 seconds,” says Håkan Ericksson, Product Manager General Turning at Sandvik Coromant. ”As a result, the new Twin holder will save customers a considerable amount of time when changing tools.”
As a further advantage, B-axis machining on multi-task machines permits the operator to program the angle of the tool in precise increments. When the machine cuts using its B-axis, a lot of accessibility is created using neutral holders. In combination with streamlined operations, this delivers the potential for huge time saving and productivity increases to help manufacturers reduce tooling inventories and achieve competitive gains.
Six new multi-task tool holders are being introduced, which are mounted at a 45° angle for B-axis machining and can be used with either CoroTurn Prime A-type or B-type inserts. Options for multi-task machines include four tool holders (one-insert only) and two Twin tool holders (two inserts). The CoroTurn Prime Twin tool holder is available for use with Coromant Capto® C5 – C8 size.
A range of axial tool holders for vertical turning lathes is also part of the range, which means that Sandvik Coromant now has a complete offer for PrimeTurning: axial, radial and multi-task tool holders. In total, eight dedicated tool holders for axial mounting are being launched. This type of tool holder is compatible with most types of vertical lathes, and is available in Coromant Capto for use with either CoroTurn Prime A-type or B-type inserts.
Although PrimeTurning is applicable to the entire general turning area, machine shops with large batch sizes (automotive) are set to benefit most, as will those machining large components (aerospace), where there is a need to reduce tool changes, set-up time and production stops.
Ultimately, the all-directional PrimeTurning method and CoroTurn Prime tools will ensure that manufacturers can complete their turning operations in a much more efficient way. Compared with conventional turning, a 50-80% increase in productivity, along with 1.5–2 times more tool life, can be achieved.

Sandvik Coromant, a global leading supplier of cutting tools, tooling solutions and know-how to the metalworking industry, introduces RAL90, an innovative tool for machining aerospace components made of aluminium and aluminium alloys.
The new milling concept for machining operations on high-speed spindles has a high-strength tempered base body that increases tool flexural stiffness and natural frequency. Thanks to its high-speed stability, RAL90 allows manufacturers of challenging aero structure components made of aluminium copper, aluminium silicon, aluminium magnesium, aluminium zinc and aluminium lithium alloys to achieve excellent metal removal rates.
An optimally designed, high-precision insert seat with seat numbering ensures a maximum runout accuracy of 20 microns axially and 15 microns radially, a feed rate of 0.3 mm/tooth and cutting depths of up to 14 mm. In addition, RAL90 secures inserts with a specially engineered, high-strength screw (M4, 5.0 Nm tightening torque).
The new insert geometries with polished surfaces are designed for maximum metal removal rates during roughing and semi-finishing operations. To guarantee a defined chip formation in the recut, the inserts provide a double remote entering angle on the inner front side – ideal for linear and circular ramping without having to reduce the programmed feed rate. The inserts can be employed with nose radii (0.5, 0.8, 2.0, 2.5, 3.1, 4.0 and 5.0 mm) specified for the aerospace industry with no need to modify the cutter or alter programmed tool length.
RAL90 is prepared for minimum quantity lubrication and high-pressure coolant (with replaceable nozzles). As standard the tools are supplied with a balancing quality of G6,3 (at 24,000 rev/min) or, by customer request, of G2,5. Depending on diameter, speeds up to 35,000 rev/min are possible. RAL 90 is available with cylindrical shank, screw coupling, HSK63A holding and TDA interfaces.
2-3 times greater productivity against cemented carbide insert grades
CC6190, a new ceramic insert grade for CoroMill 490, promises increased productivity in cast iron and hardened steel due to the potential for higher cutting speeds.
Any manufacturer involved in automotive part machining or general engineering will benefit from the use of CoroMill 490 with CC6190 ceramic inserts. A superior performance and enhanced precision are assured in applications that include the milling of engine components such as valve bodies, crankshafts and gearbox housings.
Designed and manufactured by Sandvik Coromant, CC6190 offers 2-3 times higher productivity than cemented carbide grades, while the insert design with parallel land delivers exceptional surface quality. It is aimed at the medium-to-light roughing of grey cast iron components, as well as nodular cast iron and compacted graphite iron (CGI) parts.
Improved tool life
In finishing trials on a valve body made from SS0125 cast iron, quality requirements included a surface finish of 1.0 Ra and flatness of 0.03 mm. At identical cutting data, CoroMill 490 with CC6190 inserts achieved 40% greater tool life over a comparable competitor tool. Similarly, another test showed a 20% boost in tool life when roughing a workpiece manufactured from GG25 grey cast iron.
CoroMill® 177 ensures precision and high torque transfer in gear wheel machining
The CoroMill® 177 tangentially-mounted hob from Sandvik Coromant features a number of innovations designed to deliver greater productivity and tool life in gear wheel machining operations.
For instance, a unique new segment fixturing interface ensures cutter accuracy and rigidity to deliver greater stability during machining. The result is the ability to achieve aggressive cutting data without compromising process security or reliability.
Sandvik Coromant delivers greater productivity and tool life in gear wheel machining operations with CoroMill 177.
Four cutting edges
Designed for module range 10-18, CoroMill 177 features indexable carbide inserts with four cutting edges for roughing, semi-finishing and finishing operations. The tool is aimed at parts that include spur gears and helical gears found in gearboxes and transmissions for wind power and other heavy industry applications. It provides a good alternative to HSS hobs and disc cutters in operations where productivity is the focus.
Even against other indexable insert hobs, the robust design of CoroMill 177 allows higher cutting data (up to 50% more) compared with competitor tools, while modern carbide grades from Sandvik Coromant can handle a higher chip load to deliver a minimum 30% improvement in tool life.
In trials on a 36-tooth, module 16 planetary gear, CoroMill 177 exhibited 67% greater tool life over a comparable competitor tool at identical cutting data. Similarly, another trial on a module 18 planetary gear with 33 teeth, showed a 54% boost in productivity, primarily because the more robust design of CoroMill 177 allowed the feed rate to be increased.
Ultimately, the secure and stable insert seats offer a reliable performance with no sudden failures. Tools can be designed to accommodate finishing inserts for DIN 3972-2 profiles but also roughing inserts with protrusion. Insert mounting is both simple and precise – insert screws are positioned to be accessed easily and there are no inclined screw holes.
