Kennametal has released the FIX8 heavy-duty turning system, delivering maximum metal removal rates in steel, stainless steel and cast iron. With eight cutting edges per insert, the system increases productivity of any heavy-duty turning operation, providing the lowest cost per edge while reducing cutting forces up to 15 percent.
“FIX8 is designed to cover a wide range of applications, including turning and facing, smooth surfaces, interrupted, and heavily interrupted cuts. From medium depth-of-cut to roughing in steels, cast iron and challenging materials like stainless steel, FIX8 handles it all. Even extreme feed rates of up to 1.4 mm (0.055") and depths of cut up to 12 mm (0.472") are possible with FIX8,” says Matthew Fuerst, product manager, Kennametal.
The tangential design of the FIX8 insert features a rigid clamping system that pulls the insert securely into the pocket seat, offering suitable stability that enables the insert to withstand large cutting forces and vibrations for optimal performance. The insert is also supported by a replaceable carbide shim, protecting the pocket against deformation and damage.
The FIX8 tool holder features precision 3D coolant technology, supplying sufficient coolant precisely where needed. Three coolant nozzles are directed to the rake face, controlling temperature, chip evacuation, and supporting chip formation. Coolant exit holes in two different locations are directed toward the flank of the insert, controlling the heat in the cutting zone and prolonging tool life.

Southern Gear Adds precision measurement resources
Southern Gear is meeting customer requirements for the precise measurement of increasingly complex cylindrical and bevel gears with two advanced new Keyence Image Dimension Measurement Systems, capable of measuring up to 300 dimensions on as many as 100 parts in just seconds.
Dimensional measurement with conventional instruments and measurement tools is typically a slow, tedious process requiring the setup and adjustment of multiple complex fixtures — a process that’s heavily dependent on highly trained operators to achieve accurate and consistent results. With the new Keyence IM-8000 systems, setup and operation is greatly simplified and highly automated. For example, there is no time-consuming part positioning work or datum setup required. The simple “place-and-press” operation ensures consistent measurement of hundreds of dimensions on multiple parts with just the push of a button and regardless of operator skill.
“These new systems seem tailor-made for the complex precision parts we’re producing today for customers across the widest spectrum of applications,” says Southern Gear President Karen Malin. “We’re working to speed throughput in every facet of our operation; these new systems are taking significant time and effort out of these increasingly important operations.”
The addition of the Keyence systems is part of a multi-million dollar, company-wide investment in new technologies, methodologies and processes that, over the last several years, has, according to Malin, added much needed capacity to Southern Gear’s vertically-integrated shop floor.

SMW Autoblok Introduces KNCS-2G Power Chuck
SMW Autoblok has recently introduced the flexible, fully Proofline sealed KNCS-2G power chuck that allows users to change jaws in under one minute — reducing downtime during changeovers which saves companies both time and money.
Ideal for lathe and mill-turn applications where frequent part changes are prevalent, the KNCS-2G features an optimized lubrication system with additional channels and grease pockets that are integrated into the jaw guideways to allow the chuck to operate for three shifts before additional lubrication is needed. The sealing and lubrication system makes the KNCS-2G suitable for mass production and ensures constant clamp force and extended life.
The chamfered guideways of the KNCS-2G are designed to allow for quick-change of jaws, making it flexible for operations needing multiple jaw changes and setups. The fully Proofline sealed chuck body and base jaws also provide additional protection against chips, lubricants and other debris.
The chuck body and internal parts are case hardened for increased chuck life and highest rigidity, precision and durability. The KNCS-2G is interchangeable with the standard KNCS-N chucks and existing master jaws can still be used without sealing. Sizes are available in 170–630 mm.

WFL Millturn Offers Heavyweight Machining Benefits
Higher, faster, further — as the saying goes, but now there’s “longer, wider, heavier.” Industrial requirements are constantly being pushed upwards. All of which means that WFL is entering exciting territory: heavyweight machining. The machining of large and very heavy components is often an extremely laborious undertaking that involves significant costs. Maximum process reliability and, above all, time savings in a component’s throughput time are the name of the game.
Combining all machining and measuring operations into a single Millturn complete machining center from WFL massively increases the efficiency of manufacturing. The unique Millturn machine concept and turning-boring-milling unit with gearbox offers precise chipping performance.
Gas and steam turbines or components for wind turbines, rollers, crankshafts and transmission parts in machine construction — can now be machined by WFL. A Millturn can even easily handle high-strength steel or HRSA (heat resistant super alloy) material.
A Millturn eliminates the need for tedious changeover processes. Warpage-free and secure clamping is critical for premium quality standards. Large masses have a tendency to deform or change simply as a result of their net weight. The sag of a turbine shaft weighing 60 tonnes is so great that this needs to be taken into account when clamping the workpiece.
This variable can be compensated with the correct design of the clamping device and clamping method. FEM calculation (finite element method) can be used to precisely determine how the workpiece can be correctly clamped and supported. In this case, WFL uses a rolling or hydrostatic steady rest depending on the characteristics of the workpiece. This ensures optimal machining quality and production. The accessibility to the machine with folding grate elements and tread plates also ensures the best possible ergonomics.
What’s more, the enclosed working area enables machining under high coolant pressures. The UHPC pump (Ultra High Pressure Coolant) can be used to reach up to 200 bar. This ensures an optimum tool life even with high machining parameters.
Flexible measurement technologies support the user and once again clearly highlight the benefits of measuring components with large dimensions. WFL measuring cycles are carefully considered down to the last detail. For example, special calibration methods using the measuring probe and temperature compensation — which is particularly important when working with large diameters — allow the expansion of the material to be taken into account. The WFL measurement methods can even be used to produce a workpiece with maximum precision in adverse production conditions (e.g., external influences such as temperature).
It is also possible to precisely measure the position of the workpiece in the working area. This is necessary to precisely manufacture extremely narrow shape and position tolerances, for example, fir tree profile slots or locating holes.
The CrashGuard Studio programming software also supports an effortless review of the machining program. This makes it possible to minimize production errors ahead of time.

LK Metrology Software Update Inspects Gears Automatically
Coordinate measuring machine (CMM) manufacturer LK Metrology has introduced a third release of its CAMIO 2021 programming and measurement software featuring numerous improvements. The most significant is the inclusion of a module that automates the inspection of spur and helical involute gears.
CAMIO GEARS makes it possible to begin measuring the specific geometry of gears quickly by using the core capabilities of CAMIO software to generate straightforward inspection programs, advanced gear reports and automated probe calibration routines.
For each gear type, the software has a unique set of definitions, evaluation algorithms and reporting graphics conveniently packaged in one add-on module, making it easy for users to bring a new capability to their existing CMM. The module supports alignment of the gear axis during measurement using any of the three CMM axes and traditional touch trigger probes or advanced scanning probes.
Several other improvements have been incorporated into CAMIO 2021 R3. Smart 3-2-1 datum alignment is new functionality that intelligently selects the datum axis and origin constraints, as well as the most suitable datum features using best-practice techniques. Should the user change the alignment properties manually, the selections automatically update.
Explorer Tree Datum Definition allows datum features to be defined more efficiently directly from the feature explorer, with the option of specifying the datum label. Report Table Feature Order provides new options for controlling the order in which features are reported in graphical tables, either alphabetically, by program output or in a user-defined order.
Teach-path coordinates and directions may now be defined using the CAD model. The GD&T (geometric dimensioning and tolerancing) reporting algorithm has been further enhanced to be independent of the standard used. Finally, there is new capability for retrieving points from a feature measured using a tactile probe, complementing existing functionality for retrieving data from a point cloud.
For CAD users, exchange file versions are compatible with the latest release of Spatial’s InterOp, as was the case in the previous iteration of CAMIO 2021. The interoperability software is an industry leader in CAD data translation that enables users to import, interact with, share and export 3D data easily across CMM platforms and manufacturing sites.
CAMIO 2021 R3 encourages novice as well as experienced users to drive the inspection process graphically from the CAD model, either online or offline, although teach-and-learn using the CMM handbox is available. An advanced user interface makes part alignment, feature inspection and dimensional tolerancing fast and intuitive.
The virtual CMM programming environment means that accurate axis movement and probe motion sequences may be simulated for collision detection and cycle time estimations. Help Files now use a version of HTML5 help that supports modern internet browsers, such as Microsoft Edge and Google Chrome, and link to locally installed help pages.
CAMIO 2021 supports Metrology Gate, Industry 4.0 software that enables production teams to view and analyze quality data and monitor all CMM activity remotely from any internet-connected device. The web-based portal provides 24/7 access to information from any enabled metrology device for automatically retrieving inspection results and a summary of errors, a record of program changes, uptime of the CMMs and OEE (overall equipment effectiveness).
Historical logs assist troubleshooting and warn when routine maintenance is due, not only of the inspection machines but also of the machine tools or other equipment on which the components are being made. The software provides a modular solution for various levels of CMM automation to raise productivity, cost effectiveness and product quality.
