Features

CAD/CAM Software

OPEN MIND Technologies AG (Needham, MA) recently released hyperMILL® 2019.1 with a range of new features and enhancements including greater blending capabilities, 3D-optimized roughing & finishing, global fitting, rotational abilities for CAD electrode applications - and virtual machining simulation. Developed with Industry 4.0 in mind, hyperMILL® VIRTUAL Machining enables constant real time bi-directional communication between the machine tool controller and a remote hyperMILL® VIRTUAL Machining simulation, significantly improving manufacturing workflow.

Two new functions in hyperMILL® for 3D Z-level Shape Finishing will result in reduced programming time and improved milling. These include an “Automatic Face Extension” capability that can be used during programming to extend the selected milling surfaces, eliminating the need to modify the milling faces in the CAD system beforehand. Barrel cutters (in addition to general, tangential and conical barrel cutters) can also now be used for 3D Z-level Shape Finishing. 3D Optimized Roughing has also been enhanced, to ensure that multiple allowances are taken into account when free tool geometries are used.

5-Axis Vertical Machining Center

Mitsui Seiki's new Vertex 100 5-axis vertical machining center has been engineered to fulfill manufacturers’ demands for a compact, high-speed machine capable of high-precision milling of larger parts such as blisks for aircraft engines. The Vertex 100 can machine workpieces 1,250 mm in diameter and 850 mm tall while occupying only 3 m × 4.2 m of shop floor space. X-Y-Z axis strokes are 1000 mm, 900 mm, and 750 mm respectively. Maximum swing diameter is 1480 mm.

From CAT 40 to HSK-A100 taper sizes the Vertex 100 is supplied with multiple spindle options (15,000 rpm, 25,000 rpm and 30,000 rpm). A large 60-tool standard automatic tool changer handles maximum tool lengths of 300 mm and maximum tool diameters of 125 mm (CAT40/HSK A 63) or 160 mm (CAT 50/ HSK A 100), offering maximum flexibility for job shop applications. Larger capacity tool changers are an additional option. The machine's tilt/rotary table, designed and built by Mitsui Seiki and supported by the rigid and robust cast iron base, provides high precision and rotation speed up to 100 rpm. The table's C-axis motors are direct drive while the A-axis has tandem direct drive motors. The machine is capable of workpieces up to 1250 mm (49.25") diameter.

Scan System

SCANLAB GmbH (Puchheim, Germany) has announced series production of its high-end excelli-SCAN scan system. This premium scan head has proved its suitability for reliable industrial deployment in series micro-machining and has now itself gone into series production. Last but not least, the scan head's built-in intelligence predestines it for integration in automated fabrication environments that leverage Industry 4.0 and IoT (internet of things).

The scan system features novel SCANahead servo control as well as galvanometer scanners with highly precise digital angle sensors. And its built-in intelligence can be compared to autonomous driving – the scan head autonomously calculates its own control parameters and anticipates in real time for optimal navigation of curves. This servo innovation breaks through the irreconcilability between higher dynamics and maximum precision, thus providing an appreciable productivity boost to users. Additionally, contour fidelity is substantially improved at high marking speeds, e.g. when traversing sharp corners and circles. Control is furnished as standard by the powerful RTC 6 control board, now available as an Ethernet variant.

Hybrid Press Brake

Cincinnati Incorporated (CI) (Harrison, OH), a U.S.-based, build-to-order machine tool manufacturer, will introduce a 150-ton version of a new hybrid model. New features found on this press brake are an ergonomic sliding overhead control arm, unique built in storage cabinets, LED lighting, protective cylinder covers and side and rear guards. Cl's CIberlink generates daily log files of machine production with the ability to monitor machine status in real time on a desktop dashboard.

This hybrid press brake brings the advantages of servomotor pump technology to CI's existing lineup of hydraulic and electric drive press brakes. Unlike fixed-speed induction motors that drive the pump in conventional hydraulic systems, the servo-motor driven pump only runs during the working portion of the stroke, conserving energy while the ram is stationary. Ram speed of 550 ipm and precision ram repeatability of +/-.0002" assure fast and consistent production. The generous 14" stroke and 21" open height tackle challenging part shapes and tool heights.

AGD Group 1 Digital Indicators

The L.S. Starrett Company (Athol, MA) has introduced a range of Digital Electronic Indicators conforming to true AGD (American Gage Design) Group 1 dimensions, providing the ability to replace traditional mechanical indicating applications in the smallest AGD size specification class. Starrett 2700 Electronic Indicators are the first digital gages to match true AGD Group 1 dimensions (1.70"/ 43mm diameter).

Gages feature a .400" (10mm) travel, accuracy of ± .0001" (0.002mm) on the F2715 models and accuracy of ± .0002" (0.004mm) on the F2714 models. The gages can store and view 200 readings internally. Stored readings can be downloaded with included software and a USB style cable. Starrett 2700 Digital Indicators have a CR2032 cell long-life battery that can last up to 3,000 hours under typical use. Gages are output-compatible for SPC documentation via cable or wirelessly using a Starrett DataSure® Data Collection device. Switchable resolutions are .001/ .0005/ .0001/ .00005 or .001/ .0005/ .0001 in inch. In metric readouts, switchable resolutions are 0.02/ 0.01/ 0.002/ 0.001 or 0.02/ 0.01/ 0.002 mm.

Gear Grinding Platform

Norton I Saint-Gobain Abrasives, one of the world's largest abrasives manufacturers, announced the introduction of its new Norton Xtrimium™ range of gear solutions designed for high performance gear grinding in extreme, tight tolerance environments. Highlighting the new range is an innovative dual-worm wheel design that enables two operations in one grinding wheel. Norton Xtrimium Dual-Worm Grinding Wheels feature a unique design with a high-performance vitrified bond section for grinding and a fine-grit resin section for polishing the gear teeth, enabling one wheel to perform what traditionally required two wheels. In addition, improved surface finishes of Rz = 1.0 mm and Rpk = 0.05 mm, and reduced harmonics (noise) are realized.
