Automated loading options extended

Two new automatic loading developments for the large-capacity Helitronic Vision 400L grinder and two-in-one Vision Diamond 400L grinding/eroding machine have been announced by Walter Ewag: the Top-Loader and Robot Loader 25.

Top-Loader features a pneumatic swivel arm with gripper to integrate with Walter’s standard robot pallet system for tools up to 32 mm diameter. The two-pallet system, one each for blanks and finished tools, can each accommodate up to 500 tools (depending on size).
The Robot Loader 25, meanwhile, can accommodate 21 tools of up to 315 mm diameter and 25 kg in weight (or 28 tools of up to 220 mm diameter; 70 tools up to 105 mm diameter). Equipped with a Fanuc robot and featuring new software that accommodates the ‘random’ loading and storage of tools and blanks in HSK holders on up to seven pallets, the efficiency and effectiveness of the Robot Loader 25 is enhanced by laser marking for tool set-up and optional ‘diameter determination’ functionality for automatic operation.
Both the Walter Helitronic Vision 400L tool grinder and Helitronic Vision Diamond 400L can accommodate tools up to 315 mm diameter and 420 mm long. The latter can process (grind/erode) rotationally symmetrical precision tools in PCD, carbide, HSS, ceramic, cermet and CBN in a single set-up.

HMCs showcased

The stand of Starrag will centre on Heckert’s four-/five-axis horizontal machining centres, as well as on how the company’s Integrated Production System (IPS) is an integral part of Starrag’s Industry 4.0 strategies (hall 17, stand 530).

Heckert’s recently announced horizontal machine series offers traverse rates up to 80 m/min. The machines – H45, H50 and H55, L40, L50, L55 and X40 – not only have a smaller footprint of up to 30% less than traditional horizontal-spindle models, which results in an estimated 15% increase in productivity per unit area, but offer acceleration rates of 1.2 G, tool-change (chip-to-chip) times down to 2.2 seconds and pallet-change times down to 8.5 seconds. The latest Heckert HMCs are based on a modular design that enables the use of different pallets. In all cases there is an optional NC rotary table (up to 900 rpm) for turning operations in the same set-up. Different tool magazines are available up to 320 stations.

Multi-spindle turning on display

Tornos will give a UK exhibition debut to the MultiSwiss 8×26 (hall 19, stand 312). The machine is one of a family of three that range in spindle size from 14 to 32 mm. Equipped with eight spindles and eight slides for main operations, and accommodating up to three tools per slide, the MultiSwiss 8×26 features eight synchronous motor spindles and fast barrel indexing for producing turned parts up to 26 mm in diameter. Each of the 11 kW motor spindles is equipped with a C axis and counter spindle.

The counter spindle is mounted on two axes so it can work completely independently. Offering up to five tool positions, two of these provide the option of driven tools. A quick-change tool-holder system developed for MultiSwiss machines makes full use of kinematics that focus on keeping tools close to the workpiece, maximising in-cut time. Thanks to the damping performance when machining, Tornos says that the MultiSwiss can improve surface finish and extend tool life by an average of 30%, and up to 70% in some cases.

Fast-change pallet technology

Schunk will be giving a UK exhibition premiere to its new quick-change pallet modules at the show (hall 20, stand 180). The Vero-S NSE3 138 quick-change pallet module and Vero-S NSE-T3 138 tombstone module offer an optional spring-actuated cone seal that automatically locks the module’s changing interface as soon as the clamping pin is lifted.

Schunk’s Vero-S NSE3 delivers a pull-down force of 8 kN or, with activated turbo function, 28 kN. As a result, high tilting moments and transverse forces can be absorbed when parts are clamped at the base for machining their height, for example. Clamping and positioning of the modules is carried out via a short taper with a repeat accuracy of <0.005 mm. Due to the conical fitting, the clamping pins can also be joined into the modules eccentrically. For further information www.gb.schunk.com

16 machines on display

Mills CNC is set to showcase 16 Doosan lathes and machining centres (hall 18, stand 520).

In total, eight lathes will be on display, including the new 10”-chuck Puma 2600SY (sub-spindle, Y axis) Mk II, the recently launched 12”-chuck Puma GT 3100LM equipped with driven-tool capability, and the Puma V8300M VTL with driven tools and ATC. Eight Doosan machining centres will also be displayed: two five-axis machines; a large NHP4000 horizontal machining centre with a 60-tool magazine; one VC 3600 twin-table vertical machining centre; and four of Mills’ vertical machining centres from the DNM series, which includes the DNM 4000 that is making its UK debut at the exhibition.
