Small investment with a big effect

In keeping with its company slogan of ‘Small investment – big effect’, Buchen, Germany-based rotary table manufacturer Weiss GmbH brought eight machine tools ‘up to speed’ with the help of clamping devices from Hainbuch.

“We had to reduce set-up and idle times through optimised precision and shorter machining time, and felt that Hainbuch could support us in this endeavour,” says director of tool management Thomas Schuster.
Together with Hainbuch, the existing clamping programme of conventional three-jaw chucks was promptly analysed and appropriate alternatives were found. The result was the introduction of customised clamping devices for the eight machines.
Hainbuch’s Toplus clamping system (pictured) was implemented to ensure optimal precision with high clamping forces, while the Centrotex quick-change system was also integrated into the manufacturing process to facilitate the rapid change-over of numerous component types.
The large transport cams manufactured by Weiss are soft machined with indexable-insert tools. Viktor Gruslak, acting department manager responsible for cam milling, says: “With the old fixtures we had set-up times of between 2-3 hours for a complete conversion. Now, the overall time is between 10 to 20 minutes. That is a huge saving.”
Asked whether clamping device providers other than Hainbuch were contacted, Schuster says: “At that time, we were extremely thorough in looking over the offerings from all possible vendors, but the Hainbuch solution was the best suited to our parts.”

Momentum builds to METALTECH 2018

The 24th edition of MetalTech is set to take place on 23-26 May at Putra World Trade Centre in Kuala Lumpur, Malaysia.

More than 2000 companies from 33 countries will participate, showcasing hundreds of machine-tool systems and products revolving around this year’s theme of Industry 4.0 and smart manufacturing.
Like many other advanced countries, Malaysia’s manufacturing industry is undergoing a period of rapid transformation, implementing robotic assembly lines and computer controlled processes. As a result, a number of exhibitors are also showcasing complete assembly line systems, rather than individual machine tools. In addition, visitors will be treated to an opportunity to learn from industry heavyweights through the new live demonstration arena on the show floor, where ‘smartphone manufacturing processes’ will be the theme.

Lightweight bending tools simplify set up

The manual installation of upper tools in bending machines can be difficult and time-consuming as the tools themselves are heavy.

By the same token, heavy tools can also be a health and safety concern, especially if the job has multiple different bending requirements.
With new, patented lightweight tools from Trumpf, these problems no longer apply. The tools are over 30% lighter than the previous generation of Trumpf tools and, indeed, claim to be the lightest on the market.
All of the new tools up to 300 mm in length are also fitted with the Trumpf Safety-Click mechanism. As a result, the physical effort involved in installing the tools is considerably reduced which, in turn, leads to shorter set-up times.
These new additions to the Trumpf range are included in the new bending tool catalogue, which is available by email request from tooling@uk.trumpf.com or as a PDF download from the company’s website. As well detailing all the products in the range, the publication includes several tips and tricks from Trumpf bending experts.

Press brake will make aero parts

LVD says it has been awarded an order from Japanese technology company, Kawasaki Heavy Industries (KHI), via sales agent Itochu Machine-Technos Corp, for its Synchro-Form adaptive bending technology.

The KHI order is for a custom-built, 1000-ton class of Synchro-Form press brake equipped with special tooling to produce large panels for commercial aircraft fuselage structures. Forming such large components to a desired contour is a challenging task and one that will be simplified with Synchro-Form, which maintains angular consistency and the required geometric profile, says LVD. The machine also enables in-process automatic quality control when handling, positioning and bending large parts with multiple bends.
KHI is a key production partner for the Boeing 777X, the successor to Boeing’s popular 777 aircraft. Boeing says that the 777X will be the largest and most efficient twin-engine jet in the world.
LVD’s Synchro-Form press brake meets the tight tolerance requirements demanded of the KHI application and the need for complete automation. The order was awarded to LVD after several bending trials where strict accuracy measurements were satisfied. LVD says that the Synchro-Form press brake will be manufactured at its production facility in Belgium.

Tools feature magnetic safety system

Mate has expanded its press-brake tooling line with the introduction of American Precision Style tools featuring the new patent-pending Maglock magnetic safety system. Compatible with press-brake laser and optical safety systems, this full line of punches and dies is designed for press brakes configured with American-style holders and available in lengths from ½” to 18”.

Maglock uses rare-earth magnets to attach and seat the punch to the holder with no separation between the surfaces. The magnets are specifically and proportionally added along the punch shoulder so that the ‘up force’ of the magnet is localised and directed at the contact surface of the punch holder.
Safe and reliable, installation of a Maglock punch always results in the shoulder seating on to the holder, says Mate. The strong yet balanced Maglock connection is also said to simplify lateral (left or right) position adjustments. Once the punches are seated in the desired position, the holder clamping system must be engaged. Maglock does not claim to be and is not intended to be a replacement for the holder clamping system.
Unlike punches with mechanical designs (buttons, springs or pins) that become unsafe to use if the mechanism is damaged or missing, Maglock’s non-mechanical concept works safely all the time. Mate punches with Maglock offer additional safety if electrical, hydraulic or pneumatic power to the brake is cut off or damaged. In lengths over 4”, the design includes a lever to facilitate punch removal.
The reversible/symmetrical punch tang design enables the punch to be installed facing forward or backward.
