Leader extends zero-point offering with Mate

Following a recent partnership agreement, the full range of high-precision zero-point fixtures from Mate Precision Technologies is now available in the UK exclusively from work-holding and machining efficiency specialist Leader Chuck International.

Being one of the latest players to enter the zero-point fixture market, Mate Precision Technologies was all too aware of the need to bring significant advantages over the competition when it launched its next-generation Dyno range.Consisting of DynoGrip vices, DynoLock base plates and DynoMount tombstones, the ethos behind the range stems from Mate targeting manufacturing efficiencies within its own workshop. With areputation for producing high-quality punch-press and press-brake tooling for manufacturers across the globe, the company employs around 300 highly skilled staff at it manufacturing facility in Minnesota, USA. So the need for machining efficiency gains comes from worldwide competition.

Extensive trials of the previous generation zero-point systems, available from established suppliers, under real life production operations, highlighted a number of limitations that Mate addressed with its new products.

Leader Chuck’s managing director Mark Jones explains: “With Mate’s extensive knowledge of the high-quality tool steels and fine tolerances used to produce its tools for sheet metalworking, it’s only logical that the same materials and processes are used for the Dyno range of fixtures. It’s why the company offers a ‘zero wear out forever’ policy across the range with a 100% unconditional customer satisfaction guarantee.”

Mate DynoGrip self-centring vices, for example, shorten set-up time and reduce process variability. Two zero-point four-stud engagement patterns are available, 52 and 96 mm, which are compatible with other systems or can mount directly to the machine table via toe clamps or bolted through the body.

DMG Mori Medical Days

DMG Mori will stage a Medical Days event later this week (8-9 March) at its Medical Excellence Centre in Wernau, Germany, which opened last year. The machine tool manufacturer will present new technologies to help the medical sector meet increasing challenges in the global market. In addition to the symposium, the company will run live demonstrations on a variety of machining platforms, with the accent on turning. These demonstrations will include an NLX 2500 SY/700 with Robo2Go automation and an NLX 2500/700 SY with MATRIS robot loading.

Pallet changer zeros in on productivity and accuracy

Building upon the company’s existing comprehensive range of zero-point clamping systems, Zimmer Group is expanding the series with the launch of its new pallet-changer technology. In addition to changing pallets in machine tools, this system also opens up numerous other applications, such as the handling of components using robots while maintaining high levels of repeatability.

The slim design and low set-up profile of the clamping plate and clamping pallets, allow both close-proximity pallet loading on the machine table and optimum use of the space within the machine. High clamping forces create arigid system, while the retaining forces enable high torque levels, together with a high-precision connection between the robot and the clamping plate to make the handling of heavier pallets, in particular, easier and safer.

The structural design of the pallet changer means that system clamping takes place without the need for pneumatic pressure. However, it is possible to increase the clamping forces further by using Zimmer’s Plus connection, which provides pneumatic assistance. In addition to four rotation locks for pallet coupling, the system features an integrated blow-out or cleaning function that prevents dirt or liquid from collecting in the pin holder, contact surface and rotation locks.

Notably, the pallet coupling is used as a pallet interface for the product and creates the connection to the clamping pallet. The rotation lock enables backlash-free positioning of the bearings when joining with the product, whilesensors for piston position and clamping position verify safe operation. All functions are controllable directly via the pneumatic connections on the sides. There is also the option to control the unit by means of alternative connections on the bottom of the product.

Ergonomic bicycle assembly boosts productivity

At Rose Bikes in Bocholt, 120 different bicycle and e-bike models weighing between 5 and 28 kg are ergonomically manufactured on six flow lines with the help of flexible Bike Promobil assembly carts produced by Roemheld. The result of a joint development project between the two German companies, the cart is now available worldwide, including in the UKand Ireland through Roemheld UK.

A shortage of potential employees in the Bocholt area, near the Dutch border, prompted family-run Rose to look for a production solution to meet increasing demand for its products. Instead of producing on a conveyor belt, as is the case with other bicycle manufacturers, Rose chose the flow line option when it opened its new factory in 2020.

Stefan Strauss, production manager at Rose, says: “The conveyor belt is too inflexible and tends to stress employees. Flow line production is much more operator friendly, so it’s easier to find new staff and train them. Work should be fun. We don’t have anyone watching with a stopwatch and staff take turns at different stations to maintain their interest.”

Strauss originally wanted to design and build an assembly aid himself, but did not have enough time. So in 2020, Roemheld offered an early version of the cart, but it was too big, heavy, inflexible and expensive. A development partnership took shape to address these issues. One elegant idea was to hold the bike not by gripping on the frame but by placing an insert into the seat tube. Adapter sleeves accommodate different tube diameters on the various bike models, making the clamping process universal across the whole range. Rose Bikes now has 130 Bike Promobil assembly carts from Roemheld.

Floyd Automaticgets a grip on small components

Now available in the UK from Floyd Automatic Tooling is the expanded range of MASA Microconic over-grip spindle collets. The precise and stable clamping of small workpieces in the sub-spindle of sliding-head machines has long been an issue for turned part manufacturers; MASA says it has revolutionised this ‘pain-point’ for manufacturers to deliver precision work-holding operations.

Until now, this solution has been available primarily on 20 and 32mm capacity sliding-head machines. However, MASA is now expanding the series to cater for manufacturers working on 10 and 12mm diameter capacity models.

To truly understand Microconic, manufacturers must first consider that only three things are in physical contact with the workpiece, the cutting tool, coolant/cutting fluid and workholding. MASA’s Microconic over-grip collet system ultimately allows manufacturers to rethink what is possible. This work-holding system consists of a cartridge and precision collet. The over-grip collet fits inside a cartridge and allows accurate adjustment before fitting directly into the existing collet sleeve with no machine adaptations required.

The patented over-grip collets can open up to 4mm larger than the clamping diameter and can also incorporate an ejection guide sleeve blank, which helps the end user to solve the difficulty of ejecting parts from the collets after machining. This allows manufacturers to reach behind flanges, parts with heads or any other enlarged feature.

Suitable for processing components with stepped features such as connectors, screws or other common parts, the over-clamp system can clamp over the protruding features and securely clamp on the main body of components. The collets are available with clamping diameters from 0.2 to 10mm, offering concentricity of 3-5µm.
