S33 – THE GOOD VALUE SOLUTION FOR INDIVIDUAL REQUIREMENTS

Universal and flexible are the features of the new S33 CNC universal cylindrical grinding machine from STUDER. It can grind small to large workpieces in single batch, small or large series and is available with centre distances of 400mm, 650mm, 1000mm, 1600mm and a centre height of 175mm. The changeover from grinding between centers to live spindle grinding takes place in record time. Complex workpieces are easily ground in just one clamping. The basis for the universal cylindrical grinding machine S33 is the machine bed made of solid Granitan® S103. Thanks to its favorable thermal behavior this offers a high degree of dimensional stability, while short-term temperature fluctuations are largely compensated for by the mineral casting. STUDER has redesigned the machine base geometry and supplemented it with an innovative machine base temperature control, which ensures fast and stable production. The mounting of the dressing unit on the double T-slot of the longitudinal slide massively reduces time needed for set-up or changeover of the machine. While the S33 is based on the STUDER T-Slide concept, which now features an extended X-axis stroke of 370mm, STUDER offers various wheelhead versions. The turret wheelhead with a 1° Hirth coupling and automatic swivel can accommodate up to two external and one internal grinding spindle and is equipped with the latest generation of contact detection. The external wheelhead with a grinding wheel right, can be manually set to 0°, 15° and 30°. The machine set-up and changeover costs can be reduced thanks to the turret wheelhead with multiple grinding wheels and the fast set-up software Quick-Set. The S33 can easily handle internal-, external- and face grinding in one clamping which leads to an even higher efficiency in complete machining. The C-Axis, with an option of either a direct or indirect measuring system, allows the grinding of forms and threads. The S33 can also be equipped with a chuck workhead, specially designed for grinding chuck parts. More than a hundred years of grinding experience is integrated in StuderWIN, which enables safe programming and efficient use. StuderTechnology requires just a few parameters to automatically calculate precise grinding parameters in just seconds. Good quality and a stable process is assured right from the beginning. The optional integrated modules such as StuderForm, StuderThread or StuderContourBasic extend the functionality of the machine. The hand-control device PCU makes it possible to set up the machine close to the grinding process. With electronic contact detection, downtimes can be reduced to a minimum. With the standardized loader interface, the S33 can also be automated.

The available shuttle table is fully electric and maintenance free; there are no hydraulic oils to handle and table changes are fast, smooth and energy-efficient. An optional lateral automatic scrap conveyor allows the removal of scrap pieces from the working area without the need to interrupt the cutting process. The sideways operation of the short conveyors allow for easy maintenance and trouble-free running. The Durma HDF/HDFL 3015 fiber machine achieves highest dynamics and fastest laser processing cycle times thanks to the combination of rigid mechanics and a state-of-the-art numerical control and drive system. Programmes can be loaded easily into the machine with a USB stick or over a fast Ethernet connection with the company network. In the high-pressure auto-focus cutting head for the fiber laser the cutting lens is shielded from the laser process by an exchangeable lowcost protection window. The 1μm wavelength light is very sensitive to dust or other contamination produced in the cutting or piercing process, therefore the cutting head is being well protected in an additional cover to ensure that all critical parts remain as clean as possible. The integrated capacitive distance sensor is capable of having the head follow height differences in the sheet even at the extreme high cutting speeds that can be achieved with the fiber laser technology, while stateof- the-art linear motors promote accuracy and increase productivity. The CAD/CAM software provided has all the tools to import or draw parts, prepare and optimize automatically different geometries for the laser cutting process and make efficient nests. The all-solid-state fiber laser technology reduces maintenance requirements, and offers the lowest possible running cost with a wallplug efficiency of 30% and without the need of any laser gas. When the application requires a broader spectrum of material types to be cut and the maximum thickness range is limited, the fiber laser is the ideal solution and it will cut faster at lower cost than any CO2 laser at the same laser power.

AMADA ENSIS 9KW/6KW FIBER LASER CUTTING MACHINE

ENSIS-3015AJ 9kW/6kWis designed for high-speed stable cutting over the entire range of machining, from thin to thick sheet metals, which has been made possible by the evolution of AMADA’s original beam control technology (ENSIS technology) and the expansion of oscillator output from the conventional 3kW to 9kW/6kW. High quality cutting over the thick material range is achieved by overcoming problems related to fiber lasers through reduced dross and bevel and improved surface roughness. NC equipment is provided with the AMNC 3i, which can be operated easily like a smartphone. It is adapted to AMADA IoT V-factory and visualizes machine operating results including power consumption and processing costs, contributing to performance. Furthermore, it enables smart manufacturing through maintenance and support to maximize machine capacity, as well as proposals to improve production efficiency. AMADA’s high-output oscillator provides for maximum output of 9kW/6kW to enable high-speed and high-quality cutting over the entire processing range (thin, medium thickness and thick sheet metals), based on energy saving and high-quality beams. ENSIS technology allows the laser beam to be controlled freely into the optimum beam form according to material quality and thickness. Additionally, the auto collimation mechanism is provided as a new feature. The variable range of the condensing diameter has been expanded greatly to achieve excellent stable cutting over the entire thickness range. Furthermore, combined with a high-output oscillator, the technology enables high-speed stable cutting of thick sheet metals, cutting with reduced dross and bevel and improved surface roughness. In addition to the new beam control technology, the fiber laser cutting machine employs Clean Fast Cut (CFC) technology and Easy Fast Cut (EZFC) technology to dramatically reduce the consumption of assist gas during nitrogen cutting, which is used mainly to cut stainless steel. It applies an original non-contact nozzle developed by AMADA that supplies assist gas at a low pressure to reduce processing costs, while maintaining cutting quality.

EVERISING FULLY AUTOMATIC BANDSAWS

Everising’s H series bandsaws are well-suited for heavy duty cutting applications as their column- type design allows for maximum cutting stability.

Everising has four pivot-type bandsaws in its S-250HB – S 460HB range. The bandsaws feature full PLC control of all electrical and hydraulic functions. The raising and lowering of the cutting head is controlled by a single lifting cylinder which makes for quick, efficient operation. Work-pieces are secured during cutting by a hydraulically controlled dual-vice clamping system. Blade tension, a factor that can extend the life of a blade, on Everising’s S machines is controlled hydraulically for optimal blade life. Blade speed is controlled by an inverter giving infinitely variable speeds of between 20 to 100 m/min. The machines also feature automatic shuttle-type feeding systems.

A pre-set counter shuts off the S Series bandsaws after a given number of items have been cut, while an idler-wheel motion-detector shuts down the machine should the blade stall or break. In addition, the saws detect when stock has run out and automatically shut down. In its column type H Series bandsaw range, Everising offers 11 different models. These range from the H-250HA with a 250mm cutting capacity to the large H-1100HANC capable of cutting workpieces of 1000mm x 1100mm dimension. The machines at the larger end of the range have progressively more features, such as the ability to use tungsten-carbide tipped blades. However, all of the H series bandsaws are well- suited for heavy duty cutting applications as their column type design allows for maximum cutting stability. Should the blade on an H series machine break, the machine will automatically shut down to protect both the operator and the machine. The bandsaws are fitted with automatic chip conveyors which keep the inside of the machine clean and save on operator time. In terms of the operator’s time, the H series are fitted with user-friendly NC touchscreen controls with a self- diagnostic control system. As with the S series, the H series’ hydraulic system and electrical devices are controlled by PLC. When there is need to cut bundles of steel rod, on the H series S-250B to the H-460 HB models, a hold-down device ensures that the material being cut stays secure in the machine thereby offering consistent quality. For larger work-pieces, the bandsaws in the H series are equipped with a hydraulic full-stroke, dual-vice clamping system. For machines capable of cutting diameters greater than 700mm, the guide arm travels on linear guide-ways for greater stability during cutting. On the larger H Series models, an anti-vibration roller not only eliminates vibration but extends blade life as well. The anti-vibration roller and the saw blade clamp are automatically adjusted. Optional H-Series devices feature an out-of-square detection system which automatically shuts the machine down while adjusting dual wire blade cleaning brushes which also serve to extend blade life. Everising’s automated functions allow for a minimum of skilled supervision.

GREAT FOR LARGER BATCH SIZES

Walter TC410 Advance thread formers

Walter presents its new TC410 Advance thread former With the TC410 Advance HSS-E thread former, Walter is rounding off its range of threading tools – and can now offer its customers more than 200 thread dimensions and tolerances. The TC410 Advance with TiN coating can be used universally for blind and through-hole threads (metric, metric fine, UNC/UNF and G), all formable materials from the ISO material groups P, M and N as well as for ISO K and S as a secondary application. In addition to the general advantages of thread formers as well as non-cutting machining (no wedging of the tool due to trapped chips consequently higher process reliability), Walter is primarily bringing economic benefits to the fore with the new tools. Decisive factors for this include the new geometry and special post-treatment. Innovative mould edges reduce the cutting time in the material. This reduces friction and consequently the amount of heat generated, which in turn reduces wear and ultimately increases the edge life of the tool. The post-treated, extremely smooth surface of the tool reduces the torque and additionally increases the tool life as a result. Walter offers the TC410 Advance in two variants. Without lubrication grooves or with lubrication grooves for deeper threads up to 3.5 × DN. The excellent price/performance ratio makes the TC410 Advance an attractive choice for users with medium to large batch sizes in particular. This is because it can produce more threads with the same tool.
