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 Durma HDF/HDFL 3015 fiber laser machine features a rigid stress-relieved welded steel frame construction with a stiff gantry axis system moving the cutting head. Highly accurate parts even when cutting with fastest speeds and under highest accelerations are guaranteed. An integrated shuttle table maximizes productivity and minimizes material handling times. The shuttle table and pallet change system allows convenient loading of new sheets or unloading of finished parts, while the machine is cutting another sheet inside the working area. 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.

In a market where skilled artisans are becoming more and more scarce, it has become necessary to look at alternative ways of machining, whether it be for general engineering, tool-making or production work CNC machining is quicker and certainly more accurate than conventional milling machines and there is no need for constant monitoring while in use. Taking this into account, MJH Machine Tools have a solution to suit customers’ needs. Featuring an entry level CNC control, our Ctek CNC milling machine is the first step to CNC machining. As long as the operator has basic knowledge on using a DRO, he can, within a few hours, be taught how to program and run the machine. There is no need for G code knowledge as the control is conversational, using a question and answer format. The software is simple to use with graphic input in basic machinist language. The control has options for standard operation modes such as drill, tap, bore, contour and pocket programming, which is ideally suited to general engineering work without a need for external programming packages. The latest Ctek’s come with linear guides on all three axes for better accuracy and speed, as well as a direct spindle drive motor and an improved Z axis motor with inline break which eliminates the need for a counterbalance. The Ctek can be fitted with a 4th axis within a matter of hours and programmed from the standard Ctek control.

The Ctek range has six x-travel sizes, 800mm, 1 000mm, 1 500mm, 1 800mm, 2 000mm and 2 500mm. These machines are available in open type or fully enclosed depending on the customer’s requirements. All spares are available ex stock at a fraction of the cost compared to other controls. With hundreds of these machines sold throughout South Africa since 1997, it is not surprising that Ctek CNC milling machines have been the first step to full CNC machining in many workshops. Should there be a requirement for a high performance machining centre for super fine finishing and accuracy, the Akira Seiki is the machine to consider. Spindle power ranging from 15HP on the Junior series to 42HP on the Super Vertical range and spindle speeds from 9 000rpm to 15 000rpm guarantee high quality surface finish.

Walter presents the new HU5 geometry for ISO M and S materials With the new single-sided indexable inserts with HU5 geometry, Walter has the answer to one of its users’ key questions: How can more components be produced using the same number of machines? In comparison to the indexable inserts that can be used on both sides, the HU5 has a larger contact surface to the tool holder. This increases the stability and allows for greater cutting depths, feeds and a larger metal removal rate – specifically, in the practical test, this comes to 18.36 l/h instead of 10.71 l/h. In addition to the stable fit, the decisive factor behind this is the combination of the geometry and Walter Tiger·tec® Silver cutting tool materials. This allows for increases in tool life of up to 75 percent. The geometry itself has been specially developed for heavy roughing of stainless steels and high-temperature alloys. It is typically used for applications in the oil and gas industry, e.g. for large valves made from AISI 316 material, or in the aerospace industry with Inconel 718 or titanium materials. The main cutting edge, which is protected by a negative chamfer, prevents fractures when machining hard edge zones and optimises the performance for hard scale, e.g. of forged parts. Components with interrupted cuts and other demanding machining operations are equally feasible. The curved cutting edge and a deep chip breaker groove produce low cutting forces with high feed rates, consequently reducing the machining temperature. The variable rake angle in the area of the corner radius allows for soft chip reforming and increases the tool life. Available in the standard basic shapes of CNMM, DNMM and SNMM, Walter rounds off its vast product range in the areas ISO S and M with the HU5 geometry. As a result, Walter now offers a total of 12 geometries in six grades as well as tools with precision cooling and ceramic or CBN inserts.

Depending on requirement, users can choose between manually operated, semi and fully automatic variants – and of late, also between different cutting ranges. To achieve this, KASTO is extending the range by three further models. The KASTOmicut is designed for cutting tubes, sections and solid materials to length and for mitre cutting. Workshop operators benefit particularly from the high cutting accuracy and quality with different materials and the attractive price-performance ratio of the saws. In 2016, KASTO presented the first models of the new series with a cutting range of 260mm for round material and 310 x 260mm for flat material.

Users can choose between the manually operated base model KASTOmicut P 2.6, the KASTOmicut E 2.6 with hydraulically controlled saw feed, the semi-automatic KASTOmicut U 2.6 with hydraulic material clamping and the fully automatic variant, the KASTOmicut A 2.6. With its intelligent accessories, this enables efficient, extensively unattended operation. Newly incorporated into the portfolio, KASTO now has two models with a larger cutting range: Die KASTOmicut E 4.6 saws round material up to 335mm diameter and flat material with dimensions up to 460 x 335mm. It is specially designed for single- sided mitre angles and is suitable for cuts from 0 to +60 degrees. The saw has a hydraulically controlled feed. Blade and material tensioning is carried out mechanically. The cutting speed can be continuously adjusted between 20 and 110 metres per minute. This opens up a wide range of possibilities for the user with different material qualities. With the KASTOmicut U 4.6, users can even process flat material up to 520mm wide. With this saw, the material is also clamped by means of a horizontal hydraulic vice. This simplifies handling and increases the output in the case of small batches. The continuously adjustable cutting speed lies between 12 and 150 metres per minute.

Like the smaller models of the KASTOmicut range, mitre cuts from -45 to +60 degrees are possible. The mitre angle can also be continuously adjusted. A heavy and torsionally rigid welded structure for the saw frame provides extremely stable support for the saw blade, ensuring excellent cutting quality even with hard-to-machine materials. KASTO has extended the range with the addition of the KASTOmicut P 1.8. The saw has a cutting range of up to 180mm and is likewise suitable for straight and mitre cuts from 0 to +45 degrees. It features manual material clamping by means of an easy- tooperate and easily adjustable clamping device. The saw blade is also tensioned manually. The feed rate is determined by manually guiding the saw frame and a cutting rail serves as material support. An efficient three-phase motor delivers a drive power of up to 1.5 kW and ensures high cutting quality. Like other models in the KASTOmicut range, the saw also scores with its small dimensions and excellent accessibility. It can be easily picked up by a lift truck or forklift and positioned as needed. Depending on the design, the shortest possible cutting length is six to ten millimetres and with a remnant piece length of 15 to 30mm for individual cuts, users can make maximum use of the material to be sawn. A highly efficient worm gear mechanism provides top performance and the sophisticated design ensures.

Milling cutters with corner radius introduced to the Walter Perform product range With the launch of the new MC232 Perform solid carbide milling cutters, Walter is both rounding off its portfolio of products and opening up new possibilities. For the first time, the Tübingen-based tool specialists are bringing a milling cutter with a corner radius and reduced neck to the market as part of Walter’s costeffective Perform product range. The Walter range in the MC232 Perform family now includes solid carbide cutters with or without a reduced neck and with or without a corner radius in a total of 126 dimensions, of 2–20mm in diameter. The milling cutters can be used for all typical milling applications (lateral milling, full slotting, pocket milling, helical plunging, ramping) and are suitable for a variety of materials and milling strategies. Solid carbide milling cutters with corner radii meet an important demand of the market. This is because the corner radius allows the user to better approach individual component geometries. It also improves the tool life of the milling cutter, as the edge stability is increased. The reduced neck in turn makes the milling cutter more flexible, as the user can use it with an even wider variety of cutting depths. Other features of the Perform line have been adopted – for example, the high level of cost efficiency for small and medium batch sizes, or Walter’s own WJ30ED grade, which provides a high level of wear resistance. ISO P materials are the primary application of the MC232 Perform, with ISO M and ISO K as secondary applications. The new milling cutters are likely to be of particular interest to job shops and manufacturers with frequently changing orders or quantities.
