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.

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.

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.

No two customers’ needs are exactly alike. Finding the right solution means thoroughly understanding objectives and configuring a solution that matches them precisely. Our engineers have decades of industry experience which promote achieving specified goals with a process that fits and enhances a customer’s work flow. From the early beginnings of bandsaw machinery produced by Amada, (many of which are still running today), Amada has strived to offer machines that not only meet customers’ needs, but exceed them by offering features that were once considered impossible. The technology of the bandsaw demonstrates the ability and limitations of the blade. As blades advance in technology, so do the machines utilizing them. Amada, as a proud manufacturer of both the machines and the blades, continues to research these developments and incorporates customer feedback to produce constantly evolving solutions. Amada supplies bandsaw machinery and blades, such as the HK / HD series for mitre cutting, the semi-automatic H series, fully automatic HA / HFA series and the VM vertical series. The latest bandsaw technology is reflected in models such as the Dynasaw 430, the PCSAW with pulse cutting technology and CMB high speed circular saws. Some features include out of square cutting detection, motion detectors to monitor the blade for jamming or breakage while cutting and quick approach arms. Add to this no work limit switches and work lights, hydraulic blade tensioning, variable blade speed control, vice pressure control units and positively driven wire brushes. 9 times feed for cutting long lengths and cut-off counters ensure the correct number of cuts. All these features, assist semi-skilled workers in the operation of the machines. Certain models can be left to run unmanned on larger batch runs, thus allowing staff to do other important jobs at the same time. Take-up conveyors and tripod stands are available making material handling simple during the loading and cutting process. Models available start with the entry level of 250mm capacity, which are highly popular and favourably priced. With larger steel suppliers all utilizing Amada bandsaws daily, testimony is given to their accuracy, reliability and longevity. Cutting accuracies are obtained right down to 0,2mm. With such accuracies, the need for secondary machining processes is greatly reduced and in some cases eliminated. The latest additions to the Amada bandsaw range is the PCSAW, with either single pulse cutting action or double pulse cutting action. The PCSAW series is designed to offer high cutting rates, high precision, low noise and long blade life. Vibration has always been an unwanted characteristic of metal sawing when cutting too fast. It leads to decreased blade life, noise and uneven or inaccurate cutting. By introducing a controlled pulsating motion to the blade through either an induction motor or a servo motor, all unwanted vibrations are eliminated and most efficient metal cutting is achieved. Blade temperature is reduced considerably during the process, and this together with positive chip removal through a twin wire brush system and a large area chip conveyor all enhanceblade life and reduce running costs. All PCSAW bandsaws are operated through the on-board user-friendly CNC control. The HPSaw (High Performance Saw) is possibly the fastest bandsaw in its class with the latest in cutting speed innovation and the ability to cut at up to 1.5 times faster than the high speed circular saws. The specially designed AXCELA HP1 blade for this machine also reduces material wastage by up to 60% and guarantees accurate cutting. Circular sawing machines are the optimal technology for realizing reduction in cycle time and high-precision cutting needed for steel bar cutting at high speed. An automatic loading table for continued cutting operation is supported by a CNC powered cut-in control for ease of operation. In perfecting functionality of these machines, Amada has developed a unique carbide tip

circular blade that cuts cleanly, generating virtually no burrs. A full range of bi-metal bandsaw blades are produced by Amada to compliment machine technology. As mentioned previously, a bandsaw demonstrates the ability and limitations of a blade. This means th

at a machine is only as good as the blade being used. Amada blades have earned the reputation of extreme reliability and longevity. All blades are manufactured in Japan to the most

stringent quality standards and utilizing the latest in electron beam welding methods. These measures ensure that premature blade breakage is almost unheard of. The comprehensive range of blades available is tailor-made for all types of cutting conditions on all types of steels and profiles.
