The use of high pressure coolant is growing as manufacturers seek ways to reduce cutting time, improve machining process reliability and achieve longer tool life. ISCAR’s new JHP tools with coolant channels provide all of these advantages. High-pressure coolant lowers temperature at the cutting zone and reduces – or even eliminates – built-up edge phenomenon, especially when machining stainless steel and high-temperature alloys.

Shorter chips are easily managed, as they do not tangle around the work piece or machine parts and so there is no need to stop the process frequently. With conventional cooling, the chips usually prevent the coolant from reaching the insert rake face in the cutting zone. However, the JHP tools coolant stream is directed precisely between the insert rake face and the flowing chips, which results in a much more reliable process as well as an improved surface finish and longer tool life.

With a growing demand for JHP tools, ISCAR has introduced new TTADR/L-JHP threading adapters with high pressure coolant channels carrying TTG DECAIQTHREAD 10-cornered inserts. The adapters are designed for use with standard MODULAR-GRIP MAH…- JHP holders.

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 enhance blade life and reduce running costs. All PCSAW bandsaws are operated through the on-board userfriendly 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 that 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 tailormade for all types of cutting conditions on all types of steels and profiles.

Robustness of Amada machinery, combined with longevity of Amada blades and a highly dedicated backup policy provide Amada customers, with total peace of mind.

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. Workpieces 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 shuttletype 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 motiondetector 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 workpieces, the bandsaws in the H series are equipped with a hydraulic full-stroke, dualvice clamping system.

For machines capable of cutting diameters greater than 700mm, the guide arm travels on linear guideways 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 antivibration 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 allowing workers to be deployed to more productive activities.

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 KASTO HIGHPERFORMANCE BAND SAW REDUCES CUTTING TIMES BY UP TO 50 PERCENT The fully automatic machine is optimised for bimetallic and carbide blades and can be applied in areas such as the steel trade, steel production, forging mills, machine manufacturing and the automotive industry. 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 a constant cutting force for excellent results with all materials.
