ISCAR is launching IC5500 – a new MTCVD grade for drilling carbon and alloyed steel (ISO P). The new grade features a new multi-layer and special postcoating treatment to substantially prolong tool life and strengthen insert toughness, while improving operational reliability. The new grade will be available on square inserts that are used on DR drills: 3340386 SOMX 060304-DT IC5500, 3340385 SOMX 070305-DT IC5500, and 3340384 SOMT 09T306-DT IC5500. The inserts made from IC5500 are aimed for use only in the outer pocket of DR drills (the inner insert should be an IC908 or IC808 PVD coated insert). The upgraded IC5500 MTCVD coating enables improved toughness, chipping resistance and thermal crack resistance, while the combination of new coating and new treatment improves overall performance and process reliability. The coating includes a post coating treatment to reduce residual stresses and improve chipping resistance, Alpha Alumina to reduce crater wear and improve chipping resistance, a thick Al2O3 to improve thermal crack resistance and an intermediate layer to enhance adhesion between the Al2O3 and TiCN layer in the bonding area, improving peeling resistance. The TiCN layer improves flank wear resistance and the adhesion layer enhances adhesion with the substrate, preventing peeling during machining. IC5500 provides an excellent solution for alloy and carbon steel drilling.

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.

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.

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.

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.

To meet market demand, TaeguTec has released an expansion to the CHASE-4-FEED family – BLMP 04, 11 inserts and cutters. They are, smaller double-sided four corner BLMP 04 inserts for small and high feed machining applications. The smaller size inserts mean more inserts can be mounted to the same diameter cutters, which will greatly improve productivity over the existing BLMP 06 type under similar conditions. Available in Ø8(1z) and Ø10(2z) sizes, these are an alternative to solid end mills for roughing operations. While both the BLMP 11 and BLMP 13 cover a similar machining range, the BLMP 11 inserts give an advantage as they make it a finer pitch same diameter cutter for better productivity. The cutters come in all types, including face mill, end mill and modular types. While, as part of the new campaign, the design for the new CHASE-4- FEED line highlights TaeguTec’s

new direction, the new CHASE-4-FEED logo will be applied to the BLMP 06, 09 inserts and cutters as well.
