Horn has extended its circular interpolation system for slot milling to include tools for the production of narrower grooves. The exchangeable inserts are now offered in smaller cutting widths from 0.25mm to 1mm, depending on the diameter. Dependent also on tool diameter, the maximum milling depth is between 1.3mm and 14mm. Inserts are available with different coatings to suit the material being machined. Due to its mass, the solid carbide tool shank ensures vibration damping throughout the milling process. All variants of tool shank have an internal coolant supply. The circular milling system is fast, reliable, achieves good surface finish and offers users a host of advantages. During the process, the tool plunges into the material either at an angle or horizontally and may then be driven on a helical path. It means that threads, for example, can be manufactured to a high level of reproducible quality. When compared to machining using indexable inserts on larger diameters or solid carbide milling cutters for smaller diameters, circular interpolation milling is generally more economical. The cutters have a wealth of applications, as they are able to machine a wide range of materials including steels, titanium and superalloys. www.phorn.co.uk

Hi-Tech Machine Tools will also represent the Freddy Products family of industrial recycling vacuums and coolant filtration machines

Wet and dry machining “Maximum performance is achieved by using the latest coating technology – Alpha Ferro Platin X – a new high-performance coating. In addition, they have made it their mission to solve the problematic differences between wet and dry machining and have created specific experts where it is most important. Further to comprehensive technological updates, the eight new milling cutter types in the series also fit into the new H&V naming. These are: Performmaker (end mill cutter), Slotmaker (roughing cutter), Chipmaker (trochoidal cutter), Mirrormaker (finishing cutter), Formmaker (torus cutter), Blademaker (face torus cutter), Rowmaker (full radius cutter).”

“H&V’s success is based on innovation, a culture of togetherness, open interaction and many years of successful and trusting cooperation with its business partners. H&V focuses on permanent improvement and continuous development of its products, which is also reflected in its comprehensive product portfolio.”

“A Freddy coolant vacuum recycles your coolant so it can be reused, with filtration down to 5 microns. Sucking coolant straight from your machine tool slump, and returning it for reuse within seconds, it saves you time and increases coolant life – saving you money.”

Freddy Products “Recycling coolant has become increasingly important in recent decades, offering clients the chance to rid their workplace of contaminated metalworking fluids, whether they be synthetic, semi-synthetic or neat oils.”

“People working in manufacturing facilities (metalworking, milling and machining) that use these oil-based cutting fluids are exposed to the adverse health effects of contaminated fluids and oil mist. Machines used for production applications, such as screw machines and machining centers, centreless grinders, and CNC machines, create fine oil mist, which contains undisclosed additives that are harmful to human health. Ensuring an oil mist-free environment is highly crucial to safety and cleanliness in the workplace.”

“The variants include end mill cutters, torus cutters, full radius cutters, form cutters, chamfer cutters, roughing cutters, face torus cutters, finishing cutters and micro-cutters.”

“With innovation at its heart, milling cutter specialists, H&V Tooling is producing tooling today that will help shape the manufacturing world of today and tomorrow. Depending on the application, H&V designs and manufactures cutters for machining steel, cast iron, titanium, Inconel, aluminium, hardened steel, abrasive material, inox and stainless steel. The new EXN1 series was developed to enable potentially easily machinable materials to be safely processed and meet the specific requirements of non-ferrous material cutting.”

Hofmann & Vratny (H&V Tooling) a leading manufacturer of solid carbide milling cutters based near Munich, Bavaria, Germany and UK company Freddy, a manufacturer of industrial recycling vacuums and coolant filtration machines have both recently appointed Hi-Tech Machine Tools to market and service their products in South Africa.

“Their machines are well suited to companies currently not utilising a fluid recycling system that may be looking to reduce coolant consumption, prolong fluid life, reduce the health risks associated with poor fluid management and even improve machining performance by eradicating the use of contaminated coolant. Additional benefits include the potential to significantly reduce expensive fluid disposal costs, improve tool life and remove harmful contaminants that cause bacterial growth.”

“The company, which was established in 1976, originally manufactured carbide profile milling tools to machine plastic for the eyewear industry. Now it is renowned for its solid carbide milling cutters, which it only started manufacturing in 1989. With a team of almost 100 employees, the company produces around 1.6 million tools in 7 000 variants every year.”

“All the international manufacturers that we now represent are the leaders in their particular aspect of the market. They also cooperate and work with each other in advancing the technology for their particular product. This is why we are proud to be associated with H&V Tooling and market their products in South Africa,” said Chris Killian, Sales Manager of Hi-Tech Machine Tools.

“Hi-Tech Machine Tools represents Mazak CNC equipment, Albrecht precision chucks, hyperMILL software, Blaser Swisslube cutting and grinding fluids, 5th Axis workholding fixtures and Fraisa SA, a family-owned business that offers its customers a complete range of endmills, drills and taps.”

Tooling manufacturer, Horn has introduced a new carbide insert grade, SG66, for turning components from steel that has been case hardened to 58 HRC.

“Whether you are using fully synthetic, semi-synthetic or neat oil, contaminated metalworking fluids are detrimental to your health, the environment and business. Reducing the effectiveness, and reducing the life of machine tools can be costly. The finish of your products can be diminished, not to mention the health and safety implications that can be caused by the contaminated coolant, such as skin irritation, rashes and dermatitis. Then there is the cost of purchasing and disposing of your metalworking fluid.”

When compared to machining using indexable inserts on larger diameters or solid carbide milling cutters for smaller diameters, circular interpolation milling is generally more economical. The cutters have a wealth of applications, as they are able to machine a wide range of materials including steels, titanium and superalloys.

The NeoMill-Alu-QBig indexable insert milling cutter from Mapal stands for top performance in high-volume milling of aluminium. The tool manufacturer thus offers a very economical solution for use on high-performance machines, such as those found primarily in the aerospace industry.

The exchangeable inserts are now offered in smaller cutting widths from 0.25mm to 1mm, depending on the diameter. Dependent also on tool diameter, the maximum milling depth is between 1.3mm and 14mm.

Walter has now launched its new X·treme Evo Plus drill from the DC180 Supreme product family that is now available up to 8XD for the first time.

“Machine coolant never really wears out. Machine coolants and cutting oils become unusable when they become excessively contaminated with bacteria, tramp oil, metal fines, or wastes.”

ANT Industries, a leading manufacturer of aero engine and gas turbine components in Atherstone, Warwickshire, has announced a significant milestone in its commitment to quality and excellence.

“However, the company is constantly developing new products. The EXPK1 series has been developed specially for cutting steel and cast iron. The steel and cast iron material group is a challenging one for milling tools to handle, not least because of the variety of alloys that can be used and all the different properties they have. On the one hand, the tools need to be able to withstand huge amounts of strain, for example due to the high tensile strength of steel (up to 1400 N/mm2) and the unequal structure of cast iron. Yet on the other hand, very soft alloys require geometries that are favourable for cutting in order to ensure that the material can be machined effectively.”
