HORN: New Cassette Holders for S224 Grooving System

New Axial Cassette System S224

HORN has expanded its range of face grooving products with new cassette variants for the S224 Grooving System.


HORN has extended its modular concept so that various types of cartridge can be clamped using a single base holder. The high coolant pressure ensures improved chip removal from the groove. Thanks to the wide range of chipbreaker geometries and substrates available with the S224 double-edged system, the tool system can be easily adapted to the machining task as well as the material to be machined.

KURT: 45-Degree Pyramid Workholding Bundles

NEW 45-Degree Pyramid Workholding Bundles With Standard Kurt Vises For 5 Axis Machining.

The Kurt platform was so well received by the machining industry in 2019, that they have developed a pre-engineered pyramid platform which is standard and accommodates 12 different vise models. These convenient configurations come bundled with the 45-degree pyramid along with 3 Kurt vises ready for mounting to machine table and handle parts from 2” up to 7”.

The Kurt pyramid workholding bundles facilitate clamping of three individual components in one fixture and completed in a single setup. And provide maximum access to all machined surfaces and allows for enhanced spindle and cutting tool clearance.

Kurt vises matched for the pyramid include self-centering and dovetail models: HP420, HP420C, HP420D, HP440, HP440C, HP440D, HP460, HP460C, HP460D, SCMX250, SCMX425, DTR20. Each bundle package comes complete with 45-degree pyramid, 3 vises mounted, and optional base plate for final mounting on machine table. Options include soft jaws for machining odd shaped profiles into the jaws, hard jaws, and a riser base model for even more part clearance.

HORN: S224 Face Grooving System

New Addition – S224 Face Grooving System

Paul Horn GmbH in Tübingen has expanded its range of face grooving products. To accommodate axial grooving operations with diameters ranging from 38 mm to 1,000 mm, Horn is now offering new holder variants for the S224 grooving system. Horn is extending its modular concept so that various types of cartridge can be clamped using a single base holder.

The internal coolant supply allows direct cooling in the contact zone while simultaneously increasing tool life. In addition, the high coolant pressure ensures improved chip removal from the groove. Thanks to the wide range of chip breaker geometries and substrates available with the S224 double-edged system, the tool system can be easily adapted to the machining task as well as the material to be machined.

Horn offers the axial holders in the following versions: LAK (left, external), RAK (right, external), LIK (left, internal) and RIK (right, internal). The maximum groove depth (tmax) is 14 mm. Groove widths (w) range from 3 mm to 6 mm. The internal coolant supply is via a transfer point on the base holder. However, the cartridges can also be used on older Horn holders without coolant transfer.

MecWash: Technology Meets Chemistry

Technology Meets Chemistry – Why Having the Right Balance is Critical for Component Cleaning

When it comes to the cleaning of engineered components it’s often considered that the physical washing machine is the only important part of the process. Cleaning additives and detergents are merely a supporting element.

For MecWash, one of the leading innovators and manufacturers of aqueous parts cleaning systems, the approach has to be about three crucial elements: the technology, the chemistry and the product that is being cleaned.

“It’s quite easy for a company to go out and acquire a washing system without understanding the importance not only of the chemicals required, but the impact they can have on the substrate of the component being cleaned,” according to John Pattison, Managing Director of MecWash based in Tewkesbury, Gloucestershire.

“It’s not just about knowing what contaminants have to be removed. The combination of an intense washing system with an inappropriate mix of chemicals and detergents could damage the substrate and lead to the cleaned component’s failure.”

MecWash has invested heavily in its own laboratory at its headquarters to develop, design and formulating chemicals for common and bespoke component cleaning applications.

So how does the process work?

MecWash works with a customer to understand the type of components being cleaned and what results are required. Analysis and trials then allows the correct wash process and chemistry to be defined.

The process begins with an audit of the customer’s cleaning requirements. This is thorough and covers key areas including:

  • The substrate of the components being cleaned
  • Are the components metallic, non-metallic or hybrid?
  • What is the type of contamination?
  • Do the components need to be brightened as well as cleaned?
  • Are the components as cast, machined, polished or a combination?
  • The geometry of the components and critical features
  • What is the cleanliness specification?
  • What is the process directly before the wash process?
  • What is the process directly after the wash process?
  • Does the component need to have any long-term corrosion protection after the wash process?
  • What is the size and weight of the components?

 Physical analysis is also undertaken. This includes:

  • Chemical compatibility with substrate
  • Removal of contamination from the component’s surface
  • Removal of the contamination from the process solutions
  • Millipore testing
  • Gravimetric analysis
  • Surface energy tests (eg water break)
  • Visual inspection or bespoke tests.

“The process is intense and thorough. It has to be to ensure the complete system and process will remove the contaminants to the highest levels possible without damaging the components during or after the washing process,” said Mr Pattison.

“It could take days or months, depending on the type of product or process and the end results required by our client and their customers. Manufacturers in the aerospace, automotive, fluid power and medical sectors are ever more demanding.”

Adapting to a client’s needs

MecWash continues to work with a client long after a chemical solution has been identified.

“We have to work hand-in-hand with a client as their products can change, or the manufactured make-up of the product could alter,” added Mr Pattison.

“Our customers are dynamic in their approach to manufacturing and we have a flexible approach in order to continuously optimize their processes, even if the machine has been on site for several years.”

New processes and technology

Changing processes and new technology has seen the washing process change over the years. The design of the washing systems and the evolution of chemicals has increased the ability of such systems to remove contaminants to a fraction of what they were capable of 10 or 20 years ago.

Hellerman Tyton is one of MecWash’s customers who have benefited from the skilled work of the laboratory team.

The cable management solutions specialist now achieves high quality component cleaning, within strict temperature constraints.

The company uses a MecWash Midi wash system with an integrated Aqua-Save waste water recycling system at its production centre in Devon. The cleaning system has been configured to wash a temperature sensitive plastic component, while avoiding the risk of product shrinkage.

Lina Ficken, Engineer Team Leader, at Hellerman Tyton, said: “It’s important that, following the expansion process, mouldings are comprehensively cleaned before further handling and assembly processes, not least to remove a silicone coating used during the manufacturing process.

“Our customers apply the cable protection systems on site via the application of heat which shrinks them into position – temperature is clearly a factor that needs to be tightly controlled during manufacturing,” she adds.

“MecWash have been able to configure the cleaning system so that wash temperatures are held at no more than 40°C, which in conjunction with the tailored AC33 chemical solution that the company was able to develop for us, ensures that all material leaves the cleaning process in the optimum condition.”

John Pattison of MecWash added: “MecWash worked closely with the Hellerman Tyton team for many months, developing the AC33 chemical, which is formulated to clean the plastic components effectively at low temperatures.

“MecWash’s expertise in wash chemistry is based on years of designing tailored chemicals for the most testing wash challenges for individual customers, as well as manufacturing our own range of general wash chemicals and inhibitors.”
