Alliance Tooling invests in Kafo machine

Alliance Tooling, an injection mould toolmaker based in Leicester, has added a new Kafo machining centre to its manufacturing facility. This latest acquisition marks the fourth Kafo machining centre purchased by Alliance Tooling, underscoring the company’s ongoing commitment to technological advancement and quality in the manufacture of graphite electrodes for mould making. Kafo machining centres are supplied and serviced by TDT Machine Tools.

Specifically tailored for the efficient production of graphite electrodes, Alliance Tooling’s new Kafo SCV-5 machining centre offers agility and a compact design, while also boasting a custom dust extraction device that guarantees the containment of particles during operation. This feature is instrumental in maintaining a high standard of cleanliness at Alliance Tooling, ensuring a safer and cleaner working environment.

New micro-cutting technology installed

Nanoker from Spain specialises in technical ceramics and advanced nano-composites for various extreme applications. Now, the company is pushing boundaries using micro-waterjet technology. After winning a tender from CERN, Nanoker scanned the market for a suitable machine system. After a thorough evaluation they decided for a NCM 10 micro machine from Water Jet Sweden. The first challenge was to win the tender, second to find and select the right machine, and third to implement the new technology into its own production flow.

For every new set of parts, the machine needs to fine-tuning to get perpendicular cuts with tolerances of ±0.02 mm. Measuring the perpendicularity of machines after installation is standard procedure at Water Jet Sweden. However, for the NCM 10 Micro machine, laser measurement and ball bar verification also take place.

Water Jet Sweden always finalises training at the customer’s site, making sure the customer gets up and running. The company stays until after the customer produces a series of approved parts.

Sergio Rivera, product and business development manager at Nanoker Research, sums up the project: “The micro-water jet machine enables access to a very precise technology that cuts very hard materials in ‘close-to’ 2D geometries. Apart from the business related to the ‘big science’ industry, the machine will present new avenues for us to produce parts according to customer specifications with a different machining strategy.

He adds: “This technology will also allow us to access other markets, such as industrial. Previously, the production of ‘close-to’ 2D geometries in hard ceramics were limited to electrically conductive materials by using wireEDM. Now however, thanks to micro waterjet, we can machine both electrically and non-electrically conductive materials.”

Lantek delivers major productivity gains

Australian laser subcontractor Online Laser can manufacture twice as much as before with the help of Lantek’s sheet metal CADCAM and ERP software. Based in Bendigo, Victoria, the company has two Bystronic Bystar fibre lasers and previously used a proprietary software system, which is now no longer supported, to manage the machines and the workflow through its factory.

Ben Harris, programming and production manager, says: “We were looking for an end-to-end system to manage our quotations, programming and production. With our old system there was no integration and we had to repeatedly enter the same information.”

Online Laser installed the Lantek system in July 2019 comprising Lantek Expert CADCAM, MES, Integra and WOS. This year it added the Lantek Opentalk connection directly to the laser machines so that validation of the status of the machines and the parts being manufactured is automatic.

“The vast majority of parts come as CAD models in several different formats, and we can import them directly into the Lantek software,” says Harris. “The integrated Lantek Expert can quickly analyse the laser cutting times and – within the Integra software – combine them with subcontract costs such as folding, powder coating or machining to produce an accurate price for the whole job. Previously this could have taken a few days, now it can be done in 1-2 hours and sometimes in minutes.”

Where the material type and thickness are the same, the company nests parts from different customers in the same sheet.

“The inventory system is worth the investment on its own,” states Harris. “We can manage remnants of material to use them up and keep track of stocks so that we don’t suddenly run out of material.”

Kerfs cuts bottleneck at subcontractor

As a subcontract manufacturer, Q-Laser offers laser, waterjet, press brake and fabrication services throughout the UK. When the main division at Washington, Tyne & Wear, realised its waterjet cutting department based in nearby Hebburn was reaching full capacity, the company needed a solution. Kerf Developments provided the answer with a Semyx Optima 420 twin abrasive waterjet cutter.

Founded in 2012, Q-Laser set up its waterjet cutting division in 2019 to complement its laser, press brake and fabrication services, starting with a five-axis waterjet machine. Except for the pandemic, the waterjet division has grown exponentially, and the existing waterjet machine was struggling to meet the capacity demands of the business, so Q-Laser turned to the Optima 420 twin abrasive waterjet.

With two cutting heads, the 4 x 2 m bed machine instantly doubled cutting capacity in comparison to the company’s existing machine. In a sector where clients expect a quotation in hours and components cut and delivered in less than a week, the addition of the machine has alleviated the bottleneck, created additional capacity and immediately reduced lead times.

Company director Colin Hewitt says: “We gave Kerf a range of trial parts. The productivity, precision, cut quality and edge finishes were beyond anything else we had seen, so our decision to invest was made. A few months after the installation, Kerf has excelled in its service and consumable supply, which was a critical element for us. Kerf stocks all spare parts for the machine in the UK and they are available on a next-day service. This gives us complete confidence.”
