How to optimise base-plate removal from 3D-printed parts

Stirling-based CA Models, a specialist in high-quality, fast-turnaround metal and plastic additive manufacturing, is using new investment in two wire-erosion machines from Sodi-Tech EDM to optimise the process of removing 3D-printed parts from their build platforms.

“We had two Sodick wire EDM machines that were still running well but getting on in years,” explains founder and managing director Clark Campbell. “I felt it was the right time to bring in some new technology for the next decade. The new Sodick machines are even more accurate and faster. At CA Models we are in the ‘quick’ business, where just about every client wants their parts yesterday. That’s why we need an in-house resource when it comes to wire erosion. Every time we have a really complex, accurate part to produce, the clock is ticking.”

He adds: “I think Sodick technology is brilliant and the reliability of the machines warrants some loyalty in my opinion,” says Mr Campbell. “I went to an open day at Sodi-Tech EDM’s Warwick facility and was really impressed with the latest machines, which will play their part in a big way over the coming years.”

Installed in September 2022, the new Sodick ALC600G and ALC800G wire EDM machines are already busy.

“For example, take a titanium build platform with 14 motorsport parts on the base,” says Mr Campbell. “When the printing process is complete, the entire platform goes into our furnace for heat treatment for 24 hours, after which we wire-off all the components from base plate using our Sodick technology. As the wire cuts so finely we do not lose any dimensional accuracy in the parts. Furthermore, the machines wire so quickly that we get a head start in finishing the components.”

Aerospace supplier appoints new engineering director

Aerospace supplier Erodex UK has appointed Damian Ward as its new engineering director. Ward has more than 20 years’ experience providing tooling and engineering solutions within the aerospace industry and joins from Matrix Tooling Solutions, where he was business development manager. Prior to this, he held the role of aerospace business manager at Seco Tools.

Within his role as engineering director, Ward will be responsible for engineering operations at the company’s West Midlands based graphite machining facility, driving efficiency gains and reducing cost by implementing engineering best practice via the latest tooling, work-holding and software solutions.

“Erodex are the leading supplier of graphites, EDM consumables and state-of-the-art graphite machining to the UK aerospace industry, with a very capable and experienced engineering team,” says Ward. “I see further developing the engineering operations as a really exciting opportunity. We have a fantastic team, have benefited from continued investment in the latest five-axis CNC machine tools, and have a clear direction for investment moving forward.”

Ward’s introduction follows the previous appointment of James Kirk in 2019 as group operations director, with the two now working closely to drive the company’s continuous improvement programme.

Erodex director Steve Rolinson says: “These are exciting times for Erodex. Our goal is to expand and increase our presence within emerging overseas markets such as Latin America. By increasing engineering efficiencies, we can be more competitive in these markets while reinforcing our leading position within the UK aerospace sector. We’re delighted to welcome Damian to the company and look forward to seeing the benefit that his wealth of tooling and engineering expertise will bring.”

VHybrid from Vollmer offers ultimate flexibility

Among the latest innovations presented at the recent GrindingHub exhibition, the new VHybrid from Vollmer was one of the talking points of the show. With the facility to both erode PCD and grind carbide cutting tools in a single operation by combining the two technologies into a single machine, the VHybrid is the epitome of flexibility.

To celebrate the arrival of this innovation and develop a greater understanding of the concept, Alexander Schmid, product manager for rotary and PCD tools at Vollmer, discusses the new arrival in more depth.

“We started with two technologies, disc and wire erosion technology,” he says. “With this technology, we have significant success processing tools via erosion. The concept for the new VHybrid machine is borne out of the successful VGrind technology. This means that we have vertical spindle alignment with the upper spindle being the grinding spindle, and the lower spindle having both erosion and grinding. With this functionality, we can erode and grind most of the tooling that is available on the market. Furthermore, as the use of complex tools such as full-head PCD tools is steadily increasing, the demand for machines that enable combined machining, eroding and grinding, is also growing.”

The concept of the VHybrid 260 offers the user the possibility to erode 100% but also to grind 100%. This is a decisive advantage as both technologies are available for use on the same tool. But the machine offers many further benefits besides.

“For instance, the generator in the VHybrid machine is the most powerful in an erosion machine on the market right now,” says Schmid. “We have received feedback from the market that our system is the benchmark in terms of efficiency and surface finish.”

Wire EDM upgrade: fit for the future

A series of upgrades for GF Machining Solutions’ wire EDM machines will future-proof their performance, says the company. The upgrades relate to the CUT C, E and P wire EDM ranges, increasing their productivity, functionality, autonomy and process reliability.

For instance, with the Turbo Tech upgrade, customers can improve their processes and achieve higher quality and productivity. By applying the upgrade, the machine is provided with an additional technology priorities option – a compromise between speed and accuracy – in good or bad flushing conditions. Productivity can increase from 10% to 40%, depending on the geometry of the part and the flushing conditions experienced.

If customers need additional functionality they can enhance their machines with the Taper Expert upgrade (pictured), which enables the machining of large taper parts.

Customers can also increase the autonomy of their machines. One example is the big spool upgrade (up to 25 kg wire), which ensures longer process continuity with no need for constant wire changes.

In addition, users can take advantage of GF Machining Solutions’ rConnect platform, which comprises three digital services: rConnect Customer Cockpit, rConnect Live Remote Assistance and rConnect Messenger. With the ultra-secure hotline, rConnect Live Remote Assistance, customers benefit from the personal support of GF Machining Solutions’ qualified experts, while the rConnect Messenger app allows them to gain remote access to their machines and receive status updates on their mobile devices.

Thanks to the recently developed Seamless Support, a new module in Live Remote Assistance, customers are able to generate their service requests or ask questions about applications directly from their control system.
