Cut X wire EDM: One-size fits all

There are many wire EDM machines on the market. Some deliver faster processing speeds, while others are more accurate. Identifying the optimal wire EDM machine solution has, until now, been a trade-off because GF Machining Solutions says there has never really been a machine that does everything well.

According to GFMS, its CUT X series of machines bucks the trend. Developed and manufactured at the company’s Losone factory in Switzerland, these EDMs are available in two sizes: the CUT X 350 (with a maximum workpiece size of 800 x 550 x 250 mm) and the CUT X 500 (1050 x 700 x 250 mm). GFMS says the machines are extremely accurate because of a new thermal management system and optimised mechanics.

The machines maintain consistent thermal conditions via sealed cabinets and doors that ensure cold air containment within the workspace, as well as controlled air flow. By keeping heat sources away from the mechanics, CUT X models perform consistently without the ill effects of temperature fluctuation outside the machine.

Notably, the machine’s CNC collects data from an array of temperature and humidity sensors located inside and outside of the work area as a further contributor to ambient workspace conditions. The data drives an AI algorithm that predicts possible thermal deformations and compensates the positioning of the X, Y, U and V axes. This AI-driven compensation enables high-accuracy results, even with the environmental temperature fluctuations that are common during long cutting cycles.

New additively manufactured upper and lower heads increase the cutting speeds of CUT X machines. The heads reduce the distance between the guides and the part, creating improved accuracies during cut, while also increasing the amount of fluid that pushes through to optimise flushing and cutting speeds.

Mastercam agrees to acquire Cimquest

Sandvik is acquiring US company, Cimquest, which will become part of group company Mastercam, a specialist in CAM software. Cimquest is a Mastercam reseller located in New Jersey. The deal will add talent, technology and diversity to Mastercam’s ecosystem of solutions. Mastercam has no plans to change relationships with any external vendors, customers, or other resellers as a result of this agreement. Rob Hassold, owner of Cimquest, states, “We’re very excited to sign this agreement of acquisition with Mastercam and Sandvik. Joining the Mastercam team will enable us to continue to focus on what we do best: serving our customers.”

Making tools and fixtures on an ad hoc basis

Before vehicles are produced in large series, automotive manufacturers test and check the
properties and functions of all components under different conditions. All-Forming GmbH in
Kappel-Grafenhausen specialises in the production of the required prototypes and pilot
series. With innovative ideas and in-depth expertise, the team develops and fabricates the
necessary tools and fixtures. This is where the company appreciates the huge potential of
wire EDM technology.

To produce its punching and forming tools, the specialists at All-Forming have been using
the wire erosion process for many years. The company invested in a Mitsubishi MV2400R
Connect wire EDM machine in the middle of 2022 because the previous machine was
outdated in terms of programming and operation.
Production manager Sebastian Singler says All-Forming decided in favour of the wire EDM
machine from Mitsubishi Electric for several reasons. “First of all, the MV2400R Connect
comes with a cutting-edge and future-proof programming and operating approach. We
benefit from state-of-the-art touchscreen operation. In addition, interfaces to current CAM
systems are readily available. We also the like very large workspace which provides easy
access to the machine operator. This is particularly important for us as we frequently
machine one-off parts.”
All-Forming programs the components to be cut at a CADCAM workstation using the 3D CAD
workpiece data. The data for the NC program for wire EDM gets sent to the MV2400R
Connect via a direct data line. There, the company retrieves the current production orders
and NC programs and loads the machine with sheet metal accordingly.
The advantage is that the company can position several different pieces of sheet in the large
workspace. All-Forming’s MV2400R Connect can therefore cut several workpieces
overnight, unsupervised. This goes a long way towards producing stamping and forming
tools at short notice.

Vollmer set to unveil two eroding machines

At the GrindingHub 2024 exhibition in Stuttgart this May, Vollmer will give premieres to a
number of innovations. For instance, the company will unveil its QS 860 and QSF 860 eroding machines, which can machine PCD-tipped circular saws. Although the machines will not be on show in Stuttgart,
Vollmer will be providing information about them both digitally and in face-to-face
meetings. Another innovation from Vollmer will be the VFS 400 filtration system, seen for the first
time at GrindingHub. Visitors to the trade fair can experience live how the space-saving
system carries out ultra-fine filtration of cooling oil or dielectric during the sharpening
process. Depending on the machine type, up to two Vollmer sharpening machines can
connect to the VFS 400. At the show, these machines will be CHX 840 and CS 860 grinding
machines, which sharpen carbide-tipped circular saws. The VHybrid 260 grinding and eroding machine and the VLaser 370 laser machine will also be live on the Vollmer stand. Among further new technology will be a feature for the VGrind 360S grinding machine. Thanks to an optional dressing unit for the grinding wheel, tools with the ultra-hard cutting material PcBN can now also be ground in two machining steps: roughing and high-precision finishing. PcBN machining is possible with the VGrind 360S because the machine has very high system rigidity on one hand, and X, Y and Z axes driven by linear induction motors on the other, which implements oscillating tool machining. Vollmer will also showcase products and services from its subsidiaries Loroch and ultraTEC innovation.

More exhibitors and product diversity

The second edition of GrindingHub is set to open to grinding experts from all over the world
on 14-17 May 2024. Over 460 exhibitors from 31 countries will present their latest grinding
technology solutions in Stuttgart, now in four exhibitions halls for the first time.
The event will be about more than just technical products and innovations, as Dr Markus
Heering, managing director of organiser VDW (German Machine Tool Builders’ Association),
reports: “Automation and digitalisation, skills shortages, new customers and markets, and
the promotion of young talent: the industry is facing multiple challenges and opportunities.
As the meeting place for the grinding technology industry, we want to offer the community
a platform for swapping ideas and picking up information. I’m convinced we’ll succeed
thanks to the larger number of exhibitors, the impressive supporting programme, and wider
international and sectoral diversity.
