Makino unveils UPX600 high-precision wire EDM

At JIMTOF 2022 in November, Makino gave the public its first view of the company’s new UPX600 wire EDM for high-precision applications such as press dies,precision electronic parts and motor components. Features include a new machining power supply (EW200B), independent upper and lower machine drive control, and constant temperature control technology. The machine also contributes to the reduction of running costs by reducing the number of processing steps.

With the new EW200B machining power supply and machining conditions, it is possible to improve the optimum surface roughness, reduce the number of machining passes, and shorten the machining time by outputting electric discharge finely and efficiently during finish-machining.

Responsiveness is also a key feature of the machine thanks to a structure that allows independent movement of the upper head (Z/U/V axes) and lower head (X/Y axes).

By improving insulation, the rise time to the target voltage is shortened, enabling efficient micro-fabrication. Moreover, the three-sided elevating processing tank means operators can access the work area from three directions. As the machining tank descends below the top surface of the table, it is possible to work on the lower part of the workpiece. Even if the core is accidentally dropped, it can be easily retrieved.

The machine’s Hyper-i control offers intuitive operations with an efficient interface consisting of three categories: program, set-up and operation. The high-resolution 24-inch touchscreen feels like a tablet device.

Among the machine’s main specifications are: 650 x 500 x 320 mm travel in the X, Y and Z axes; ±350 x ±250 mm in the U and V axes; a maximum workpiece size of 1030 x 800 × 300 mm (width x depth x height); and a maximum payload of 1800 kg.

Protolabs launches 3D printing DFM analysis

Protolabs has launched DFM (design for manufacture) analysis for 3D-printed parts, offering peace of mind to manufacturers across Europe.It is a significant advancement to the offer as it provides added assurance that a part is suitable for 3D printing before committing to production, all entirely online in a matter of seconds.Andrea Landoni, Protolabs EMEA’s 3D-printing product manager, says: “The system will instantly highlight all the issues to the user, whether they are critical, such as parts that are too large, or non-critical, like dimensions that are close to certain thresholds like wall thickness and may not form completely.”

Machine tool production rising

The VDW (German Machine Tool Builders’ Association) is expecting production in the machine tool industry to grow by 9% this year, to a volume of €15.5bn. In nominal terms, this is only 10% below the record result of 2018. At its annual press conference in Frankfurt, Franz-Xaver Bernhard, VDW chairman, said: “We have largely overcome the effects of the pandemic. The industry has entered the current year with a significant backlog of orders.”

He continued:“Even though the gap between orders and sales is currently closing, the German Federal Statistical Office is still reporting a 12-month backlog of orders for the machine tool industry. This means that companies are well placed to weather any dip in orders in the first half of 2023, as suggested by the most recent figures.”

Vollmer’s VPortal goes live for customers

Through its new customer portal, VPortal, sharpening specialistVollmeris providing exclusive access to digital services, including its spare parts shop, machine overviews and technical documentation. Furthermore, VPortal gives customers the chance to send the support team any questions they may have about machines or services from Vollmer. Anyone who owns a Vollmer sharpening machine can register for and use the customer portal free of charge. Customers can request their unique log-in via e-mail or telephone.

“Our customer portal, VPortal, is the digital and personalised window that we provide to our customers and which we use to expand our services,” explains Jürgen Hauger, CEO of the Vollmer Group. “It forms the perfect link between the real and digital world, enabling our customers to keep a constant overview of their Vollmer grinding and erosion machines.”

The VPortal grants customers 24/7 access to their digital machine pool purchased from Vollmer. Notably, the digital service is available in English and German, and is free to use. At present, customers from Germany can register via e-mail or telephone. Once logged in to the online portal, the user can see a complete overview of the Vollmer sharpening machines available.

From the start page, the customer portal shows a clear overview of all digital services spread across five tiles: My machines, Spare parts, Orders, Support requests and Contact. Users can click on these tiles to navigate the portal and view or download the data that is most relevant to their Vollmer machines, as well as documents about technology or operation. When it comes to maintenance and servicing, VPortal enables users to submit an individual support request or to access Vollmer’s online spare parts shop.

Walter completes range of rough-turning inserts

With the new HU3, HU5 and HU7 geometries, Walter is completing its range of indexable turning inserts for heavy-duty roughing operations. The ‘H’ designation is for negative, single-sided and therefore highly stable inserts, standing for ‘Heavy (roughing)’, while the ‘U’ refers to universal use. Each of the three new geometries has specific features making them suitable for different applications.

The HU7 geometry for steel and cast-iron workpieces is the most stable turning indexable insert in Walter’s product range. It has a straight cutting edge while the negative protective edge chamfer ensures its suitability for use at high feed rates with depths of cut up to 17 mm. According to Walter, HU7 demonstrates excellent stability and is suitable for large-volume machining, even in difficult conditions, including the machining of forged parts or interrupted cutting operations.

Compared with HU7, HU5 geometry incorporates a curved cutting edge and an open chip-breaker groove design that provides a slightly softer cutting action to reduce cutting pressure and cutting forces. HU5 is therefore the first choice insert wherever heat generation and/or vibration occur. The grade is particularly suitable for the rough turning of high-temperature alloys and stainless steel.

The third insert design, the HU3 geometry with V-shaped chip formation optimises chip breaking even at small depths of cut and fluctuating material removal rates. This feature makes the HU3 suited to machining parts with a forged skin or varying surfaces. HU3 is primarily for use on steel materials with depths of cut from as low as 0.8mm, while maintaining chip control.

All three turning insert geometries are coated with the new Tiger•tec Gold grades, WPP10G, WPP20G and the WPP30G.
