First infinitely reusable manufacturing mould

Fyous is launching the world’s first infinitely reusable moulding technology, known as PolyMorphic moulding, at this week’s RAPID + TCT event in Los Angeles. Fyous’ technology can shapeshift in under 20 minutes, producing zero tooling waste and making usable parts 14 times faster than 3D printing.

The technology, devised and engineered by Fyous’ co-founders Joshua Shires and Thomas Bloomfield, features more than 28,000 densely packed pins that create the mould. Once the pins are in position, the mould can withstand 6 tonne of distributed pressure. Metamorphic by nature, Fyous says that patent-pending PolyMorphic moulding has the potential to transform the manufacturing industry, reducing waste generated through tooling amends, coupled with faster production times in comparison to 3D printing and traditional mould-making.

By inputting a 3D CAD model, Fyous software generates the PolyMorphic mould shape. The PolyMorphic machine then shapeshifts the mould to create the intended product. On completion of production, the PolyMorphic mould returns to the machine ready for the next shapeshift.

“Our mission is to deliver a revolutionary moulding technology that will disrupt prototyping and manufacturing sectors worldwide,” says Shires. “Using PolyMorphic moulding to create fast, accurate moulds for tooling will reduce time to market for a huge array of products and unlock commercial viability for desirable products which currently have no cost-effective manufacture method.”

He adds: “PolyMorphic moulding is a zero-waste technology where raw materials are conserved and the moulds can be used repeatedly. We will remove not only physical waste in the form of materials and tooling, but also remove wasted time by accelerating product development, prototyping and manufacture efficiencies.”

Rapid grinding in the smallest of spaces

In many applications it is uneconomical to use oversize universal cylindrical grinding machines for the external machining of smaller components. With the new WPG 7 CNC external grinder, Emag Weiss demonstrates another way of grinding workpieces with a maximum length of 250 mm. This very small machine requires only a minimal footprint, but at the same time features a whole range of high-tech components for flexibility and productivity.

The WPG 7 fits on two Euro pallets for easy transportation by crane as an easy to set-up machine. It is then possible to start grinding immediately without compromising on quality or process reliability as the WPG 7 has negligible heat build-up thanks to its rigid design. In addition, in-process measurement with Marposs technology, which works independently of the cycle time during the machining process, is available as an option.

The machine uses straight or angled external grinding wheels (with or without profile) featuring a maximum diameter of 500 mm. It is not possible to integrate an internal grinding wheel and there is no B-axis for swivelling the headstock.

Included in the WPG 7 are features such as highly dynamic axes, a powerful and controllable grinding wheel drive, and a work-head with stationary or live centre (MK4/MK5 or W20/W25). The graphical dialogue interface of the control panel is also important for productivity. It is based on a FANUC control system and considerably simplifies the input of technology parameters for certain cycles. The basic version of the control already includes all common grinding cycles.

Last but not least, Emag Weiss offers the WPG 7 CNC solution with automatic or manual loading.

Nissei showcases indexable insert grinder

Nissei Industry from Japan has been developing vertical and horizontal double-disc grinding machines for more than 40 years. Among other things, these machine concepts are for grinding hard materials, one of the company’s core applications in the Asian market. One specific application is the surface grinding of indexable inserts made of carbide, cermet or ceramic. Nissei presented a machine optimised for this purpose, the VP3-400RW, at the recent GrindingHub exhibition in Stuttgart, Germany.

When grinding indexable inserts, the demands on the mechanical and thermal stability of the processing machine are particularly high. The unit from Nissei has the corresponding rigidity, and this with a comparatively compact design. Thickness variations of the ground indexable inserts with capability values of Cp/Cpk of well over 4 are achievable with dimensions of 6.33 ±0.13 mm, for example.

As the main drives for the two 400 mm diameter diamond grinding wheels, the VP3-400RW contains two AC spindle motors delivering 15 kW each. The internal workpiece feeder, which has a 180° swivel function and linear oscillation, features AC servomotors for high dynamics and fast set-up.

The control of the VP3-400RW is by FANUC, allowing various machining modes such as simultaneous grinding of both sides of the workpiece or grinding of the sides one after the other, as well as grinding of only one side. It is possible to store and automatically call-up the respective machining parameters for different types of indexable inserts. Another important feature is the fully automatic dressing device, which can correct the shape on both grinding wheel surfaces simultaneously if necessary.

Nissei presented the VP3-400RW at GrindingHub as a co-operation partner of Nagel.
