Laser machining with added value - the LaserSmart 510 is not<br />

only extremely fast, but also offers the option to sharpen<br />

carbide endmills with CVD coating<br />

Dream surface qualities!<br />

When it was unveiled, it caused a sensation: The completely<br />

redeveloped six-axis GrindSmart ® 830XW was the<br />

first tool grinding machine to combine the benefits of<br />

linear motors on x-, y- and z-axes with hydrostatics. The<br />

product was impressive not only on paper but also in practice,<br />

as proven by the positive feedback from users who<br />

deployed this exceptional tool and cutter grinder in production.<br />

Damien Wunderlin: “Our goal was to further<br />

reduce friction within the machine and ensure near-zero<br />

wear. We have eliminated residual friction by combining<br />

this with a hydrostatic system and effectively dampened<br />

vibrations. And, judging by the feedback from our customers,<br />

it seems that our approach has worked. The concept<br />

offers longer lifetime of the grinding wheels, produce<br />

perfect surfaces and cutting edges and, above all, ensure<br />

highly stable production processes - a key USP in the highquality<br />

segment.”<br />

A longer life thanks to a sharp CVD edge<br />

The one virtue of diamonds that machinists love but that<br />

can cause headaches for tool manufacturers is their hardness.<br />

While the geometry variants in PCD-equipped or<br />

CVD diamond tools were rather restricted due to the hardness,<br />

this field is being explored again since the launch of<br />

the LaserSmart 510, the latest-generation laser cutting machines<br />

from Rollomatic. The laser opens up undreamedof<br />

possibilities such as extremely sharp cutting edges with<br />

radii of 0.001 mm or less. This highly productive technology<br />

delivers outstanding quality and can speed up machining<br />

times fourfold. “The fact that our machine completes<br />

the entire process in a single step saves time and significantly<br />

increases productivity,” said Sven Peter, laser<br />

product manager at Rollomatic. “While it used to be almost<br />

impossible to create sharp and defined cutting edges<br />

on CVD-coated hard metal tools with repeat accuracy, this<br />

is no longer a problem thanks to our new lasering technology.<br />

This opens up entirely new application fields for this<br />

type of tool.”<br />

Well trained, optimally operated<br />

It is not the grinding machines alone that ensure efficiency<br />

and highly desirable tools, but first and foremost the people<br />

who design these tools and deploy them highly effectively<br />

on the Rollomatic machine. “Since it is becoming increasingly<br />

difficult to find high-quality, skilled personnel, we<br />

have launched a comprehensive, modular tool grinding<br />

training program,” says Damien Wunderlin. As part of this<br />

program, Rollomatic offers numerous courses each year<br />

con ducted by highly qualified, multilingual experts, both<br />

on the customer's premises as well as at its training centers<br />

in Switzerland, the USA, Japan, Taiwan, Thailand and<br />

China. The courses cover everything from grinding and<br />

maintenance to lean production, laser technology and robotics.<br />

Whether GrindSmart ® , GrindSmart ® Nano, Laser-<br />

Smart or ShapeSmart ® , special learning units and qualification<br />

levels have been created for all Rollomatic types.<br />

“This means that everyone gets their money's worth, whatever<br />

their level of knowledge. Our specialists have shown<br />

many an expert operator who thought they knew ‘their’<br />

machinery inside and out lots of little tricks that have occasionally<br />

led to a decisive breakthrough in tool design or<br />

the grinding process,” states Damien Wunderlin happily.<br />

A visit with added value<br />

Rollomatic has developed an impressive portfolio of tool<br />

grinding solutions as well as innovations in laser technology<br />

and cylindrical grinding. “Fast-moving sales markets,<br />

new competitors and personalized products require more<br />

flexible production systems - and a faster response to customer<br />

requirements. This is why we have created a complete<br />

package focusing on outstanding precision and value.<br />

By combining these products with smart automation solutions,<br />

customers can now build a production environment<br />

that is autonomous and highly efficient and delivers ultrahigh<br />

quality,” says Damien Wunderlin.<br />

The ShapeSmart®NP50 cylindrical grinding machine offers<br />

greater flexibility, faster configuration and improved surface<br />

qualities. It can also be easily connected to other Rollomatic<br />

grinding machines to form a “smart factory network”<br />
