SHOP SOLUTIONS “The laser generates geometries, fi nishes, and edge
preps that would otherwise be very diffi cult or even im- possible to produce with CNC grinding,” said Chambers. “When it comes to edge preps for instance, conventional grinding can produce sharp edges in the range of 5–10 μm. Laser machining, on the other hand, can produce edges in the 1.5–5 μm range. The noticeably increased sharpness is a signifi cant advantage for us.” Conversely, the laser beam can round an edge to provide
extra strength and do so in a single operation, which is equivalent to combining CNC grinding with a secondary hon- ing operation. The Laser Lines can also produce chamfers and other 3D edge geometries.
Customers use Shape-Master tools to machine com- ponents made from materials ranging from cast irons and steels to depleted uranium, aluminum alloys, and composite
materials for a variety of industries that include automotive, aerospace, energy among others. According to Chambers, Shape-Master has produced tools for space exploration components as well as com- ponents for US defense systems. He also said that a lot of the shop’s aerospace customers work with composites and exotics, and he believes those types of materials will continue to make their way into the automotive industry for weight reduction and fuel effi ciency as well. “Our repeat customers would recommend us because of our high-quality products, service and employees,” said Chambers. “We cater to all the needs of our customers, and we have invested a lot of capital in technology, inspection equipment, and fi nishing equipment to be able to do so and to compete with and provide better products than the com- petition. That’s what our customers expect, and that’s what our EWAG machines help us deliver.” For more information about United Grinding North America, go to

EWAG’s tangential laser beam machining process generates cutting tool edges and geometries by shaping tool surfaces using the outer surface of the laser beam in ultra-short, 10-pi- cosecond pulses that directly vaporize material without any signifi cant heat generation.
