New 4kW Fiber Laser Cuts Copper, Brass, Titanium

JDSU today announced that it has collaborated with Amada, a leading manufacturer of machine tools for metal fabrication, to develop a new high-power 4 kilowatt (kW) fiber laser. The fiber laser has been integrated into a new sheet metal cutting system that Amada plans to start selling to the Japanese market in May 2011, followed by a global market introduction in June 2011. According to Amada, the new system will provide the fastest linear cutting speed available worldwide.

The new 4 kW fiber laser provides the ability to cut materials such as copper, brass, titanium and non-metals that cannot be cut effectively with traditional carbon dioxide (CO2) lasers. Combined with the Amada high-speed linear drive system, thin sheets of stainless steel and aluminum will be cut at a linear speed that is 2.5 to 3 times faster than cutting speeds achieved with traditional CO2-based cutting systems.

Metal processing is one of the largest markets for lasers, with fiber lasers gaining traction in recent years. Industry analyst firm Strategies Unlimited estimates that the laser market for kilowatt materials processing will grow to more than $1 billion by 2013.

Fiber lasers offer several additional benefits over CO2 and solid-state lasers for sheet metal processing applications, including:

  • Flexible beam delivery via a process fiber
  • Significantly reduced electrical power consumption
  • Reduced footprint
  • Low maintenance costs
  • Ability to focus the beam effectively from a long working distance

“Amada’s long-standing machine tool design and manufacturing expertise combined with JDSU’s telecom-grade diode and fiber laser technology have enabled us to design a fiber laser that is not only cost effective, but that also provides industry leading performance and reliability,” said Ken Lo, vice president and general manager of Commercial Lasers at JDSU.

“The strong collaboration and complimentary expertise of the teams at Amada and JDSU have been instrumental to developing the new 4 kW laser,” said Mr. Naoki Orita, corporate officer and director of the Research Laboratory at Amada.

Amada plans to preview its new sheet metal cutting system including the new 4kW fiber laser at the EuroBlech Sheet Metal Exhibition in Hannover, Germany from October 26 – 30, 2010.

Kennametal's Cardoso Reports 42% Metalworking Group Sales Increase in North America

"Our fiscal 2010 fourth quarter performance clearly reflects that we are realizing continuing sales growth and higher incremental margins," said Carlos Cardoso, Kennametal's Chairman, President and Chief Executive Officer. "Our talented global workforce continues to successfully implement our strategies through their efforts and dedication."

  • Metalworking Solutions & Services Group (MSSG) sales increased by 44 percent from the prior year quarter, driven by organic growth of 43 percent and favorable foreign currency effects of 1 percent. On an organic basis, sales in Latin America, Asia Pacific and India increased 66 percent, 65 percent and 64 percent, respectively. North America and Europe reported organic sales increases of 42 percent and 34 percent, respectively, compared with the prior year quarter. Sequentially, sales increased by 8 percent as global industrial production continued to improve. This represents the fourth consecutive quarter of sequential sales growth for MSSG.
  • MSSG operating income was $45 million compared with an operating loss of $29 million for the same quarter of the prior year. Absent restructuring and related charges recorded in both periods, MSSG operating income was $57 million compared with an operating loss of $16 million in the prior year quarter. The primary drivers of the increase in operating income were higher sales volumes and improved capacity utilization, cost savings from restructuring programs and continued cost containment. MSSG adjusted operating margin improved sequentially from the March quarter by 580 basis points to 18.1 percent from 12.3 percent.
  • Advanced Materials Solutions Group (AMSG) sales increased 34 percent from the prior year quarter, driven by 33 percent organic growth and 1 percent favorable foreign currency effects. The organic increase was primarily driven by higher sales of mining and construction products, as well as increased demand for energy related and engineered products. Sequentially, sales increased by 11 percent, driven by better performance in all AMSG end markets.
  • AMSG operating income was $43 million, compared with $14 million in the same quarter of the prior year. Absent restructuring and related charges recorded in both periods, AMSG operating income was $45 million in the current quarter compared with $18 million in the prior year quarter. Operating income improved primarily due to higher sales volumes, cost savings from restructuring programs and continued cost containment. For the second consecutive quarter, AMSG adjusted operating margin increased sequentially by 150 basis points to 19.9 percent from 18.4 percent in the March quarter.

Kennametal's restructuring programs continue to remain on track to deliver the anticipated annual ongoing pre-tax permanent savings of $155 million to $160 million once all programs are fully implemented. The cumulative total pre-tax charges are expected to be approximately $160 million to $165 million. As previously mentioned, total restructuring and related benefits realized in fiscal 2010 were approximately $137 million while the related charges recorded inception-to-date were approximately $128 million.

The company's outlook for fiscal 2011 assumes that the global economy and worldwide industrial production will continue to gradually improve and that overall economic trends will remain in positive territory. As a result, the company expects to experience positive growth during the fiscal year in all geographies, albeit more modest growth in our served European markets.

New multi-feed honing technology offers choice of tool feed methods to optimize cycle time, abrasive life, part finish

Sunnen's new multi-feed technology gives honing process users a revolutionary choice of tool-feed schemes to achieve the shortest cycle times, lowest part cost, and longest abrasive life. Multi-feed technology is available as an option on new machines in Sunnen's SV-1000 and SV-500 Series, as well as a retrofit for existing machines in these series.

Sunnen's new patented multi-feed honing technology gives users a revolutionary choice of tool-feed modes to achieve the shortest cycle times, lowest part cost, and longest abrasive life. Multi-feed combines Sunnen's new controlled-force tool-feed with its controlled-rate feed system. The two different tool-feed modes allow the user to select the better option to suit the workpiece geometry, material and tool type/size. Multi-feed technology will be demonstrated at IMTS, and is available as an option on new machines in Sunnen's SV-1000 and SV-500 Series, as well as a retrofit for existing machines in these series.

Controlled-force honing, a new feature in multi-feed, works like cruise control to ensure the optimum cutting load on the honing abrasive throughout a cycle, irrespective of the incoming part's hardness, geometry or size variation. Depending on the application, controlled-force honing cuts cycle times by as much as 50 percent, lengthens abrasive life for lower consumable cost, and allows finer control of surface finish parameters than ever before possible. Controlled-force technology eliminates glazing of the abrasive, due to too little force, and maintains a steady, free-cutting, self-dressing condition for maximum metal removal in the shortest possible cycle time.

"In our development work, we found that more-durable abrasives could often be used, resulting in more parts per set of abrasives and lower cost per part," said Dennis Westhoff, Sunnen's Global Business Development Manager. Controlled-force is an ideal choice for applications using segmented diamond or superabrasive honing tools, or where incoming workpieces have slight variations in hole diameters, hardness and geometry. "An established honing process can be thrown off balance because of incoming part variations caused by upstream machining, heat treating or plating," Westhoff explains. "Controlled-force honing always maintains optimum feed force on the honing abrasive under these conditions to eliminate wasteful "air cutting," glazing or tool damage. The beauty is that if conditions allow, for example with a batch of parts requiring less stock removal, the honing cycle will be shortened significantly and automatically." Controlled-force's ability to control the cutting load within a very fine range also allows much tighter control of final surface finish parameters. "We have been able to cut the variation of final surface finish measurement by half or more," Westhoff added. Controlled-force honing works with Sunnen's MMT, PH and new KRQ tools.

Controlled-force honing is an enhancement of Sunnen's controlled-rate system for tool wear compensation, which is already capable of adjusting tool size in increments as fine as 0.1 µm (0.000010"). Controlled-rate tool feeding is typically used with plated-diamond CGT honing tools, which use a sleeve of abrasive for full contact with the bore surface. CGT tools are frequently used on cast iron and powder metal workpieces, segmented bores, or parts with multiple lands, ports, keyways or crossholes in the bore. Sunnen's machine control provides up to five feed expansion profiles that can be used during a cycle for rapid part touch, cutting, sizing, finishing and spark-out.
