Cutting tool manufacturer Sandvik Coromant (Fair Lawn, New Jersey) has expanded its Sustainable Manufacturing Program, which was originally developed to help Japanese-based companies reduce electricity consumption by 15 percent in the aftermath of the recent earthquake and the resulting lack of available electrical power. According to the company, the program is a three-pronged approach that provides energy reduction through Sandvik cutting tool technology, application techniques and productivity increases.
The company offers examples of all three aspects of this approach. First, the use of milling cutters such as the CoroMill 390 and 490 can decrease electricity consumption by as much as 20 percent compared to conventional, positive 90-degree cutters, the company says. Likewise, applying high-pressure coolant can reduce downtime and the need for electricity by solving problems with unmanageable chip curls. Finally, applying wiper inserts to existing tools can decrease electricity usage by shortening the time in cut by as much as 50 percent compared to standard ISO inserts.
