MODERN EQUIPMENT REVIEW Modern Machine Shop 107 SPOTLIGHT | Turning Improved Turning Center Features Fast Gantry Traverse Rates Murata Machinery USA has introduced the MW120II turning center, an improved version of the MW120. The machine feature's Muratec's latest and fast- est-ever automation, the company claims. Armed with a high-speed, lightweight gantry loader, the MW120II offers rapid traverse speeds in the X, Y and Z axes of as much as 1.5 times faster than those of the tradi- tional gantry loader, according to the company. In addition, the MW120II improves machine idle time compared to the traditional machine. Overall idle time reductions related to turret clamp/unclamp, chuck clamp/unclamp, and higher-speed shutter doors have resulted in load/unload time reductions of more than 3 sec. per part. Like other Muratec machines, the flexible automa- tion enables the combination of multiple machines into a single production cell, utilizing common transfer, turnaround and feeding units to serve the machines and provide an efficient production solution. | Murata Machinery USA Inc. | 704-875-9280 muratec-usa.com Hard-Turning Grades Excel in Automotive Transmission Applications Sandvik Coromant's CB7125 and CB7135 grades are said to enable the performance of medium-to- heavy interrupted cuts and removal of the hardened layer (depth of cut up to 2 mm) in case- and induc- tion-hardened steel components, typically for the automotive industry. For these applications, the two new grades offer longer and more consistent tool life, good levels of surface finish and consistent dimensional tolerances. The company says that those working with transmission and other hard-turned components can benefit from these grades, namely through added speed and a more secure edge line for lower cost per component. The two grades are optimized for turning steel materials with a hardness of 58 to 62 HRC. Designed for medium intermittent cutting, the CB7125 grade features a PVD coating that provides improved wear and fracture resistance for extended tool life. This grade, which contains medium CBN content, is ideal for turning shaft splines and shafts with chamfered oil holes or pockets. | Sandvik Coromant Inc. | 201-794-5000 sandvik.coromant.com techspex.com Search Machines Smarter.
