Chicago, Illinois, December 14, 2011 – Mori Seiki has started taking orders for the ULTRASONIC 65 monoBLOCK® equipped with ultrasonic machining functions and the LASERTEC 65 Shape equipped with laser machining functions. Both machines are designed based on the DMU 65 monoBLOCK ® 5-axis control machining center made by Mori Seiki’s collaboration partner, GILDEMEISTER AG of Germany. The DMU 65 monoBLOCK ® is part of the new DMU monoBLOCK ® series of next generation machine tools with excellent cost performance. The DMU 65 monoBLOCK ® uses a 2-axis trunnion table *1 for the first time in the DMU monoBLOCK ® series, handling large workpieces of up to 2200 lbs. The machine features a compact design with a footprint of 24.6 ft 2, as well as a large door with an opening width of 56 in. The expansive door opening offers a wide work area and improved access to the machine. It also allows easy access for loading and unloading large workpieces by crane. These two machines have been launched in response to customer demand for 5-axis machining of difficult-to-cut materials such as ceramic and super hard metals while maintaining fine cutting and environment-friendly machining. And there has also been growing demand for 5-axis machining center, as the workpieces become more complicated. Each of the newly released 5-axis machining centers improves productivity and cost performance by performing multiple processes that usually require special machines.
ULTRASONIC 65 monoBLOCK ®
The ULTRASONIC actuator system used on the spindle is a patented technology of GILDEMEISTER, allowing a 5-axis machining center to perform ultrasonic machining through HSK interface. Ultrasonic machining reduces cutting forces by applying longitudinal ultrasonic vibration to rotational movement of a tool during grinding. For this reason, ultrasonic machining can significantly improve machining quality in regards of surface finishes of less than Ra *1 0.2 µm as well as reduction of micro-cracking of extremely hard, but brittle material including glass, ceramic and super hard metal. Ultrasonic machining is also a process that attracts attention from the dental prosthesis market including manufacturing of artificial teeth and implants, but the ULTRASONIC 65 monoBLOCK ® can also handle much larger workpieces. The machine is suitable for grinding glass ceramic lenses for artificial satellites, parts for semiconductors and aircraft engine parts made from Carbon Silicon *2 or Nitric Silicon *3 . The ULTRASONIC 65 monoBLOCK ® realizes high-efficiency machining of large-diameter workpiece of high-tech materials by integrating 5-axis milling and ultrasonic machining.
LASERTEC 65 Shape
By mounting a fiber laser scanning head on the spindle through the HSK interface, laser surface texturing can be performed on a 5-axis machining center. Surface texturing is a machining method used to produce various patterns such as wood grain and leather grain on workpiece surfaces. The LASERTEC 65 Shape opens up new possibilities by enabling more complex geometrically defined 3D-structures in free-forms. Laser surface texturing allows the user to create nearly unlimited wide variety of patterns (including customized 3D-textures) with greater accuracy than conventional etching in shorter machining times. It can also recreate the same pattern repeatedly. Furthermore, laser surface texturing is also an environmentally friendly machining method, especially when compared with etching, which uses chemicals and generates industrial waste.
Offering both cutting and lasering on one machine, the LASERTEC 65 Shape is capable of handling the entire machining process from roughing to laser surface finishing, and is an ideal solution for die and mold making. The LASERTEC 65Shape provides complete machining for a wide range of dies and molds including injection molds and interior automobile components.
Additionally, the intelligent cross-process LASERSOFT-3D-TEXTURE software enables the machine to expand the range of surface texturing design variations. Monochrome image data in bitmap format *4 printed images, as well as individually newly designed 3D-textures, can be converted into laser machining programs. The programs can be seamlessly projected onto large or free-form surfaces. The machine also features the 3D collision checking and automatic programming functions as standard, ensuring simplified operations and efficient 5-axis laser machining.
