Methods Machine Tools, Inc. has introduced the YASDA YMC 430 Ver. II, a new Micro Machining Center that is ideal for the ultra-precise manufacturing and high surface finishes required on small, complex features in components and dies / molds in industries such as medical and semi-conductor.
Linear motor-driven controlled axes and a highly rigid machine structure offer users the highest speed, precision and surface quality machining in its class. The YASDA Micro Center YMC 430 Ver. II has a high-speed 40,000 RPM spindle and is available with 3-Axis or 5-Axis capabilities.
"We are very pleased to offer our customers who manufacture molds and components with challenging, micro-sized angles and geometry with a hard milling solution from YASDA, the ultimate precision machine manufacturer," said Mr. Steve Previti, YASDA Product Manager. "A highly rigid symmetric frame design and unique thermal distortion stabilizing system provide consistency and repeatability, to assure users unsurpassed high accuracy." Linear positioning and circularity accuracy of less than one micron (according to ISO 230-2 1997) is achieved.
The HSK-E32 spindle on the YMC 430 Ver. II is designed and manufactured by YASDA to minimize vibration and offer high reliability and repeatability in micro milling applications, including roughing to finishing on hardened steel and other exceptionally hard materials. A symmetrical H-shaped column and a low center of gravity structure provide high rigidity to the YMC 430 Ver. II machine structure.
The YMC 430 X-Y table has linear guideways and a linear motor drive, enabling highly precise machining and excellent vibration dampening. Linear motor drives include optical scales that support and sustain submicron milling performance.
In the optional 5-Axis micro milling capability, the YMC 430 is equipped with a direct drive motor-driven, high-precision tilting rotary table. This combination provides multi-face indexing and machining as well as simultaneous 5-Axis machining without re-chucking. Applying the direct drive motor to a tilted and rotary axis creates backlash-free, high-speed, high-precision positioning.
The YASDA Micro Center YMC 430 Ver. II has X,Y,Z travels of 16.5" x 11.8" x 9.8" (420 mm x 300 mm x 250 mm), respectively. The table work surface measures 23.6" x 13.8" (600 mm x 350 mm). An automatic tool changer holds 32 tools and is available in a 90-tool, large-capacity configuration. The powerful, FANUC 31i-Model B5 control is furnished standard.
