Micromachining center achieves precision, repeatability required to produce medtech molds

A new micromachining center from Japanese machine builder Yasda is designed for the manufacture of molds and components with challenging micro-sized geometries that are typical in the medical and semiconductor sectors, for example. The new Yasda YMC 430 Ver. IIA is distributed in the United States by Methods Machine Tools Inc. (Sudbury, MA).

Yasda micromachining centerLinear-motor-driven control axes and a rigid machine structure impart speed and precision to the machine, according to Methods Machine Tools. The system achieves micrometer-level accuracy in linear positioning and circularity, and comes equipped with a 40,000-rpm spindle designed and manufactured by Yasda to minimize vibration and ensure reliability and repeatability in micromilling applications. The YMC 430 Ver. IIA is available in three- or five-axis versions.

Linear guideways and a linear motor drive enable precise machining and excellent vibration dampening, says Yasda. The linear motor drives include optical scales that support and sustain submicron milling performance.

In the optional five-axis micromilling version, the YMC 430 is equipped with a direct-drive, high-precision tilting rotary table. This combination provides multi-face indexing and machining as well as simultaneous five-axis machining without rechucking. 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 features x, y, and z travel lengths of 16.5 x 11.8 x 9.8 in. (420 x 300 x 250 mm). The work surface measures 23.6 x 13.8 in. (600 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 standard.
