MICRO CENTER FOR LARGE PART MACHINING

The success of Yasda Precision America Corporation's (Elk Grove Village, IL) YMC325 Micro Center has prompted the company to develop a second machine with higher accuracies and capacities. Boasting the same robust construction, linear motor drive for all axes and advanced features as the YMC325, the new YMC430 Micro Center is also equipped with newly developed linear ball guide ways and a larger table-working surface.

For the highest surface quality and precision, the YMC430's linear guide way consists of 8 rows of small balls and a longer bearing case than a conventional linear ball guide way. More contact creates improved stiffness for damping and straightness capabilities.

Allowing for large work piece capacities, the YMC430 travels are 400(X) mm x 300(Y) mm x 250(Z) mm, table size is 450 mm x 350 mm and table loading capacity is 100 kg.

As with the YMC325, the YMC430's non-physical contact and high servo response drive eliminate backlash and ensure long-term operation. To reduce thermal distortion, the Micro Center is equipped with a thermal distortion stabilizing system. A gas pressure balancer improves motion accuracy and stabilizes balancing for Z-axis.

The YMC430 features a thermally symmetric and low gravity structure. Due to reduced vibration, high acceleration/deceleration motion and high dynamic response on axial motion are achieved. A low friction cover further improves axial motion and feed stability. The highly rigid column of the YMC430 minimizes vibration on the Z-axis motion, while rigid bed provides consistent accuracy over time. Peripheral devices of the YMC430 are separated and isolated from vibration and heat.

Consistent with the YMC325, spindle speeds reach 40,000 rpm, rapid travel 20,000 mm/min and feed rate 10,000 mm/min (HAS-3).
