ConditionNew
New
• The rotary table is designed with hydrostatic bearings, which support the worktable through a uniform oil film, providing the mechanism with high vibration resistance and higher rotational precision than conventional bearings
• Adaptive finish program to adjust table rotation, infeed speed and grinding wheel speed for better finish
• The spindle is supported by six Class 7 (P4), ultra-precision angular contact ball bearings that can withstand heavy-duty grinding
• In-machine Dynamic Balancing allows operators to adjust the grinding wheel balance and limit wheel vibration to less than 1 um
• The brand-new spindle elevating mechanism and front-to-back transmission mechanism of the machine are equipped with linear guideways and ballscrew, combined with servo motor for direct transmission
• Optimized structure for maximum rigidity for maximal precision and efficacy
