OKK USA Corporation’s VB53 design features help achieve superior surface finish and precision, combined with high speed operation and excellent operator accessibility, to satisfy even the most high end mold application challenges.
The VB53 is standard with 20000RPM spindle with big plus double contact, X-axis travel of 41.34”, Y-axis travel of 20.87, Z-axis travel of 20.08”. The VB53's superior surface finishing capability, fewer vibration stripes by accel and decel, and less quadrant projections distinguishes itself amongst the competition through a number of technological innovations. OKK's Fine Pitch ball screw reduces the maximum rapid speed, but increases the overall precision of the entire system along with a rigid machine base. Additionally, the VB53 employs an external, isolated oil cooler, which removes a common source of vibration from the machine, resulting in superior die quality the company states.
Countermeasures for thermal displacement which provide superior precision capability are another advantage of the VB53 over conventional machines. Cutting chips and coolant often affect the thermal displacement of machining centers. Our coolant shelter prevents the casting from being exposed to either, providing optimal performance.
Additionally, standard equipment like the 0.05 micron scale feedback linear scale enhances the positioning accuracy through all possible applications.
