Product Description:

The PX-MAF230M-3TB-A is a high-speed heavy-duty machining motor where cutting stability and speed are a necessity. Built with rapid traverse in mind, it offers full travel positioning in only 3 seconds, which enhances productivity quite substantially by reducing non-cutting time. This ability for fast motion allows for faster turnaround of jobs in situations where even seconds make a difference in production efficiency.

Its construction also features capacity to accommodate the turning capacity of 4.4 mm², and due to that, it accommodates applications calling for even, smooth cutting of heavy-to-medium parts. Its construction is a next generation solution for saving cycle time with up to 20% of total machining time less than on prior generation motors in comparable configuration. This benefit is provided by the marriage of enhanced mechanical efficiency, better internal component design, and intelligent heat management to reduce loss of performance during operation under extended operation cycles. Integrated features such as vibrations dampening and strong torque output produce high-precision tool paths and high-finish surface finishes despite operation at increased speeds. The unit is likely to be used in high-end machine platforms where lower energy consumption and improved performance ratios are the priority.

With its blend of high speed positioning and stable torque delivery, this motor not only optimizes throughput but also gives life to the system in the long run by minimizing mechanical wear and shock load. The PX-MAF230M-3TB-A's focus on power density, time-to-market effectiveness, and cutting integrity makes it a critical solution for manufacturers who need to meet aggressive schedules without sacrificing part quality. Wherever integrated into a turning center or a multi-axis machine platform, it conforms to design principles of high-speed motion with optimized machining.
