B2-K1026 CNC Follower Type Eccentric Shaft Grinding Machine

The B2-K1026 CNC follower-type eccentric shaft grinding machine is a high-end CNC grinding machine independently developed by our company. This machine uses advanced follower-type (cutting point tracking) grinding technology. By controlling the X-axis (wheelhead) and C-axis (workpiece rotation) with closed-loop control, it achieves simultaneous grinding of the eccentric diameter and the main shaft journal in a single clamping. It offers agility, flexibility, high efficiency, and precision, making it ideal for use in eccentric shaft production lines and precision mass processing. This machine solves the shortcomings of traditional eccentric fixtures such as poor flexibility and complicated adjustments, significantly improving machining accuracy and efficiency. It is primarily used in the precision machining of eccentric shafts in industries such as robotics, compressors, reducers, and general machinery.
